Pworley-
Yes! When we bought this house my first project was to convert a downstairs tub to a walk-in shower with heavy duty grab bars on three sides, a bench and a shower spray with a long hose.
Since then my wife has had three major surgeries and this shower has made a big difference, especially when she had balance problems.
I also installed a grab bar in our regular tub, and now I would not want to be without it.
