Want a new bathtub

For a very long time my wife and I have talked about getting our house ready for our old age years. One of the things that we want to do to prepare the house for that is to remove our old bathtub and install a new walkin tubin its place.  We’d love to get one that has a lot of spa-type jets in it, and a built in bench to sit on so that we can use it like a spa.  Also we’d like to have a shower head in it so that we could use it like a regular shower if we want to just take a quick shower.  I’ve always thought that having a walkin tub is a really smart thing because it makes it so easy for people to get and out with less hazard of slipping and falling down.
