I have always preferred a bath and can still use my bath, get in and out of it, it’s the sitting down and getting up which is the problem.
I flop into it, so keep the water a few inches high as I make a huge splash, and run the extra water in. When it’s finished I turn around onto my knees and use the sides of the bath to help get me up.
My nightmare is that one day I will get stuck and have to be winched out by the fire brigade….
I don’t know how long this can continue, or whether I should bite the bullet and get a shower in rather than leave it too long and have to deal with all the mess a new-bathroom makes.
