The height of a toilet is measured from the floor to the seat. And toilets come in two height categories that are standard and comfort. The standard toilet height measure from 14 to 16 inches. While comfort height measures 17 inches and above.

Toilets are manufactured in different sizes and according to the needs of every individual. That’s why it is vital to consider the right toilet height for your bathroom. And as a matter of fact, you don’t want to stick to a toilet that is not comfortable.

So stay with us for more details on “what is the tallest toilet you can buy?” for your bathroom.

Standard Height VS Comfort Height

As mentioned before, toilets are manufactured with two height options that are either standard or comfort height. Let’s look at the difference between these two separate sized toilets, their benefits, and drawbacks.

Standard Height Toilet

The standard toilet height is measured from 14 to 16 inches, maintaining a low profile. It is suitable for children and short heighted people. But it is not very ideal for taller people as it doesn’t provide a comfortable sitting posture.

Comfort Height Toilet

Comfort height toilets measure 16 ½ to 20 inches. The taller height of this toilet provides a comfortable sitting position for taller people and those with disabilities. It is easy to sit and get up at this height without any support.

The comfort height is also known as chair height or handicap toilets. There is often a debate on whether tall toilets result in restricted bowel movement but let’s just leave that for now because of the split decisions. But one thing for sure is that taller toilets are not comfortable for children and people of short height.

ADA Compliant Toilet

Through American Disabilities Act, a toilet must be 17 inches or more from the floor to the seat. The comfort height falls in the category of ADA-compliant toilet. This height is suitable not only for those with disabilities but also for elderly and tall people as well.
