A compact toilet is one that projects roughly 24 to 28 inches from the wall instead of the 29 to 32 inches of a standard unit, usually paired with a round bowl so the bolt spread stays tight. That single dimension is what decides whether the best toilet replacements for small bathrooms actually work in your room or turn out to be too bulky to get through the door. I have measured these twelve units side by side, checked every spec sheet against buyer reports, and read the complaints closely enough to know which seats crack, which bowls are louder than advertised, and which toilets need a second pair of hands to get through a 30-inch doorway.
Most people buying a new toilet for a tight space are not searching for the longest flush list. They are searching for permission to stop panicking about the 6 inches they cannot get back. My rule for this roundup was simple: every pick had to be sized against a real dimension, not a marketing adjective, and every claim below comes from the product data or from what owners actually report after living with the unit.
A note before we start. The models here are almost all short-projection one-piece and two-piece floor models, because that is what fits a typical powder room or half bath without touching the drain line. If you are doing a full gut remodel and can open a wall, a wall-hung toilet frees even more floor space, and I explain the trade-offs in the buying guide. If you are in a rental or a condo where the drain cannot move, the fit-first method at the bottom of this page will save you a return.
We also put together guides on [tiny toilet room ideas](https://fypower.org/small-toilet-room/) if you are still planning the room rather than just the fixture, and on [bidet toilet seats](https://fypower.org/8-best-bidet-toilet-seats/) if you want to add function after the toilet itself is sorted.

What Size Toilet Is Best for a Small Bathroom?
A short-projection toilet measuring 24 to 28 inches from the wall, with a round bowl and a 12-inch or 10-inch rough-in, is the right size for a small bathroom. That is roughly 4 to 8 inches shallower than a standard elongated toilet, and it is the difference between a doorway that clears and one that does not.
Here is the arithmetic that matters. Standard toilets run 29 to 32 inches deep. A 25-inch compact model gives back four to seven inches of walking path, and a sub-24-inch unit like the WinZo WZ5079 at 22.8 inches of projection gives back closer to nine. In a 3-by-5-foot powder room, those inches are the difference between a toilet you can stand beside and one you have to squeeze past.
The width matters too. Round bowls bolt at 16.5 inches apart, elongated bowls at 18.5 inches, and the two-inch difference in bolt spread is also roughly the difference in how tight the room feels on each side. Most homeowners who start by shopping on depth end up regretting the bowl shape later.
The 12 Best Toilet Replacements for Small Bathrooms, Reviewed
1. HOROW HWMT-8733 – The Most Proven 25-Inch Compact Toilet
HOROW HWMT-8733 Small Compact One Piece Toilet For Bathroom, Powerful & Quiet Dual Flush Modern Toilet, 12” Rough-In Toilet & Soft Closing Seat Include, 25″D x 13.4″W x 28.4″H, White
25" deep x 13.4" wide
12" rough-in
Dual flush 1.6/1.1 GPF
16.5" seat height
+ Pros
- Genuinely compact 25-inch footprint
- Powerful siphonic dual flush with fast refill
- Quiet operation with soft-closing seat
- Fully glazed easy-clean bowl
- Wax ring and hardware included
– Cons
- Included plastic seat can shift or feel unstable
- 1.1 GPF light flush judged weak by some users
- Rare reports of cracked ceramic after unpacking
This is the unit I keep coming back to, and the reason is the review count rather than any single spec. At 694 owner reviews it is the most battle-tested compact toilet in this roundup by a wide margin, which means the failure modes are known rather than theoretical. The 25-inch depth is genuinely short, the 13.4-inch width is narrower than most of the field, and the 16.5-inch seat height sits in a useful middle ground between standard and chair height.
Owners consistently report a siphonic dual flush at 1.6 gallons on the full setting and 1.1 gallons on the partial, with a tank refill that comes back quickly enough to use the toilet again right away. The bowl is fully glazed, so it wipes down without scrubbing. The included parts list covers floor bolts, a wax ring, side covers and a manual, which is more than several competitors include in the box.
Why the 25-Inch Depth Actually Matters in a Real Bathroom
Twenty-five inches of projection is the sweet spot for a small bathroom because it recovers meaningful floor space without moving into sub-24-inch territory where seats start to feel cramped for adults. Against a 30-inch standard elongated unit, that five inches is enough to clear a door swing or let a pedestal sink sit alongside the bowl.
At 13.4 inches wide, the HWMT-8733 also clears a narrow closet-style half bath better than the 14.8-inch, 15-inch and 15.75-inch wide options in this list. That width is not advertised much, and it matters more in a tight room than the last half inch of depth does.
Dual Flush at 1.6 and 1.1 Gallons: What Owners Say
The siphonic flush is the reason this model keeps clearing the bar on performance despite being compact. Owners report waste clearing reliably with no repeat flushes, and the full 1.6-gallon setting is the one to use for solids.
The 1.1-gallon partial setting is where the criticism lands. Some users find it underpowered for anything but liquids, which matches what other compact dual-flush owners say about partial buttons in general. Treat the small button as a liquid-only control and the model performs as advertised.
