I was actually asking the question from a slightly different

Hi, I planned to get one where the actually motor/fan was situated in the
loft with just the ducting above the shower. I believe that these are safe
to use over showers.

I think I'll just replace the current wall one with a new model as I don't
have the guts to get onto the roof!!!
