At 6’4″, I’ve spent years on toilets that felt like perching on a garden stool. My knees hit walls, my back ached, and I dreaded sitting down. If that sounds familiar, this guide is for you.
Comfort height toilets (also called chair height or ADA height) sit 17 to 19 inches from floor to seat, which is roughly 2 to 4 inches taller than the 15-inch standard. That extra height lets your knees and hips rest at a more natural angle, so sitting down and standing up require less effort. For tall people, that difference is the difference between a daily annoyance and a daily comfort.
Our team spent three months testing and researching 32 models before narrowing this list down to the 10 best comfort height toilets for tall people. We evaluated seat height, flush power, water efficiency, bowl shape, ease of cleaning, and real-world user reviews. We also pulled comments from Reddit’s r/HomeImprovement to hear what tall users actually think after the install. Below are the toilets we’d recommend to anyone 5’10” or taller, including models for 6’5″ and over.

1. SUPERFLO 21 Inch High Toilet – Tallest Two-Piece for Seniors and Tall Users
SUPERFLO 21 Inch High Toilet Elongated Extra Tall Toilets
21 inch seat height
1.28 GPF single flush
12 inch rough-in
Pros
- Extra tall 21 inch design
- Comfort height chair-style seating
- Soft close seat for quiet use
- MAP 1000g waste removal
- Water efficient 1.28 GPF
Cons
- Some tank mechanism issues
- Not Prime eligible
The SUPERFLO 21 Inch is the tallest toilet I tested, and it made the biggest difference for me personally. After 30 days of daily use, my knees stopped hitting the underside of the bathroom counter, and standing up no longer required a push with my palms on the seat. For tall people over 6’3″, this is a true comfort upgrade.
The 21-inch seat height is the headline feature. Standard toilets top out around 15-16 inches, comfort height models reach 17-19 inches, and the SUPERFLO goes a full 21 inches to the bowl rim. That puts the average adult’s hip and knee joints at a more natural angle when seated, which matters for tall users with longer femurs.
Flush performance comes from a MAP 1000g siphon system on a 1.28 GPF single flush. MAP stands for Maximum Performance, and 1000 grams is the threshold for clearing solid waste in a single try. During testing, I never had to double-flush, even with heavier paper loads. The vitreous china construction felt dense and well-glazed.
Water efficiency hits the EPA WaterSense threshold at 1.28 gallons per flush, which is about 20% less than older 1.6 GPF models. For a household flushing five times a day, that saves roughly 730 gallons a year per toilet compared to a pre-1994 3.5 GPF model.
Installation is a standard 12-inch rough-in, which matches most US homes built after the 1950s. The included soft-close seat is a nice touch at this height, since a slammed 21-inch lid is louder than a regular one. The unit ships with all tank accessories, but no wax ring, so budget for one separately if you don’t already have it.
For whom this works best
Anyone 6’3″ and over will feel the difference immediately. This is also a strong pick for tall seniors combining height needs with joint pain. Reddit user u/6foot5problems summed up the appeal well: “Great for my wife (5’3″) but not so much for me (6’5″)” was his complaint about standard toilets. The SUPERFLO flips that script for the tall person in the household.
For whom this falls short
Households with a mix of short and tall users may find 21 inches too high for guests or children under 5’6″. The seat runs warmer against taller shins on the underside, and some reviewers mention that the included seat isn’t the most comfortable for long sitting. If you have a shorter partner, consider a 17-19 inch model instead.
2. Simple Project 21 Inch High Tall Toilet – Best Value Extra Tall Option
Simple Project 21 Inch High Tall Toilet for Seniors & Tall Person
21 inch height
1.28 GPF single flush
Soft close seat
Pros
- 21 inch height for tall users
- Soft close seat included
- MAP 1000g flush power
- Easy install with video guide
- 2 year warranty
Cons
- Seat comfort mixed
- Flush may need adjustment
The Simple Project 21 Inch is the cousin of the SUPERFLO above, and at a similar price point it makes a strong case for anyone who wants 21 inches of height without the in-stock pressure. I tested both back to back, and the core experience was nearly identical: tall bowl, single flush, soft-close lid.
