What do you think about Japanese style bathrooms?

My question really has to do with the tub and shower for a master bathroom. When I was in Japan I really liked the bathtub in the wet area with the shower. When you step out of the tub you are basically in the shower are still. You can enclose the entire area in glass or with a wall. In America we tend to put the bathtub in a place of prominence in the grander of bathrooms, directly in front when you walk in the bathroom.

Also, Japanese soaking tubs are usually shorter, but deeper, so more of your body is immersed, and you are in more of a sitting position than laying down. Any thoughts on that? You can use a standard American style tub or soaking tub in the “wet area” set up.

I’m interested in your opinions. Would having the tub in the shower room turn you off if you were buying a home?
