We have very recently had our bathroom completely tiled (our first major house treat ) and as usual are doing things a bit back to front, we know we should have had a fan fitted but didn't, and now want one. Would whoever fitted it be able to drill through tiles, I would hope the fan would be fitted next to airing cupboard, obviously on outside wall and there would be hardly any channeling out as wiring would go straight into cupboard. Also can anyone recommend what they feel would be the best type to buy, never had one before so haven't a clue and would this be a straightforward job for the electrician. Any views welcome.
