Had a look around on t'internet, seems to be no real reason to
have a shower cord in the bathroom. Why does it need to be
switched off any more than any other appliance? Apart from
maintainence once a decade, in which case you pull the fuse in
the fusebox.

Doesn't have to be a pullcord, can be a dolly switch outside the
bathroom.
I don't trust pullcord switches, even if they have a mechanical
tell-tail, so I would always isolate upstream as well.

Every appliance needs an isolator, and an isolator must isolate
all live conductors - that is both line and neutral.

On a TN system there is no requirement to isolate the neutral and a
single pole MCB is allowed to be the isolator.


I didn't know that, and even if I did I wouldn't have been able to
convince the bathroom fitters (pre Part P)

They fitted the pullcord isolator three inches away from the existing
light pullcord, the obvious place for it was in the corner behind the
door when it is open. I got them to move it but it needed a JB to
extend the cable which I would rather not have I the loft.

The other thing they insisted upon was a unswitched FCU for the
mirror light/shaver socket, even though it was fed from a 6A MCB.
They kindly left the 13A fuse in it as supplied.


So much easier to fit things yourself, the way YOU want them. Why
are you not doing so, considering you're in a DIY group?
