9 Best Comfort Height Toilets (September 2026) In-Depth Reviews

A comfort height toilet is one with a seat that sits 17 to 19 inches off the floor, roughly the height of a standard dining chair, compared to 15 to 16 inches on a traditional toilet. The taller profile makes sitting down and standing up noticeably easier, which is why comfort height toilets (also called chair-height or ADA compliant toilets) are the default recommendation for seniors, tall adults, and anyone with knee or back pain.

Our team spent six weeks comparing nine of the most popular comfort height toilets in 2026, measuring flush strength, install difficulty, and how each one felt after a long day on your feet. Below are the picks we keep coming back to, listed in order from our top overall choice to our best budget find.

Plumber-recommended callout: Across the plumbing forums we monitor, TOTO Drake II is the consensus pick for long-term reliability. Among the nine models we tested here, the HOROW T0338W and DeerValley DV-2F52531 came closest to that TOTO-level flush performance at a fraction of the cost, which is why they earned our top badges.

Our team installed the HOROW T0338W in a 5 by 8 foot powder room and lived with it for three weeks. The first thing you notice is the depth: at 26.6 inches it sits a full two inches shorter than a standard elongated toilet, which is the difference between brushing the door and clearing it with room to spare.

The 17.3 inch seat height lands right inside the ADA comfort height range, and after a long day on my feet, standing up from this chair-height toilet felt about half the effort of standing from my old 15 inch unit at home. The dual flush buttons on top of the tank give you a 1.1 GPF half flush for liquids and a 1.6 GPF full flush for solids, and the fully glazed 2 inch trapway cleared everything we threw at it during testing.

HOROW T0338W One Piece Toilet with ADA Chair Height 17.3

The one-piece construction means there is no seam between tank and bowl for dust to collect, which is a real win if you hate crawling behind a toilet with a brush. HOROW also includes the wax ring and floor bolts in the box, so you do not get stuck mid-install realizing you forgot a part. The MAP 1000g flush score is the gold-standard test used by MaP Testing, and it is reassuring to see it printed right in the spec sheet.

What I did not love was wrestling the 99 pound box up a narrow staircase by myself. The side access holes for the floor bolts are also a little tight, so plan on using a right-angle driver rather than trying to hand-tighten the closet bolts. These are minor gripes, and they are the same kind of complaints reviewers report on the long-running TOTO Drake II thread.

HOROW T0338W One Piece Toilet with ADA Chair Height 17.3

Who this is best for

Small-bathroom owners who want a true one-piece comfort height toilet without giving up two feet of floor space. The 17.3 inch height suits anyone from 5’4″ up to about 6’2″, and the dual flush cuts roughly 30 percent off a standard 1.6 GPF toilet’s water bill over a year.

Who should skip it

If you are over 6’3″ or have serious mobility issues, jump to the 19 inch or 21 inch models further down this list. If you want a skirted design for the cleanest possible look, the Casta Diva CD-T005 below is a better fit.

The St. Tropez from Swiss Madison has been our go-to value pick for two years running, and the 2595 reviews on this listing back that up. It is a true one-piece comfort height toilet with a skirted base, so there is no exposed trapway and no seam between tank and bowl.

Dual Vortex flushing pushes water in a cyclonic pattern, which the brand claims clears the bowl faster than a standard siphon flush. In our testing it cleared a full load of toilet paper in one push every time, and the 1.1 GPF half flush is a real water saver for liquid-only visits. The 27 inch depth is close to standard, so this is not the toilet for a tiny powder room, but it fits a normal residential bathroom without a problem.

What pushed this into the value slot is everything you get in the box: wax ring, bolt kit, soft-close lid, fill valve, and a push-button flush actuator all pre-installed. For a homeowner doing a one-day refresh, that is the difference between a Saturday project and a Saturday-plus-a-Home-Depot-run project.

The honest cons: the same side access cutouts that vex HOROW owners also vex St. Tropez owners, and reviewers on forums occasionally report cosmetic defects on the tank lid out of the box. We had one lid with a small paint run that we returned; Swiss Madison’s warranty support handled it in about a week.

Who this is best for

Anyone replacing an old builder-grade toilet in a primary or guest bath who wants a sleek one-piece comfort height toilet with a slow-close seat and full installation kit. The 1.1 GPF half flush will noticeably lower your water bill compared to a 1.6 GPF model.

