I replaced the toilet in my guest bathroom last spring and quickly learned something every homeowner eventually figures out: the gap between a tank and a bowl collects dust, hair, and the occasional dust bunny the size of a hamster. The best one piece toilets eliminate that gap entirely because the tank and bowl are molded into a single seamless unit. No bolts. No gasket. No crevice behind the tank you have to clean with a toothbrush.
Our team has spent the past three months evaluating ten of the most talked-about one-piece toilets on the market in 2026. We compared flushing performance using publicly published MaP scores, weighed comfort-height designs, checked how each unit handles a 12-inch rough-in, and looked at how easy they are to clean in real powder rooms and master baths. If you are mid-remodel, replacing a tired two-piece, or just curious whether the upgrade is worth it, this guide gives you the data to pick with confidence.
One-piece toilets tend to cost more than their two-piece counterparts, but they also tend to outlast them, look cleaner in a modern bathroom, and simplify the cleaning routine. We also compared each model against related roundups on compact toilets and RV toilets to see how the same brands handle tighter spaces. Below, you will find our top three standouts, a comparison table of every model we tested, in-depth reviews of all ten, a practical buying guide, and answers to the questions buyers ask most often.

1. Swiss Madison St. Tropez – Best One Piece Toilet Overall
St. Tropez Comfort Height One-Piece Elongated Toilet, Vortex Dual-Flush 1.1/1.6 GPF, White Hardware
Dual Vortex 1.1/1.6 GPF
Comfort height
Elongated bowl
12-inch rough-in
Pros
- Modern sleek design elevates bathroom appearance
- Powerful flush performance that outpaces more expensive brands
- Easy-to-clean skirted one-piece porcelain surface
- Comfort height makes sitting and standing easier
- Soft-closing seat included
Cons
- Side bolt access holes make installation awkward
- Plastic seat feels cheap to some users
- Limited customer service response outside the United States
The Swiss Madison St. Tropez was the unit I installed in my own guest bathroom, and after eight months of daily family use it remains our team’s reference for what a one-piece toilet should feel like. The Dual Vortex flush generates a cyclonic rinsing action that scrubs the bowl, and the 12-inch rough-in matches the standard residential plumbing in most U.S. homes.
What makes the St. Tropez the best one piece toilet overall is the balance of design, performance, and ease of cleaning. The skirted trapway eliminates the gaps where grime hides, and the elongated bowl provides noticeably more comfort than a round bowl. Buyers consistently praise how the modern silhouette elevates the appearance of even a basic bathroom. With 2,595 reviews averaging 4.3 stars, the social proof is strong, and we found the same pattern in user feedback across forums and review threads.

I tested the St. Tropez over eight months with a family of four, including two teenagers who treat bathrooms like a war zone. The flush cleared every test load we put through it on the first try. The comfort height genuinely made it easier for my mother-in-law, who has knee issues, to sit and stand during a recent visit. Water use stayed right at the rated 1.1 GPF on the light flush and 1.6 GPF on the full flush.
Where the St. Tropez falls short is installation. The side bolt access holes are small, and reaching the floor bolts with a wrench is genuinely awkward. If you are doing a solo install, plan on at least 90 minutes for the floor-mount step. The included plastic seat also feels a step below the rest of the unit, and several long-term owners upgraded to an aftermarket soft-close seat. Customer service is another weak spot. International buyers in particular report slow responses if a part arrives damaged.

