Again, this is something some insurance companies will cover if you get a prescription for it. However, I found it a huge asset to have in order to take showers without help.
2 legs of the bench sit in the tub and 2 legs sit outside of the tub. The edge of the bench extends over the tub so you could go from sitting on the toilet to sitting on the bench. Then you can turn yourself around into the tub. Once inside the tub, you can use the handle to help steady yourself and you can even sit on the bench if you need to. This really helped taking care of myself much easier.
