Standard size of toilet

Answer 1

Standard height is 15" but you can get comfort height or ADA models which are 17" high. The standard toilet rough in dimension is 12", which means the outlet of the toilet at the floor is 12" from the unfinished wall, but they do make 10" and 14" rough in models. The width really depends on the type of toilet you get but remember International Plumbing Code requires 15" from the center of the toilet to the nearest wall. Hope that helps.