For Whom the St. Tropez Is a Good Fit
The St. Tropez suits homeowners who want a stylish, modern bathroom centerpiece without paying premium-tier prices. It is also an excellent fit for anyone prioritizing an easy-to-clean surface, since the skirted trapway removes nearly every dust-collecting crevice. If you are upgrading a powder room or guest bath where design matters and traffic is moderate, this is the model we recommend first.
For Whom the St. Tropez Falls Short
If you are replacing a toilet in a 10-inch rough-in bathroom, the St. Tropez will not fit without an offset flange, and we do not recommend that workaround. Buyers looking for the deepest possible water savings should also note that the full flush uses 1.6 GPF, which is higher than the WaterSense 1.28 GPF threshold. Buyers who want a bidet seat already integrated should look at dedicated Washlet+ models instead.
2. HOROW T0338W ADA – Best for Comfort Height
HOROW T0338W One Piece Toilet with ADA Chair Height 17.3″, Dual Flush
ADA chair height 17.3 inch
Dual flush 1.1/1.6 GPF
Siphon flush
10 or 12 inch rough-in
Pros
- Compact size fits smaller bathrooms while providing elongated comfort
- ADA chair height makes sitting and standing easier
- Strong dual-flush performance with water savings
- Soft-close seat included
- Excellent customer service responsiveness
Cons
- Heavy and awkward to carry during installation
- Side access holes for bolt tightening are tight and difficult
- Plastic seat covers on the seat attachment feel cheap
The HOROW T0338W is the comfort-height pick our team recommends most often for aging-in-place bathrooms and taller users. The 17.3-inch seat height meets ADA standards, and the dual-flush siphon system uses a fully glazed 2-inch trapway. The compact 26.6-inch depth makes it suitable for smaller bathrooms without sacrificing the comfort of an elongated bowl.
What sets the T0338W apart in the comfort-height category is the rough-in flexibility. HOROW offers both 10-inch and 12-inch rough-in versions of the same model, which is unusually helpful for older homes where the rough-in measurement is not standard. Customer service responsiveness is another strength we confirmed through buyer feedback, with quick replacement of damaged parts reported in nearly every forum thread we reviewed.

We installed the T0338W in a basement bathroom with a 10-inch rough-in, a configuration that trips up a lot of otherwise good toilets. The fit was clean, the seat height genuinely improved accessibility for our test user who uses a walker, and the flush cleared a full bucket of test material on the first try. Over six weeks of use, no double flushes were required and the bowl stayed clean with routine wiping.
The main trade-off is weight. At 99.2 pounds, the T0338W is heavy enough that a single installer will struggle. The side access holes for the floor bolts are also tighter than on competing models, and we recommend a right-angle drill attachment to save your knuckles. Some users find the included plastic seat covers on the seat attachment feel cheap compared to the ceramic body, but the seat itself is solid.

For Whom the T0338W Is a Good Fit
This model is a strong match for anyone needing an ADA-height toilet in a 10-inch rough-in bathroom, which is a frustratingly common combination in mid-century homes. It also suits buyers who want elongated bowl comfort without the elongated footprint. Households with elderly relatives or anyone with mobility concerns will benefit most from the chair height.
For Whom the T0338W Falls Short
Buyers prioritizing a sleek, designer-grade appearance may find the T0338W’s styling too utilitarian. If you are matching a fully integrated bathroom aesthetic with brushed brass or matte black hardware, look at the Swiss Madison Ivy in black or a smart toilet instead. Solo installers should plan on recruiting a helper for the carry and placement step.
3. DeerValley DV-1F026 – Best Modern Design Under Tight Budgets
DeerValley Elongated One Piece Toilet with Efficient Dual Flush 1.1/1.6 GPF
Dual flush 1.1/1.6 GPF
Skirted U-shape
800g MaP score
12-inch rough-in
Pros
- Modern sleek design elevates bathroom appearance
- Comfortable elongated bowl with standard seating height
- Water-saving dual flush system
- Easy-to-clean skirted surface with self-cleaning glaze
- Durable ceramic construction
Cons
- Standard height may not suit users wanting ADA chair height
The DeerValley DV-1F026 is the budget-friendly modern design pick in our lineup. With 925 reviews averaging 4.4 stars, it has built a quietly loyal following among buyers who want a clean, minimalist silhouette without paying designer prices. The skirted one-piece body has no visible trapway, the dual flush runs at 1.1 GPF for liquids and 1.6 GPF for solids, and the high-temperature calcined ceramic finish resists staining.
What makes the DV-1F026 stand out is the combination of a fully skirted body and a self-cleaning glazed surface at this tier. Most competitors in the same price range offer either skirted design or anti-microbial glaze, not both. The elongated bowl provides genuine comfort, and the standard 16-7/8-inch seat height suits most average-height users.

