Uppeydog,
if you are positioning a fan within a bathroom (shower room) please ensure that the Building Regulations are adheared to.
these supercede the wiring regulations within a domestic dwelling.
we, ( when we do domestics, and that aint often ) position the fans in accordance with the building regs, over a shower we use a SELV ( 12v) fan the power supply/timer unit is usually mounted externally of the room on the wall coupled with a triple pole switch disconnector, from the general lighting supply.
we do not, ever position a switch inside the shower room / bathroom area, unless it is a pullcord for the general light.
be carefull on this one as it comes under the infamous PART P regulations and is `notifiable` addition to the installation , unless you are just changing the fitting,.
PaulUK have you an abridged version of PART P?

( we try not to have anything to do with domestic dwelling works as they are a pain in the axx ).