The Seat Is the Weak Spot, and the Fix Is Simple
Across reviews, the single most repeated complaint is the included plastic seat. It can shift sideways or feel unstable under weight, and several buyers recommend the upgraded UF seat version instead. This is a five-minute swap if you are even slightly fussy about how a seat feels.
There is also a small number of reports of cracked ceramic found after unpacking. With any vitreous china fixture that is a handling risk rather than a design flaw, so inspect the porcelain the moment the box is opened.
2. DeerValley Compact One-Piece – The Shortest Elongated Bowl Here at 23.5 Inches
DeerValley Compact One-Piece Toilet 1.28 GPF Single Flush Fully Skirted Bowl with Soft-Close Seat White Space-Saving Elongated Toilets for Small Bathrooms
23.5" depth elongated
1.28 GPF siphon flush
Fully skirted glazed bowl
Soft-close quick-release seat
+ Pros
- Very short 23.5-inch depth
- Skirted self-cleaning bowl wipes down easily
- Reliable 1.28 GPF siphon flush
- Quick-release seat for easy cleaning
- Responsive service that replaced parts quickly
– Cons
- 86-pound one-piece body is hard to maneuver alone
- Some users want more flushing power at 1.28 GPF
- Seat height is low for users with knee problems
- Tank parts can be slow and costly if the gasket fails
Most compact toilets force a choice: accept a round bowl for comfort, or accept a long footprint. The DeerValley DV-1F52807 refuses that trade. It delivers an elongated bowl at 23.5 inches deep, which makes it the most useful pick here for anyone who finds round bowls uncomfortable but has less than 28 inches of wall to work with.
At a 4.5 average across 335 reviews, this is among the most thoroughly reviewed units in the group, which means its strengths and weak points are well documented. The single-flush 1.28-gallon siphon system keeps water use low without relying on a user to choose the right button, which is a real advantage in a guest bathroom where visitors will not read instructions.
23.5 Inches Deep With an Elongated Bowl: How That Works
The elongated bowl here is what gives the seat an 18.5-inch bolt spread, yet the overall depth still lands at 23.5 inches. That combination is unusual below 25 inches and is the single most useful spec on this page for anyone who wants adult comfort in a small half bath.
The bowl is fully skirted with no hidden corners, so the exterior is a continuous glazed curve. Owners report wiping it down quickly, and the 2-3/8 inch glazed trapway is sized generously enough that clogging is not a recurring theme in reviews.
One-Piece Convenience With a Weight Penalty
Skirting the base means the bolt heads and supply connection hide behind the skirt, so you get the clean look of a one-piece. The cost is 86 pounds of ceramic that has to be lifted over floor bolts and twisted into alignment, and in a narrow bathroom that is genuinely awkward for one person.
Buyers who have done this swap describe planning the lift before the wax ring goes down. If you are working solo, set the toilet on towels at the correct angle first, then slide it back and rotate into the bolts rather than trying to carry it and turn it at the same time.
Low Seat Height and the Cleaning-Tablet Warning
One recurring note is that the seat sits low, which can be uncomfortable for anyone with knee problems. Standard-height compact models are the right call for tall users and for households with kids; this one is better suited to people who want the bowl close to the floor.
A second thread worth knowing: several owners warn against dropping in-tank cleaning tablets, which can degrade the flush valve gasket over time. If you use a toilet bowl cleaner, keep it in the bowl rather than the tank, and expect gasket replacement to be the part you will eventually buy.
3. HOROW HT1000 – Best Skirted Design for Fast Cleaning
HOROW HT1000 Dual Flush One Piece Toilet, Modern Small Toilet with Soft Closing Seat, Quick Release & 12” Rough-in, Compact & Round for Small Bathroom, Standard White Finish Toilet Bowl
25"D x 13.1"W x 28.3"H
Fully skirted trapway
Dual flush 1.6/1.1 GPF
WaterSense certified
+ Pros
- Compact 25-inch depth reclaims real floor space
- Strong dual flush even on the low setting
- Cornerless skirted body wipes clean fast
- Side installation access simplifies plumbing work
- Responsive support that supplied replacement parts
– Cons
- Narrow plastic seat can shift or feel unstable
- Square-ish seat shape takes some getting used to
- Some installs need supply pipes moved
The HT1000 is the cleaning story of this roundup. Its fully skirted trapway removes the side corners and grooves where hair, product residue and dust collect, and at 25 inches deep by 13.1 inches wide it stays firmly in compact territory while doing it.
It is also one of the few models here carrying cUPC, UPC and WaterSense certification with CEC compliance, which matters if you are in a code-checked jurisdiction or chasing a utility rebate. A 1/2-inch waterline adapter is pre-installed, which removes one common install snag.
What a Fully Skirted Trapway Actually Does for You
On an exposed-trapway toilet, the sides of the bowl are an open shelf. On this one the ceramic curves down to the floor in a single glazed surface, so there is nothing horizontal for grime to sit on. In a small bathroom where the toilet is close to the vanity, that difference shows up in cleaning time every month.
The tradeoff is access. Skirting hides the bolt heads, and owners note that aligning the body over the closet bolts in a tight room can take a couple of attempts. Budget an extra ten minutes and a second set of hands if you have one.
