Walk in Tubs

I work around elderly people quite frequently and I see how hard it can be for them to get around to do their daily activities. I sometimes wonder how they can get themselves in and out of their bathtubs without assistance. So, then I think about walk in tubs and how nice they would be for people like this. I'm not that old and I know I would enjoy one. This is a great idea for anyone who does need help getting in and out of a tub.
