Bathroom layout help - to steam or not?
We are completely redoing our old house, building the bathroom from scratch basically, so we can do pretty much anything we want. We are planning a freestanding air tub for two, probably 66 or 72 inches long, so that gives us a little less room for the shower, but it looks like we'll still be able to make it 60 x 42 (and can probably gain a few more inches on the width actually, and if we do a 66 inch tub, can probably gain a few inches lengthwise for the shower), which should be OK. We want it to be able to be used by two, though most of the time it will probably be only one of us using it. We would of course have liked to make it bigger, but it seems like this is the best we can do if we want it all.
We are thinking a normal shower head on the wall opposite the bench, a rain shower overhead, and a handheld on the long wall, reachable from the bench.
We are contemplating a steam shower, as the SO has pretty serious asthma and allergies, so think this would be good for her lungs. One concern she has though is that if it is fully enclosed, it would be stuffy when she is taking a normal shower, but I've seen some things where you can do a glass transom, so that seems like a solution. Also, of course, if we're doing the steam shower we need the full bench, which does take away from floor space.
But just generally looking for feedback on this design - this seems to be the best we and the contractor can come up with, but of course wanted to put it out there for any fresh ideas.
Please let me know any questions, and thanks so much for looking!
