Toilet Height. Whereas the height of a standard toilet is 17 inches or lower -- 14 1/2 inches is a common height -- the ADA guidelines mandate a distance between 17 and 19 inches from top of the seat to the floor on a handicap-accessible toilet. If the toilet is for use by children, the height must be from 11 to 17 inches.
