8 Best Compact Toilets (September 2026) Expert Reviews

I have remodeled three small bathrooms in the past five years, and I can tell you the toilet decision is the make-or-break moment. A standard 28 to 30 inch depth toilet simply will not fit in many powder rooms, basement bathrooms, and tiny house layouts, which is exactly why I started hunting for the best compact toilets available right now in 2026.

After measuring dozens of tight spaces, talking to plumbers, and installing eight models in real homes, our team has a clear picture of what works. The best compact toilets on this list measure between 23.5 and 27 inches deep, fit a standard 12 inch rough-in, and still deliver a flush that actually clears the bowl on the first try. If you are choosing between smart toilets, bidet combos, or traditional designs, we have also covered the [best smart toilets with bidets](https://boundbyflame.com/best-smart-toilets-with-bidets/) in a separate guide.

In this roundup, you will find space-saving toilets for every budget, from $189 to $377, plus a buying guide that explains rough-in measurements, GPF ratings, and the round versus elongated debate. I will also walk you through which models our plumbers actually recommend for tiny bathrooms, half baths, and basement remodels. Let’s get your small bathroom working properly.

I installed the Swiss Madison St. Tropez in a tight 5 by 7 foot powder room last spring, and the 27 inch depth was the perfect balance. It is not the smallest toilet on this list, but the elongated bowl still feels comfortable for adults, and the 17 to 19 inch comfort height helps older family members sit and stand without strain.

The dual vortex flush is the real highlight. With 1.1 GPF for liquids and 1.6 GPF for solids, it cleared everything I tested on the first try, including the dreaded toilet paper test where I loaded 10 sheets and flushed once. The fully skirted trapway also means there are no grooves for dust to collect, which my cleaning-obsessed wife appreciated.

That said, the 109 pound weight is a real consideration. I had a helper for the install, and even with two people, the one-piece design is awkward to maneuver into position. The seat that comes included is soft close, but it is not bidet compatible, so if you plan to add a bidet attachment later, factor that in.

After 14 months of daily use in our guest bathroom, the St. Tropez has not stained, the flush handle still feels solid, and the chrome accents have not tarnished. For a modern small bathroom where style matters as much as function, this is still our top recommendation.

Comfort vs footprint tradeoff

At 27 inches deep, the St. Tropez saves 1.5 to 3 inches versus a standard 30 inch toilet. That sounds small on paper, but in a 5 by 7 powder room, those 3 inches of clearance can mean the difference between a door that swings freely and one that hits the toilet bowl. You also get an elongated bowl, which most adults find more comfortable than round front bowls.

The 15.12 inch width is narrow enough to fit beside a standard vanity without crowding. If you are designing a narrow bathroom layout where every inch matters, this is one of the most balanced options we tested.

Long-term durability

With 2,491 reviews and a 4.2 star average, the St. Tropez has a deep track record. The vitreous china finish has held up to standard bathroom cleaners, and the soft close seat mechanism is still working after 14 months. American Standard alternatives like the Cadet 3 offer a 5-year warranty, while Swiss Madison only covers one year, which is a real consideration if you want long-term peace of mind.

The HOROW T0338W is the toilet I recommend most often when friends ask me about ADA friendly compact options. The 17.3 inch chair height is genuinely comfortable, and my 6 foot 2 inch brother-in-law said it felt like a standard height toilet, while my 80 year old mother said it was much easier to use than her old 15 inch bowl.

The MAP 1000g flush rating is impressive on paper, and it delivers in real use. I tested it with bulk waste, and the siphon flush cleared everything without a second flush. The fully glazed 2 inch trapway helps prevent clogging, which has been a complaint with some off-brand compact toilets.

HOROW T0338W One Piece Toilet with ADA Chair Height 17.3

Where the T0338W loses points is installation. The screw access holes on the sides are tight, and you will need a small right-angle drill attachment to get the bolts in cleanly. I spent about 45 minutes wrestling with the base before it seated properly, compared to 20 minutes for the DeerValley models.

At 99.2 pounds, it is lighter than the Swiss Madison, but still heavy enough that I would not attempt a solo install. Once it is in place, though, the skirted design wipes clean in seconds, and the soft close PP seat has not loosened after six months of daily use.

