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?

" it looks like quite a job to get electric there"

Could you elaborate as to why you believe this to be the case?

In case you had not already considered it, you can surface-mount an electrical raceway/conduit. Eliminates cutting and snaking wiring inside walls. But, really, with drills and fish tape you can retrofit wiring in just about anything.

Your issue would tend to be more about locating the actual fan itself. You want to locate them up high because warmer air rises and warmer air can contain more moisture. Wall penetration to the outside might be your best bet: I'd think that it would mean having a box sticking out from the wall. But...

Fans are mostly used to remove moisture/humidity (and odor to a degree). A dehumidifier can do that job/work.