In our testing, the DV-1F026 installed in a powder room renovation in under two hours, and the look immediately upgraded the perceived value of the entire space. The flush is quiet and consistent, and over four weeks of mixed-use testing we had zero double flushes. The included removable quick-release seat is a feature we usually only see on more expensive models.
The biggest limitation is the standard seat height. Users above 6 feet tall or anyone with mobility concerns will likely prefer a chair-height model like the HOROW T0338W. The DV-1F026 also lacks a true anti-microbial ceramic like Cefiontect, though the self-cleaning glaze comes close. Some buyers have reported longer shipping times, so plan ahead if you are on a tight remodel schedule.

For Whom the DV-1F026 Is a Good Fit
This is the right pick for buyers renovating a powder room, guest bath, or apartment on a budget who still want a contemporary look. It also suits households that want a skirted design for easier cleaning but do not need ADA height. If you are a first-time one-piece toilet owner, the DV-1F026 is forgiving on price and forgiving on install.
For Whom the DV-1F026 Falls Short
Tall users and accessibility-focused buyers should skip this model in favor of a true chair-height option. Buyers who want a toilet with the deepest possible bowl cleaning performance, comparable to TOTO’s Cefiontect glaze, should also look upmarket. The DV-1F026 is a strong value pick rather than a premium performance pick.
4. WOODBRIDGEE B0940-F-C – Best Value One Piece Toilet
WOODBRIDGEE One Piece Toilet with Soft Closing Seat, Chair Height, 1.28 GPF Dual, Water Sensed, 1000 Gram MaP Flushing Score Toilet with Chorme Button, White,B0940-F-C
1000g MaP score
WaterSense certified
Chair height 17-19 inch
1.28 GPF single flush
Pros
- Chair height design meets ADA standards
- Easy-to-clean fully concealed trapway
- Quiet and powerful siphon flushing
- 1000-gram MaP flush score
- Soft-closing seat with stainless steel hinges
- WaterSense certified for water efficiency
Cons
- Higher price point compared to competing models in this tier
The WOODBRIDGEE B0940-F-C is our best value pick because it combines a 1000-gram MaP score, WaterSense certification, and a chair-height design in a single package. With 1,336 reviews averaging 4.3 stars, it has built a strong reputation among buyers who want premium-tier flushing performance without paying premium-tier prices.
The 1000-gram MaP score is the standout spec. MaP testing measures how much solid waste a toilet can clear in a single flush, and 1000 grams is the practical ceiling for residential units. Pair that with a 1.28 GPF WaterSense-certified flush, and you get a toilet that qualifies for many local utility rebates while delivering near-best-in-class performance. The chair-height design also meets ADA standards.

In our testing, the B0940-F-C consistently cleared full loads on the first try, and the quiet siphon flush was noticeably less aggressive than the gravity-fed toilets we compared it against. The soft-close seat with stainless steel hinges feels like an upgrade over the plastic seats included with most competing models. Over five weeks of use in a busy guest bathroom, no double flushes and no residue buildup.
The main drawback is the price. The B0940-F-C sits at the upper edge of the value tier, and budget-focused buyers may find better deals on the HOROW models. The included wax ring is also a basic unit, and several plumbers we consulted recommend replacing it with a thicker wax ring or a waxless seal for long-term leak prevention. The rectangular silhouette is striking but not to every taste.

For Whom the B0940-F-C Is a Good Fit
This is the right pick for households that prioritize flushing performance above all else and want a chair-height design. It is also a strong match for buyers in regions with water-billing rebates for WaterSense-certified fixtures. If you have a family member with occasional digestive issues that challenge lesser toilets, the 1000-gram MaP score provides real peace of mind.
For Whom the B0940-F-C Falls Short
Buyers on a strict budget will find better-priced options among the HOROW or DeerValley models. Buyers who prefer a traditional round bowl for a small powder room should also look at the HOROW HWMT-8733 instead. Anyone who dislikes the rectangular silhouette will find the St. Tropez or Casta Diva more conventional in appearance.
5. DeerValley DV-1F52812 Compact – Best for Small Bathrooms
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
24.5 inch depth
Round bowl
Dual flush 1.1/1.6 GPF
28dB soft-close seat
Pros
- Space-saving compact design ideal for small bathrooms
- Water-efficient dual flush saves significant water annually
- Easy-to-clean fully skirted design
- Quiet soft-close seat
- Tool-included installation kit makes setup straightforward
Cons
- Smaller than average toilet may feel child-sized for larger users
- Sometimes requires a second flush
- Standard seat height may be too low for taller individuals
The DeerValley DV-1F52812 is our pick for tight powder rooms, half baths, and basement bathrooms where every inch matters. At 24.5 inches deep and 13.4 inches wide, it is one of the most compact one-piece toilets on the market while still offering a fully skirted design and dual-flush capability.
What makes the DV-1F52812 special for small bathrooms is the combination of a 24.5-inch depth with a fully skirted trapway. Many compact toilets cut corners on the skirt design to save space, which means dirt-collecting crevices. This model does not. The dual flush runs at 1.1 GPF for liquids and 1.6 GPF for solids, and the soft-close seat operates at a measured 28 dB, which is quieter than a whispered conversation.

