Extractor fan installation - with a difference!

[rocky_robin]

Hello all helpful people.

I’m just wanting some advice. I’m just installing a entire new bathroom and will be installing a new extractor fan (doesn’t have one at the mo)

As you can see from the below drawing, the only place that the fan can be placed is up through the empty void above the bathroom and through the roof.

The only issue is that the fan will not be placed in the best place (i.e. opposite the window and not beside it!)

Now, I’ve read quite a lot of topics on this regarding the installation of fans and especially the Condensation Trap that is required. Where on earth can this trap drain off to, if there is no soffits nor vents nearby?

The slates that I have is original cottage style slates (small ones – approx in between A4 & A5 paper sized). I was looking at the slate vents from Screwfix, but no idea on the size of these (nor does the Sales people!). There is no Slate suppliers anywhere near me either!.

Whats wrong with going straight through the outside wall. Saves messing about with the roof.

I did mine, ( 150 year old house) same wall thickness as yours, you need a good core drill/bit and some large bisceps.

I put a xpelair condensation control extractor with timer and humidistat.

Went from water dripping off everything after a bath or shower to dry as a bone at all times.

Thanks lads!

Scatmanjohn, I did slightly contemplate it, but after just looking at the thickness of the wall, I turned to the roof. You may have just brought my attention back to the wall again............!

It certainly is a lot better than going through the solid roof, as I wasn't looking forward to it, but I can cope with the wall.

The largest drill bit I can see in Screwfix is the 1000mm x 22mm one......... I was gonna get that for my new central heating system anyway!
