So I’m planning out a bathroom remodel and part of that is replacing the vent fan because currently mine is just venting into my attic (no bueno). I know normally bathrooms are vented out through the roof but my bathroom is on an exterior wall so I was wondering if I could just vent it out the side of the house. I’m going to be ripping open that wall anyways and I would much rather cut a hole in the side of the house than run a vent pipe up through the roof.
Also I’m in Minnesota if climate is a concern.
Where I live,the majority of exhaust vents are placed on exterior walls. I don’t see why it wouldn’t work for you. Just be sure to have some kind of weather guard on there to stop rain getting in (basically, the slats on the vent cover should point downwards).
Prefacing this with I don’t know much about this stuff:
I just bought a house and the vent did basically this. Issue was it back drafted into the sofets and made the attic still moist and there was mold. Without knowing what you’re doing I think out the roof is the best.
I second this as one should be careful where you vent moist air. My dryer vent in the winter would draft up into my soffits as well and it caused mold. Instead of fixing the issue I just replaced my gas dryer with an all in one washer dryer that condenses the air into the drain pipe and pumps it into the drain.
Theres no sofets on my roof (only has like a 4" overhang) so that shouldn’t be an issue on my house.
I have a bathroom vent going through the wall. No problem at all, in Wisconsin.
The vent cover has louvers that close it off, plus a shroud covering it. Weather is not a concern.
I don’t know if it can work, but I know if you run it out too close to the roof-line it’ll just go in the soffit and mold up your attic anyway.
I live in New Hampshire, and our downstairs bathroom vents out the wall. It works fine!