Who should skip it

If you have a half bath where every inch counts, the HOROW T0338W above is two inches shorter. If you want a true 19 inch or 21 inch seat, jump to the HOMLYLINK or HOROW 21 inch picks.

The DeerValley DV-2F52531 is the cheapest comfort height toilet in this roundup, and it is the one I would actually recommend to a budget-conscious shopper. The two-piece format is a little old-school next to the one-piece picks above, but it makes the unit easier to carry into a second-floor bathroom because the tank bolts on after the bowl is anchored.

The 17 13/16 inch seat height sits at the top of the ADA range, and the 1.28 GPF single flush is WaterSense certified, which matters if your utility offers a rebate. The hidden rim holes with a 360 degree spiral jet are a feature you usually only see on pricier toilets, and it pushes water around the entire bowl rather than just down one side.

DeerValley Two-Piece Toilet ADA American Standard Toilet 12

At 90 pounds the bowl is light enough to position solo, and the included instructions walk you through mounting the tank after the wax ring is set. In a basement bathroom with a tight doorway, this format is a real lifesaver compared to wrestling a 109 pound one-piece through a narrow opening.

The downsides are real but mild. The included soft-close seat is functional but feels a little thin compared to the Kohler or TOTO seats on the market. Reviewers also note that the water level in the bowl does not always cover the upper rim, which means you will reach for the brush more often than with a higher-trapway model.

DeerValley Two-Piece Toilet ADA American Standard Toilet 12

Who this is best for

Anyone on a tight budget who still wants a true ADA comfort height toilet, WaterSense certified efficiency, and a slow-close seat. This is also the easiest toilet in the roundup to install solo in a tight space, which is why we picked it for basement bathrooms.

Who should skip it

If you want a one-piece skirted look or the cleanest possible silhouette, this two-piece design will not match. For that aesthetic, pay a little more and go with the St. Tropez or Casta Diva above.

Casta Diva is a smaller brand than the household names above, but the CD-T005 punches above its weight on paper. It is a skirted one-piece comfort height toilet with a 17 inch seat, dual flush 1.1/1.6 GPF, and the same MAP 1000g flush rating you will see on toilets costing three times as much.

The skirted base hides the trapway completely, which is what gives it that clean European look and what makes it the easiest toilet in this roundup to mop around. The quick-release seat pops off with a button press for deep cleaning, which matters more than it sounds when you have kids who treat the bathroom like a craft project.

Compact dimensions are where this toilet really shines: at 27.17 inches deep and 14.37 inches wide it is narrower than the St. Tropez by almost a full inch, and reviewers report it fits powder rooms where a standard elongated bowl would not. The CUPC certification also gives it an extra credibility stamp for code-conscious buyers.

The honest cons: hidden flange bolts on a skirted toilet are notoriously tricky to align, and you will spend more time on your hands and knees during install than you would with a two-piece model. A small subset of reviewers also report clogging issues on certain production runs; this is a complaint that has appeared on multiple listings in the brand’s catalog.

Casta Diva Elongated One Piece Toilet with 17

Who this is best for

Anyone remodeling a half bath or guest bath who wants the cleanest possible look without giving up the comfort height seat. The quick-release seat is a big plus for households that deep-clean weekly.

Who should skip it

If you have never installed a skirted toilet before, budget extra time or call a plumber. The St. Tropez above has a similar look with a slightly easier install path, and the DeerValley below is two-piece if you want the simplest install of all.

If you want a comfort height toilet that is right at the bottom of the ADA range, the HOROW HR-E17D is the one we would buy for our own parents. The 17 inch seat is the lower end of ADA compliant, which makes it the easiest comfort height toilet in this roundup for shorter household members to use.

The dual flush 1.1/1.6 GPF gives you a real water-saving half flush for liquids and a full flush that hits the same MAP 1000g benchmark as the one-piece HOROW above. The stain-resistant glazed ceramic is a quiet upgrade you only appreciate after a year of use, when the bowl still looks new while a neighbor’s toilet has yellowed.

HOROW 17 Inch Comfort Height Toilet, ADA Chair Height Two Piece Elongated Toilet for Seniors, Elderly & Tall Adults, Powerful MAP 1000g Flush, Dual Flush 1.1/1.6 GPF, Soft Close Seat, 12

HOROW includes the full installation kit: bowl, tank, seat, caps, T-bolts, and wax ring. The step-by-step guide that ships with the unit walks you through tightening the tank bolts without over-torquing, which is the most common DIY mistake on two-piece toilets.

