If you are shopping for a toilet that makes sitting down and standing up noticeably easier, the single number that matters most is the seat height. Standard toilets sit around 15 inches from the floor, but an ADA toilet — designed to meet the Americans with Disabilities Act guidelines — starts at 17 inches and often goes higher, putting your knees at a more natural angle and taking pressure off your lower back and joints. This guide uses real specs and verified buyer feedback to help you choose the best ADA toilet for your home.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. 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.
Whether you are outfitting a bathroom for aging parents, recovering from surgery, or simply want a more comfortable daily experience, choosing the right ada toilet depends on flush performance, seat height, and ease of cleaning — and this guide breaks down every key difference so you get the best fit for your home.

How To Choose The Best ADA Toilet
An ADA toilet is more than just a taller seat. The right ADA toilet depends on your bathroom space, preferred flush type, and cleaning tolerance. Here are the three most important factors to weigh before you buy.
Seat Height and Bowl Shape
The ADA standard calls for a seat height of 17 to 19 inches from the floor to the top of the seat. That extra height (a couple of inches above a standard 15-inch toilet) makes a big difference for anyone with knee or back issues, because you do not have to drop as far down or push as hard to stand back up. Stick with an elongated bowl shape — it gives you a few extra inches of length, which feels more like a chair and less like a cramped perch.
Flush System and Water Use
You will see three main flush types: gravity-fed siphonic, pressure-assisted, and dual-flush. Gravity-fed siphonic (the most common) uses the weight of water in the tank to pull waste down the trapway. Dual-flush models let you choose a light flush for liquid (often 1.1 GPF — gallons per flush) and a full flush for solid waste (1.6 GPF). A single-flush model might run at 1.28 GPF, which is WaterSense certified and still powerful enough for most homes. Look for at least an 800-gram MaP score if you want reliable waste removal on a single flush.
One-Piece vs Two-Piece Construction
One-piece toilets have the tank and bowl molded as a single unit. That means fewer crevices for dust and grime to collect, and you have one smooth surface to wipe down. Two-piece toilets are the traditional setup — separate tank that bolts onto the bowl. They are usually lighter to carry up stairs and cheaper to buy, but the seam where tank meets bowl is a spot you will need to scrub. For an ADA toilet installed in a main-floor bathroom, a one-piece model is the cleaner, easier-to-maintain choice.

In‑Depth Reviews
1. TOTO Drake Two-Piece Elongated 1.6 GPF Universal Height TORNADO FLUSH Toilet
The gold-standard flusher that clears the bowl in a single swirl.
The TOTO Drake is among the most trusted names in toilets, and for good reason. It uses TORNADO FLUSH — a cleaning action that sends water spinning around the bowl in a circular pattern to wash the whole surface, not just a small jet stream. This means waste rarely sticks, and you need to scrub far less often. The ultra-smooth glaze coating (CEFIONTECT) adds to that effect by minimizing how much anything clings to the porcelain.
Beyond the cleaning performance, the Universal Height of the Drake meets the ADA requirement for easier sitting and standing. It uses a 1.6 GPF single flush (gallons per flush) with a wide 3-inch flush valve, so there is no guessing between buttons — one lever pull, and everything is gone. Buyers report that a single flush from this 1.6 GPF model outperforms three flushes of cheaper toilets. At 94 pounds (two-piece construction), while the HOROW one-piece weighs 99.2 pounds., you will still want a helper for the bowl, but the install is straightforward with the included hardware. You will need to buy the wax ring, flange bolts, and water supply line separately.
The Drake uses a standard 12-inch rough-in (the distance from the wall to the toilet drain) and has a left-hand trip lever. All internal parts are included, but you will need to buy a toilet seat separately. Compared to the Kohler Highline below, the TOTO delivers a noticeably more decisive flush thanks to the Tornado technology and the larger water surface that prevents debris from clinging.
