couple of suggestions...though specialized for one particular medical problem...when I inherited the house I retained several of the adaptations

Dad suffered from Parkinson's Disease, and I built him hand rails for the steps, tub, commode, and an assistance rail from his bed to the bathroom out of 1 inch galvanized pipe which he could handle better than the larger commercial handicapped rail

removed interior doors, and replace swing open door to bathroom with fan fold door (the disease makes it difficult to back up)... removed doors allowed more clearance for a walker/wheelchair

hand held shower "wand"...cut down a "bar stool" to sit on under shower
