Hi all,
It just popped into my head about bathroom pull cord switches, do they ever have flush mounting boxes, every one I have seen has been surface mounted, and also, why are shower pull cords cut shorter, which I see in most places?
 
Dry line box in ceiling

Thanks, is it like this one: Appleby Circular Dry Liner Box 35mm - https://www.screwflix..com/p/appleby-circular-dry-liner-box-35mm/90517?tc=AT1&ds_rl=1249481&ds_rl=1245250&gclid=EAIaIQobChMI1az04p_o1wIVZpPtCh0kHQMcEAQYASABEgJemfD_BwE&gclsrc=aw.ds&dclid=CLza6Oef6NcCFYmxUQodR08B3Q

To stop people mistaking the shower pull cord for the light switch?? I wouldn't use a dry lining box for the shower pull cord, far to flimsy for my liking!
 
Or you could use a square one for a square switch

But as others have pointed out, its not a brilliant idea - especially if you do it to a shower isolator.
 
As David says - and if I remember my training - all pull switches need to be mounted on a joist/noggin. If you use a dry line box, a medium pull on even on a light switch could rip it out of the ceiling, and shower switches need a decent yank to operate them.

The only way would be to engineer a wood support/noggin and fit a metal backbox up in the loft so the switch sits flush in the ceiling. But that's an hours worth of carpentry...
 
I have actually seen this happen, a flush mounted shower pull cord, hadn't actually ripped out of the ceiling but it was almost at that point, very loose and wobbly. Ceiling was a mess, not the easiest of things to sort out. Dry lining boxes are not a good idea for pull switches!
 
I also don't have an outside loo or have a bath once a month in a tin bath in front of a coal fire in the living room.......... :D:D:D:D
Come to that neither do I. But, but I do have a pull switch in my bathroom, 2 in fact 1 for the light and 1 for the shower
 
And a pull chain for the wall mounted ceiling height water cistern.......

Electric showers, jeeeez these Northerners are stuck back in the 70's

:p:p:D:D:D
 
A properly installed good quality dry lining box on a 12.5mm Plasterboard Ceiling is fine in my opinion. The cord would be snapped long before any damage could be done to the ceiling.
