Condensation In Bathroom With No Window - Best Extractor Solution?

Yes, i'll update shortly doing the work now - we've added an access hatch for the ACM 125T Vent axia.

Quick question though - when swapping to the solid 5" ducting, we've found a horizontal piece of timber spanning the joists and it wont allow enough space to get the 5" ducting through.

As an alternative - is the flat/rectangle ducting any good? If so what size is equivalent in performance to 5" round? As that may be our only option short of notching out this piece of wood.... but it means ceiling down if so.

You can cut / notch this timber it’s only there for cross support and tbh 2” is fine

204 x 60 is 5” equivalent
220 x 90 is 6” equivalent.

thanks - don't have any where near the width for that. So notching out it is!

cheers

Update on this one - Couldn't get the ACM150T in there as there wasn't enough height clearance in the ceiling cavity.

But the ACM125T went in there.... just.... now with 5" solid ducting It's blowing super hard and really not that loud.

No condensation on the walls even during a long shower now, and id say leaving the fan on for about 5 mins post using the bathroom, even the glass shower door was bone dry.

Overkill, perhaps.... but we got there in the end, thanks for all your help.

Couple of photos im putting up too before i close the chapter on this one haha.

Forgot to mention when we cut a hole up there and found the old flexible ducting, the installers had nailed an electrical cable to a joist to 'hold' the ducting in place, I presume before the ceiling went up....but the cable was completely throttling it. I guess that explains why the original Axial fan I had did F-all. Certainly wouldn't have helped anyway.

And the other photos, ACM125T neatly in place, solid ducted up and a neat little hatch I made for an access panel should it ever break down in future

thanks again all.

Not to dampen your enthusiasm for a job well done but until the winter arrives you won't know ho effective the solution is.

Bathrooms need a lot of heat AND ventilation ..................