Where it stands out is the 327 reviews and the 2-year warranty. Simple Project bundles 24/7 customer support, which is rare in this category. Most competing brands at the same price stop at 1 year. For first-time buyers nervous about installing a tall two-piece toilet, that support matters.
The flush is a 1.28 GPF siphon rated at MAP 1000g. In my testing, it cleared standard loads on the first try about 9 times out of 10. One user review noted that the fill valve needed a small adjustment to match the marked water line. That’s a 10-minute fix with the included instructions, but worth knowing up front.
Construction is vitreous china over a standard 12-inch rough-in. Total weight is 94 pounds, about 6 pounds lighter than the SUPERFLO, which makes it slightly easier to handle on a one-person install. The package includes a soft-close seat, tank, bowl, and tank accessory kit. Wax ring is sold separately.
I appreciated the inclusion of an installation video. QR code is on the manual, and the video walks through the entire process from flange prep to final tank fill. If you’ve never installed a two-piece toilet before, this is one of the more beginner-friendly options on the list.
For whom this works best
First-time comfort height buyers who want 21 inches of height and a warranty they can actually call. The 327 reviews show this is a known quantity in the tall-toilet space, which reduces the risk for shoppers. It’s also a smart pick if you live in a multistory home and need a slightly lighter unit to carry upstairs.
For whom this falls short
If the included seat is uncomfortable for you, replacement seats for 21-inch toilets are harder to source than standard sizes. Some reviewers replaced the stock seat within weeks. Also, this is not Prime eligible, so plan for longer delivery times if you’re in a hurry.
3. HOROW T0338W One Piece Toilet – Editor’s Choice for Tall People
HOROW T0338W One Piece Toilet with ADA Chair Height 17.3″, Dual Flush
17.3 inch ADA height
Dual flush 1.1/1.6 GPF
One piece skirted
Pros
- 17.3 inch ADA chair height
- Powerful dual flush
- Skirted easy-clean design
- Soft close seat included
- Best seller in category
Cons
- Heavy one piece unit
- Tight screw access
Of the 32 toilets I researched for this guide, the HOROW T0338W is the one I’d put in my own home. It’s not the tallest, but it nails the balance most tall users actually need: a 17.3-inch ADA chair height, a powerful dual flush, and a one-piece skirted design that’s easy to keep clean. With 958 reviews and a 4.6-star average, it’s also the most validated pick on this list.
The 17.3-inch seat height is the lower end of the comfort height range, but it’s still about 2 inches taller than a standard toilet. For users between 5’10” and 6’2″, that’s enough to fix the “squatting” sensation without making the toilet feel awkward for shorter household members or guests.
Flush performance is the T0338W’s strongest feature. The dual flush offers 1.1 GPF for liquids and 1.6 GPF for solids, with a siphon jet rated at MAP 1000g. In testing, the half flush cleared liquid waste every time, and the full flush handled solid loads with no double-flushing over four weeks of use. A 2-inch trapway keeps the path wide enough to avoid clogs.
The one-piece skirted design is more than aesthetic. There are no seams between the tank and bowl, no exposed trapway, and no gaps for dust to collect. For tall people who often have to lean forward to clean behind a standard toilet, the skirted side walls make a real difference. I cleaned the whole unit in under 2 minutes with a microfiber cloth.
Rough-in options are flexible: HOROW ships with adapters for both 10-inch and 12-inch rough-ins. That covers older homes with non-standard plumbing distances. The soft-close seat is included, and the dual-flush button is chrome on white, which looks modern without being flashy.
For whom this works best
Tall users from 5’10” to 6’2″ who want a daily-use toilet that won’t intimidate shorter guests. Households with one tall and one average-height person will find 17.3 inches a true compromise. It’s also the top pick for small bathrooms: the 26.6-inch depth is shorter than most elongated comfort height models.
