If standing back up from the toilet has turned into a small negotiation with your knees, the fix is simpler than you think: you need a taller bowl. An ADA toilet puts the seat at roughly 17 inches off the floor instead of the standard 15, so the trip down and back up takes far less effort. This guide covers nine toilets that meet that height — from a basic one-piece to a full smart bidet seat that opens its own lid — and tells you which one fits your bathroom, your plumbing, and your budget.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Height is only half the story here. Rough-in distance, bowl shape, and whether you have an outlet near the floor decide whether a model will even fit your bathroom. Below you’ll find the numbers that matter, the install headaches owners actually hit, and a clear pick for every situation, all in one place on ada toilets.
Top Picks
How To Choose The Best ADA Toilets
The single most common mistake is buying on height alone. A toilet that sits at the right level but misses your rough-in by an inch will not bolt to your floor without moving the drain. Measure first, then shop.
Measure your rough-in before anything else
Rough-in is the distance from the finished back wall to the center of the floor drain. Most homes are built at 12 inches. Several picks here are built for exactly that 12-inch rough-in, and one HOROW model is offered in both 10-inch and 12-inch versions. If your measurement lands somewhere else, check the spec sheet before you order.
Seat height: 17 inches versus 20 inches
ADA-compliant models in this list put the seat between 17 and 17.5 inches off the floor. That is the accessible standard and it suits most adults with knee or hip trouble. A taller bowl exists too — the Convenient Height model measures 22 inches to the top of the seat — and it is aimed at very tall users or people who need to stand almost without bending. A bowl that high can be awkward for children and shorter adults.
One-piece or two-piece
A one-piece toilet molds the tank and bowl into a single ceramic shell, which leaves fewer seams to collect grime and no gap where a tank meets a bowl. A two-piece, like the TOTO Drake, ships as a separate tank and bowl and bolts together — often easier to carry up stairs in two loads, but it gives you one more joint to keep sealed.
Skirted versus exposed trapway
A skirted toilet hides the curved waste pipe behind a smooth ceramic panel, so there is no dusty ledge at the back. The trade-off is that the floor bolts sit behind that panel, and reaching them takes a deep socket and patience. Exposed-trapway models are quicker to bolt down but collect dust behind the bowl.
Match the seat to the person using it
Heated seats, warm-water wash, and air dryers change the daily routine more than any flush upgrade. They also need a power outlet within reach of the toilet. If there is no outlet near the floor, a standard-height ceramic toilet with a good flush is the safer buy.

Detailed Reviews
1. WOODBRIDGE B0930S Smart Toilet
Our pick — 4.5+★ from 250+ verified ratings; the strongest balance of quality and price.
A 17-3/8-inch smart toilet with a 1000g flush and a foam shield — no plumber needed to move a wall.
What you get for the mid-range money is a genuinely complete smart toilet. The foam shield lays a soft layer over the water before every use, which cuts splashback and keeps the bowl cleaner between scrubs. The MaP score of 1000 grams is the measurement buyers watch, and it means the flush clears waste in a single pass. A 17-3/8-inch floor-to-seat height puts it in ADA territory, so sitting down and standing up take noticeably less effort than a standard bowl.
What wins people over is the seam-free one-piece shell. Porcelain this smooth and this tight leaves nowhere for grime to sit, and the enclosed plumbing behind the skirt makes the outside a single wipe. The bidet is adjustable in front, rear, and oscillating modes, with water temperature and spray position you can tune to your own routine. The heated seat has adjustable temperature, and the moving dryer travels back and forth at low, medium, or high speed so you can cut back on paper.
The honest catch is the footprint. At 112 pounds it is one of the heavier units here, and the 27.63″D x 16.53″W x 19.75″H body needs room for the water valve behind it. Buyers report plumbing work when the valve sits too close to the wall. The remote is also not backlit, so if you want to change settings in the dark you will be fumbling. Set against that, the auto-open lid, foot sensor, and auto-flush after you walk away do more for daily comfort than almost anything else in this price band.
MaP 1000g flush power
- 1000g MaP score clears waste in one flush, every time.
- 17-3/8″ seat height meets ADA and eases the sit-to-stand motion.
- Foam shield cuts splashback and keeps the bowl cleaner.
- Foot sensor and auto open/close make the whole routine hands-free.
needs power outlet
- 112 pounds — a two-person lift, no exceptions.
- Remote is not backlit, awkward after dark.
- Needs clearance behind the bowl for the water valve.
top flush score: anyone who wants the automated lid, warm seat, and foam shield without hiring a plumber to move a wall.
check wiring first: measure the gap between the bowl and the shut-off valve before the box arrives.
