What is the standard size of a small toilet?

The standard size of a small toilet bowl is 14 to 15 inches from the floor. Larger toilet bowls are about 16 to 19 inches from floor level. Though models vary, one example of a toilet dimension from Lowe's measures 29.5 inches deep, 19.5 inches wide, and 14.5 inches tall.

The circumference of a toilet depends largely on the style and shape of the toilet. There are single-piece and two-piece models of small toilets to choose from. The smallest toilets are those that are attached to the wall, which are best for compact bathrooms. The toilet seat size depends on the size and shape of the bowl.
