Grab bar in alcove tub
For our bathroom remodel, we are planning on putting a grab bar in the alcove tub/shower area. We are in our 50s and it may be useful at some point - in the meantime it is another place to hang a washcloth. :-)
There will be two niches on the long wall, one at showering height for shampoo, etc., and another at bathing height for soap and other bathing (versus showering) supplies. We will also have a corner soap dish at showering height. The grab bar will be just above the lower niche, at the level shown in the below photo.
My question is, what length should the grab bar be? Given that it will be on the long wall, just above the lower niche, I think probably 24" (not 18"). I'm interested to know what others have done.
