Handicapped person needs a shower but the handicapped bathroom she has is too small for a shower. It was build in her dinning room for her use. it is a 5x7 ft room. with a commode and sink and room to get her wheelchair. She needs a shower. I say make the bathroom a shower by tile the walls and putting a drain in the floor. Put grab bars and a handheld shower and a shower bench for her to transfer to.. Can that be done and any suggestions?
