Bathroom exhaust fan

Post by Riliathr » Fri Aug 09, 2019 1:47 am

Have an old house with no exhaust fan in the bathroom, and it looks like quite a job to get electric there and to fit the fan in the wall or ceiling. Looking for alternative avenues to take, does it really matter if the intake for the exhaust fan is on the ceiling/in the wall/in the floor? I was thinking of installing an in-line fan 2 floors below in the basement and running 3 or 4" PVC piping up to the bathroom (which is doable) along with the electric, but is this a viable arrangement?

Because heat and steam rise, the fan needs to be in or near the ceiling. The duct also needs to be as short as possible to maintain air flow efficiency, as well as minimize the amount of condensation of the moisture from the air stream before it is vented outside.

For these reasons, the fan needs to be located within the bathroom.
