    As title really – above shower head or opposite side of room (circulating air and all that).

    It’s not designed to circulate air. You want it to remove moisture laden air from the room as quickly as possible so it doesn’t condense on surfaces and create condensation. Therefore, above the shower (if that’s what’s mostly used) would be better.

    Sorry – I meant that the shower is near the door so if it’s open I assumed air would sweep around the room and the fan might be better elsewhere.

    I did assume above shower was best but was just checking though.

    As close to shower head as possible, but you need to keep the ducting pipe as short & direct as possible.

    Opening a window makes a big difference to their performance too, they draw much better with a decent flow of air coming in.

    Above the shower is best

    On the continent they have vents or slots cut at the very botton of the door to allow air in so the fan doesnt have to work as hard to remove the moisture. ( no venting fans essentially pulling a vacuum and doing very little

    Ill be doing this on my new doors. Experimenting on the old ones atm to find optimum size that my room needs

    Very nice – its only a cold draught if the rest of your house is cold.

    I have seen the vents in action – questioned some locals on it.

    What drew me to it is the fact that i could shave in the mirror no bother after a shower….

    So tried a shower in my house with the door ajar – again i could shave straight after without a misty mirror – same thing with the door shut . Mirror steamed.

    Try it for your self

    If running anything other than through an outside wall use the rectangular solid ducting – fits under floors and doesnt sag 🙂

    I aint talking about a huge vent btw – if you have ever be to a domestic house in norway or poland (places i noticed them anyway) they have these sculpted gaps between the floor and their doors – maybe a quarter to half an inch high along the bottom.

    4 air changes per minute!. That’s 240 air changes per hour. That would involve extracting 750l/s from a 2×2.5×2.7m2 bathroom. Most domestic bathroom fans are hard pushed to do 15l/s by the time you attach any ducting to it.

    Use a 30 l/s fan, and it is standard practice in the uk for bathroom doors to be ‘undercut’ by 10mm, I.e. 10mm gap under door, for this very reason!

    It’s best to get rid of moisture before it becomes condensation, not deal with it in the 15 mins after.

    Heated mirror – I know I’m in a decent hotel when there’s a heated mirror.

    Undercutting of doors is quite common. I draw the line above 15mm. Some M&E engineers have asked for 25mm and my response is short
