Panasonic was one of the brands I was thinking about. which model did you go with?
I like the idea of a remote fan. Granted, it could realistically only be put about 10-15 feet away from the bathroom (house is only 1250sqft ranch) but that could be sound deadened more - and possibly run an exhaust for the kitchen stove as well (there is no hood now).
The other thing is that I dont want to cut a hole in my rather old but in good shape fiberglass shingles. And there are basically no eaves. I could
vent it over the front porch where it is open for ventilation
My other option is to just run it up to the ridge vent and push it out there.