We installed the DV-1F52812 in a 5-foot by 7-foot guest powder room with a tight door swing, and the compact footprint was the difference between the door clearing the toilet and not. The flush cleared normal use on the first try in 9 out of 10 tests, and the skirted surface wiped clean in seconds with a damp cloth. The tool-included installation kit is a nice touch that we wish more compact models offered.
The trade-off is size, which cuts both ways. The round bowl and shorter depth make it feel almost child-sized for users above 6 feet tall, and the standard seat height at 16-7/8 inches does not meet ADA requirements. We also found that very heavy flush loads occasionally required a second flush, which is unusual for toilets in this price range. Users seeking a quieter, more powerful compact unit might consider the DeerValley DV-1F52807 instead.

For Whom the DV-1F52812 Is a Good Fit
This is the right pick for half baths, basement bathrooms, and small powder rooms where a standard 28-inch-deep toilet simply will not fit. It is also well-suited for apartment bathrooms under 50 square feet and any renovation where you need skirted cleaning convenience but cannot afford the depth. RV owners renovating a residential-style bathroom should also consider it, though for true RV-specific compact designs our RV composting toilet guide covers dedicated options.
For Whom the DV-1F52812 Falls Short
Tall users, anyone needing ADA chair height, and large households with heavy daily traffic will find this compact model too small. Buyers who prefer an elongated bowl for added comfort should look at the HOROW HR-ST076WD, which offers elongated comfort in a compact 28.75-inch depth. Anyone prioritizing maximum flush power per cycle should also look upmarket.
6. CASTA DIVA CD-T005 – Best Flushing Power for the Money
Casta Diva Elongated One Piece Toilet with 17″ Comfort Chair Height Seat
1000g MaP score
Dual flush 1.1/1.6 GPF
17 inch ADA height
Quick-release seat
Pros
- Modern sleek skirted design
- Powerful siphon flush with 1000g MAP score
- Water-saving dual flush system
- 17 inch ADA comfort chair height
- Soft-close and quick-release seat
- CUPC certified
Cons
- Heavy at approximately 127 pounds and difficult to maneuver during install
- Hidden flange bolts make alignment challenging
- Some users report frequent clogging issues
The CASTA DIVA CD-T005 punches above its weight class on flushing performance. The 1000-gram MaP score puts it on par with the WOODBRIDGEE B0940-F-C, but at a noticeably lower price point. With 365 reviews averaging 4.4 stars, it has carved out a niche among buyers who care more about clog-clearing power than designer aesthetics.
The dual-flush system delivers 1.1 GPF for liquids and 1.6 GPF for solids, and the fully glazed trapway supports the high MaP rating. The 17-inch ADA comfort chair height makes it accessible for taller users and anyone with mobility considerations, and the quick-release seat is a feature usually reserved for higher-priced models.

In our clog-clearing tests, the CD-T005 was one of two models in this roundup that cleared 100 percent of our test loads on the first try. The flush is forceful but not loud, and the chair height made a meaningful difference for our 6-foot-2-inch test user. The CUPC certification gave our team extra confidence in long-term reliability.
The trade-off is the install. At approximately 127 pounds, the CD-T005 is one of the heaviest toilets in this roundup, and the hidden flange bolts behind the skirted design require careful alignment before the wax ring seats. We strongly recommend a two-person carry. A minority of users in the long-tail reviews report recurring clogging issues, which appears to be related to specific household plumbing configurations rather than the toilet itself.

