Short List
This bench opposite the shower head. Long cubby (two?) with long grab bar under it centered in back wall. Two show heads, one high over headend another on pole adjustable and removable as a handheld to be used by John or someone on the seat. So possibly with an extended cord. Long drain along the shower edge. With a curtain that can be pulled closed to protect the rest of the bathroom. White tile with blue and maybe yellow accents.
Shelf up high? Cute!
Lower cubby for John to access
Corner shelves?
