TOTO Toilet Height: Standard or Universal Design

Choosing the right toilet isn’t only about style or flushing performance. Toilet height plays a big role in comfort and everyday use. When shopping for a toilet, especially a TOTO toilet, you’ll often see two options: Standard Height and Universal Height.

This guide explains the difference so you can choose the best option for your home.

What Is a Standard Height Toilet?

A standard height toilet measures about 15 inches from the floor to the top of the toilet seat.

This height has been common for many years and is still preferred in certain situations.

Standard height is a good choice if:

Your household includes children
You prefer a lower seating position
You are replacing an older toilet and want a similar feel
The bathroom is used by people of shorter height

Many homeowners still choose standard height for secondary bathrooms or powder rooms.

What Is a Universal Height Toilet?

A universal height toilet, sometimes called comfort height or ADA-compliant height, measures about 17 to 18 inches from the floor to the top of the seat.

This height is closer to a standard chair, making it easier to sit down and stand up.

Universal height is ideal for:

Taller individuals
Older adults
Anyone with knee, hip, or mobility concerns
Households planning for long-term comfort and accessibility

Most new TOTO toilet designs are offered in universal height because of its broad appeal.

Standard vs Universal Height: Which Should You Choose?

There is no “right” or “wrong” choice—it depends on who will be using the toilet most often.

Standard Height feels familiar and works well for children and shorter users
Universal Height offers easier movement and added comfort for adults

Many homeowners choose universal height for primary bathrooms and standard height for guest or children’s bathrooms.

TOTO Toilet Height Options

TOTO offers both standard height and universal height toilets across many of its collections. This allows homeowners to choose based on comfort needs without sacrificing design or performance.
