My mother is 93 in wheelchair with limited eyesight. The bathroom she uses has shower doors right next to toilet. The shower doors have been in 8 years and now need adjusting. I am thinking of replacing with rod and curtain. It is a step in shower no tub. My friend says to fix doors as if she grabs curtain she will fall. I am afraid she will fall thru doors. Any advice on how to make it safer for her?