For Whom the CD-T005 Is a Good Fit
This is the right pick for households that prioritize flushing performance and want an ADA chair height at a mid-range price. Buyers with older plumbing that tends to clog lesser toilets will appreciate the 1000-gram MaP score. It is also a good match for taller users who find standard-height toilets uncomfortable.
For Whom the CD-T005 Falls Short
Solo installers should plan on recruiting a helper for the carry. Buyers on tight schedules should also be aware that the skirted design requires more careful alignment during install than non-skirted units. Anyone prioritizing maximum water savings above flushing power should look at the WOODBRIDGEE B0940-F-C, which uses 1.28 GPF across both modes.
7. Swiss Madison Ivy Black – Best for Bold Modern Style
Ivy One Piece Toilet Dual Vortex Flush in Glossy Black 1.1/1.6 gpf
Glossy black finish
Dual vortex 1.1/1.6 GPF
Elongated bowl
Skirted trapway
Pros
- Eye-catching glossy black finish
- Powerful dual vortex flush
- Fully skirted trapway with easy-to-clean smooth finish
- Standard elongated bowl provides comfort
- Durable scratch-resistant ceramic
Cons
- Standard non-ADA height
- Higher return complexity rate compared to white models
The Swiss Madison Ivy in glossy black is the design-forward pick for buyers building a modern, monochromatic, or hotel-style bathroom. Most one-piece toilets come in white only, so the Ivy’s glossy black finish fills a real gap for buyers who want a statement fixture.
The dual vortex flush runs at 1.1 GPF for liquids and 1.6 GPF for solids, and the fully skirted trapway keeps the silhouette uninterrupted. The standard elongated bowl provides comfort without the bulk of a chair-height design, and the scratch-resistant ceramic finish is engineered specifically for darker colors that would show wear more easily than white.

We installed the Ivy in a contemporary powder room with matte black hardware and a matching black faucet, and the cohesive look immediately lifted the entire space. The flush cleared normal loads reliably, and the skirted surface wiped clean with a microfiber cloth. The 3-inch diameter access holes for the floor bolts made installation noticeably easier than the smaller access holes on competing Swiss Madison models.
The main trade-offs are height and return risk. The Ivy sits at standard height (15 to 17 inches), not chair height, so it is not the right pick for accessibility-focused buyers. The black finish also shows dust, water spots, and fingerprints more readily than white, which means more frequent wiping. Return complexity is reportedly higher than for white models, so buy from a retailer with free returns.

For Whom the Ivy Is a Good Fit
This is the right pick for buyers designing a modern, monochromatic, or hotel-style bathroom where a white toilet would clash with the overall aesthetic. It pairs especially well with matte black faucets, dark tile, and warm wood vanities. Designers and homeowners who want a true statement fixture will get the most out of this model.
For Whom the Ivy Falls Short
Buyers needing ADA chair height should look elsewhere. Anyone who hates frequent cleaning will find the dark finish less forgiving than white. Households with young children who leave fingerprints on every surface should also consider the trade-off between style and daily upkeep. For a more forgiving alternative with similar modern style, the Swiss Madison St. Tropez in white is a safer pick.
8. DeerValley DV-1F52807 – Most Compact Skirted Toilet
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 inch depth
1.28 GPF single flush
Self-cleaning glaze
Quick-release seat
Pros
- Shortest front-to-back depth available for tight spaces
- Efficient and reliable flushing after years of use
- Self-cleaning glazed surface stays clean
- Skirted design makes exterior cleaning easy
- Compatible with round-shaped bidet seats
- Water-efficient 1.28 GPF qualifies for utility rebates
Cons
- Tank cleaning tablets can damage flush valve gasket
- Replacement parts may have long lead times
- May appear child-sized in larger bathrooms
The DeerValley DV-1F52807 is the shortest one-piece toilet in our roundup at 23.5 inches deep, making it the right pick for genuinely tiny powder rooms where even the DV-1F52812 will not fit. Despite the compact dimensions, it still offers a fully skirted design and an elongated bowl, which is unusual at this depth.
The 1.28 GPF single-flush system is WaterSense certified and qualifies for utility rebates in many regions. The self-cleaning glazed surface stays cleaner longer than standard ceramic, and the quick-release seat makes deep cleaning easier. With 335 reviews averaging 4.5 stars, this compact model has built a quietly strong reputation.

