I'm currently refurbishing the dowstairs loo which has no extractor fan at present. I've already sussed out the wiring etc. (thanks to electrical forum). By far the best place to put the fan, in terms of cable routing and access to outside wall for venting, is in the wall of a large cupboard built into a recess at the back of the room.
The whole room is only 4' by 2'6" and the cupboard is 2' deep by 18" wide by 5' high.
Does anyone know whether it would be permissible to install the fan into the cupboard with an appropriate ventilation grille fitted between the cupboard and the toilet? This is a normal wall-mounted fan NOT an inline one, so would need to draw air initially from the cupboard, relying on the grille to carry the airflow from the toilet into the cupboard. I can't see any practical reason why the arrangement shouldn't work (the cupboard has no other openings to act as air inlets so would have to draw air from the toilet). I really just want to know if there are any regs which demand that the fan is placed directly in the room to be ventilated.
