Hi Team
This bathroom needs an extractor fan to reduce the amount of mould accumulating. The house is likely to be demolished and the land redeveloped in the next few years so a big investment in this solution is not planned. I thought I'd be able to find a wall extractor fan with built in light but these seem to be like hens teeth. There is a single three core cable running from the switch by the door on the other side of the room. There is no ceiling cavity.
I'd love some suggestions!