2. DeerValley Dual Flush Toilet
A skirted one-piece with dual flush and a slow-close seat, at a price that undercuts the smart toilets.
If you want the clean skirted look without paying for a motorized anything, this is the one to start with. The dual flush gives you 1.6 GPF for a full flush and 1.1 GPF for a half flush, so everyday trips use less water. The skirted ceramic side hides the trapway, which means no dusty ledge behind the bowl. The packaging weighs in at 99 pounds against the WOODBRIDGE smart toilet’s 112, so moving it into place is a little kinder on your back.
What the design gets right is restraint. There is one smooth surface, a slow-close seat that will not slam at 2 a.m., and the bolt holes are reachable from the side. Owners mention a solo install under 25 minutes when the floor is already prepped. The standard 16 7/8-inch seat height is the one thing to check carefully — this is the shortest seat on the list, so if the whole point is easier standing, look at the taller DeerValley above it in this list.
Flush performance draws honest complaints from a handful of owners: the tank mechanism can keep running if it is not adjusted right, and the lid feels light against the ceramic body. These are the sort of issues a careful setup handles, but they are worth knowing before you commit. What evens the ledger is the value — a streamlined one-piece that looks far beyond its price tier.
solid value pick: you want a clean one-piece look at entry-level cost and your knees are already in decent shape.
skip smart features: the whole reason you are shopping is to raise the seat — this sits at 16 7/8 inches, not ADA height.
3. DeerValley DV-1F0437 Toilet
A chair-height one-piece that actually fits where a standard toilet barely does.
Start with the number that decides it. The bowl measures 26.77″D x 14.5″W x 26.6″H, and the seat sits at 17 1/2 inches, so you get full ADA height and a compact body. That combination is rare — most tall toilets are built on a deep footprint. If your bathroom is tight, this is the one that gives you the height without eating the floor space.
The rimless bowl is the other thing worth pointing out. There is no hidden rim channel for grime to build up, so cleaning is a single pass around the inside with the soft-close seat flipped up. The dual flush runs 1.28 GPF or 1.1 GPF with a 1000g MaP score, and the nozzles use that pressure across the whole bowl. The ceramic is glazed against staining, and the seat is a thickened PP design that sits wider than standard.
The install is the honest rub. The access holes on both sides are narrow, and more than one owner mentions using a socket rather than fingers to reach the mounting bolts. It also weighs 94.8 pounds and comes as a single shell, so a second pair of hands helps for the final lift onto the flange. Once it is down and the wax ring is seated, the extra effort fades from memory.
easy on knees: a short or narrow bathroom that still needs a 17 1/2-inch seat for easier standing.
measure your space: the side bolt holes are tight — bring a deep socket and a friend for the lift.
4. HOROW T0338W Toilet
Compact, chair-height, and priced where most people can actually buy it.
The measurements here are the point. At 26.6″D x 15″W x 26″H this is a narrow one-piece that slips into a small bathroom, and the 17.3-inch seat height clears the ADA bar. That makes it a sensible swap for a first-floor powder room or an apartment where space is the constraint and cost is the other one.
The flush uses siphon action with a fully glazed 2-inch trapway — the pipe the waste travels through — so the bowl clears without a second push. Dual flush runs 1.1 or 1.6 GPF, and the 1000g MaP rating sits alongside the more expensive names. The soft-close seat screws down rather than snapping on, so it stays put. HOROW backs it with a one-year limited warranty and a 12-hour response line.
Set against the niche picks, this is the one with the widest everyday appeal — people buy it for tall family members, for older parents, and for themselves. The recurring note is the side access: the cutouts are small, and tightening the mounting nuts takes a deep socket and some patience. A second person makes the lift easier too. Neither is a deal-breaker, but both are real.
17.3 inch comfort height: you get ADA height, a 1000g flush, and a compact footprint with none of the smart features to maintain.
heavy one-piece lift: tight side cutouts make the floor bolts fiddly, so budget an hour and a socket set rather than twenty minutes.
straightforward install: this is the one to pick when you want chair height, a strong flush, and no power outlet needed.
verify rough-in size: your rough-in — HOROW offers 10-inch and 12-inch versions, so confirm which your floor needs.
5. TOTO Drake Toilet
The one plumbers keep naming when you ask what they would put in their own house.
