We live in a suburb of Minneapolis. Our master bedroom has a decent amount of unused space. My wife really wants a steam shower. Rather than remodeling an existing bathroom, I've started thinking about adding the steam shower to our bedroom.
Steam showers are enclosed and well-sealed to keep the steam from escaping until you get out. Many of them also seem to be more-or-less freestanding, and don't need to be fixed to the floor/walls to the same degree as a normal shower/tub.
Bathrooms of course have special code requirements around ventilation, electrical, etc.
I'm wondering what kinds of things we would need to think about in order to plan this project. For example, at its simplest could the steam shower just be installed in a corner of the bedroom? Or does it need to be walled off with its own door/HVAC/etc?
