Next question, I'm remodelling my bathroom at the moment with a walk in shower. Should I get a standard type extractor that exits through the wall, or an inline one that's in the loft?
Inline every time. They're quieter and extract a much greater volume of air / moisture. Also worth considering hooking it up to a humidistat instead of a timer as this will solve many, many problems you may have with moisture in the house.
@Bobbo & @rhowe thanks both, will check them out.