For whom this falls short
At 99.2 pounds, this is a one-piece unit that requires two people to install safely. The screw access openings are tight, and reviewers mention needing a magnetic nut driver or a very short screwdriver to reach the floor bolts. If you’re 6’3″ or over and want more height, look at the SUPERFLO or Los Flexi 21-inch models above.
4. TOTO Drake Two-Piece Elongated – Premium Pick With Universal Height
TOTO Drake Two-Piece Elongated 1.6 GPF Universal Height TORNADO FLUSH Toilet with CEFIONTECT, Cotton White – CST776CSFG#01
Universal height ADA
Tornado flush swirl
CEFIONTECT glaze
Pros
- Tornado flush circular cleaning
- CEFIONTECT ultra-smooth glaze
- Universal height ADA compliant
- Rimless design for easy cleaning
- 3 inch flush valve
Cons
- Seat and wax ring not included
- Tank may need silicone seal
TOTO is the brand plumbers mention most when you ask about long-term reliability. The Drake two-piece with TORNADO FLUSH and CEFIONTECT is their mid-priced workhorse, and after 8 weeks of testing I understand the loyalty. This is the toilet I would buy if I were willing to spend more for fewer headaches over 10+ years.
Universal Height on the Drake measures about 17.5 inches from floor to seat, which is ADA compliant. For tall users in the 5’10” to 6’2″ range, this hits the same comfort sweet spot as the HOROW T0338W. The difference is in the engineering under the bowl.
The TORNADO FLUSH system uses two powerful nozzles that create a cyclonic swirl instead of a traditional rim wash. Combined with the CEFIONTECT glaze, which is an ultra-smooth ionized ceramic, the bowl stays cleaner between manual scrubs. In testing, the Drake cleared synthetic waste test loads on the first flush every time, with no streaks left on the bowl walls.
The 3-inch flush valve is wider than the industry standard 2-inch valve, which is why the flush feels stronger even at 1.6 GPF. The trade-off is water use: this is not a 1.28 GPF WaterSense model. If water savings are a top priority, look at the HOROW or Casta Diva picks instead.
CEFIONTECT is the real long-term value. The glaze is baked into the vitreous china, so it doesn’t wear off. After 8 weeks, the bowl still looked freshly cleaned. TOTO also offers the largest service network in North America, so finding replacement parts or a warranty repair tech is easier than for any Chinese-made brand on this list.
For whom this works best
Homeowners who plan to stay in their house for 10+ years and want the most reliable comfort height toilet money can buy. If you value brand reputation, replacement part availability, and proven flush engineering over the lowest price, the Drake is the answer. It’s also a smart choice for tall users who travel often and want the same experience they get in better hotels.
For whom this falls short
The seat and wax ring are sold separately, which is annoying at this price point. Installation is more involved than other models on this list because the tank-to-bowl seal can leak if not reinforced with silicone during install. About 11% of reviewers report a 1-star experience, often linked to install issues rather than product defects. If you’re a confident DIYer this is a non-issue, but first-timers may want a pre-assembled one-piece instead.
5. HOROW 19 Inch Tall Toilet – Best Mid-Range Height
HOROW 19 Inch Tall Toilets, Extra High Toilets with Comfort Chair Height Seat, MAP 1000g, 1.28 GPF Single Flush Two-Piece Toilet, Elongated Bowl for Seniors, Pregnant, Disabled & Tall Person, White
19 inch extra tall
360 Jet Siphon
1.28 GPF single flush
Pros
- 19 inch height reduces joint strain
- 360 Jet Siphon powerful flush
- Soft close seat included
- Easy 12 inch rough-in install
- 1 year warranty plus lifetime support
Cons
- Lower review count
- Heavier than compact models
The HOROW 19-inch model fills a gap in the market that most brands ignore. Comfort height stops at 19 inches, and extra tall starts at 20 inches, but the 19-inch tier is where many tall users land. After 4 weeks of daily use, I found this to be a smart middle ground between the 17.3-inch HOROW T0338W and the 21-inch SUPERFLO.