Flush Performance and the 1.28-Gallon Average
Owners report a strong flush even on the 1.1-gallon setting, which is unusual feedback for a compact dual-flush unit. The 1.6 and 1.1 split averages 1.28 gallons, right at the high-efficiency line.
Customer support is a genuine strength here. Multiple reviews mention HOROW replacing parts quickly, which matters more on a model where the tank and bowl are a single ceramic unit and a full replacement is the alternative to a single repair part.
The Seat Shape Takes Some Adjustment
The included polypropylene seat is narrow enough that it can feel like it moves, and its squarer outline is different from the oval seats most people are used to. Owners who switched from a standard toilet commonly describe the first week as odd before settling in.
If the shape bothers you, budget for a different seat. Because the bowl is compact, a full-size aftermarket seat may overhang, so measure the bolt spread and the bowl front before buying a replacement rather than assuming compatibility.
4. DeerValley Compact Dual Flush – Lightest Body for Solo Installations
DeerValley Compact One Piece Toilet Standard Seat Height for Small Bathroom Dual Flush 1.1/1.6 GPF Powerful and Quiet 12” Rough-In Skirted Toilet
24.6"D x 12.99"W x 27.76"H
78 lb ceramic body
28dB soft-close seat
Dual flush 1.1/1.6 GPF
+ Pros
- Compact 24.6-inch depth suits powder rooms
- Light 78-pound body is easy to position
- Quiet refill and strong flush for its size
- Sleek skirted design wipes down easily
- Side-access panels simplify plumbing
– Cons
- Smaller than buyers expect and can look child-sized
- A few users report needing a second flush
- Not a good fit for tall or large users
At 78 pounds, this is the lightest ceramic toilet in the roundup, and that turns out to matter more than any spec sheet in a small bathroom. The AM-1F52812 is the model I suggest to anyone swapping a toilet alone, because getting a 90- to 100-pound one-piece through a door and onto closet bolts by yourself is where installs get abandoned.
It sits at number 3 in the one-piece category on retailer sales rank, which points to steady real-world volume. The 24.6-inch depth pairs with a 12.99-inch width, one of the narrowest bodies here, and the 28dB soft-close seat is one of the quieter setups owners mention.
Why 78 Pounds Changes the Install
Most one-piece toilets in this category land between 86 and 101 pounds. Both the bowl and the tank are one rigid ceramic piece, and once it is over the bolts there is no way to reposition without lifting it back out. At 78 pounds, one person can lift, set, and correct alignment in a single pass.
The installation kit is unusually complete: a pre-assembled valve, wax ring, bolts, wrench and manual, plus side-access panels for servicing. Those panels are what make a skirted body serviceable, and they are usually an add-on on cheaper models.
The 10-Inch Rough-In Variant Is the Real Headline
This model is offered in a 10-inch rough-in version alongside the standard 12-inch. If your existing bathroom has a 10-inch rough-in, that variant is the difference between a straightforward swap and a project involving moving the drain line.
Variants also include black and gold button options and an ADA height version, so the same body can be adapted to different finish schemes and household needs without changing platforms.
The Honest Caveat: It Is Smaller Than You Picture
Several buyers were surprised by how small the toilet looks installed next to a full-size vanity. At 24.6 inches deep and 12.99 inches wide, the footprint is genuinely compact, and the bowl reads smaller than the number suggests.
Owners also note it is not a good match for tall or large users, and a few report needing a second flush. If you are over six feet or want a generous bowl, the elongated options later in this list are the better target.
5. WinZo WZ5079 – Shortest Projection at 22.8 Inches
WinZo Compact One Piece Toilet 22.8″ Depth Modern Short Design Dual Flush for Small Tiny Mini Bathroom 12″ Rough-in,White (WZ5079)
22.8 in projection from wall
3.15 in trapway
Dual flush 0.8/1.6 GPF
16" standard seat height
+ Pros
- Among the shortest profiles at 22.8 inches
- Sleek concealed-trapway styling
- Wide easy-to-press dual flush buttons
- Large trapway with no clogs for most owners
- Fits tiny powder rooms and small campers
– Cons
- Side access ports are too small for easy nut tightening
- Seat can flex and click against the rim
- Some need multiple flushes
- Heavy 98-pound body means two people
When the wall is close and the room is smaller than you want to admit, the WinZo WZ5079 is the shortest honest option in this list. It protrudes 22.8 inches from the wall, which is about three-quarters of an inch shorter than the next closest model here and roughly six to nine inches shorter than a standard elongated toilet.
The styling is deliberately modern, with a concealed trapway and a low-profile tank line that keeps the visual mass down. Owners in tiny powder rooms and small campers consistently prioritise projection depth over every other consideration, and this is the unit that answers that brief.
22.8 Inches of Projection and What It Buys You
In a 3-by-5-foot powder room, the difference between 22.8 inches and 30 inches is roughly seven inches of floor depth recovered. That is enough to place a pedestal sink beside the bowl, swing a door without a clash, or stop the toilet from dominating the room visually.
The trade is bowl size. At 16 inches of standard seat height with a round bowl, this is comfortable for adults but not generous. Larger users generally find it small, and the manufacturer sells the replacement seat separately under a different listing.
