Ceiling extractor in bathroom

Beara102

Hi,


I have a problem with paint peeling and flaking off in the bathroom. I've been advised that it's probably due to moisture from the shower etc. and installing an extractor in the ceiling should help; is there an ideal location on the ceiling for the extractor.


Any advice appreciated.

Anywhere above the shower basin.

And it's best vented out from the attic space.

Get a decent one, say 5", with back draught flap and a timer run on.
It will need to be low voltage
clarification: 10/8/2018 based on post 8
if installing as suggested in post 2 above the shower basin which is the best place for it, to comply with wiring regs.
it also needs an isolation switch outside the bathroom

Thanks for the replies. I made some enquiries today and what I'm thinking of going for is 5" in line fan mounted in the attic (to cut down on noise) with run on timer and vented to the outside through a vent tile in the roof.

Sounds about right, you can get humidity controlled fans so they don't rely on the lightswitch being turned on

Surely not a great idea to have fans coming on in the middle of the night right next to a bedroom.

Mains is fine. Why would it need to be low voltage?

You can get very quiet ones and they will only come on when they detect significant humidity - you can turn on the light to go for a pee without the fan coming on and if you have a shower the fan will stay on as long to bring the room back to normal

What’s wrong with just venting out through a wall?

Nothing. He is putting the fan in the ceiling so needs to vent out of the roof space. If near a gable out through the wall will be an option to vent from attic.

I plan to mount the fan unit on one of the roof joists away from the bedrooms which should cut down on noise. There's no external wall to vent through so have to go through the ceiling. Vent tile seems the handiest option.
