I read in an old DIY book that it is against building regulations to position a light switch within eight feet of a shower cubicle (or bath aswell, I suppose). Is this correct? The pulley switch is obviously safer, but is there a distance thing required, or is it that you shouldn't have normal wall switches in a bathroom?
As long as the light switch isn't in the same room you'll be o.k. Also, don't mount the switch on a wall backing onto the shower cubicle incase water gets into the partition.
As I remember it, and I'm sure it won't have changed, you are not allowed any wall mounted switches in a bathroom. Any switches (lights or power isolator for an electric shower) must either be pull cords or outside the bathroom. All so you can't get an electric shock with wet hands.