A 3.15-Inch Trapway Is the Anti-Clog Argument
Compact does not automatically mean clog-prone, and the double cyclone flush fed by a 3.15-inch trapway is the reason most owners report trouble-free flushing. It is a wider bore than the 2-inch trapways common on other models here.
A minority of owners do report needing multiple flushes and finding residue in the bowl. If you have had chronic low-pressure issues, check the supply line diameter before blaming the toilet, since a kinked flexible connector can starve any model.
Install Ergonomics Are the Trade for the Short Depth
The side access ports are the most common install complaint, because they are too small to comfortably reach the mounting nuts with a wrench. Expect to lift and reset the toilet a few times, which matters a lot at 98 pounds.
The included seat can also flex and click against the rim under weight. Rubber bumpers or an aftermarket seat solves it, and it is the first thing I would change on this unit after installation.
6. DeerValley Chair-Height Compact – Best Budget Buy With a 17-Inch Seat
DeerValley Compact One Piece Toilet for Small Bathrooms with Soft Close Seat 12 Inch Rough Dual Flush 0.8/1.28 GPF Toilets In White
24.6 in projection
Chair-height seat near 17 in
Dual flush 0.8/1.28 GPF
12" rough-in
+ Pros
- Chair-height seating near 17 inches removes the need for a riser
- 24.6-inch projection works in small apartments
- Powerful flush with quick tank refill
- Skirted glazed bowl has few crevices
- Easy DIY installation
– Cons
- Lightweight plastic seat feels cheap and may loosen
- Lid will not stay up on its own
- Seat is not quick-release despite the listing
- A few buyers reported missing parts
The DV-2F52531 is the one to pick if you want a taller seat without spending depth on it. At 24.6 inches of projection with a chair-height seat near 17 inches, it does something most compact models will not do: it stays short while removing the need for a separate riser seat.
The 0.8 and 1.28-gallon dual flush puts the full flush at a genuinely efficient tier, and owners report strong performance with a quick refill. The bowl is fired at 2246 degrees Fahrenheit for stain resistance, and the skirted glaze leaves few crevices to trap dirt.
Chair Height Without the Extra Footprint
Chair height changes sit and stand dramatically for anyone with reduced mobility, and a separate riser seat adds both height and wobble. This model builds the taller seat into the bowl at a footprint of 24.61 by 12.99 inches.
That is the opposite trade from the DeerValley in position two, which is low to the floor. Between the two you can match seat height to the household rather than to the wall clearance, which is the decision most buyers get wrong.
0.8 and 1.28 Gallons: The Best Water Saving Here
The 0.8-gallon partial flush is among the lowest figures in this roundup, and the 1.28-gallon full flush sits right at the high-efficiency tier. If your utility offers a rebate for a high-efficiency toilet, this is one of the few models here that ticks the box on the spec sheet.
Owners report the flush pulling waste without repeat trips, and the refill cycle is fast enough that back-to-back use is not a problem.
Three Seat Problems Worth Knowing Before You Buy
The included plastic seat is the weak point. Owners describe it as feeling cheap, loosening over time, and being the reason they would buy a replacement within a year. Budget for a better seat as part of the install, not as an extra.
Two smaller issues: the lid does not stay up without being held, and the listing describes the seat as quick-release when owners report it must be unscrewed to remove. Some buyers also received incomplete boxes. Check the hardware against the manual before you start.
7. SOTOMO MY-2133 – Best Seat Quality on a Compact Toilet
Compact One Piece Toilet for Bathroom, Space-Saving Powerful Dual Flush Round Small Toilets, Average 1.28 GPF, Skirted Design with Upgraded UF Quiet & Soft Close Seat (12″ Rough-in Toilet)
25"D x 13.4"W x 28.4"H
16.5" seat height
UF soft-close seat
Siphon jet dual flush under 1.28 GPF average
+ Pros
- Upgraded UF seat is heavier and anti-yellowing
- Compact size that still feels comfortable for adults
- Reliable flush with fast refill
- Seamless skirted body wipes clean fast
- Support supplied small replacement parts quickly
– Cons
- Bowl and seat are small for larger users
- A few buyers sourced missing side cover pieces
Seat complaints are the most common thread across every compact toilet review, and this is the model that answers them. The MY-2133 comes with an upgraded UF soft-close quick-release seat instead of the polypropylene seat most competitors include, and owners consistently describe it as noticeably more solid.
That matters over a two to three year cycle. A polypropylene seat flexes, clicks and yellows; UF is denser, scratch-resistant and holds its color. The body itself is 25 inches deep by 13.4 inches wide with a 16.5-inch seat height, which is the same compact footprint as several cheaper models here.
UF Versus Polypropylene: Why the Seat Is Worth Noticing
UF, or unplasticized acrylic, is a harder, denser plastic than the polypropylene used on most budget seats. It resists scratching, does not yellow as quickly, and does not flex enough to click against the bowl rim.
Because the seat is also quick-release, you can pop it off in seconds to clean around the hinges. On a compact toilet where the rim sits close to the wall, that is a small daily convenience that adds up.
A 2-Inch Glazed Trapway at Under 1.28 Gallons Average
The siphon jet dual flush runs 1.6 gallons on full and 1.1 on partial, averaging under 1.28. Owners report no clogs and a fast refill, and the 2-inch fully glazed trapway is standard for this class.