What Makes It Stand Out
- TORNADO FLUSH fully washes the bowl with a circular swirl
- CEFIONTECT glaze minimizes waste sticking
- Universal Height is ADA compliant for easier sitting and standing
- 1.6 GPF wide 3-inch flush valve for strong single-flush performance
Watch Out For
- Wax ring, flange bolts, and water supply line not included
- Toilet seat not included — you need to buy one separately
- Heavy bowl (94 lb) requires two people to handle
Who it fits: Anyone who wants the most reliable flush on the market and does not mind buying a seat separately — perfect for a primary bathroom where performance matters most.
The only catch: You will need to purchase a wax ring and a soft-close seat before install, adding a trip to the hardware store.
2. TOTO Drake Transitional Two-Piece Elongated 1.28 GPF Universal Height TORNADO FLUSH Toilet
The same legendary Drake flush, trimmed to use less water per use.
If you want the same TORNADO FLUSH and CEFIONTECT glaze as the model above, but you want to cut your water usage, this is the version to get. It runs at 1.28 GPF (gallons per flush), which is WaterSense certified — meaning it uses 1.28 GPF and is WaterSense certified without sacrificing performance. Owners mention the 1.28 GPF flushes better than many 1.6 GPF toilets they have used in the past, thanks to the fully glazed 2-1/8-inch trapway and wide 3-inch flush valve.
The Universal Height on this model meets ADA requirements, so the seat sits at the same comfortable level as the 1.6 GPF Drake. It is a two-piece design weighing 96 pounds, making it a few pounds heavier than its sibling. The dual-action flush lever works like this: hold it for a full flush, or a quick flip gives you a smaller flush — a detail buyers had to figure out on their own, as no documentation in the box describes it. One reviewer praised how the pre-wet surface reduces cleaning and noted there is no bowl lip (the ridge inside the bowl where stains collect), so scrubbing is genuinely easier.
This model ships without a toilet seat, so factor that cost into your budget. It fits a 12-inch rough-in and works with a TOTO SoftClose seat or a WASHLET bidet seat if you want to upgrade later. Buyers strongly caution that Amazon packaging sometimes causes damage during shipping, so inspect the box carefully on arrival.
Water-saving powerhouse: This model uses 1.28 GPF, while the 1.6 GPF Drake uses 1.6 GPF. while maintaining the same Tornado Flush performance — the best choice for environmentally-conscious households.
The learning curve: The dual-action lever works differently depending on how you press it, and the box does not include instructions for that feature — you will need to experiment or watch a quick video.
Reach for this if: You want TOTO’s premium flush performance and care about water bills — the 1.28 GPF WaterSense certification saves water without a weak flush.
Look elsewhere if: You want a toilet that includes a seat in the box; you will need to buy one separately.
3. Kohler K-3999-0 Highline Comfort Height Two-Piece Elongated 1.28 GPF Toilet
A quiet, dependable workhorse from a brand you already trust.
The Kohler Highline delivers exactly what the name promises — a comfortable, chair-height seating position (the Comfort Height feature) that makes sitting and standing easier for most adults. It uses Kohler’s Class Five flushing technology, which is a gravity-fed siphonic system engineered to clear the bowl in a single flush at 1.28 GPF. Buyers describe the flush as quick and quiet, and one reviewer noted the chain was too long from the start but fixed it by moving a clip six links up.
This two-piece toilet weighs 93 pounds; the TOTO Drake options weigh 94 and 96 pounds., and the 3-bolt tank system makes the tank-to-bowl connection very stable during installation. One buyer — a 5-foot-tall woman — found the installation surprisingly easy thanks to that tank design. The dimensions are 29.75″D x 18.13″W x 31.25″H, which is The dimensions are 29.75″D x 18.13″W x 31.25″H, while the HOMLYLINK measures 29″D x 17″W x 34.5″H., so measure your bathroom carefully before buying. One thing to know: the Highline does not include a seat, so you will need to buy one separately.
A small number of buyers experienced an issue where the flush mechanism sounded like it was running on for a few seconds after the flush completed, though it did eventually shut off. The one-year limited warranty from Kohler covers defects, but some buyers found the Amazon return process frustrating if the bowl arrived cracked — Kohler did honor a replacement in that case, but the process took longer than expected.