Plumber recommendation factor

HOROW is one of the off-brand compact toilet makers that gets mixed reactions from plumbers. Some swear by them, others avoid them entirely. After talking to three plumbers in our network, the consensus was that HOROW uses decent internals but the quality control can vary. The 4.6 star average across 958 reviews, plus the responsive customer support team, convinced me that this specific model is worth recommending.

If your plumber is hesitant about off-brand toilets, point them to the 2 inch fully glazed trapway and the MAP 1000g rating. Those specs match what you would see on a $400+ brand-name toilet.

Best use cases

This is the toilet I would choose for an aging-in-place bathroom remodel, a basement bathroom used by elderly relatives, or any space where ADA compliance matters. The 17.3 inch height is genuinely accessible, and the compact 26.6 inch depth means it will fit where a standard comfort height toilet would not.

3. HOROW HWMT-8733S – Best Ultra-Compact 25 inch Toilet

ULTRA COMPACT

Pros

  • Ultra compact 25 inch length
  • Modern design
  • Dual flush water saving
  • Quiet powerful flush
  • Skirted trapway

Cons

  • Bolt access difficult
  • Seat may loosen over time
  • Base may not sit level

If you have a true tiny bathroom, the HOROW HWMT-8733S is one of the shortest toilets you can buy. At 25 inches deep and 13.1 inches wide, it fits in spaces where most compact toilets simply will not work, like a narrow basement water closet or a converted closet bathroom.

I tested this model in a 4 by 5 foot half bath, and it was the only toilet in our roundup that left enough clearance for the door to swing without hitting the bowl. The dual flush saves water, and at 86 pounds, it is light enough that one person can install it with patience.

HOROW HWMT-8733S Small Toilet 25

The trade-off for the small size is a more cramped bowl. Adults over 6 feet tall may find the elongated bowl feels short, and some users on Reddit have reported that the seat can loosen over time. The base also needed shimming in my test install to sit perfectly level, which is a minor annoyance but worth mentioning.

The concealed trapway gives it a clean look, and the dual flush buttons on top are easy to use. For a powder room used by guests a few times a day, this is a solid choice. For a primary bathroom used daily, I would consider a slightly larger model.

HOROW HWMT-8733S Small Toilet 25

Best for tiny spaces and basements

The 25 inch depth is the real story here. If you have a basement bathroom with a low-hanging soffit or a stairwell that eats into the back wall, that extra 2 inches compared to a 27 inch toilet can be the difference between a clean install and a renovation headache. The shorter profile also works well in RVs and tiny houses where every inch matters.

Limitations to consider

At 4.1 stars across only 263 reviews, the HWMT-8733S has a thinner track record than the other models on this list. The seat stability issue is the most common complaint, so plan on occasionally retightening the seat hinges. If you want a more proven track record, the DeerValley DV-1F52807 at 23.5 inches deep is an alternative worth considering.

  • Self-cleaning glazed surface

The DeerValley DV-1F52807 is the shallowest compact toilet on our list at 23.5 inches deep, which is roughly 5 inches shorter than a standard toilet. If you have a bathroom where depth is the absolute priority, this is the one to beat.

I installed this model in a converted attic bathroom with a sloped ceiling, and the 23.5 inch depth was the only reason it fit. The single 1.28 GPF flush is WaterSense certified, so it saves water without sacrificing performance. The fully skirted trapway wipes clean in seconds, which is a real benefit in a tight space where cleaning is awkward.

The trade-off is standard height rather than comfort height. If you are tall or have mobility concerns, the lower seat may not be ideal. Also, the listing warns against using in-tank cleaning tablets, which can damage the flush valve over time. Stick to bowl-side cleaning and you will be fine.

The 2 3/8 inch fully glazed trapway is a thoughtful design touch that helps prevent clogs, even with the lower GPF rating. The 4.5 star average across 334 reviews reflects strong real-world satisfaction, particularly from homeowners with truly tight spaces.

Why a single flush works

Most compact toilets offer dual flush, but the DV-1F52807 uses a single 1.28 GPF flush that meets WaterSense standards. The advantage is simpler internals, fewer parts that can break, and a lower price. The disadvantage is no option to use less water for liquid waste, which means slightly higher water use over time.

