Mom will move in soon

My husband and i recently visited my mother in law and the nursing center told us that she will be ready to go home soon but that someone will need to care for her since she can't care for herself. My sister doesn't have the room so i told my husband that we will have her move in with us. I'm worried about her while she's using the bathroom. She might fall or slip like she did in the shopping mall and had a stroke. My husband and i discussed adding some basic home bathroom safety products to prevent her from having an accident while in our home. We're hoping the cost of these improvements will go a long way to helping my mother in law live comfortably and happy yet safe.