Why Choose This One
- Comfort Height meets ADA requirements for easier sitting/standing
- Class Five flush is quiet and powerful at 1.28 GPF
- 3-bolt tank system makes installation stable and straightforward
Things To Consider
- No toilet seat included — remember to buy one
- Some reports of a “run on” sound after the flush completes
- Warranty process can be slow if you need a replacement bowl
Who this suits: Someone who wants a well-known brand with a proven, quiet flush and does not mind buying a seat separately — a solid mid-range choice for a guest or master bathroom.
The trade-off: The Class Five flush is effective, but the TOTO Drake above has a more thorough bowl-cleaning swirl that keeps stains at bay longer.
4. Gerber Viper Force Elongated Two-Piece Toilet
A compact, highly-rated toilet that includes a soft-close seat in the box.
Unlike the TOTO and Kohler picks above that require a separate seat purchase, the Gerber Viper Force comes with a ReadySet soft-close elongated seat that installs in seconds with no tools and removes fully for cleaning. It is a serious convenience win. This two-piece toilet uses a 1.28 GPF high-efficiency flush with Fluidmaster 400A fill and 3-inch flush valves (which deliver consistent, quiet refills) and a smooth glazed trapway to keep waste flowing. Customers note it flushes perfectly, has a good seat quality, and fits a small bathroom thanks to its compact elongated shape. One reviewer grinned about the “Scary Name, Great Toilet” — noting the “Viper” label is off-putting but the performance is solid.
At 78.2 pounds, the Gerber is the lightest toilet on this list — weighs 78.2 pounds; the HOROW T0338W weighs 99.2 pounds, and the HOMLYLINK weighs 86 pounds.. That makes it noticeably easier to move up stairs and position during installation. The dimensions are 29.5″D x 16.5″W x 31.75″H, making it similar in depth to the Kohler Highline but slightly narrower. The oval shape fits compact spaces well, and the chair height meets ADA standards. One buyer mentioned the boxed total weight is over 100 pounds, so you still might want a hand getting it inside.
Buyers consistently call it an excellent value, and it was top-rated by Consumer Reports. The Fluidmaster components are standard parts that are easy to find if you ever need a replacement fill valve or flapper. This is the most affordable option in the mid-range group, and you get a soft-close seat included — something the premium TOTO and Kohler models do not offer at a higher price.
Complete package: The included ReadySet soft-close seat saves you a separate purchase and installs without tools — a real advantage over the TOTO and Kohler models that need a separate seat.
Compact and light: At 78.2 pounds, this is the Gerber weighs 78.2 pounds, so it is easier to carry and install solo compared to the 99-pound HOROW or 116-pound EPLO.
Best for: Anyone who wants a complete toilet with a soft-close seat at a great price point — one-box purchase, no extra trips to the store. Ideal for a guest bathroom or a tight budget without cutting quality.
skip it if: You prefer the smooth look of a one-piece toilet or want a more powerful flush than this efficient 1.28 GPF design delivers.
5. DeerValley Elongated Toilet with Comfort ADA Seat Height, One Piece
A modern one-piece that one buyer installed solo in under 25 minutes.
The DeerValley DV-1F026Pro is a one-piece, skirted toilet with an ADA-compliant seat height of 17 3/8 inches and a dual flush system at 1.1/1.6 GPF. The skirted design means the sides are smooth — no exposed trapway in the back, so you do not have a horizontal shelf that collects dust and grime. The high-temperature calcined ceramic construction gives it a strong texture that resists scratches and corrosion. With a MaP score of 800 grams, the dual flush handles solid waste without needing a second flush.
One owner reported the toilet arrived in a big box and they installed it themselves in under 25 minutes — a fast turnaround made easier by the side access ports that hide the bolts and give you room to tighten them. Weighs 95 pounds; the TOTO Drake weighs 94 pounds, but this is a one-piece., so there is no seam to clean. The dimensions are 27.95″D x 14.17″W x 26.77″H — the narrowest width on this list, which is handy for tight bathrooms. The self-cleaning glazed surface is mentioned by the manufacturer as preventing dirt buildup, and buyers confirm the smooth sides make cleaning noticeably easier.
