Also known as disabled toilets, accessible toilets, handicap toilets and/or comfort height toilets, ADA toilets are designed to address the inconvenience bought by disabilities.

  • A raised toilet seat for easier sitting and standing for the disabled
  • Tool-free removable arms, for more flexibility for users
  • Added height – there is an additional 17″-18″ over a standard toilet
  • Wider space to accommodate a full-size adult wheelchair and movement within the stall
  • Special colored toilets, which help color blind people

ADA Toilet Height vs Regular

The height of ADA compliant toilets is higher (2-3 inches) and spacious regular toilets are shorter and with less space. Handicapped toilets have additional features like removable arms while regular toilets do not. Most regular toilets are white. Some ADA toilets come in special colors for visually-impaired people.

What to Consider when Choosing Toilet Height

To wind up, here are some factors to look into if you’re not sure what height measurement is right for your new toilet.

1. Users

As mentioned earlier, comfort height toilets are more prevalent than the standard toilets, probably because they serve a greater population than the other.

Either way, they allow for easier sitting and standing, regardless if you’re not physically challenged, aged, or tall.

This, however, doesn’t mean that standard toilets aren’t common. They are an excellent choice for kids as you won’t require to purchase a ladder or step chair for them to use.

2. Height Measurement Requirements

The ADA compliance act under exception clause 604.4 states that the recommended height for persons with a disability requires two to three inches taller than the standard height of 16 inches. This is the measure from the floor to the toilet seat.

This then qualifies comfort height toilets to be used commercially or universally since they cater to more individuals.

Standard height toilets are best for home use, where if you need additional height, you can invest in risers, arms, or paddles, among other seat raisers.

3. Appearance

The main differentiating feature between these two toilets is simply the height. That being said, design and coloring are available in a variety for both, although white is the most common shade.

Also, the two wash sets do come in different designs from a one-piece to a two-piece.

However, the one-piece can be rather expensive to purchase, which adds more financial strain, especially for the regular height toilets since they are occasionally more costly than the chair height type.

4. Sitting Position Constipation Issues

Standard toilets are thought to enhance bowel movements hence preventing constipation and hemorrhoids. This is because the hips will be well-positioned below the knees.

Because the ADA complaint toilets are taller, they offer a 90-degree seating angle. This position is good for the knees and back; especially for the aged, tall and people with mobility issues.

However, some health experts claim that the chair-like posture inhibits natural bowel movement.

5. Cost

Finally, the budget price for these two toilets. Comfort height toilets cost between $100 to $300 depending on your preference and brands such as TOTO, Kohler, and American Standard.

As for the standard toilets, they can cost you between $200 to over $400. The best brands for these kinds of wash sets include Drake, TOTO, and American Standard.

Which height is best for you?

Whether the toilet is identified as standard height or chair height, the best toilet height will depend on the user. It should be one that allows you to easily sit down and stand up.
