Im doing a bathroom shortly and have been asked to include an extractor fan, there is a vent grill (masonary) already in the room above an electric shower which is coming out (replacing with bath mixer tap shower at other end of bath so no risk of water in this area in future).
The current shower is switched from a pull cord in ceiling nearby.
So I'm thinking, remove tiles around the vent, chisel off vent facing,duct if necessary with some 4" pipe, use supply for old shower, replace breaker in consumer unit with a 5amp, fit fan, bobs your mothers brother ?
Any advice or hints and tips much appreciated