Buyers also mention the internal parts are integrated into the one-piece design, which means if something fails (like the flush valve), it is harder to repair than a standard two-piece where you can swap individual components. A few users highly recommend repositioning the floor water supply valve before installation, as the skirted design can block access to it once the toilet is set. Overall, it is a clean, modern look at a mid-range price point with strong reviews.
What Works Well
- Skirted one-piece design is easy to clean with no exposed trapway
- Narrow 14.17-inch width fits tight bathroom spaces
- Side access ports for hidden bolts make installation simpler
Potential Drawbacks
- Integrated internal parts are harder to repair if something breaks
- Floor water supply valve may need repositioning before install
- 95-pound one-piece is awkward to carry alone
Reach for this if: You want a modern, easy-to-clean one-piece toilet with a skirted profile and an 800-gram MaP dual flush — a very strong choice for a compact master bathroom or powder room.
Consider the catch: If the internal flush components fail, repairs are more complex than with the two-piece Gerber or TOTO models where you can replace parts individually.
6. HOROW T0338W Compact One Piece Toilet, ADA Chair Height 17.3″
A one-piece that sneaks ADA comfort into a space less than 27 inches deep.
The HOROW T0338W is built for bathrooms where every inch counts. Measuring just 26.6″D x 15″W x 26″H, it is the shortest and narrowest one-piece ADA toilet on this list — several inches shallower than the 29-inch-deep HOMLYLINK and Gerber models. The 17.3-inch seat height meets ADA requirements, and the elongated bowl gives you the legroom you need without extending too far into the room. This model offers both a 10-inch and 12-inch rough-in version, so it can work in older homes with non-standard plumbing. Reviewers point out they have owned one for about three years and bought a second for a different bathroom, citing no problems. Another reviewer called it a great option for tall and big people who could not afford a TOTO.
The dual flush system runs at 1.1/1.6 GPF with siphon flushing and a fully-glazed 2-inch trapway. Some reviewers — as noted in our data — found the flush force to be weak for significant solid waste, saying it is only good for minimal waste. The included soft-close seat is a nice touch that screws into place, but several buyers said the seat cover mechanism is flimsy and the seat itself closes very slowly (over 30 seconds).
Installation is a bit quirky: you must connect the water line before setting the toilet in place, and the side access hand holes are small, making it tricky to tighten the flange bolts. The back of the toilet has a carve-out that helps it fit near a wall-mounted water supply, which is a thoughtful design detail for tight spaces. HOROW offers lifetime after-sales support and a 1-year limited warranty with customer response within 12 hours.
Tight-space specialist: At 26.6 inches deep, this toilet fits where the 29-inch models (HOMLYLINK, Gerber, Kohler) simply will not — ideal for a half-bath or small guest toilet.
Install quirks: You have to connect the water line before you set the toilet, and the tiny hand holes make centering on the flange bolts a real puzzle — read the instructions carefully.
Who should pick this: Someone with a small bathroom depth (under 28 inches) who still wants a one-piece, ADA-compliant toilet. The compact footprint is the main reason to choose it over the larger DeerValley.
Who should not: Anyone who needs a powerful flush for heavy use — the siphon flush on this model is rated by buyers as weaker than the TOTO Tornado or the Kohler Class Five.
7. HOMLYLINK 19 Inch ADA Elongated Tall Toilet for Seniors
The tallest seat on the list — 20 inches — built for easier transfers.
With a seat height of 20 inches from the floor, the HOMLYLINK is the tallest ADA toilet in this guide. The HOMLYLINK seat height is 20 inches, while the HOROW is 17.3 inches. for someone with limited hip or knee mobility — you barely have to squat to sit, and standing back up requires very little pushing. The elongated bowl at 18.5 inches gives you comfortable thigh support. The manufacturer explicitly targets this toilet at seniors, handicapped individuals, tall people, pregnant women, and recovering patients. One buyer says they bought it for the third time — a repeat purchase for the in-laws’ bathroom — and the 78-year-old owners were thankful for the additional height.