The bowl is fired at 2246 degrees Fahrenheit, which is a stain-resistance treatment rather than a performance feature, but it does help the glaze keep its finish in hard water.
Who Should Skip It
The single repeated caution is size. The bowl and seat are small, and larger users describe the fit as tight. If you are tall or want a generous bowl, look at the elongated models further down instead of trying to get comfortable here.
A few buyers also had to source their own side cover pieces after unpacking, so check the box contents against the manual before you start the install. Ten-inch and twelve-inch rough-in variants are both available.
8. HOROW HR-ST076WD – Elongated Comfort at 28.75 Inches
HOROW HR-ST076WD One Piece Toilet, Dual Flush, Compact Skirted Design
28.75"D x 14"W x 28"H
Elongated bowl
Chair-height seating
Dual flush 1.1/1.6 GPF, MaP 800g
+ Pros
- Elongated bowl and chair height give real comfort
- Concealed skirted trapway cleans easily
- Soft-close seat with stainless steel hinges
- Installation kit includes flush valve and wax ring
- No single defect recurs across reviews
– Cons
- One of the deeper footprints in this roundup at 28.75 inches
- 101-pound body needs two people
- Chair height is too tall for children and shorter adults
This is the comfort-first pick. The HR-ST076WD pairs an elongated bowl with chair-height seating in a body that still measures under 29 inches, which makes it one of the larger models here but the one most adults will find easiest to use.
Where round-bowl compacts get accused of feeling small, this one does not. The 18.5-inch bolt spread and taller seat give a genuinely adult-sized sit, and the concealed skirted trapway keeps the exterior clean without giving up bowl size. It sits at number 26 in its category on retailer sales rank, which points to steady real-world volume.
What a MaP Score of 800g Tells You
MaP, or Maximum Performance, is a gram figure for the heaviest solid waste load a toilet clears in a single flush. This model is rated at 800g, which sits in the range most people would call full performance for a 1.28-gallon average.
In practice it means fewer double flushes on a full load. Owners report clean bowl results with the 1.6-gallon full setting, and the dual flush at 1.1 and 1.6 averages 1.28 gallons.
Where the 28.75 Inches Stop Working
At 28.75 inches this is among the deepest toilets in the roundup, so it needs the most wall clearance. It works in a 5-by-8-foot full bathroom and most 4-by-6-foot rooms, but it is a poor fit for a 3-by-5-foot powder room where every inch counts.
Measure before you commit. If your available projection is under 28 inches, the shorter models earlier in this list will serve you better even if they are less comfortable.
Chair Height Cuts Both Ways
The taller seat is the point for anyone with knee or hip problems, and a 1-year limited warranty with lifetime after-sales service is a reasonable support commitment for the tier.
It also means children and shorter adults will struggle to reach the floor, which is the most repeated complaint about chair-height toilets generally. In a mixed household, the 16.5-inch standard-height models are the safer compromise.
9. WinZo WZ5089 – Best Large Trapway at a 23-Inch Length
WinZo WZ5089 Compact Round One Piece Toilet 23″ Depth,Dual Flush For Small Modern Bathroom 12″ Rough-in White
23" overall length
3.15 in trapway, double cyclone nozzles
Dual flush 0.8/1.6 GPF
Concealed trapway
+ Pros
- Very short 23-inch length for small bathrooms
- Concealed trapway and clean styling
- Large trapway designed to reduce clogs
- Dual flush averages 1.28 GPF
- Side holes and quick-release seat simplify service
– Cons
- Rating spread is wider than similar models
- Higher share of 3-star ratings than most picks
- Some buyers report installation or finish problems
The WZ5089 sits alongside the shorter WinZo as a 23-inch-length option, and it is the one to choose if clog resistance is your priority in an older home with cast iron branches or older drain lines. The 3.15-inch trapway with double cyclone nozzles is genuinely large for a unit this shallow.
It comes with a pre-installed fill and flush valve, and the box includes the wax ring, bolts and side covers. That is a complete package, and the quick-release seat uses stainless steel top-mounted bolts rather than plastic.
Trapway Diameter as a Clog Predictor
A wider trapway moves waste with less resistance, which is why 3.15 inches is a spec worth caring about if your home has narrow or aging drain lines. It is also why compact models with 2-inch trapways can feel more prone to repeat flushes.
Most owners of this model report trouble-free flushing, and the dual flush at 0.8 and 1.6 gallons averages 1.28 for water savings.
Reading the Rating Spread Honestly
This model carries a 4.2 average across 84 reviews, the lowest in the roundup, and a noticeably higher share of 3-star ratings than the models around it. That pattern usually points to a cluster of installation or finish problems rather than a design flaw.
Variants include golden and black button versions and the related WZ5069, so the styling can be matched to an existing bathroom. Check the finish carefully when the unit is unboxed given what the ratings suggest.
Concealed Trapway and the 15-Inch Width
The concealed trapway keeps the sides of the bowl clean and continuous, which suits a small bathroom where the toilet is close to a vanity wall and hard to reach around.
At 15 inches wide this is not the narrowest model here. If side clearance is your binding constraint rather than depth, go back to the 13.1-inch and 13.4-inch options earlier in this list.
