There’s zero risk with even a socket in a bathroom, unless you are in the habit of going for a bath with a plugged in toaster.
The regs are to minimise risk as much as possible.
In my en-suite, I can be standing in the shower, screen door open, bathroom door open, and I can touch the switches in the bedroom with wet hands…. But I’m not going to!
When I visited New Zealand, they had an RCD socket in the bathroom. No special pin sizes, could have been used for anything.
There are erroneous regulations throughout the book… why are WCs and kitchen sinks free from special location regs? Why do bathroom zones sometimes stop short of the height of a bathroom?
We can all work to the letter of the law, but there’s no problem going that extra mile to make things even more safer…..
So for me, bathroom switches and shower isolators are on the wall, outside the bathroom completely. I try not to use pull cords simple because they break too easily