The flushing system uses a 360° jet siphon design with hidden water holes around the bowl rim, paired with a dual flush at 1.1/1.6 GPF. The 360° jets push water around the entire bowl surface rather than just a single stream, which helps prevent lingering odors and stains. The glaze is described as having an ultra-low water absorption rate, so the porcelain resists yellowing over years of use. The toilet includes a soft-close seat, wax ring, and all installation hardware in one package — so there are no extra trips to the store, unlike the TOTO and Kohler models. At 86 pounds, it is the lightest two-piece toilet here, and about 13 pounds lighter than the HOROW.
There is a significant warning from one buyer who ordered two toilets expecting an elongated shape based on the product listing photos but received round bowls instead. They had to deal with a third-party seller (Homlylink) and Amazon blaming each other for the return, and the return shipping cost was ~ for a purchase. This was a single negative experience, but note that this product is sold by a third-party seller through Amazon, and the return process can be difficult if the wrong item arrives. Make sure the listing explicitly says “elongated” in the title and in your order confirmation.
Why It Stands Out
- 20-inch seat height — the tallest in this guide, best for seniors and anyone with mobility issues
- Includes soft-close seat, wax ring, and all hardware in one package
- 360° jet siphon flush cleans the entire bowl surface
Risks To Know
- One buyer received round bowls instead of elongated — verify the listing before ordering
- Sold through a third-party seller, making returns or exchanges difficult if something goes wrong
- Flush power is adequate but not as strong as the TOTO Tornado or Kohler Class Five
Reach for this if: Seat height is your top priority — this is the tallest ADA-compliant toilet on the market, and it arrives with everything you need to install it in one box.
Be cautious if: You are ordering from a third-party seller and need confidence about returns — the TOTO, Kohler, or Gerber models sold directly by Amazon or well-known distributors may be a safer bet.
8. CANEST Smart Toilet, Smart Toilet with Bidet Built in, ADA Comfort Height
A smart bidet toilet that delivers heated comfort while staying affordable.
The CANEST TC-100GE is a complete all-in-one smart toilet with a built-in bidet, designed for ADA comfort height. It includes an intelligent heated seat, warm water cleansing with multiple wash modes, an air dryer, soft night lighting, and automatic deodorization. A foot sensor controls the seat and flush, so you never have to touch the toilet with your hands — a feature buyers mention is convenient and clean. The MaP flushing system is rated at 1000 grams, which matches the highest MaP score in this guide alongside the EPLO U8MAX. The toilet is a one-piece, elongated design with a tank built in (not a tankless model), so it works reliably even during a power outage with a backup flush function.
At 95 pounds, the CANEST is about the same weight as the DeerValley and TOTO Drake models. The dimensions are 26.5″D x 16.8″W x 18.7″H — the height here is just the bowl and seat (18.7 inches from floor to the top of the bowl), which is within ADA comfort height range. Shoppers say the heated seat is very comfortable during cold weather, and the warm water bidet and air dryer work well. One reviewer described it as a great first step in updating an older bathroom, noting the modern one-piece design fits smaller bathrooms. The digital display is easy to use, and the overall performance feels reliable and modern.
The catch is that this model focuses on essential smart features — it does not include an automatic lid/seat opening or closing, which you would get on the more expensive CANEST models (TC-200GE NEW or TC-200BG). The lid has soft-close, but you need to lower it by hand. If you want automatic open/close, the EPLO U8MAX below is the upgrade path. A few buyers mentioned the remote control is intuitive, and the night light is a nice touch for late-night bathroom visits.
Smart features where they matter: Heated seat, warm water bidet, foot sensor, and air dryer — this covers the most useful daily upgrades without the premium price of auto-opening lids.
What you give up: No automatic lid opening or closing — you still need to lift and lower the seat by hand. If that is a dealbreaker, look at the EPLO below.
Who this fits: Someone who wants a bidet, heated seat, and hands-free foot operation but is okay with a manual lid — especially suitable for a primary bathroom where comfort and hygiene are the top priorities.
pass on it if: You want the full smart experience with auto-open lid and automatic closing — that requires the next tier of smart toilets like the EPLO U8MAX.
9. EPLO Smart Toilet Bidet with Auto Open Close, Foam Dispenser, ADA Comfort Height
A smart toilet with a foam dispenser that keeps the bowl spotless between washes.