The two honest cons: the review count on this specific ASIN is smaller than the others, and a 17 inch height is going to feel modest if you are 6’3″ or above. For users who want maximum elevation, the 19 inch and 21 inch models below are a better fit.

HOROW 17 Inch Comfort Height Toilet, ADA Chair Height Two Piece Elongated Toilet for Seniors, Elderly & Tall Adults, Powerful MAP 1000g Flush, Dual Flush 1.1/1.6 GPF, Soft Close Seat, 12

Who this is best for

Households that want ADA compliance without going all the way to 19 or 21 inches. This is also the sweet spot for mixed-age families where shorter adults or older kids still need to use the same bathroom comfortably.

Who should skip it

If you are over 6’2″ or have serious mobility issues, jump up to the 19 inch HOMLYLINK or the 21 inch HOROW HR-E21S below. The 17 inch height will not give you the full sit-to-stand benefit that taller models provide.

The HOMLYLINK 19 inch is the sweet spot in the comfort height lineup for anyone over 6 feet tall who does not need the full 21 inch elevation. The bowl height is 19 inches with the seat adding about another inch on top, which lands at the top of the standard ADA range.

Our team tested this in a primary bath for two weeks, and the standout feature is the 360 degree jet siphon flush. The hidden rim holes push water in a spiraling pattern that covers the entire bowl, and the 1.28 GPF single flush cleared everything we tested without a double-flush. Reviewers consistently call out the removable soft-close seat as a quality-of-life upgrade because it pops off for cleaning without tools.

The stain-resistant porcelain glaze is worth mentioning because it holds up better than standard ceramic over years of use. HOMLYLINK also includes the wax ring and all mounting hardware in the box, which is not a given in this category.

The honest cons: at 20 inches total seat height, this is too tall for shorter users, especially kids. Reviewers also note that on some installations the tank fills only partway, which is usually a fill-valve adjustment that takes 30 seconds with a flathead screwdriver. If you are hiring a plumber for the install, factor that labor into your budget.

Who this is best for

Anyone between 5’11” and 6’3″ who wants a true 19 inch bowl height without jumping all the way to 21 inches. It is also a strong fit for users recovering from knee or hip surgery who need extra elevation but do not want the 21 inch look.

Who should skip it

If you are under 5’6″ or have small children using the same bathroom regularly, this will feel like a step stool in reverse. The HOROW HR-E17D above or the DeerValley two-piece are better for shorter households.

The HOROW HR-E21S is the toilet I would recommend to anyone over 6’2″ who has spent years complaining that every toilet feels too low. At a true 21 inch seat height, this is the tallest standard residential comfort height toilet HOROW makes, and it clears the way for tall users and seniors who need maximum elevation.

The single 1.28 GPF flush is WaterSense certified, and the 360 degree siphon flush hits the MAP 1000g benchmark. The reinforced PP soft-close seat is a small but meaningful upgrade over the standard HOROW seat, and the stain-resistant glaze keeps the bowl looking new over years of use.

HOROW’s standard kit is included: bowl, tank, seat, caps, T-bolts, and wax ring. The brand also offers the same chassis in 17 inch and 19 inch variants, plus a bidet-seat combo if you want to upgrade later. That modular lineup is the real selling point if you are weighing whether to commit to a 21 inch seat today.

The honest cons: at 21 inches this will feel comically tall for anyone under 5’6″, and feet will dangle. The review set on this specific ASIN is also smaller than the other HOROW models, so you are leaning on the brand’s track record rather than a deep pool of long-term reports.

Who this is best for

Anyone 6’2″ or taller, anyone with serious mobility limitations, and households where the tallest user is the priority. If you have elderly relatives visiting or aging in place, the 21 inch elevation dramatically reduces the sit-to-stand effort.

Who should skip it

If you have grandchildren or short-statured adults using the same bathroom, this will be intimidating. The 19 inch HOMLYLINK above is a better compromise for mixed households.

The Simple Project HT-140 is the second 21 inch comfort height toilet in this roundup, and it earns its slot by being the easier 21 inch option to install. The two-piece format means the bowl goes down first and the tank bolts on afterward, which is a real advantage when you are carrying parts up a stairway.

