5 Best Comfort Height Toilets 2020: 17+ Inch Tall Toilets

We sit on our toilet for about half an hour every day. Of course, we want to be sitting comfortably.

We have already switched from reading newspapers on the toilet to messing around with our mobile phones. The toilet design is catching up to what we want when sitting on the toilet: comfortability.

That’s why we see more and more comfort height ADA toilets on the market that are especially useful for elderly people and people with bad knees who can’t easily sit down and stand up from a toilet.

What is the difference between a standard height and comfort height toilet?

The difference, obviously, is the height measured from the floor to the seat. The standard height of the toilet is 15” to 17” and some people find that quite uncomfortable. That’s why companies like KOHLER have developed 17” to 19” high comfort height toilets that have 3 distinct advantages:

  1. Easier to sit down (especially useful if you have bad knees).
  2. Easier to stand up.
  3. Pretty much everybody finds them more comfortable (more leg space).

#1 KOHLER K-6669-0 Memoirs Stately Review (The Ultimate Comfort Height Toilet)

If you’re picking toilets, you must know KOHLER. They are one of the best and most recognized brands in the toilet industry and they were actually the ones who pretty much invented the expression ‘comfort height toilet’.

They’ve developed more comfort height toilets than any other brand and the best comfort height toilet they’ve ever made is the KOHLER K-6669-0 Memoirs Stately.

This is the Memoirs Stately, the KOHLER’s crowning jewel of comfort height toilets:

KOHLER K-6669-0 Memoirs Stately as the best kohler comfort height toilet in a bathroom setting
KOHLER K-6669-0 Memoirs Stately is the pinnacle of comfort height toilet design and editorial #1 choice.

The distance from the floor to the top of the seat is 18”. That makes the Memoirs Stately toilet a perfect height comfort toilet. But the easy sitting and standing from a toilet aren’t the only two things that make the K-6669-0 model the best; it’s all the additional advantages that KOHLER decided to enrich this toilet with.

The 2 big advantages are the elongated toilet seat (for more comfortable sitting) and the water-saving Aqua Piston flush technology. That’s the flushing technology that enabled the water to enter the bowl from all sides (360 degrees) when flushing. You’ll only ever need 1.28 gallons per flush; making the Memoirs Stately Toilet eco-friendly and water-bill-friendly and landing the #2 place on the list of the best low flow toilets.

Don’t miss the little details as well. The trip level you see there is polished chrome, giving a design boost. The flush valve with it’s 3:2 diameter ratio help gravity do its job when flushing.

They’ve even made improvements to help you with easier cleaning. The trap way is easy-clean and the canister design leaves a lot less exposed material than a normal flapper. It also reduces the leakage problems that majority of other toilets might have.


  • Elongated toilet seat (comfy sitting).
  • Eco-friendly and water-friendly 1.28 GPF Aqua Piston technology.
  • Extremely easy to clean.
  • Canister design = Fewer leakage problems.
  • Best KOHLER comfort height toilet (18 inches).


  • It is a two-piece toilet.
  • Doesn’t come with a toilet seat included.

#2 Convenient Height Extra Tall Toilet Review (Incredible 21 Inches)

The Convenient Height company took the comfort height toilet to completely new heights.

Here’s the approximate comparison of a distance from the floor to the top of the toilet seat for different toilets:

  • Standard height toilet: 15”
  • Comfort height toilet: 18”
  • Extra tall by Convenient Height toilet: 21”

The Convenient Height toilet is incredibly tall. It’s so tall that we have to ask ourselves ‘what is considered comfort height toilet?’ Comfort height is between 17” and 19” and this toilet is so tall that it just penetrates the upper barrier by a full 1”.

That makes sitting down and standing up incredibly easy and especially useful if you have bad knees. However, if you have short legs, the height of this toilet might be too much. For everybody with normal or above-normal length legs, this is the world’s tallest toilet:

Convenient Height toilet is the tallest comfort height toilet at 21 inches. The easiest sitting down and standing up for non-short people.
Convenient Height toilet is a tall toilet at 21 inches. The easiest sitting down and standing up for non-short people.