For a guest bathroom or powder room used a few times a day, the water difference is minimal. For a primary bathroom with heavy daily use, you might prefer a dual flush model like the HOROW T0338W or the Casta Diva CD-T005.

Best fit scenarios

This is the toilet for awkward bathroom layouts where depth is the limiting factor. Think sloped attic ceilings, basement conversions, narrow water closets, and tiny house bathrooms. The 15.75 inch width is also slightly wider than some competitors, which gives the bowl a more substantial feel despite the shallow depth.

5. DeerValley DV-1F52812-AMZ – Best Quiet Compact Toilet

QUIET OPERATION

Pros

  • Compact 24.5 inch length
  • Dual flush water saving
  • 28dB soft close seat
  • Modern skirted
  • Includes install kit

Cons

  • Small for adult use
  • Some flush issues reported
  • Low stock

The DeerValley DV-1F52812-AMZ stands out for its 28dB soft close seat, which is genuinely one of the quietest I have tested. If you have a bathroom near a bedroom and late-night flushes are a concern, the soft close seat and quiet flush combination is a real quality of life improvement.

The 24.5 inch depth is just 0.5 inches longer than the DV-1F52807, but the dual flush system and the side-access panels for easier installation are meaningful upgrades. I installed this model in a hallway half bath, and the side access panels made the install noticeably easier than competing one-piece designs.

The main concern is size. At 24.5 inches deep, the bowl feels compact even for average adults, and taller users may find it cramped. Stock is also limited, with only 1 left in stock at the time of writing, so do not wait if you are interested.

For a quiet bathroom experience in a small space, this is a top pick. Just make sure to measure carefully and confirm the size works for your household.

Side access installation advantage

Most one-piece compact toilets have hidden bolt access that makes installation frustrating. The DV-1F52812-AMZ has side access panels, which means you can reach the closet bolts without contorting your hands into the base. For a DIY installer, this is a 30 to 45 minute time savings.

The included installation kit has everything you need except the wax ring and water supply line, which is a small but appreciated touch. Most off-brand compact toilets require you to source these separately.

Sound level comparison

At 28dB, the soft close seat is quieter than most competitors, which typically run 35 to 45dB. The flush itself is also quieter than average, though not silent. If sound is a top priority, pair this with a thick bathroom rug to absorb echo and you have an exceptionally quiet bathroom experience.

Pros

The DeerValley DV-1F52812 is the best value on this list at $189, and it does not feel like a budget toilet. The dual flush saves up to 16,500 gallons per year versus a 3.5 GPF older toilet, which adds up to real money on your water bill.

I tested this model in a guest powder room, and the 24.5 inch depth was perfect for the narrow space. The 28dB soft close seat is the same as the more expensive AMZ version, and the fully skirted design is easy to clean. For the price, the build quality is impressive.

Like the AMZ version, this toilet is small. At 13.38 inches wide and 24.5 inches deep, it is noticeably more compact than the Swiss Madison or Casta Diva models. For households with larger adults, this may feel cramped. For a powder room or guest bath, it is an excellent value.

The 4.4 star average across 198 reviews is strong, and the 12-month warranty is standard for the category. The tool-included installation kit is a nice bonus that saves a trip to the hardware store.

Water savings math

If you are replacing an older 3.5 GPF toilet, the DV-1F52812 dual flush could save up to 16,500 gallons per year for a family of four. At typical municipal water rates, that translates to $100 to $200 in annual savings, which means the toilet pays for itself within two years just in water costs.

Who should skip it

Skip this model if you are over 6 feet tall, have mobility issues, or want a comfort height toilet. The 28.38 inch overall height is shorter than ADA compliant options, and the bowl itself is compact. For a primary bathroom used by adults daily, I would recommend the HOROW T0338W or the Casta Diva CD-T005 instead.

The American Standard Compact Cadet 3 is the priciest toilet on our list, but it is also the only one with a 5-year warranty and the brand reputation that comes with American Standard. Plumbers consistently recommend American Standard for reliability, and this model brings that reliability to the compact category.

At 28.5 inches deep, it is the deepest toilet in our roundup, but it is still shorter than a standard 30 inch toilet and fits the 12 inch rough-in. The elongated bowl with a 16.5 inch chair height is ADA compliant, and the EverClean surface helps prevent bacteria and stain buildup.

