Bath fan location

user-1105327 | Posted in General Questions on

is it advisable or best practice to install the bath fan directly above a walk-in shower or bath tub? often you see them directly above the water closet but in terms of removing moisture from the bath or shower, wouldn’t it be better served as close as possible..? thanks

    The main problem with locating a bath exhaust fan in a shower stall or above a tub is that the location is so humid that it can cause steel parts of the fan housing to rust. I think it's better to locate the fan in the ceiling, just outside the bath or tub area.
