  • canister flush valve is less prone to leaks;

What Makes a Chair Height Toilet Better than Other Options?

The answer is obvious:

Its height.

See, the comparison with the chair isn’t accidental. The majority of doctors and chiropractors agree that the most comfortable chair seat height is 16’’ to 21’’. It allows you to sit with your feet staying on the floor and thighs in a horizontal position (1). 

Chair height toilets are exactly the same. Moreover, they have some significant advantages:

  • They suit people of any body composition. Taller people have longer legs, so the standard height of the bowl may feel short and uncomfortable for them, as it puts knees higher than the pelvis. A 16-inch seat or higher (up to 20-21 inches) will make a better pick if you need a toilet for a tall person.
  • They require less physical effort to use. When you sit on a chair height toilet, your thighs are horizontal, so you don’t need to fully engage your leg muscles to stand up. This may be convenient for those who have weak knees or certain mobility issues that limit their leg strength. 
  • They may meet ADA guidelines. The Americans with Disabilities Act (ADA) establishes the accessibility standards, so elderly, handicapped, or disabled people can have a good quality of life. ADA compliant toilets should have a 17-inch seat height (min) or 19-inch height (max). As you can see, the term ‘comfort height’ is a bit broader than ‘ADA compliant’ and if you need a really tall toilet for the elderly, take a look at some of the chair height models.

And the 16.5’’ bowl height seems pretty sufficient for us to include this unit in the selection. But there are a couple more features.

This Kohler unit utilizes a dual flush technology that helps you regulate water consumption. If you turn the trip lever up, it triggers a partial 0.9-gallon flush. If you press it all the way down, a 1.28 AquaPiston flush will scrub the bowl clean and discard any waste.

Despite using a canister-type valve, the Santa Rosa doesn’t make any loud noises during flushing. Also, it comes with a soft-close Brevia seat made of hard plastic that will make your experience even more enjoyable. 

The cherry on top is the overall one-piece design of the unit which is easier to clean. Plus, it’s available in seven different colors from White to Black and can match absolutely any interior.

The most prominent feature of the Champion-4 unit is the combination of the 4-inch flapper valve and 4-inch wide trapway, which results in the effortless elimination of the large loads of waste. The water enters the bowl from all sides simultaneously and scrubs the bowl clean.

Plus, the toilet features the EverClean glaze that coats even the insides of the trapway, so the waste has no chance to adhere to its surface and its removal requires only 1.6 gallons per flush.

The toilet comes with a soft-close seat that adds half of an inch to the height and makes it compliant with the ADA’s regulation. So if you share a home with an older relative, this toilet makes a perfect accessible pick.

Convenient Height 20-inch Extra Tall Toilet

If you’re taller than 6 feet or have very bad knees, even the best chair height toilet might fail for you and you might need something taller. This is when the Convenient Height unit comes in handy. The bowl of this toilet measures 20 inches from the floor and the seat adds an inch more for extra comfort and bathroom safety. 

Aside from that, the Convenient Height unit features a water-efficient dual-flush that uses 0.8 gallons for liquid and 1.28 gallons for solid waste. Thus, you can save up more than 16,500 gallons of water per year. Also, the toilet uses its elongated trapway to create a powerful siphon action that prevents clogging and allows you to flush larger loads.

The Convenient Height unit includes a soft-close seat with a lid that fits the elongated bowl just right. This seat, along with the gravity-assisted flush, ensures a quiet operation, which is great if you live with someone who’s sensitive to sounds.


  • A great choice for tall people, people with bad knees, and those with mobility issues
  • Powerful dual flush uses less water while maintaining the same level of performance

The HOROW is a compact unit: it has a 12’’ rough-in, but measures only 25’’D x 13.4’’W x 28.4’’H and has a round bowl, which makes it a good pick for those who need a comfort height toilet for the smaller bathroom. 

However, this space-saving toilet packs a really powerful dual flush with siphon jet action. The partial flush uses 1.28 gallons, and the full flush creates a cyclonic whirlpool with 1.6 gallons and removes all the waste through a glazed trapway.

What to Look for When Choosing the Comfort Toilet for Elderly or Tall People?

Bathroom Space

If you want to make your bathroom more accessible for tall or elderly people, you need to consider things in general. 

Aside from choosing the height of a toilet seat, you also need to properly measure the space around the loo so that everyone will have free access.

So, the International Residential Code (IRC) suggests that the toilet should have a 21-inch clearance in front of it. Well, this might be a bare minimum for a small bathroom, but some home improvement groups, such as National Kitchen and Bath Association (NKBA) recommend at least a 30-inch clearance, especially if the commode will be used by seniors (2).

Bowl Shape

One of the main things that make the toilet for tall people convenient is the extra leg space. Commodes with an oblong bowl can provide that extra space, and that’s why most users prefer them. However, if you need a toilet for small spaces, you can choose a round bowl that runs 2-3 inches shorter, or go for the manufacturers that offer compact oblong bowls.

Flushing System

Toilets with gravity-fed systems are more common because of their straightforward maintenance and quiet operation. 

However, if you need extra pressure for a more efficient flush, you can choose a pressure-assisted unit. It blasts the water into a bowl similarly to blowing it through the straw and ensures better waste disposal and bowl scrubbing. Note though, that pressure-assisted toilets tend to be noisier than gravity-assisted and may require more advanced knowledge if you encounter the need of fixing them.


Water conservation is an important thing, and when it comes to household water use, you can significantly reduce the consumption by purchasing a water-efficient toilet.

Here are the most reliable certification programs:

  • EPA WaterSense. WaterSense is curated by the US Environmental Protection Agency. This program checks all water-using appliances, including lawn sprinklers and irrigation controllers. Using WaterSense certified toilets can save you up to $110 per year in water costs or about $2,200 during the lifetime of your commode.
  • CALGreen. CALGreen is the California green building standards code. It was developed in 2007 and is used until this moment to ensure that all new residential buildings meet the energy-efficient and water-saving standards. Note that not all CALGreen approved toilets may meet the WaterSense requirements and vice versa.


The standard height toilet measures 15 inches from the floor to the top of the seat. Comfort height toilets start from 16 inches and go up to 21 inches, just like the average chair.

Toilet seats come in different heights, but generally, if your toilet has a 16-inch bowl, you can accompany it with any toilet seat.

Yes and no. ADA compliant toilets can sometimes be labeled as ‘comfort height’ but the maximum height allowed is 10 inches. Comfort height toilets have a bit more room to expand and can include 20-inch or even 21-inch high seats, which may not comply with ADA.

Yes. If you need a toilet for tall people, comfort height is your go-to option. Just be sure to choose units with at least a 17-inch high seat, so the person can feel comfortable.

Yes, many comfort height toilets are designed for smaller bathrooms. They can have a shorter rough-in and a smaller round bowl that will occupy less floor space. Or, you can opt for a corner comfort height commode with a triangle tank.
