Trying to extract 2.5 metres...
Afternoon, all - I'm writing to try and get some advice on ventilating a 10ft x 8ft downstairs bathroom if possible. I'd be grateful for any help, as I want to make sure it's fit for purpose!
Here goes... My downstairs bathroom is 'land-locked', with nearest route to an exterior wall about 9 feet away through the kitchen. Fortunately I have quite high ceilings (11ft or more, big, old Victorian house) so I can live with a pipe extracting close to the kitchen ceiling.
The extractor will be going horizontally from the bathroom, through the kitchen and to the outside.
As the distance the expelled air needs to travel is about 9ft, I could use some help, after having conflicting advice from different tradesfolk...
What sort of fan (inline, continuous, etc) should I go for, and what size?
What size/type of pipe or ducting should I use?
Do I need a special exterior vent? There is a louvred one on theoutside of the house already that I'm hoping to pick up and use, to save any more brickwork.
Currently there is a bath, sink and toilet in there, but I want to install an electric shower to the bath. I only recently moved in and there was a mustiness to the room. It didn't smell damp, but was a bit 'muggy', somehow. There are no leaks anywhere, and running water through the bath and sink traps helped, but I think it just needs better air flow.
I'm hoping that, as the extraction will be horizontal with no turns, it should be easy enough to do if I get the right gear.
Thanks in advance for any help!
