I have a bathroom with a shower that has no exhaust fan, and I'm trying to install an exhaust fan and ducting. The question is where to the ducting should vent to the outdoors. The simplest thing would be to run the ducting through the ceiling to the exterior wall (a 4' long straight run), where I'd install a louvered outdoor vent cover (as for a dryer).
I'm wondering if it is an issue that this spot on the exterior wall is inside an open eave. I'm including a photo of the exterior wall. where I've marked the spot where the vent cover would go in red. I'm also including for reference a photo of the exterior wall from another angle, as well as a photo of the other side of this wall from inside the bathroom.
Is it a problem that the warm humid air being vented from the shower might accumulate in the open eave under the roof?
Relatedly, there is a rectangular screen-covered hole where this new vent will go, which I expect is there to provide ventilation to the small attic space (which is just the 8" height of the joist - the house has raised ceilings). Since the new vent would cover part of this, do I move the existing attic vent to the side, or do I remove it altogether in order to avoid having moist humid air enter the attic space?
If it is a problem to have the new bathroom fan vent into this spot on the exterior wall of my house, the other option would to be have it vent through the roof.
Thanks in advance for any help with this!
