We have a average small size bathroom, about the size of a standard box room. It has a window, that we always open when in the bath and shower, and leave open for about 15mins after getting out.
The problem is the ceiling above the shower keeps getting damp patches on it, this is beacuse even though the window is open if its windy outside, as normally is, the steam blows back in and causes this problem.
I was think of putting a small say 4" vent in the ceiling about the shower, something like (http://i01.i.aliimg.com/photo/v0/375596141/ABS_round_ceiling_air_vent.jpg) now is there any building regs etc that say this must be vented to outside by a pipe etc, or can i vent the slight amount of excess steam into the loft ? The loft is boads so i was going to cut the hole in the board and pop say 10" of 100mm pipe so it vented out into the loft.
Any ideas?
Thanks
