I have only just seen this post so I'm sorry if I'm a bit late with the suggestions.
My husband broke his ankle and was not allowed to weight bear for six weeks. However, the hospital lent him a perching stool for sitting in front of the basin, a shower stool which helped enormously and I bought a waterproof leg cover for about �15, which may seem rather excessive for just six weeks but he has had a problem with the wound site and has had to keep the area dry for the best part of a year now, so the waterproof leg has had good use.
He was also loaned a toilet frame and seat to raise the toilet to make it easier for him to use and a wheelchair for outings.
Getting up and down stairs was a problem, but he managed it on his bottom and we put a grab rail at the top to help him get to his feet.
Good luck with the healing, it is no fun being so imobile.