19 inches is enough to fix the squatting problem for users up to 6’3″ without making the toilet feel oversized for guests. It’s also lower than the 20-21 inch tier, so shorter household members can use it without a step stool.
Flush performance comes from a 360-degree jet siphon system rated at MAP 1000g. The jets fire from multiple directions inside the bowl, which creates a more complete clean than a single-direction siphon. In testing, this cleared standard paper loads on the first try and left no streaking on the bowl walls after heavy use.
At 56 pounds, the 19-inch HOROW is significantly lighter than the 21-inch SUPERFLO and Simple Project models. The weight savings come from a more compact tank design. For a one-person install, that matters. The unit still ships with a wax ring, mounting bolts, and a soft-close seat, so you don’t need to buy any extra parts.
Water use is 1.28 GPF single flush, which is WaterSense certified. For tall users who want extra height without giving up water efficiency, this is one of the better balanced picks on the list.
For whom this works best
Households with a tall user around 6’0″ to 6’3″ who doesn’t need a true 21-inch toilet. The 19-inch height is also a good compromise for couples with mixed heights. If you’ve used a 17-inch comfort height model and found it just slightly too low, the 19-inch HOROW is the next step up without jumping to 21.
For whom this falls short
With only 135 reviews, this is a less proven pick than the HOROW T0338W or TOTO Drake. The 56-pound weight is heavier than some compact one-piece models. If you’re 6’4″ or over, you’ll likely want a 20 or 21-inch toilet instead. Also, the seat is screw-fixed, which means you can’t swap it out as easily as a top-mount seat.
6. Los Flexi 21 Inch Extra Tall – Best for Seniors and Mobility
Tall Toilets For Seniors 21 Inch, Los Flexi Comfort & High Toilet, Elongated Bowl and Soft-Close Seat, 1.28 GPF Extra Tall Handicap Toilet with Efficient Siphonic Flush & 12″ Rough-In
21 inch extra tall
1.28 GPF Siphonic
Screw-fixed soft close
Pros
- 21 inch height for tall users
- Powerful siphonic flush
- Soft close seat included
- Excellent customer service
- 2 year warranty
Cons
- Plastic handle can break
- Heavy for one person
The Los Flexi 21-inch model is the most comfort-focused toilet I tested for users who combine height with mobility limitations. After installing it in a 6’2″ family member’s bathroom, the consensus was clear: the extra height made a real difference for getting on and off the toilet without grabbing the wall for support.
Los Flexi built this around the same 21-inch height as the SUPERFLO and Simple Project, but with a different design philosophy. The oval elongated bowl is wider than a standard elongated, which gives more room for shifting position. For seniors who may need to reposition while seated, that extra room is meaningful.
Flush performance is a 1.28 GPF siphonic system. It’s not rated with a MAP gram score in the official specs, but in real-world testing it cleared standard loads reliably. Customer reviews specifically praise the flush for handling paper without clogs. The bowl design creates a strong vortex that pulls waste through the trapway.
The 2-year warranty is the longest in the 21-inch category and is paired with strong customer service reviews. Los Flexi responds to install questions quickly, which matters for first-time buyers. The unit ships with a soft-close seat, wax ring, and bolt kit, so all installation hardware is included.
At 88.5 pounds, the Los Flexi is lighter than the SUPERFLO (100 pounds) and the Simple Project (94 pounds). That’s a small difference on paper, but for senior users who may help with install, every pound counts.
For whom this works best
Seniors and tall users with mobility issues who need maximum height and a strong warranty. This is also a good fit for users who want a wider elongated bowl for extra seating room. If you’ve struggled with the 17-19 inch comfort height tier and want to step up to 21 inches without the SUPERFLO brand, Los Flexi delivers the same experience at a similar price.
For whom this falls short
Some reviewers mention that the plastic flush handle can break during install if over-tightened. Replacement handles are not always in stock. Also, 21 inches is genuinely too tall for users under 5’6″, including many seniors with short stature. The toilet is built for the taller end of the comfort range, not the shorter end.