The Drake’s trick is TORNADO FLUSH, which sends water around the bowl in a swirl instead of straight down from a rim. That swirl washes the whole surface on every flush, and the CEFIONTECT glaze is an extra-smooth finish that stops waste from sticking in the first place. The 1.6 GPF single-flush design uses a wide 3-inch flush valve and a siphon jet, so one pull does the job.
Universal Height is the phrase TOTO uses for its taller bowl, and the company states these models are capable of meeting the ADA height requirement. The elongated oval gives more room front to back, and the 94-pound body fits a standard 12-inch rough-in with a left-hand trip lever.
What owners keep coming back to is the bowl staying clean longer. The glaze and the swirl together make scrubbing a rarer chore than most toilets demand. The trade-off is completeness: the tank and bowl arrive with hardware, but the wax ring, flange bolts, and supply line are purchased separately, and the seat is not in the box either. Budget for those small extras and check your supply valve before install day.
trusted brand choice: you want the most proven flush design here and you do not need a heated seat or an automatic lid.
add a seat: a wax ring, flange bolts, a supply line, and a seat — none of them ship in the box.
6. 20 inch Extra Tall Toilet
For the six-foot-six crowd and anyone whose knees need a nearly standing start.
The bowl measures 20-3/4 inches tall, and the top of the seat sits 22 inches off the floor. That is a different category from the 17-inch ADA toilets around it — this is built for very tall people or for anyone who wants to rise with almost no knee bend. It is marketed for bathroom safety, easing the sit-down and stand-up motion. It is designed and engineered by Convenient Height Co. in Massachusetts.
The other numbers back up the build. The dual flush runs 1.28 GPF or 0.9 GPF through a solid metal handle, and the body weighs 120 pounds so it sits planted. Users well over six feet describe their knees coming level with their hips instead of dropping below them. It is approved by the Board of Registration of Plumbers and CEC, and may qualify as a medical-expense tax deduction.
Be honest about who this is not for. A 22-inch seat top is too high for children and awkward for shorter adults, and one reviewer notes a step stool would be needed for small kids. The plastic seat and the handle also draw fair criticism for the price — the handle is listed as solid metal, and a few buyers expected a porcelain seat at this tier. The flush cable and the tank bolts need careful routing during install.
extra tall 20 inch bowl: tall adults and anyone with arthritic knees who has been stacking a plastic riser on a standard bowl.
limited ceiling clearance: a short or mixed-height household, where a 22-inch seat top will feel like climbing.
tall user match: a very tall user or someone who needs to stand without deep knee bend.
weigh the height: it is the tallest seat here by a wide margin, and that height is a real obstacle for shorter family members.
7. EPLO U8MAX Smart Toilet
A full smart bidet with the seat height comfortably in ADA territory.
The 17.41-inch floor-to-seat height qualifies this for ADA accessible installations, so the sit-to-stand motion is easier for anyone with sore knees. The rest is smart-toilet kit: the lid opens as you approach, the seat heats to your set temperature, and a foot sensor handles opening, closing, and flushing when you would rather not touch anything. Four-season temperature sensing adjusts the seat, water, and dryer to the room.
For flush power there is a 1000g MaP score with your choice of 1.6 GPF full or 1.1 GPF half. The foam shield coats the water before use so splashback is reduced and the bowl stays cleaner between scrubs. The moving dryer travels and adjusts for speed and temperature, and the bidet offers front, rear, and oscillating washes with adjustable pressure and spray position.
Where it falls a little short of its EPLO stablemate is adjustability at the bidet. One owner finds the stream weak and the pressure not adjustable in a way that suits two different users, and the foot sensor can occasionally close and flush unexpectedly. On the plus side, the whole unit weighs 116 pounds and the installation kit includes the three-way angle valve, sealing flange, and mounting hardware, so you are not hunting for parts on install day.
feature-rich upgrade: a first smart toilet where ADA height and a 1000g flush are non-negotiable.
budget concerns first: you want fine control over bidet pressure for two different users — the adjustment range is the weak spot here.
8. EPLO iX7 PRO Smart Toilet
The smart toilet built for houses where the water pressure never quite cooperated.
The feature that separates this from the U8MAX is the booster pump. It is a small motor that assists the flush when your household water pressure is low, and the siphon jet does the rest. One owner with pressure in the 30–35 psi range says the pump gave a consistent flush where a pressure-only model had struggled. The tank design means it still flushes during a power cut, using the side button or the foot kick.
Around that core sits the usual premium smart package. The seat sits at 17 inches for ADA-friendly sitting and standing, and the built-in tank keeps the silhouette compact at 27.2″D x 16″W x 18.8″H. The heated seat, instant warm water, adjustable high-speed dryer, night light, and LED temperature display are all controlled from the remote or the side panel. Auto-open runs from a sensor or a foot kick, and it can be switched off if you prefer manual.
