Building a Steam Room

Hi all - I'm new here. Great group, lots of good advice.

I'm in the process of redoing a bathroom and decided that I'd like to add a steam bath to the shower area. While I know I can purchase a steam unit and will have the appropriate wiring and piping done by the pros, I've got a question regarding the venting of the space when it's being used as a shower and not a steam bath. My family is concerned that we'll be building a shower area and closing it off with a glass door. Their concern is that when they shower, the space will not vent any of the steam genrated from just the shower. (In order for a steam bath to be effective, the space must be sealed.) So, what type of venting for the shower would aleviate their concerns? Would a ceiling fan do the trick, even if it's an entirely closed space?? Or do I need to add vents at the top fo the door to allow regular steam to escape?

TIA, Sandy K.

I've been pondering the same question.

I was thinking of putting a standard vent fan just outside the shower/steam door and venting after I am done by leaving the door ajar. If you left the steam in the sealed room, it should not do any damage if it were constructed well but the slower drying time of the space might promote mold/mildew necessitating more cleaning. All of the diagrams and examples I have looked at do not have any venting directly inside the room but I don't see any reason you cannot.

There is no difference between steam made by the shower and the generator. One dealer recommended that I have a 1-3" space above the door anyway. In his opinion, it made the space more comfortable (breathable) and allows for the passive venting your family wants.
