The house we moved into has a finished basement. There's a bedroom with a half-bath, but no windows and no fan. I believe that's a no-no, code-wise. But, more importantly, we have people who stay there from time to time and I'd like to add an exhaust fan.
The problem is there's no place I can think of to put the exhaust. The bathroom is in the corner of the house and the two outside walls are concrete and below ground. Is there any such thing as a filtered fan, something like for kitchens? I could exhaust into the utility closet, where the well tank, water heater, and other plumbing is located. But I don't want the odors moving out into the family room. And my father-in-law can be aromatic.
Or would a kitchen-style fan exhausting back into the bathroom be enough?
Thanks.