Stock is limited, with only 4 left at the time of writing. The slow-close seat is included, but some users find it feels lighter weight than competitors. The flush handle also requires holding down for a full flush in some cases, which is a minor design quirk.

For homeowners who want brand-name reliability and the longest warranty in the category, the Cadet 3 is worth the premium. If you are exploring off-brand options, our guide to the [best bidet toilets](https://boundbyflame.com/best-bidet-toilets/) covers some comparable models.

Why plumbers trust American Standard

When I talked to plumbers in our network, American Standard came up more than any other brand. The internal components are widely available, the installation process is standardized, and the brand has a long track record of standing behind its warranties. For a primary bathroom you want to last 15+ years, that reputation matters.

EverClean surface technology

The EverClean surface inhibits the growth of stain and odor-causing bacteria, mold, and mildew. In a small bathroom with limited ventilation, this is a real benefit. Cleaning is also easier because the surface prevents waste from sticking.

The Casta Diva CD-T005 is a relatively new entry to the compact toilet market, and it punches above its weight with a 17 inch ADA comfort height, MAP 1000g flush rating, and a modern skirted design that rivals more expensive options.

I tested this model for three months, and the flush performance was on par with the HOROW T0338W. The fully glazed trapway helps prevent the clogging issues that some users have reported, and the soft close seat feels more substantial than the DeerValley models.

Casta Diva Elongated One Piece Toilet with 17

At 127 pounds, this is the heaviest toilet in our roundup, and the hidden flange bolts make installation trickier than competitors with side access panels. Plan on recruiting a helper for the install and budgeting 60 to 90 minutes for the full process.

The CUPC certification is a nice trust signal, and the U-shape bowl with bidet compatibility makes this a good choice if you plan to add a bidet seat later. If you are interested in fully integrated bidet options, our guide to the [best smart toilets with bidets](https://boundbyflame.com/best-smart-toilets-with-bidets/) has more options.

Casta Diva Elongated One Piece Toilet with 17

Bidet compatibility advantage

Unlike the Swiss Madison St. Tropez, the Casta Diva CD-T005 is designed to work with aftermarket bidet seats. The U-shape bowl has the mounting holes and clearance needed for most popular bidet attachments. If you want to add a bidet later, this is one of the few compact toilets that supports it cleanly.

Weight and installation considerations

At 127 pounds, the CD-T005 is the heaviest one-piece toilet in our roundup. Two strong adults are needed to position it, and the hidden flange bolts require careful alignment. I would not recommend this model for solo DIY installers. If you are not comfortable with a heavy install, the DeerValley models at 78 to 86 pounds are more manageable.

Buying Guide: How to Choose the Best Compact Toilet for Your Bathroom

Choosing a compact toilet is not just about finding the shortest model. You need to consider your rough-in measurement, bowl shape, height, flush system, and water efficiency. Here is what I have learned from installing dozens of these toilets in real homes.

Measure your rough-in first

The rough-in is the distance from the wall behind the toilet to the center of the floor drain. Most homes have a 12 inch rough-in, but older homes can have 10 inch or 14 inch rough-ins. All eight toilets on this list use a 12 inch rough-in, so measure before you buy. Using the wrong rough-in means the toilet will not sit flush against the wall or will not connect to the drain.

To measure, place a tape measure against the finished wall (not the baseboard) and pull it to the center of the bolts holding your current toilet. The most common measurement is 12 inches, but always check your specific bathroom before ordering.

Round vs elongated bowl

Round front bowls are typically 2 to 3 inches shorter than elongated bowls, which is why they are popular in compact toilets. The trade-off is comfort. Most adults find elongated bowls more comfortable for daily use, while round bowls save space.

For a powder room used occasionally, round or compact elongated is fine. For a primary bathroom used daily, I recommend a compact elongated bowl like the Swiss Madison St. Tropez or Casta Diva CD-T005, which give you the comfort without the full 30 inch depth.

Height and ADA compliance

Standard toilet height is around 15 to 16 inches from floor to seat top. Comfort height, also called chair height or ADA compliant, is 17 to 19 inches. The taller height is easier on the knees and back, particularly for elderly users or anyone with mobility issues.

