tallest toilet for elderly

Commodes come in different types, colors, shapes, and most importantly, heights. Yes, you read that right—we have various toilet height options to meet our needs, such as the elderly.

Standard toilets typically stand 14 to 15 inches high, but the tallest toilet for the elderly is 21 inches from the floor to the rim. We can get this from brands like Signature Hardware and Convenient Height Company, although Kohler has a 28.5-inch tall wall-mounted toilet.

Purpose of Tall Toilets for the Elderly

While many of us have no problems sitting on and getting up a toilet, those with weakened bones and joints—especially in the hips, knees, and back—may find it a pain (literally). While there are toilet risers, not everyone prefers this option.

Hence, to promote equal opportunities to use commodes comfortably, the Americans with Disabilities Act (ADA) made the 17 and 19-inch toilets possible. These are known as tall toilets for the disabled and for tall people who find it difficult to squat too low.

However, almost all the ADA toilets back then were 17 inches tall until these years when extra tall toilets were released by the following companies:

  • Convenient Height Company 2016: 5” from floor to rim, 21.5” including the seat
  • Signature Hardware 2018: 18” from floor to rim, 19” including the seat
  • Signature Hardware 2019: 21” from floor to rim, 22” including the seat

Kohler also released its 19-inch toilet after these two brands. There was no specification on its seat height, but we can assume it to be an inch.

Things to Consider Before Choosing a Tall Toilet for the Elderly


1. Height

Taller toilets for seniors come in different heights, so you have to determine how high you need your commode to be. We recommend choosing one that lets you place your feet flat on the ground so you would have no trouble with balance and getting on and off the commode.

However, also consider your height; a toilet that is too high may not be comfortable if you’re short. Mobility issues are also a factor in whether you need a taller toilet to be more comfortable.

2. Shape

Senior height toilets also come in elongated or round. Elongated commodes are deemed more comfortable for people with mobility issues, because of the wider space to seat.

On the other hand, round toilets save more bathroom space and may be more pleasing to others, appearance-wise.

3. Type

A standard commode can have a 17 up to 21-inch toilet bowl height (22 inches including the seat). These are floor-mounted toilets that belong in the comfort height category.

However, we also have a wall-mounted toilet that can go as high as 28 inches such as the Kohler Veil K-6299.

Choosing between the two will depend on your preferences and weight; floor-mounted ones can carry 1000 pounds and wall-mounted ones, 500 pounds.

4. Water Efficiency

Almost all of the new models of toilets are water efficient, abiding by the 1.6 gpf (gallons per flush) in the plumbing standards. Some models can go as low as 1.28 gpf and even 0.8 gpf for flushing liquids.

Installation Costs of Tall Height Toilets

On average, we can expect toilet installation costs to be more than $250 up to $900. This does not include the cost of the toilet itself.

The price for installing a toilet will depend on the following factors:

  • Area – The national cost of living and standard wages in a state or province may affect plumbing costs. For example, the hourly range can be between $65 to $125, which can still go higher for an emergency visit.
  • Type of Toilet – The type of commode whether one-piece, two-piece, or wall-hung contributes to the installation costs because they affect the amount of work to be done.
  • one-piece: $100 to $300
  • two-piece: $200 to $300
  • wall-mounted: $400 to $900
  • Amount of Work Necessary – We also have to pay for the skill and amount of labor spent in a specific period. For example, an old toilet may have to be removed or other plumbing problems need to be addressed.

The need for a new plumbing system is also present if there were no previous bathrooms in the place of installation.

Frequently Asked Questions (FAQs)


What Is the Tallest Height for a Toilet?

The highest toilet height for floor-mounted commodes is 22 inches with the seat included. Only the Signature Hardware brand has a toilet this tall, particularly their Bradenton line.

Tall Toilets and Raised Toilets: What Is the Difference?

Tall or comfort height toilets are commonly manufactured to be higher than the standard height which is 15 inches.

On the other hand, raised toilets are standard-height toilets—14 to 15 inches tall—that use separate equipment called “raised toilet seats” on top of the actual manufactured seat.

They are both created to provide comfort and accessibility to people with mobility issues such as the elderly, physically disabled, people with weakened bones and joints, and tall individuals.

Commodes should be accessible and comfortable to everyone, especially those with mobility issues. Hence, adjustments to the standard toilet heights were made, and the tallest toilet for the elderly is 21 inches from the floor up to the rim (22 inches including the seat).

Some of the brands that we can get an ADA-approved 17 to 19-inch tall toilet include American Standard, TOTO, and Kohler. If we’re looking for extra-tall ones that go as high as 21 inches, we have Convenient Height Company, Signature Hardware, and Kohler as well.