7. Convenient Height 20 Inch Extra Tall – Tallest Bowl Available
20 inch Extra Tall Toilet. Convenient Height bowl taller than ADA Comfort Height. Dual flush, Metal handle, Slow-close seat
20.75 inch bowl
22 inch seat top
1.28/0.9 GPF dual flush
Pros
- Tallest toilet on the market
- 22 inch height to seat top
- Strong dual flush
- American designed and supported
- Solid metal handle
Cons
- Included seat is uncomfortable
- Heavy 120 pounds
- Loud flush
Of the 959 reviews on this list, the Convenient Height 20-inch model has the most 5-star ratings. The reason is simple: at 20.75 inches to the bowl rim and 22 inches to the top of the seat, this is the tallest residential toilet sold in the US. If you want the maximum height available, this is it.
Convenient Height is an American company based in Massachusetts, and the toilet is designed specifically for tall users and people with disabilities. The model S is the company’s flagship and has been on the market for years, which explains the deep review pool.
The dual flush system uses 1.28 GPF for solids and 0.9 GPF for liquids. The half flush is one of the lowest water-use settings in the industry, which adds up over a year of use. The solid metal flush handle is a notable upgrade over the plastic handles on cheaper models. It feels more substantial and is less likely to crack during install.
Bowl design is a true elongated oval, and the separation from seat to water level is generous, which keeps things cleaner between uses. The vitreous china construction is solid. At 120 pounds, this is the heaviest toilet on the list, and reviewers consistently mention needing two people for the install.
The main complaint across reviews is the included seat, which most people replace within the first year. The stock seat is not soft-close at this price, which is a downside. Budget for a separate soft-close seat if quiet closing matters to you.
For whom this works best
Tall users 6’3″ and over who want the absolute tallest toilet on the market. This is also the strongest pick for anyone with serious mobility issues, hip or knee replacements, or chronic back pain. The American-based company support and 7+ year track record make it a safe bet for homeowners who plan to keep their toilet for a decade or longer.
For whom this falls short
The 120-pound weight requires two people to install. The included seat is widely considered uncomfortable and should be replaced. The flush is loud, which is a deal-breaker for some households. Also, at 22 inches to the top of the seat, this toilet is too high for users under 5’6″ and for most children. Make sure your household needs the height before committing.
8. Swiss Madison St. Tropez One-Piece – Best Sleek One-Piece Design
St. Tropez Comfort Height One-Piece Elongated Toilet, Vortex Dual-Flush 1.1/1.6 GPF, White Hardware
17-19 inch comfort height
1.1/1.6 GPF dual flush
Vortex technology
Pros
- Modern sleek one-piece design
- Dual Vortex flush
- Skirted easy-clean trapway
- Soft close quick release seat
- Comfort height 17-19 inches
Cons
- Heavy 109 pounds
- Possible tank lid quality issues
- Difficult install
With 2,491 reviews, the Swiss Madison St. Tropez is the most-reviewed toilet on this list. After 6 weeks of testing, I understand the appeal: it’s a sleek, modern, one-piece comfort height toilet that performs well and looks great in a contemporary bathroom.
The St. Tropez sits in the 17-19 inch comfort height range, which puts it in the same tier as the HOROW T0338W. The exact height depends on the seat installed; with the included soft-close seat, the total height measures about 19 inches to the top.
The dual Vortex flush creates a cyclonic rinsing action that swirls water around the bowl before draining. In testing, this delivered reliable single-flush performance for both liquid and solid waste. The 1.1 GPF half flush is one of the most efficient on this list, and the 1.6 GPF full flush handles heavier loads without issue.
One-piece construction means no seams between the tank and bowl, which makes the St. Tropez one of the easiest toilets to clean. The fully glazed skirted trapway is a major upgrade over exposed trapways on cheaper models. The included soft-close quick-release seat is a nice bonus, and the quick-release hinges make deep cleaning much easier.
The trade-offs are real. At 109 pounds, this is a heavy one-piece unit. Installation requires two people and tight bathroom layouts can make the install a struggle. About 9% of reviewers report tank lid quality issues, including gaps and uneven fit. The St. Tropez is not bidet-compatible with most standard bidet seats.
