Exhaust fan placed in the floor?
We have a half-bath without any exhaust fan (it has supply air vent only). So it stinks on occasion. We'd like to install an exhaust fan, but the half-bath is located in the middle of the first floor, and there is absolutely no way to vent it outside through the ceiling (long to explain why but really, no way)
The house is pier-and-beam though, and it would be very easy to install the exhaust fain in the floor and vent outside of the house by running the duct vent through the crawl space under the house (this is how our dryer is vented, it's located in the room next to the half-bath).
Do you know of any code such floor-installed exhaust fan might violate? Have you ever done or seen a floor-installed exhaust fan?
