The top of tall toilet's seat is anywhere between 16 and 19 inches above the floor, whereas a standard toilet seat is only 14 or 15 inches high.
Tall toilets are also referred to as comfort height, universal height or ADA compliant height. They are approximately the same distance from the floor as a typical chair. This makes it easier to get on and off the seat. Comfort height toilets are often selected by tall individuals, senior citizens and people with certain disabilities. The tall toilets meet the standards set by the federal Americans with Disabilities Act. However, their convenience is increasing their popularity among the general population.
