My landlords put in a walk in shower for me this past summer. It also has a seat on each end. I feel so much safer in it than the old shower/tub. It does have about a two inch ledge so if I could not lift my legs, it would be a problem. I did fall backwards into my tub last Spring from the floor.

I got dizzy and tried to grab the rod which fell also. Luckily, there was no major damage.
