Design requirements for handicapped toilets for disabled are governed by the rules of accessible design, ensuring that disabled toilet facilities are available and usable for whom ADA (Americans with Disabilities Act) needed. These requirements are to be applied throughout the design, construction and alteration of buildings and facilities.
All bathrooms in new buildings including handicapped toilets must provide at least one accessible toilet for handicapped having an accessible route. The minimum width of a standard bucket is 60 inches. A sidebar grip should be 33-36 inches above the finished floor. Where available six or more positions, plus an accessible stop, at least one seat 36 inches wide and equipped with an external-balancing, self-closing door and parallel support bars on the side walls is required.
