Bath Fans by Room Size Buyers Tip: Choose a fan that can move at least 1 CFM per square foot of room. For example, for a 50-79 sq. ft. bathroom, select a fan with a 50 to 80 CFM rating.
Bathroom exhaust fans are sized and rated by their ability to move air in cubic feet per minute, or CFMs. Smaller fans generate less CFMs, so the less powerful fans are ideal for smaller bathrooms because they need to cover a smaller area. Higher CFM bath fans work better in larger bathrooms.
The bathroom ceiling fan may be nailed or stapled to the ceiling joists. Mine was stapled at the wings on either side of the fan housing. To figure out how it was fastened to the ceiling joist, I worked a flat head screw driver between the fan housing and 2×10 wood joist to locate the fasteners.
By code, a bath fan must vent moisture to the outside, ideally through a duct to the roof or, as shown here, through a gable wall. In cold climates, use insulated duct (above) to guard against condensation in the duct. Zip-tie the duct to the fan's exhaust port and to the exhaust vent, then seal the connections with foil tape.