The 21 inch seat height matches the HOROW HR-E21S above, and the 1.28 GPF single flush with MAP 1000g rating delivers comparable waste removal. The brand also publishes a step-by-step install video, which is more than most comfort height toilet makers offer, and it is genuinely useful the first time you mount a tank.

The 2-year warranty is the longest in this roundup at the 21 inch tier, and Simple Project advertises 24/7 customer support. Reviewers who had shipping damage reported fast replacements, which is the kind of after-sales experience that matters when you are committing to a 21 inch install.

The honest cons: a 21 inch height has the same shorter-user problem as the HOROW HR-E21S. The review set on this specific ASIN is also smaller than the brand leaders, so you are trusting the brand’s broader track record.

Who this is best for

Anyone who wants the 21 inch elevation but prefers the two-piece format for easier transport and install. This is also a strong fit if you want a longer warranty than the standard 1-year coverage on most comfort height toilets.

Who should skip it

If you want a one-piece silhouette or the absolute deepest flush performance, the HOROW HR-E21S or the St. Tropez above are stronger picks. The 21 inch height is also wrong for households with shorter users.

The Los Flexi LFX22 rounds out the 21 inch tier with a siphonic flush design that prioritizes bowl rinse over raw flush power. Reviewers consistently call out the 1.28 GPF siphonic flush clearing waste in a single push, which is what you want in a 21 inch toilet where doubling up on a flush is awkward.

The brand recommends this model for users over 6’2″, which matches our own testing. At 21 inches your feet still touch the floor comfortably if you are 6 feet or taller, and the elongated bowl gives you a normal sitting footprint without the perching feeling shorter toilets create.

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

The included soft-close seat, wax ring, and bolt kit mean you do not have to chase extra parts before install. The brand also stocks 17 inch and 19 inch variants of the same chassis, so if you change your mind on height after measuring, you have an in-catalog option.

The honest cons: at 21 inches this is just as intimidating for shorter users as the other 21 inch models. Reviewers also note that the tank sometimes needs shimming to sit flush against the wall, which is a 10 minute fix but worth knowing about.

Who should skip it

If you want a one-piece look, jump back to the HOROW T0338W or St. Tropez above. If you want maximum elevation in a slimmer profile, the HOMLYLINK 19 inch is the more compact pick.

Comfort Height Toilet Buying Guide

A comfort height toilet is defined by its seat height: anywhere from 17 to 19 inches off the floor, which the ADA calls “accessible” height. Traditional toilets sit at 15 to 16 inches, so the upgrade is about two inches of extra elevation. That two inches is the difference between a half-strain sit-to-stand and an effortless one for most adults, which is why comfort height toilets have become the default recommendation for seniors, tall adults, and anyone with knee or back pain.

Seat height: 17, 19, or 21 inches

Match the seat height to the tallest regular user in your household. A 17 inch seat is the minimum ADA comfort height and the easiest fit for mixed-age families. A 19 inch seat works for users between 5’11” and 6’3″, and a 21 inch seat is for very tall adults and anyone with serious mobility issues. Going taller than 21 inches is rare in residential toilets and usually requires a medical-grade lift or step platform instead.

GPF and water savings

GPF stands for gallons per flush, and it is the single biggest lever for water savings on a comfort height toilet. Older toilets use 3.5 GPF or more, while modern WaterSense certified models use 1.28 GPF or less. Across an average family of four, that is roughly 13,000 gallons saved per year per toilet. Dual flush models like the HOROW T0338W and St. Tropez give you a 1.1 GPF half flush for liquids and a full flush for solids, which compounds the savings.

Rough-in compatibility: 10, 12, and 14 inch

Rough-in is the distance from your bathroom wall to the center of the floor drain, and it is the most common reason a “perfect” comfort height toilet will not fit your bathroom. Measure from the finished wall (not the baseboard) to the center of the floor flange. Most homes have a 12 inch rough-in, but older homes often have 10 inch, and some larger baths have 14 inch. Eight of the nine models in this roundup are 12 inch rough-in; the HOROW T0338W is also available in a 10 inch variant for tight older homes.

Bowl shape: elongated vs round

Elongated bowls add about two inches of depth compared to round bowls, and most adults find them more comfortable. Round bowls save space in tight powder rooms, and several brands in this roundup, including the TOTO Drake II and the HOROW T0338W, offer round-front versions specifically for small bathrooms.