In fact, the Convenient Height toilet is taller than most of the comfort height toilets and even taller than the ADA toilet height requirements. It is further approved by the Board of Registration of Plumbers GF and CEC.

The truly incredible thing is that a toilet of such height is so cost-saving. It has a dual 1.28/0.9 GPF flush; the 0.9 gallons is as low as one can go as far as water use per flush. This is all thanks to the dual flush economy valve.

To elivieate even more problems with the day-to-day running of the toilet, the Convenient Height toilet has a slow-close seat. That means the toilet seat moves slowly towards the bowl (doesn’t smack on the bowl).


  • Very tall with 20” to the rim and 21” to the top of the toilet seat.
  • Cost-saving dual flush valve – 1.28/0.9 GPF.
  • Might be tax-deductible.
  • Approved by Board of Registration of Plumbers GF
  • Helps prevent falls.


  • Might be too tall for short people.
  • Installation instructions are not exactly to the point.
  • Thin toilet seat (1”).

#3 TOTO Eco Ultramax Shorter Comfort Height Toilet Review (Best by TOTO)

With the MS854114EL#01 model, TOTO, the most popular Japanese toilet maker, satisfies the customers who are used to standard height toilet and want to switch to the comfort height toilet. But they’re not ready to make that big leap from 16” toilet to a 18” toilet just yet.

The TOTO Eco Ultramax toilet is right there in between. Is has a 16.5” distance from the floor to the rim and on top of that is a comfortable 1.2-inch toilet seat bringing the total height (from floor to the top of the seat) to about 17.7”.

Most comfort height toilets are 18” tall and some people do find them just a bit too tall. That’s exactly the kind of people who’re transitioning from standard height to comfort height toilet that the TOTO Eco Ultramax is perfect for.

Here are the measurements of the best TOTO comfort height toilet:

shorter comfort height toilet that is 0.3 inch shorter than standard comfort height toilet
The Eco Ultramax is the best TOTO comfort height toilet. It’s a bit under 18”, making it perfect for people who’re transitioning from standard height to comfort height toilet and don’t want that giant leap in height.

The Eco Ultramax has all the benefits the Japanese design TOTO is known for has. They’ve spared no expense as far as the style goes. You can see that Eco Ultramax comfort height toilet is a one-piece toilet with the elongated bowl and seat for comfiness.

The Japanese are also meticulous when it comes to the flush volume. With the introduction of the fast E-Max flushing system, you’ll only need 1.28 gallons per flush.

It’s smaller cousin – TOTO Ultramax II Hex – even made the Top 5 Best Toilets list because of the advantages it shares with the Eco Ultramax.

The flushing system is faster than a convenient flushing system thanks to the 3-inch flush valve. If you remember the formula for the surface area, you can quickly deduct that the 3-inch valve is actually 125% bigger than a standard 2-inch valve as far as the surface area is concerned.


  • 17.7” comfort height – perfect for people transitioning from standard height to comfort height toilet.
  • E-Max flushing system with 1.28 GPF.
  • Has 125% bigger valves (faster flushing).
  • Elongated and one-piece toilet.
  • Beautiful Japanese design TOTO is known for.


  • Difficult to assemble.
  • Not a standard comfort height toilet (0.3” lower).

If you want to have a comfort height toilet with a bit of futuristic design, the WOODBRIDGE T-0001 model might be just the toilet you’re looking for.

Furthermore, when you hear dual flush with WaterSense in the same sentance, you know you’re looking at a water-saving eco-friendly toilet. The small flush only uses a single gallon of water.

#5 American Standard 2886518.020 H2Option (Why Are They Calling It Right Height Toilet?)

American Standard is the most successful and popular US toilet brand. They are known for reliable and affordable toilets, and of course, they too have ventured into the world of the comfort height toilets.

However, American Standard calls their +17” comfort height toilets by another name – they are ‘right height toilets’. That’s because the expression ‘comfort height’ was put forward by their competitor KOHLER and, obviously, the American Standard had to brand their own design of the tall toilets; promptly naming them ‘right height toilets’.
