Hi,

Want to put in an extractor fan in our bathroom. What to run flexible hose up through the loft, then knock a hole in the side of the wall in the loft and put a vent in.

Can i put the extractor fan anywhere on the ceiling of the bathroom or is there rules, i.e not directly above the bath???

any suggestions for knock the hole in the wall, was gonna stitch drill then chizel.

..and keep browsing;)

The Wickes freeby guide to Home Electrics is very good in describing the Zone system for bathrooms - but the .pdf on their web site hasn't got all the diagrams in it. You'll have to go into one and pick it off the display (usually just inside the door)

You could always vent out of the roof.
I've two fans fitted (main bathroom & ensuite) one vents out of the wall and one through a roof tile with a cover vent over it.
IMHO - Both fans are placed in the best possible position - directly over the smell factory outlet :D

The extractor is not for toilet smells really, its for steam removal from showers. We have crappy single glazing and the steam from the shower sticks to the window and runs down and the whole bathroom feels all damp and horrible. Yes we do open the window to start with but its not enough.

Was hoping an extractor fan would help.

Which is easier then, to put the outlet vent in the roof or drill a hole in the wall ???

So can i put the fan anywhere then, i.e right over the shower ??

cheers

I've fitted a shower in a cubicle into one of the lad's bedrooms. His has a shower fan from Screwfix, which comes on when you switch on the shower, and runs for 2 minutes when you switch it off.

I vented it out through the ceiling, (it also has a halogen low voltage light in it), and across the loft floor, and then out via the soffit, (which IIRC is the bit that is horizontal below the eaves?)

Shower fan is mounted above shower, and outlet has a fine-ish alloy mesh on it against insects.

was thinking of using a vent with flaps so it only opens with air pressure from the fan.

Not sure about venting throught the sofits as the bathroom is not at one the ends of the roof its on the side, so the sofits are going upwards at an angle.

so above the shower is where its going then, thats that one cleared up, just need to decide on the venting

Cliff

LOL - My fans are for steam, its just that I use them more for smells :D

The vent cover on the wall is the flap type and to be honest it was a waste of time.
It kept jamming and when free would constantly open and shut in the wind keeping us awake at night with the tapping.
I tried to stop the noise with that spongy tape ( for sealing gaps in doors etc) but after another 2 nights of no sleep, the flap was ripped off and thrown away leaving the cover to stop rain water getting in.

So then what would you recommend for a vent and where should i put it. Bearing in mind I have no ladders so would have to borrow some. So i am looking for a method that is easy-ish to install

Cliff

I'd recommend trying to use the eaves / soffit.
Dont bother with expensive vents, try attaching the pipe so it goes through the soffit board (ie points down) then cover the opening with a bit of plastic mesh, paint and you'll never know its there.
If you do exit via a wall then buy a vent cover as it will keep out the rain but do as I did before you fit it and take out the flap and replace with plastic mesh (keeps insects out etc).

P.s. My fan blades are closed when switched off, so cold air can't get into the house - maybe worth a thought when looking at which fan to buy.