10. BAYROLL SH-S001 – Best ADA Compliance and Highest MaP Score
BayRoll One Piece Sleek Modern Toilet, ADA Chair Seat Height 17″, Dual Flush 0.9/1.28 GPF, MAP 1000g, 12″ Rough-In, Compact Fully Skirted Round Toilet for Bathrooms Soft Close Seat
25.6"D x 14.8"W x 27"H
ADA 17" chair-height seat
Dual flush 0.9/1.28 GPF, MaP 1000g
Fully skirted body
+ Pros
- Highest average rating in the roundup at 4.6
- ADA 17-inch chair height eases sitting and standing
- MaP 1000g flush clears about 2.2 lb per flush
- Fully skirted body wipes clean quickly
- Soft-close quick-release seat
– Cons
- Small side access openings frustrate DIY bolt alignment
- Body is wider than standard so check the supply inlet
- Flush button must be pressed fully
This is the accessibility pick. The 17-inch ADA chair-height seat, the generous bowl opening and a 25.6-inch depth make it a sensible target for an aging-in-place retrofit, and at 4.6 it carries the highest average rating of any model here.
It is also the only one in the roundup with a published MaP figure of 1000g, roughly 2.2 pounds of solid waste cleared in a single flush, while using 0.9 or 1.28 gallons. That combination of capacity and efficiency is unusual at this footprint and is why owners report no clogging at all.
MaP 1000g Without Wasting Water
The MaP score and the GPF rating measure different things, and this model performs well on both. A 1000g MaP with a 1.28-gallon full flush and a 0.9-gallon partial means clearing capacity without defaulting to an old 3.5 or 1.6-gallon full tank.
Owners report a strong, efficient flush with no clogging, and the upgraded side water outlet is designed to reduce limescale buildup, which matters in hard-water areas where the flush valve is otherwise the first component to fail.
ADA Height, and the Clearance That Comes With It
ADA and chair-height seating is not a premium feature bolted on later; it is built into the bowl here at 17 inches. For a retrofit where someone is using a walker, that is the difference between an independent bathroom and a supervised one.
The 14.8-inch width is wider than most models in this roundup, so measure side clearance and the position of your supply inlet before ordering. A gold button variant is available if you want to match other bathroom fixtures.
Check the Angle Valve Position Before You Order
This model needs an angle valve more than 8 inches from the waste center, or one that protrudes less than 3 inches. That is a real constraint in older bathrooms where the stop valve sits low or close in.
The other install note is the tight side access openings, which owners say can mean lifting and resetting the toilet a few times to line up the bolts. Plan for a second person, and make sure the flush button is pressed fully to complete a flush.
11. Gerber Viper Force Compact – Best Two-Piece for Serviceable Parts
Gerber Viper Force Compact Elongated Two-Piece Toilet, Soft-Close, White
Compact elongated bowl
1.28 gpf Power Flush
Fluidmaster 400A fill valve, 3" flush valve
ReadySet tool-free seat
+ Pros
- Recognizable major-fixture brand in vitreous china
- Compact elongated bowl gives full-size comfort
- Fast 1.28 GPF flush and quick refill
- Tool-free ReadySet seat removes in seconds
- Higher seat makes sitting and standing easier
– Cons
- Soft-close seat hinge is plastic and can shatter
- Some users report the bowl is not fully clean after every flush
- Two-piece design is bulkier than one-piece options
The Gerber Viper Force is here for a different reason than the rest: parts availability. A two-piece design with a Fluidmaster 400A fill valve and a 3-inch flush valve means when something fails in five years you can buy a valve at a hardware store instead of ordering a specialty part from an overseas manufacturer.
It is also the one model here from a name you will find on plumbing aisle shelves, with vitreous china construction rather than an unbranded ceramic body. That matters in a rental or a home you may sell, because it reads as a fixture rather than an experiment.
Why Two-Piece Can Be the Smarter Small-Space Choice
The instinct in a small bathroom is to choose one-piece, but two-piece has an advantage: the tank is removable. When the bowl is skirted and weighs 80 to 100 pounds, being able to carry the bowl in alone changes the install.
The trade is footprint. At 27.75 inches deep by 16.5 inches wide, this is one of the larger models here, and the tank is a separate visible object. It works in a 5-by-8-foot bathroom rather than a tight powder room.
1.28 GPF Power Flush and Quick Refill
The 1.28-gallon single flush is efficient and the refill is quick, with owners reporting a strong flush. Compact elongated and full elongated variants are both offered, so you can pick the footprint that matches your wall.
The ReadySet soft-close seat removes without tools in seconds, which is genuinely useful for cleaning in a tight room where you would not want to wrestle with mounting bolts.
The Plastic Hinge Is the Weak Point
One owner reports the soft-close hinge shattering when the seat is pushed sideways under lateral force. That is a specific failure rather than a widespread one, but it is worth knowing if you tend to slide the seat rather than lift it.
A few users also report the bowl is not perfectly clean after every flush. The fully skirted one-piece models in this roundup consistently do better on that point, so choose based on how much visible grime bothers you.
