Friend of mine with CP has had approval for adaptions in her house they are going to put a wet room in and also a lift the lift will go from her front room up through the ceiling into the master bedroom directly above sounded pretty good to me when she explained it.
The modern ones now are about the size of a shower cubicle. Alternatively, the can go onto the outside of the house.
We had a friend suffer a number of massive strokes a year or so ago, and they are looking into this now, to increase the possibility to staying in their current house.
