I dunno: all I can think about with that bathroom is what all the humidity and moisture will do to the wood if you actually try to use that bathtub regularly.
I had a house that had a nice soapstone(?) tile motif on the rear bathtub wall in the master bathroom, and if you didn't regularly seal it, over time the moisture seeped into the stone and disintegrated it. Major pain I was glad to be free of when I sold the place.
There are lots of ways to make wood waterproof, people have outdoor wood decks in rainy and humid climates after all. In tandem with a solid ventilation system it shouldn't be so bad.

Where I am in soggy WA I have to re-seal my wood deck every year or two or it starts to rot.
There are ways to make it more waterproof than that, but it's not always done; and I would probably have to rip out the entire deck to make it so.
