bathroom venting under a cantilever and
I’m hoping someone can help me out here. I have an older split level house with a downstairs bathroom that does not have a fan. The entire house has a 2 foot cantilever and there is a deck attached to the house above the bathroom.
I want to install a bathroom fan and am wondering if I can install a wall fan. It would vent out about 1 1/2 feet below the cantilever and deck joists. I live in a northern climate. Will the moisture have enough room to evaporate before condensing on the cantilevered floor above and deck? If I use a conventional ceiling fan it would vent directly into a deck joist bay.

Just so you'll know (and maybe you already do).........
If you vent the f-ar-ts out below the deck, and you have a summer party at your house, the guests on the deck won't have a very good time.
I won't be laughing at the lies when I'm gone,
And I can't question how or when or why when I'm gone;
I can't live proud enough to die when I'm gone,
So I guess I'll have to do it while I'm here. (Phil Ochs)
It's more the moisture from 3 teenagers I was trying to get rid of. Don't you know teenager's xxxx don't stink?
Use a Panasonic ceiling fan, wire it to the lights so that the boys can't forget to turn it on. Primping in front of the mirror will give enough time to clear out the moisture. The Panasonic fans are very low sones.
Vent it thru the joists and then down out the cantilever. Moisture will not be significant issue. Cleaner look than a wall fan, less drafty.
If you are opening the cantilever, think about opening the whole thing and upgrading the insulation with foam board or spray. Since you are also in a northern climate, use foam that will give you a combination air and vapour barrier. I did this with my home last fall - 3" of foam board vertical in the bay and caulked to form an air barrier, 3" flat up to the floor boards, remaining 6" of cantilevered space with fibreglass.
Thank you, very helpful advice.