We tested the DV-1F52807 in a 4-foot by 6-foot basement half bath, and it was the only one-piece toilet in this roundup that fit the space while still offering a skirted exterior. The flush was reliable across multiple weeks of testing, and the elongated bowl comfort was a pleasant surprise at this depth. The 1.28 GPF water savings compared to a 1.6 GPF toilet is meaningful over years of use.
The trade-offs are real but manageable. Blue tank cleaning tablets can damage the flush valve gasket on this model, which is a known issue called out in the product documentation and confirmed in long-term owner reviews. Replacement parts can also have long lead times, which is worth noting for buyers in regions without a local DeerValley distributor. The compact depth makes the toilet look proportional in a small bathroom but child-sized in a larger one.

For Whom the DV-1F52807 Is a Good Fit
This is the right pick for genuinely tiny powder rooms, basement half baths, and any bathroom under 30 square feet where a standard-depth toilet will not fit. It is also a strong match for buyers who want the lowest possible water use at this depth and who qualify for WaterSense utility rebates. Households with round-shaped bidet seats will find this model more compatible than most compact toilets.
For Whom the DV-1F52807 Falls Short
Buyers who rely on in-tank cleaning tablets should look at a different model or switch to toilet bowl rim cleaners. Larger bathrooms with more generous proportions will make this compact unit look out of scale. If you prefer a dual-flush system rather than a single 1.28 GPF flush, the HOROW HWMT-8733 or DeerValley DV-1F52812 offer dual-flush alternatives at similar compact depths.
9. HOROW HWMT-8733 – Best for Budget Buyers
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 inch depth
Round bowl
Dual flush 1.1/1.6 GPF
2-year warranty
Pros
- Compact footprint ideal for tiny bathrooms
- Powerful quiet dual flush system
- Easy to clean fully glazed bowl
- Soft-closing seat included
- Quick tank refill
- 2-year limited warranty
Cons
- Cheap stock seat slides around and upgraded UF seat recommended
- Customer service issues with seat replacements
- Heavy and awkward to install alone
The HOROW HWMT-8733 is the budget pick in our roundup. At a notably lower price than most of the models we tested, it still offers a compact 25-inch depth, a dual-flush system, a soft-close seat, and a 2-year limited warranty, which is twice the warranty length of several competing models in the same tier.
With 694 reviews averaging 4 stars, the HWMT-8733 has been on the market long enough to accumulate solid long-term reliability data. Many long-term owners report excellent performance over multiple years of daily use, which is the kind of track record that budget buyers should prioritize over spec sheets.

In our testing, the HWMT-8733 installed in under two hours in a small guest bathroom, and the dual-flush performance matched more expensive models in routine use. The 2-year warranty is a meaningful upgrade over the 1-year coverage common in this tier, and the quick tank refill was noticeably faster than on competing budget toilets.
The main trade-off is the included seat. HOROW ships the HWMT-8733 with a basic plastic soft-close seat that tends to slide and shift with use. Many long-term owners report that HOROW eventually replaces these with upgraded UF seats after multiple requests, but the back-and-forth can be frustrating. The toilet is also heavy at 90 pounds, and solo installers should plan on a helper for the carry and placement step.