The EPLO U8MAX is the most feature-packed toilet in this guide. Its standout feature is the Foam Shield — a dispenser that creates a protective foam layer on the water surface before each use, which prevents splashback and stops waste from sticking to the bowl. Combined with a MaP flush score of 1000 grams (matching the CANEST), the foam means the toilet stays noticeably cleaner with less scrubbing. Other smart features include auto open/close of the lid (activated by approaching the toilet), a heated seat, foot sensor controls, auto flush, a moving air dryer with adjustable temperature and wind speed, and a dual LED display. The bidet offers front wash, rear wash, and oscillating wash modes with adjustable water pressure, spray position, and temperature.
The ADA comfort height is stated as 17.41 inches from floor to seat (meeting ADA Standard 117.1), making it suitable for seniors and those with limited mobility. The dimensions are 27.63″D x 16.14″W x 19.68″H — a compact footprint for a smart toilet with a built-in tank. At 116 pounds, the EPLO is the heaviest; the CANEST weighs 95 pounds, and the Gerber Viper Force weighs 78.2 pounds. — so you will need two people to carry it. The tank is built-in, and it includes a three-way angle valve, sealing flange, mounting kit, and remote control. The dual flush lets you choose 1.6 GPF full flush or 1.1 GPF half flush, and four-season temperature sensing automatically adjusts the heated seat and warm water to ambient conditions.
Buyers describe the EPLO as a luxury and performance upgrade over seat-only bidets. One customer observed the foam feature works well, the toilet is quiet, and the install (DIY ~20 minutes) was straightforward thanks to the included GFCI plug and battery backup. Another said it works well even in a low water pressure home where other bidet toilets failed. The overall consensus is that the build quality is solid, the features are comprehensive, and the customer service is excellent. If you want the highest-end smart toilet with the most features, this is it.
Luxury Features
- Foam Shield dispenser prevents splashback and keeps bowl clean
- Auto open/close lid with foot sensor for a fully hands-free experience
- 1000g MaP flush is powerful, quiet, and clog-free
- Moving air dryer with adjustable temperature, wind speed, and position
Cost of Luxury
- 116 pounds — very heavy; definitely need two people to carry and install
- Significantly more expensive than all other toilets in this guide
- More complex electronics mean more potential failure points over time
Best for: Someone who wants the ultimate hands-free smart toilet experience with a bidet, foam dispenser, and auto-open lid — perfect for a master bathroom where luxury is the goal.
The trade-off: It costs more than all other options combined, weighs 116 pounds, and the advanced electronics could require service down the road that a simple gravity-flush toilet would not.
Understanding the Specs
Seat Height and ADA Compliance
The ADA standard for a toilet seat height is 17 to 19 inches from the floor to the top of the seat. That is 2 to 4 inches higher than a standard toilet (around 15 inches). The higher seat reduces how much you have to bend your knees and hips, which in turn takes stress off your lower back and knee joints. All nine toilets in this guide meet that requirement. The HOMLYLINK 19-inch offers the tallest seat, while the HOROW and DeerValley are at the lower end of the range at 17.3 and 17.375 inches respectively. If the tallest possible seat is your priority, aim for the 19-inch models.
MaP Flush Score
MaP stands for “Maximum Performance” — it is the industry standard test for measuring how much waste a toilet can clear in a single flush. The score is given in grams. A MaP score of 350 grams is the minimum for a passing grade, but a well-performing ADA toilet should hit at least 800 grams. The CANEST and the EPLO U8MAX both have a 1000-gram MaP rating, which is the highest in this guide and means they can clear the maximum test load easily. The TOTO Drake uses Tornado Flush technology instead of a MaP score, but its performance is equally strong in real-world use.

Final Thoughts: The Verdict
For most buyers, the ada toilet winner is the TOTO Drake CST776CSFG because of its Tornado Flush technology that keeps the bowl cleaner longer, its Universal Height that complies with ADA standards, and its reputation for decades of reliable performance. If you want a complete package that includes a soft-close seat and costs less, grab the Gerber Viper Force. And for the ultimate hands-free smart experience with a foam dispenser and auto-open lid, the standout is the EPLO U8MAX.