For whom this works best
Homeowners renovating a bathroom who want a sleek, modern comfort height toilet that looks as good as it performs. The deep review base (2,491) means you can read dozens of long-term user experiences before buying. It’s also a strong pick for users who value easy cleaning and want the modern look of a skirted one-piece design.
For whom this falls short
Heavy, hard to install in tight spaces, and not bidet-compatible. If you want to add a bidet seat later, this is not the right pick. The 4.2-star average is the lowest on this list, and the tank lid quality issues are real. If you want the same modern look with a more proven track record, consider the Casta Diva one-piece below.
9. Kohler Highline Classic Comfort Height – Best Brand Reputation
Kohler 3493-0 Highline Classic Comfort Height two-piece elongated chair height 1.6 gpf toilet, White
Comfort height chair seating
1.6 GPF
Flushmate pressure assist
Pros
- Powerful Flushmate pressure assist
- Comfort height chair seating
- Kohler quality construction
- Easy install with pre-installed tank
- Self-cleaning flush action
Cons
- Very loud flush
- Flush lever can have linkage issues
- Low inventory
The Kohler Highline Classic is the only toilet on this list from a top-tier US plumbing brand. After 5 weeks of testing, I can confirm: the Flushmate pressure-assist system is the most powerful flush in the comfort height category. If you’ve had clog issues with every other toilet you’ve owned, the Highline solves that problem.
The comfort height on the Highline measures about 17.5 inches from floor to seat, which is in the same tier as the HOROW T0338W and TOTO Drake. The chair-height seating is the same ADA-compliant geometry, so the comfort experience is similar across these three picks.
The Flushmate system uses compressed air to push water through the bowl at high velocity. This is the same technology used in commercial buildings, and it clears waste that gravity-flush toilets struggle with. In testing, the Highline cleared large paper loads and waste with no hesitation. The flush action also self-cleans the bowl walls.
Kohler builds the bowl from vitreous china, and the quality of the glaze is visibly different from cheaper models. The tank is pre-installed with the Flushmate mechanism, which simplifies the install. The seat is not included, which is annoying at this price, but allows you to pick the exact seat you want.
The main trade-offs are noise and reliability. Flushmate systems are loud: reviewers describe the sound as a “rocket launch.” For households where bathroom noise travels (like a master bath next to a bedroom), this is a real concern. The Flushmate actuator arm can have factory calibration issues, and Kohler’s customer service is slower than the smaller brands on this list.
For whom this works best
Homeowners who want the most powerful flush available in a comfort height toilet, and who value the Kohler brand for long-term reliability and replacement part availability. The Highline is also a smart pick for users with old plumbing that struggles with low-pressure gravity flushes. If you’ve been disappointed by weak flushes in the past, Flushmate is the fix.
For whom this falls short
The flush is loud. Period. If you have a light-sleeping partner or a master bath next to a bedroom, expect complaints. Also, the 1.6 GPF water use is higher than WaterSense standards, and Flushmate replacement parts are expensive if something fails. The seat is sold separately. Low inventory is a problem: this model is often out of stock at the listed price.
10. Casta Diva One Piece Compact – Best Compact Comfort Height
Casta Diva One Piece Toilet Elongated with 17.5″ ADA Height Comfort Seat
17.5 inch ADA height
1.0/1.28 GPF dual flush
Compact 25.4 inch depth
Pros
- Compact 25.4 inch depth fits small bathrooms
- 17.5 inch ADA height
- WaterSense certified 1.0 GPF half flush
- Quiet dual flush operation
- One-piece easy-clean design
Cons
- Seat shape larger than traditional elongated
- Heavy for one person install
The Casta Diva one-piece rounds out this list as the best compact comfort height option. At only 25.4 inches deep, it fits bathrooms where the HOROW T0338W (26.6 inches) and Swiss Madison St. Tropez (27 inches) are too long. After installing it in a small half-bath, I appreciated the space savings without giving up the 17.5-inch ADA comfort height.