12. SUPERFLO CT-1 – Best Corner Toilet for the Tightest Layouts
SUPERFLO 17.2″ Corner Toilet Elongated, Compact Two-piece Toilets
Corner elongated configuration
17.2" comfort height including cover
Dual flush 0.8/1.28 GPF
12" rough-in, siphon flush
+ Pros
- Corner design reclaims floor space in tiny bathrooms
- 17.2-inch comfort height suits a wide range of users
- Dual flush cuts water use at 0.8/1.28 GPF
- 360-degree glazed pipe interior resists residue
– Cons
- 3-star rating cluster is the weakest consistency here
- Bowl and tank are packed in two separate boxes
- Among the tallest units in the roundup at 30.8 inches
Every other model in this roundup pushes straight out from a wall. The SUPERFLO CT-1 turns 90 degrees, putting the tank into the corner so the bowl can angle into the open floor. In a very small room where the drain is already in a corner, that is the only geometry that makes sense.
Owners in tiny half baths single out corner units for exactly this reason. The 17.2-inch comfort height including the cover works for a wide range of adults, and the 0.8 and 1.28-gallon dual flush keeps water use low.
When a Corner Toilet Is the Only Option
A corner configuration is a remodeling decision as much as a purchase. The flange has to be at or near a corner, and the supply has to reach, which means this is rarely a drop-in replacement for a standard wall-mounted toilet in the middle of a wall.
Because the bowl angles diagonally, the listed 32.7-inch depth and 17-inch width describe the bounding box, not the projection into your walking path. That diagonal is the entire point: the usable floor area in front of the bowl is closer to a 23-inch unit’s than a standard toilet’s.
Glazed Siphon Pipe and Water Savings
The siphon flush runs through a 360-degree glazed pipe interior, which resists residue buildup in the trapway. That is a useful feature on a unit people may use less often, like a powder room, where a bowl can sit unflushed for days.
It is a two-piece design with a slow-close seat, and the bowl and the tank are packed in two separate boxes. Some buyers received the second box after the first, so plan the install for when both pieces are in hand.
Where the Feedback Is Thin
This model carries the smallest review base in the roundup at 54 reviews, and roughly 15 percent of those ratings sit at three stars, the weakest consistency among these picks. The sampled review text gives limited detail on what drives those middling scores.
At 30.8 inches tall and a corner footprint, it is also a demanding install in a confined room. If your flange has any flexibility in position, one of the 23- to 25-inch floor models will be a safer purchase.
How to Buy a Compact Toilet Without Getting It Wrong
Every expensive mistake in this category comes down to a measurement taken after the purchase rather than before it. Here is the sequence I use, and the reasoning behind each decision that actually determines whether a compact toilet works in your room.
Measure Your Rough-In and Clearances in 5 Steps
First, measure the rough-in: the distance from the finished wall to the center of the closet bolts or the flange. That number is 10, 12 or 14 inches, and it is the one hard constraint that cannot be worked around without moving the drain line.
Second, measure the total available projection from that finished wall to whatever is in front: a vanity, a wall, a door leaf. Third, measure the clear width on each side of the centerline, remembering that code minimums call for 15 inches to the centerline and 21 inches of clear space in front. Fourth, note whether your angle valve and supply line are more than 8 inches from the waste center and protrude less than 3 inches, which some compact models require. Fifth, check that your doorway will pass the toilet, because a 25-inch-deep one-piece body is still a wide, awkward object on a dolly.
If the old toilet is still installed, you can skip guessing. Measure from the wall to the front of the tank or bowl and add the gap between the tank and bowl to get a true projection figure.
10 Inch Rough-In vs 12 Inch Rough-In: The Mistake That Ruins a Small Bath
Most compact toilets ship as 12-inch rough-in only, which is why buyers with a 10-inch rough-in discover after ordering that the unit will not reach their flange. A 10-inch rough-in wastes two inches of space that a compact model is specifically designed to recover.
Some models here are offered in 10-inch versions, including the DeerValley dual flush in position four, and the HOROW models list a 10-inch rough-in among their available variants. Confirm the rough-in of the exact listing before you buy, because variants often have separate product pages.
Depth, Width and Height: Which Dimension Actually Frees Space
Depth frees the walking path, width frees the side approach, and height frees nothing at all but decides who can use the toilet comfortably. In a rectangular room, depth is usually the binding constraint because it competes with the door swing and the path between the toilet and the vanity.
Height is the dimension people prioritize when they should not. A 17-inch chair-height seat makes the toilet easier to use but does not add a single square inch of floor, and it can make the room feel tighter because the bowl sits visually higher in the space.
Round vs Elongated Bowl: Comfort Against About 2 Inches
Round bowls bolt at 16.5 inches apart, elongated at 18.5. That two-inch difference is usually the entire width story, and it is why round bowls remain the default in powder rooms.
The DeerValley DV-1F52807 shows the exception: an elongated bowl in a 23.5-inch body, which gives you adult comfort without a full-size footprint. If you can find that combination, take it over a round bowl.
One-Piece vs Two-Piece, and Why a Concealed Trapway Matters
One-piece toilets are quieter, lower profile and easier to wipe down, but they weigh 78 to 101 pounds and hide the mounting bolts behind a skirt. Two-piece toilets weigh less, have a removable tank and use standard parts, but the tank is a separate visual block.
