Apologies if this is the wrong section but I'm working on the assumption it's generally sparks that would install extract fans...
I need a bathroom extract which will be installed by our electrician after I've core drilled the hole.
I've been offered a loan of a 117dia core drill to save hiring one, but want to make sure it's the right size as I assumed I'd need something closer to 100mm for a small bathroom extract.
Haven't chosen a specific fan yet but assuming extra low voltage wall fan with trickle and boost.
Can anyone confirm what the usual sizes are and what I line the hole with once it's made???