The recurring gripe is the lid. The automatic operation gets mixed feedback, with a few owners noting it can behave unexpectedly. Noise is the other note — one buyer calls it loud and says a quieter toilet was not worth paying double for. Weighing 103 pounds, it is lighter than the WOODBRIDGE smart toilet by 9 pounds, so the lift is a touch more manageable.
strong flush backup: older plumbing where pressure is inconsistent and the flush needs a little help.
pro install advised: confirm a power outlet near the floor and check the lid behavior is acceptable to you — it is the most-discussed weak point.
9. HOROW T38P Smart Toilet
The most feature-dense smart toilet here, with a heated seat you can dial in four ways.
The heated seat gives you 4 adjustable levels, and the ADA height keeps the whole thing easy to rise from. The bidet is self-cleaning after each use, with multiple wash modes and adjustable pressure and temperature. The lid senses your approach, opens, and closes behind you. Around that sits a foam shield, a deodorizer, ambient lighting, and a foot kick for touch-free flushing, plus a manual flush backup for power cuts.
The flush uses a pump-driven 1000 gram MaP score, with dual flush at either 0.9 GPF for a half flush or 1.32 GPF for a full one. The elongated skirted body keeps the outside simple to wipe, and the whole thing installs on a 12-inch rough-in. The finishing touch is the LED lighting, which guides you in the dark without blinding you.
The caveats are worth knowing up front. This unit needs a power outlet near the floor, and owners note the installation cost can climb if pipes or electric need moving. The foaming solution and the blackout-flush battery pack are not in the box, so order them from HOROW. The flush also leaves paper behind on light settings, and one buyer using a Squatty Potty found the raised feet misaligned the sensor and caused repeated half-flushes.
foam shield bidet combo: a 4-level heated seat, a pump-assisted 1000g flush, and a self-cleaning bidet all in one footprint.
higher upfront cost: it wants a nearby outlet and a straightforward install — customers note the add-on costs and the light-flush paper issue.
built for comfort: a bathroom that already has power at the floor and a straightforward 12-inch rough-in.
not for renters: a Squatty Potty user — the raised feet misalign the sensor and cause repeated flushes.
Know the Specs
What MaP score actually measures
MaP stands for Maximum Performance, and the score is a weight in grams of material a toilet clears in a single flush. A 1000g score is the top of the scale, which is why several picks here list it. Higher numbers mean fewer second flushes and fewer clogs, but almost every model in this list clears that bar, so do not let the score alone decide it. Look at the flush type next — siphon, vortex swirl, or pump-assisted.
Rough-in distance and why it stops a sale
Rough-in is measured from the finished wall to the center of the floor drain. Standard builds use 12 inches. Order the wrong one and the toilet will not seat on the flange without moving the drain. One HOROW model is offered in both 10-inch and 12-inch versions, so pick the matching one before checkout. If you are unsure, measure twice and ask a plumber once.
GPF and what the number means
GPF is gallons per flush. A dual-flush system gives you a smaller half flush and a larger full flush, often 1.1 and 1.6 GPF. Using less water per trip adds up over a year, and modern bowl shapes flush well on less water than old 3.5 GPF models. The trade-off is that a light flush can leave paper behind, so check the full-flush rating if that matters to you.
Power, outlets, and smart features
Every smart toilet here needs electricity for the heated seat, warm water, dryer, and auto lid. A standard grounded outlet near the floor is what you need. If the outlet is on the far wall, the install cost climbs. Models with a built-in tank and a manual flush button will still work in a power cut, which is worth checking if you live somewhere with outages.

The Bottom Line
For most people shopping for the best ADA toilets, the WOODBRIDGE B0930S is the easiest recommendation. It pairs the 17-3/8-inch seat height that makes standing easier with a 1000g flush, a foam shield, and an auto-open lid — the full routine, hands-free, without a plumber’s visit. It is the crowd favorite by a comfortable margin, and the feature set explains why.
If your priority is the flush alone, the TOTO Drake is the engineering pick — TORNADO FLUSH and CEFIONTECT keep the bowl cleaner between scrubs, and you add only a wax ring and seat. For very tall users or anyone who needs to stand with almost no knee bend, the Convenient Height 20-inch is the one to reach for.
And if your house runs on low water pressure, the EPLO iX7-PRO is worth a serious look — the booster pump makes the flush reliable where a gravity toilet struggles.
