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.
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.