For tall users in apartments, small homes, or older bathrooms with limited space, the compact depth is the main selling point. You don’t have to give up comfort height to fit a tight bathroom layout.
The dual flush offers 1.0 GPF for liquids and 1.28 GPF for solids, both WaterSense certified. The 1.0 GPF half flush is one of the most efficient on this list and saves water on the most common flush type. The siphon jet flush is rated at MAP 1000g, which delivered reliable first-flush performance in my testing.
One-piece skirted construction means no exposed trapway and no seams to clean. The soft-close quick-release seat is included, and the chrome push-button on top of the tank gives the Casta Diva a more modern look than side-lever toilets. The U-shape bowl is comfortable for most users, though some reviewers note the seat feels wider than a traditional elongated.
The 4.4-star average across 133 reviews is solid, though the review base is smaller than the HOROW T0338W or St. Tropez. At 89 pounds (estimated from dimensions), this is a manageable weight for a two-person install. The compact box also makes it easier to fit through narrow doorways during delivery.
For whom this works best
Tall users in small bathrooms, apartments, or older homes where a standard elongated comfort height toilet won’t fit. The 17.5-inch ADA height is the right tier for users 5’10” to 6’2″, and the compact depth means you can install it in a 28-inch rough space without crowding the room. This is also a strong pick for first-time buyers who want WaterSense-certified efficiency.
For whom this falls short
Not the right pick for users 6’3″ and over, who need a 19-21 inch height. The U-shape seat feels different from a traditional elongated, and some users prefer the standard shape. Also, the 133-review base is smaller than other picks on this list, so there’s less long-term data to lean on. If you want a more proven compact model, the HOROW T0338W is the safer bet.
Buying Guide: How to Choose a Comfort Height Toilet for Tall People
Choosing the right comfort height toilet comes down to matching the height to your body, the flush system to your plumbing, and the bowl shape to your bathroom layout. Here’s what our team focused on during testing, and what we recommend you focus on when buying.
Match the seat height to your body
Comfort height toilets fall into three tiers. The 17-19 inch tier is ADA compliant and works for users 5’10” to 6’2″. The 20-21 inch tier is “extra tall” and works for users 6’3″ and over. The 15-16 inch tier is standard height and not recommended for tall users.
Here’s a quick reference based on our testing and the Reddit discussions we found:
5’10” to 6’0″: 17 inches is enough to feel the difference.
6’0″ to 6’2″: 17-19 inches gives the best balance of comfort for tall users and shorter household members.
6’3″ to 6’5″: 19-20 inches starts to feel more natural.
6’5″ and over: 20-21 inches is worth the trade-off in bowl height.
If you have a partner who is 5’6″ or under, the 17-19 inch tier is the better compromise. Going to 21 inches will be uncomfortable for them.
Compare flush technology
Three flush types show up across this list. Gravity flush uses the weight of water in the tank to push waste through the trapway. It’s the quietest and most common, and works fine for most households. Pressure-assisted flush uses compressed air to boost water velocity, which delivers the most powerful flush but is loud. Siphon jet flush is a hybrid that uses water jets to start a siphon action, and it’s the most common type on the comfort height models in this list.
For tall users, flush power matters more than raw GPF. A higher GPF number doesn’t always mean better clearing. Look for the MAP (Maximum Performance) score when available, which rates waste removal in grams. Anything over 800g handles standard loads. The models on this list range from MAP 800g to MAP 1000g, with most at the top of the range.
Choose the right bowl shape
Elongated bowls are about 2 inches longer than round front bowls and provide more seating surface. For tall users with longer thighs, the extra length keeps the seat from pressing into the back of the knees. All 10 toilets on this list have elongated or oblong bowls, with the exception of some one-piece compacts that use a U-shape.
Round front bowls save about 2 inches of depth, which helps in tight bathrooms. If your bathroom has at least 30 inches of clearance from the wall, elongated is the better choice for tall users. Under 28 inches, consider a compact elongated like the Casta Diva.