In a small bathroom, a concealed or skirted trapway matters more than it does in a large one, because the toilet is close to the vanity and there is little room to reach behind it. Skip in-tank cleaning tablets on any skirted model, since several owners here report flush valve gaskets degrading from them.
Water Use, GPF Tiers and Why Partial Flushes Frustrate People
Gallons per flush is the efficiency tier: 1.6 is the old standard, 1.28 is high efficiency, and 0.8 to 0.9 is a partial flush. Dual-flush models in this roundup average between 1.28 and under 1.28.
The recurring complaint is that partial flushes feel weak. Reviewers consistently report the small button handles liquids fine but leaves some wanting a full 1.28 for solids. If a guest bathroom will be used by people who will not think about which button to press, a single-flush model like the DeerValley 1.28-gallon unit removes the decision entirely.
Seat Height: Standard, Chair Height and Mixed Households
Standard height sits around 15 to 16.5 inches, chair height around 17 inches. Brands name the same thing differently, so compare numbers rather than labels when you are shopping across manufacturers.
The most repeated physical complaint about chair height is feet not reaching the floor, which matters for children and shorter adults. In a mixed household, a standard-height compact model is usually the compromise, or keep a step stool in the room.
Installation Reality: Weight, Hidden Bolts and When to Call a Plumber
A one-piece compact toilet is a two-person job in a tight room. Anything above about 90 pounds, plus a skirted base with hidden bolts, means lifting, aligning and tightening in a confined space.
Call a licensed plumber if your flange is loose or below floor level, if the supply line has to be moved to reach the inlet, if you are on a 10-inch rough-in with only 12-inch models available, or if a wall-hung carrier would need to be framed into an existing wall. If you are comfortable with a wax ring, a level and a wrench, a straightforward 12-inch rough-in floor swap is well within reach of a competent homeowner.
What You Can and Cannot Change in a Condo or Rental
In a rental, you can usually replace the toilet with one that matches the existing rough-in and footprint without altering plumbing, as long as you restore the original fixture on move-out. A wall-hung unit is effectively out, because it requires opening the wall.
In a condo, the drain line is almost always in a concrete slab and moving it is a major structural and financial decision. That makes a short-projection floor model the realistic option, and it is worth confirming whether the association has any fixture approval requirements before you buy.

Frequently Asked Questions
What type of toilet is best for a small bathroom?
A short-projection one-piece toilet measuring 24 to 28 inches from the wall, with a round bowl and a concealed or skirted trapway, is the best type for a small bathroom. It recovers 4 to 8 inches of floor depth versus a standard elongated unit while staying a conventional floor-mounted design you can install without opening a wall. A wall-hung toilet frees even more space but requires an in-wall carrier and a flush plate.
What size toilet is best for a small bathroom?
Aim for a total depth of 24 to 28 inches from the finished wall to the front of the bowl, with a round bowl for a 16.5-inch bolt spread. Models at 23 to 25 inches deep suit 3-by-5-foot powder rooms, while 27 to 28 inch units work in 5-by-8-foot bathrooms. Always confirm your rough-in is 10 or 12 inches before ordering.
What toilet do most plumbers recommend?
Plumbers generally recommend a two-piece floor model with standard parts, a 1.28-gallon single flush and a chair or standard seat height matched to the household, because it is serviceable and cheap to repair. For small rooms, they prioritize correct rough-in and depth over any brand. Wall-hung models are recommended only when the wall is already open.
What are the downsides of a wall-hung toilet?
The downsides are cost, installation complexity and repair risk. A wall-hung toilet needs an in-wall carrier and a separate flush plate, so the opening-wall work and carrier unit add substantially to the total. If the carrier or flush valve fails later, a plumber must open the wall again. Bowl capacity and seat comfort are also smaller than on a floor model.
How far off the wall do you rough in a toilet?
Measure from the finished wall to the center of the closet bolts or the flange, not to the edge of the flange. Standard rough-ins are 10, 12 and 14 inches, with 12 inches by far the most common. A 10-inch rough-in is a problem in a small bathroom because most compact toilets ship as 12-inch models only, so confirm the rough-in before you order.
Which Compact Toilet Should You Buy?
If you want one answer, take the HOROW HWMT-8733. Its 25-inch depth, 13.4-inch width and 16.5-inch seat height cover the most bathrooms without a remodel, and at 694 owner reviews it is the most proven unit in this group. Budget for a better seat, which is the one part most owners upgrade.
If you want an elongated bowl in a very short body, the DeerValley DV-1F52807 at 23.5 inches deep is the pick. If the wall is the constraint and every inch counts, the WinZo WZ5079 at 22.8 inches of projection goes even shorter. If you are installing alone, the 78-pound DeerValley dual flush is the one you can actually lift into place.
If a taller seat is the priority for accessibility, take the BAYROLL SH-S001 with its 17-inch ADA chair height, or the DeerValley in position six for a lower-cost chair-height option. If cleanability matters most in a tight room, the HOROW HT1000 skirted body wipes down fastest, and the SOTOMO MY-2133 is the one whose seat will still feel solid in three years.
Measure your rough-in before anything else, because that single number decides which of these you can install at all. Then check the depth against your wall, and use the buttons on each review to compare current listings for the models that fit.
