Thought about this when my grandmother was alive. They are nice, but expensive. It was more cost effective for me to install a walk-in shower (splurged, and turned it into a sauna as well!!) and a hot tub on the deck out back. Gram easily got in and out of both on her own initially, and the walk in shower made it much easier for her aides to help w/ her bathing when she got to the point when she needed help.
