Here is a different approach to handicap toilets. The Universal Toilet is a flexible toilet design, by Changduk Kim & Youngki Hong, useable by both individuals with disabilities and the general population that removes the social stigma of handicapped facilities.
For users with disabilities, even a dedicated handicapped toilet requires maneuvering, especially when in a wheelchair. With the Universal Toilet users don’t need to turn or twist but can simply slide forward off the wheelchair directly onto the toilet. There is even a chest board to lean against for added stability and comfort. Handles on the chest board can also be of use when standing or transferring between the wheelchair. For other users, the chest board becomes a backboard to lean against.
The Universal Toilet is also very space efficient, requiring only a quarter of the space of existing handicapped toilets. And since the toilet’s sleek, curving forms are like nothing seen before, users with disabilities need no longer feel self-conscious.