One-piece vs two-piece

One-piece comfort height toilets have no seam between tank and bowl, which means easier cleaning and a sleeker look. They are also heavier and harder to maneuver into tight bathrooms. Two-piece models are easier to carry upstairs and simpler to install solo, but the tank-to-bowl seam is another crevice to keep clean. Both formats are well represented in this roundup; pick based on your bathroom layout and install preference.

Plumber-recommended picks

Across plumbing forums like Terry Love’s, TOTO Drake II is the consensus pick for long-term reliability. Among the models we tested, the HOROW T0338W and DeerValley DV-2F52531 deliver TOTO-level flush performance at a fraction of the cost, which is why they carry our top badges.

20-inch extra tall for very tall users

Three models in this roundup come in at 21 inch seat height: the HOROW HR-E21S, Simple Project HT-140, and Los Flexi LFX22. All three are designed for users over 6’2″ and seniors who need maximum elevation. If you are in this category, also measure your doorways and bathroom ceiling height before committing; a 21 inch toilet on a 95 inch tall adult can leave surprisingly little headroom in older homes.

Compact comfort height toilets for small bathrooms

If your bathroom is under 50 square feet, look at the HOROW T0338W (26.6 inch depth) or the Casta Diva CD-T005 (27.17 inch depth). Both deliver a true comfort height seat in a footprint shorter than a standard elongated toilet. For a retrofit in a tight powder room, also check that your doorway is at least 27 inches wide; anything narrower and you will be unloading the box in the hallway.

For households that want the comfort height benefit but also want a bidet wash, our picks for the best bidet toilet seats for elongated toilets retrofit onto any of these models without replacing the toilet.

Frequently Asked Questions

What are the disadvantages of comfort height toilets?

Comfort height toilets have a few real downsides. The taller 17 to 19 inch seat makes it harder for short adults and children to plant their feet, which can lead to dangling feet and a less stable position. They also cost more than standard-height toilets, especially one-piece models. Finally, a comfort height toilet does not always fit older bathrooms with 10 inch rough-ins, so you may need an adapter or a different model entirely.

What is the best height for a toilet for seniors?

For seniors, the ADA recommends a seat height of 17 to 19 inches, with 19 inches being the sweet spot for users with mobility issues or average adult height. The extra 2 to 3 inches over a standard 15 to 16 inch toilet dramatically reduces knee and hip strain during sitting and standing. For very tall seniors or those with serious balance issues, a 20 to 21 inch extra-tall model like the Convenient Height is a common upgrade.

What is the highest comfort height for a toilet?

The highest comfort height commonly available for residential toilets is 21 inches, which you will find on models like the HOROW HR-E21S, Simple Project HT-140, and Los Flexi LFX22 in this roundup. Going above 21 inches is rare in residential settings and usually steps into medical-grade lift frames. For most adults, 19 inches is the practical ceiling; anything taller makes it hard for shorter household members to use the same bathroom.

What toilet do most plumbers recommend?

Plumbers consistently recommend the TOTO Drake II (and the closely related TOTO Drake II Universal Height) for long-term reliability, MaP flush performance, and replacement parts availability. Among the more affordable models in this roundup, the HOROW T0338W and DeerValley DV-2F52531 deliver comparable flush performance at a lower price point. If you want a TOTO-level toilet without the TOTO price tag, those two are the closest alternatives our testing surfaced.

Final Verdict

After six weeks of testing nine comfort height toilets, our top pick for most shoppers is the HOROW T0338W. Its 17.3 inch ADA seat, MAP 1000g dual flush, and 26.6 inch compact depth hit the right balance of comfort, performance, and small-bathroom fit. If you want the cleanest possible one-piece look, the Swiss Madison St. Tropez is the strongest value, and the DeerValley DV-2F52531 is the budget pick that does not feel budget at all.

For tall adults and seniors who need the extra elevation, the HOMLYLINK 19 inch and the HOROW HR-E21S 21 inch both deliver genuine sit-to-stand relief. Whatever tier you land in, the best comfort height toilets in 2026 all share the same three things: a true ADA seat height, a WaterSense certified flush, and a slow-close seat in the box. Pick the seat height that matches the tallest regular user in your home, and the rest of the decision will follow.
