What is a Compact Toilet?

A compact toilet is smaller and takes up less space than a standard size toilet. Often, compact toilets have round bowls instead of elongated bowls to be closer to the wall. Some models feature small water tanks and seats. Other models can be mounted directly to the wall, saving the need to have a large tank attached behind the seat. Since there isn’t a universal standard for the size of compact toilets, there are a range of sizes available that would be considered compact.

What is the Size of a Small Toilet?

There is not a universal size requirement for a toilet to be considered a compact size. However, standard size toilets often run as big as 30” deep, 32” wide, and 32” high. Compact toilets can be 25” deep, 13” wide, and 28” high. The difference in space between a round and an elongated toilet is often 2”.

What is the Most Compact Toilet?

The smallest toilets are made for RVs, campers, and tiny homes. With these models, the toilet is often mounted directly on the wall and sits just 24” deep and 14” wide. While these models are probably the most appropriate for very small spaces, some people may not be the most comfortable relying on them for everyday use. People with disabilities or with difficulty getting up might have more trouble getting up from the 24” deep seat. However, these toilets could be the perfect match for a bathroom used by children or adults with smaller frames.
