I think I saw something like this once on TV. I believe it was on a show like House Hunters (might have even been that show). A woman was looking for a new home for her and her kids. I could have sworn the master bathroom had something like this one: http://www.showerstallsinc.org/aquapeutic-U689w-bathtub-shower-stall.html
Honestly... It looked kind of silly. It really stood out and looked a bit like an alien spaceship. lol I'm not saying that it's not cool and has interesting features but like you said it is a lot of money. Make sure to consider resale as well. YOU may love it but someone else may not. Might drop the value of your bathroom to some people.
Post more info if you go for it!
I have been looking to remodel my bathroom and I found these computerized steam showers. They have radios a whole bunch of features built in what do you guys think? http://www.showerstallsinc.org
If anyone has bought on or has a friend that has I would really appreciate their experience because its a pretty expensive purchase.