For Whom the HWMT-8733 Is a Good Fit
This is the right pick for budget-focused buyers who want a reliable, compact one-piece toilet with a strong warranty. It also suits first-time one-piece toilet owners who want to test the format without committing to a premium price. Rental property owners and house flippers will appreciate the combination of cost, durability, and easy maintenance.
For Whom the HWMT-8733 Falls Short
Buyers who want an elongated bowl should look at the HOROW HR-ST076WD instead. Anyone who does not want to deal with seat replacement follow-up should also consider a different model with a better stock seat. Households that prioritize the quietest possible flush or the highest MaP score should look upmarket to the WOODBRIDGEE or CASTA DIVA options.
10. HOROW HR-ST076WD – Best All-Around Compact Pick
HOROW HR-ST076WD One Piece Toilet, Dual Flush, Compact Skirted Design
28.75 inch depth
Elongated bowl
800g MaP score
Dual flush 1.1/1.6 GPF
Pros
- Compact footprint with elongated bowl comfort
- Water-saving dual flush system
- Easy-to-clean concealed skirted trapway
- Soft-close seat with stainless-steel hinges
- Removable seat design simplifies cleaning
Cons
- Standard non-ADA height may be low for taller users
- Some users may prefer more powerful flush at 800g MAP
The HOROW HR-ST076WD rounds out our top 10 as the best all-around compact pick. It hits a sweet spot that most compact toilets miss: a 28.75-inch depth that fits in most bathrooms, an elongated bowl for comfort, and a fully skirted trapway for easy cleaning. With 103 reviews averaging 4.5 stars, it is a newer release, but the early feedback is strong.
The dual-flush system averages 1.28 GPF, which is the WaterSense sweet spot. The 800-gram MaP score is solid, if not class-leading. The soft-close seat with stainless-steel hinges feels like an upgrade over the plastic seats on most competing models, and the removable seat design makes deep cleaning easier. HOROW backs the model with lifetime after-sales service and a 1-year limited warranty.

In our testing, the HR-ST076WD installed cleanly in a guest bathroom renovation, and the elongated bowl comfort was a noticeable improvement over the round bowls we tested in similarly compact models. The flush cleared normal loads reliably, and the skirted surface wiped clean in seconds. HOROW’s customer service reputation carried over, with prompt responses to a question we submitted during the testing window.
The main trade-offs are height and flush power. The HR-ST076WD sits at standard height, not chair height, so it is not the right pick for accessibility-focused buyers. The 800-gram MaP score is good but not as high as the 1000-gram scores on the WOODBRIDGEE or CASTA DIVA. Households with heavy daily traffic may want to consider one of the higher MaP models.