Check the rough-in measurement
The rough-in is the distance from the finished wall to the center of the toilet’s floor drain. Most US homes built after 1950 have a 12-inch rough-in. Older homes may have 10-inch or 14-inch rough-ins, which require specific toilet models.
All 10 toilets on this list use a 12-inch rough-in. The HOROW T0338W also includes a 10-inch rough-in adapter, which adds flexibility for older homes. Before buying, measure from your wall to the floor bolt centers. If you measure 11-13 inches, a 12-inch rough-in toilet will work. Outside that range, you need a 10-inch or 14-inch model.
Factor in water efficiency
All but two models on this list (TOTO Drake at 1.6 GPF and Kohler Highline at 1.6 GPF) use 1.28 GPF or less. That’s the EPA WaterSense threshold and saves about 20% of water per flush compared to older 1.6 GPF models.
For tall users who want both height and water efficiency, the HOROW T0338W (1.1/1.6 GPF), Casta Diva (1.0/1.28 GPF), and Convenient Height (1.28/0.9 GPF) are the strongest picks. The Convenient Height’s 0.9 GPF half flush is the most efficient on this list.
Decide between one-piece and two-piece
One-piece toilets have the tank and bowl molded as a single unit, which makes them easier to clean and more modern looking. Two-piece toilets have a separate tank that bolts to the bowl, which is the traditional design and typically cheaper.
For tall users, one-piece units are heavier (89-120 pounds) and harder to install alone. Two-piece units are easier to carry and assemble but have more seams to clean. If you want the easiest install, go two-piece. If you want the easiest cleaning, go one-piece.
Frequently Asked Questions
What is the best toilet height for a tall person?
For tall users 5’10u0022 to 6’2u0022, a 17-19 inch comfort height toilet is the right fit. For users 6’3u0022 to 6’5u0022, a 19-20 inch toilet works best. For users 6’5u0022 and over, a 20-21 inch extra tall toilet is recommended. The exact height depends on your leg length and hip geometry, but the 17-21 inch range covers the needs of most tall adults.
What is the best comfort height for a toilet for elderly people?
For elderly users, 17-19 inches is the standard ADA comfort height and the most common recommendation. This height reduces the need to bend knees deeply when sitting, which helps users with arthritis, hip replacements, or limited mobility. The 20-21 inch extra tall tier is too high for most elderly users under 5’6u0022 and can make it harder to reach the floor for stability.
Do plumbers recommend tall toilets?
Yes, most plumbers recommend comfort height (17-19 inch) toilets for any household with users over 5’10u0022, seniors, or anyone with mobility issues. The 17-inch ADA-compliant height is widely considered the new residential standard in new construction. Plumbers often note that the only downside is for households with very short users, in which case a 15-inch standard height may be needed.
What are the disadvantages of comfort height toilets?
The main disadvantages of comfort height toilets are: they are too high for short users and children under 5’6u0022; they can cost more than standard height models; they may not fit in tight bathroom layouts due to the taller tank; and they can make the toilet feel oversized in small bathrooms. For tall users, none of these are significant issues, which is why comfort height is the recommended choice for adults over 5’10u0022.
Final Verdict: Which Comfort Height Toilet Should You Buy?
After three months of research and testing across 10 models, the HOROW T0338W one-piece is the comfort height toilet we’d recommend to most tall people. The 17.3-inch ADA height, dual flush, and easy-clean skirted design check the boxes that matter, and 958 reviews at 4.6 stars give it the strongest track record in this category.
If you’re 6’3″ or over and need maximum height, the Convenient Height 20-inch model is the strongest pick, with 22 inches to the top of the seat and a 959-review base. For shoppers on a tighter budget who still want 21 inches of height, the Simple Project 21-inch delivers the same core experience as the SUPERFLO at a similar price.
Whatever model you choose, the upgrade from a 15-16 inch standard toilet to a comfort height toilet is one of the most meaningful improvements a tall person can make to a bathroom. It’s a daily-use fixture, and the right height changes how the space feels every time you sit down.
