No heated floor. We could have, but it would have made putting in the waterproof underlayment just that bit harder and possibly more likely to develop leaks. The whole thing is made to be waterproof and the tub made to overflow, and because its wood you clean off before you get in, so the floor should be warmed by the water. I can't get to it right now (it's in a very large cardboard box…) but the tub is quite similar to this one.
I know what you mean Emily - I grew up on the east coast and it feels like everything there is so much older. The craftsman style houses out here were already quite influenced by Japanese architecture, so the style usually fits in quite nicely.