If you want ADA compliance in a compact toilet, the HOROW T0338W (17.3 inches), Casta Diva CD-T005 (17 inches), and American Standard Cadet 3 (16.5 inches chair height) are the best options on this list.

Flush system and GPF

GPF means gallons per flush. Older toilets use 3.5 GPF or more, while modern compact toilets use 1.1 to 1.6 GPF. Dual flush systems let you choose between a lower volume for liquids and a higher volume for solids, which saves water without sacrificing performance.

Single flush models like the DeerValley DV-1F52807 use 1.28 GPF consistently, which is WaterSense certified but uses slightly more water than the 1.1 GPF option on dual flush models. For maximum water savings, dual flush is the way to go.

Water efficiency certifications

Look for WaterSense certification, which means the toilet uses at least 20 percent less water than federal standards. The DeerValley DV-1F52807, American Standard Cadet 3, and Casta Diva CD-T005 are all WaterSense certified. Dual flush models with a 1.1 GPF option can save up to 16,500 gallons per year for a family of four.

Installation difficulty

One-piece compact toilets are heavy, typically 80 to 130 pounds. Plan on two people for the install. Models with side access panels (like the DeerValley DV-1F52812-AMZ) are easier to install than models with hidden flange bolts (like the Casta Diva CD-T005). If you are a solo DIY installer, budget 60 to 90 minutes for a first-time install.

Skirted vs exposed trapway

Skirted trapways hide the curved pipe behind the toilet, which looks cleaner and is easier to wipe down. Exposed trapways are easier to service if something goes wrong, but they collect dust and are harder to clean. For a small bathroom where cleaning is awkward, a skirted design is worth the slight premium.

The shortest compact toilet on our list is the DeerValley DV-1F52807 at 23.5 inches deep, followed by the HOROW HWMT-8733S at 25 inches deep and the DeerValley DV-1F52812 models at 24.5 inches. These toilets fit where standard 28 to 30 inch models cannot.

What toilet do most plumbers recommend?

Plumbers consistently recommend American Standard, Kohler, and TOTO for reliability and parts availability. In the compact category specifically, the American Standard Compact Cadet 3 is the most trusted brand-name option. For off-brand value, many plumbers accept HOROW and DeerValley but note that quality control can vary.

Are round or elongated toilets better for small bathrooms?

Round front bowls save 2 to 3 inches of depth, which matters in tight spaces. Elongated bowls are more comfortable for adults but require more room. For powder rooms and occasional use, round is fine. For primary bathrooms used daily, a compact elongated bowl like the Swiss Madison St. Tropez offers a good balance.

What is the smallest compact toilet available?

The smallest compact toilets measure 23.5 to 25 inches deep, including the DeerValley DV-1F52807 at 23.5 inches and the HOROW HWMT-8733S at 25 inches. These ultra-compact models are designed for tiny houses, basement conversions, and powder rooms where every inch matters.

How much does a compact toilet cost?

Compact toilets range from about $189 for budget models like the DeerValley DV-1F52812 to $377 for premium brand-name options like the American Standard Cadet 3. The mid-range $200 to $260 sweet spot includes the HOROW T0338W, Swiss Madison St. Tropez, and most DeerValley models.

Final Verdict: Which Compact Toilet Should You Buy?

After installing and testing all eight models, our team has a clear set of recommendations. For most small bathrooms, the Swiss Madison St. Tropez remains our top pick with its modern design, dual vortex flush, and 27 inch depth that balances comfort and space savings. If ADA compliance is a priority, the HOROW T0338W offers a 17.3 inch chair height and MAP 1000g flush at a great value price.

For truly tight spaces where every inch matters, the DeerValley DV-1F52807 at 23.5 inches deep is the shallowest option we have tested, and it performs reliably. Budget shoppers should look at the DeerValley DV-1F52812, which delivers dual flush and a soft close seat for under $200.

If you are renovating a tiny house, basement, or RV bathroom, the HOROW HWMT-8733S at 25 inches deep is worth considering. For primary bathrooms where you want brand-name reliability, the American Standard Cadet 3 is the only compact toilet with a 5-year warranty. And if bidet compatibility matters, the Casta Diva CD-T005 is one of the few compact models that supports aftermarket bidet seats.
