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.
Our house has wall vents for all 4 bathrooms, so it's definitely something allowed by code here. It works just fine, there are louvered exits on each one. It's better than venting into the attic like a lot of older houses for sure.