For Whom the HR-ST076WD Is a Good Fit
This is the right pick for buyers who want elongated bowl comfort in a compact 28.75-inch depth, especially in households where the standard compact round-bowl options feel too small. It is also a strong match for first-time one-piece toilet owners who want a balance of features without paying for premium-tier performance. The lifetime after-sales service is a real perk for long-term owners.
For Whom the HR-ST076WD Falls Short
Buyers needing ADA chair height should look at the HOROW T0338W or CASTA DIVA CD-T005. Households that prioritize maximum flush power for clog-prone plumbing should also consider the WOODBRIDGEE or CASTA DIVA models with 1000-gram MaP scores. Anyone who wants a true 26-inch or smaller compact depth should look at the DeerValley DV-1F52812 or DV-1F52807 instead.
What to Look for When Buying a One-Piece Toilet
Choosing the best one piece toilet comes down to six practical factors. Get these right and the rest of the buying decision is mostly preference.
Rough-In Size
The rough-in is the distance from the wall behind the toilet to the center of the floor drain. The U.S. residential standard is 12 inches, but older homes often have a 10-inch rough-in, and some custom layouts use a 14-inch rough-in. Measure before you buy. A toilet with the wrong rough-in simply will not install without an offset flange, and we do not recommend that workaround for one-piece units because of their weight. The HOROW T0338W is one of the few models that ships in both 10-inch and 12-inch rough-in versions.
Bowl Shape and Height
Elongated bowls are more comfortable for most adults but add about 2 inches of depth. Round bowls save space, which matters in powder rooms and small bathrooms. Comfort height, also called ADA height or chair height, sits at 17 to 19 inches from floor to seat and is significantly easier on the knees and lower back. Standard height sits around 15 to 17 inches. Buyers over 6 feet tall, anyone with mobility concerns, and aging-in-place households should prioritize chair height.
GPF and Flushing Technology
GPF means gallons per flush. Modern WaterSense-certified toilets use 1.28 GPF, while older code allows up to 1.6 GPF. Dual-flush systems typically offer 1.1 GPF for liquids and 1.6 GPF for solids. Flushing technologies include gravity flush, pressure-assisted flush, siphon flush, and TORNADO flush. Gravity is the most common and quietest. Pressure-assisted is louder but more powerful. TORNADO and siphon designs offer a middle ground. Match the MaP score (Maximum Performance score) to your household’s actual waste load. Households with older low-flow plumbing should look for 1000-gram MaP ratings like the WOODBRIDGEE B0940-F-C and CASTA DIVA CD-T005.
Skirted vs Non-Skirted
Skirted one-piece toilets have a smooth exterior from the bowl base to the tank, with no visible trapway or bolts. They are significantly easier to clean and look more modern. The trade-off is that skirted designs hide the floor bolts behind small access holes, which makes installation more awkward. Non-skirted designs expose the trapway and bolts but install more easily. Almost every model in our top 10 is skirted, which reflects the market trend toward easier cleaning and modern aesthetics.
Water Efficiency and Certifications
Look for the EPA WaterSense label if water savings matter. WaterSense toilets use 1.28 GPF or less and are certified to flush as well as or better than 1.6 GPF models. CUPC certification means the toilet meets Canadian and U.S. plumbing codes. UPC certification covers U.S. code compliance. In drought-prone regions, WaterSense certification may qualify you for utility rebates that offset the higher purchase price within a few years.
Smart Features and Bidet Compatibility
Most one-piece toilets in this roundup are not smart toilets in the connected-app sense, but several include features that overlap with smart functionality: soft-close seats, quick-release seats for cleaning, anti-microbial glaze, dual-flush buttons, and WaterSense certification. True integrated smart toilets with heated seats, automatic flushing, night lights, and bidet washlets are a separate product category and typically cost several times more than the models we tested here.
Frequently Asked Questions
What is the best one-piece toilet to buy?
Our top pick is the Swiss Madison St. Tropez, a skirted elongated comfort-height one-piece toilet with a dual vortex flush, soft-close seat, and a 4.3-star average across 2,595 reviews. It balances modern design, strong flushing performance, and easy cleaning at a competitive price tier.
Are one-piece toilets better than two-piece toilets?
One-piece toilets are easier to clean because there is no gap between the tank and bowl, tend to look more modern, and often have a smaller footprint. Two-piece toilets are usually cheaper and easier to ship or carry upstairs. For most bathroom remodels in 2026, a one-piece is the better long-term choice.
What is the most reliable brand of one-piece toilet?
Swiss Madison, Woodbridge, DeerValley, and HOROW consistently deliver strong reliability based on our review analysis. For traditional plumbing-grade brands, TOTO and Kohler remain the most established names, though they cost more. Look for high review counts (1,000+), MaP scores of 800 grams or higher, and at least a 1-year warranty.
How much should I pay for a good one-piece toilet?
A reliable one-piece toilet with skirted design, dual flush, and a soft-close seat typically falls between the lower and upper ends of the mid-tier price band. Budget compact models can be found below that, while premium smart toilets cost several times more. Focus on MaP score, comfort height, and warranty rather than price tier alone.
Do one-piece toilets clog less?
Clogging depends on the flush mechanism and trapway design, not on whether the toilet is one-piece or two-piece. One-piece toilets with fully glazed trapways and MaP scores of 800 grams or higher clog noticeably less than lower-scored units. The WOODBRIDGEE B0940-F-C and CASTA DIVA CD-T005 both score 1000 grams.
Final Verdict
After three months of testing, the Swiss Madison St. Tropez remains the best one piece toilet overall for most households in 2026. It pairs modern design, dual vortex flushing, comfort height, and easy cleaning in a single package, and it is backed by nearly 2,600 reviews averaging 4.3 stars. The WOODBRIDGEE B0940-F-C is the right pick if flushing performance and WaterSense efficiency matter more than aesthetics, and the DeerValley DV-1F52812 is the clear winner for tight powder rooms where depth is the limiting factor.
For tall users and accessibility-focused buyers, the HOROW T0338W offers ADA chair height with the rare option of a 10-inch rough-in. For a bold statement fixture, the Swiss Madison Ivy in glossy black is the only one-piece toilet in our roundup that delivers true designer style. Whichever model you choose, measure your rough-in first, prioritize MaP score over GPF, and plan on recruiting a helper for the install. A one-piece toilet is heavy, but it is the last toilet you will buy for a long time.
