Most fan isolator switches for bathrooms and WC are positioned outside
the room above the entrance doorway. As far as I can see you only need
to provide isolation for the fan the rest I would suggest is wired directly
into the lighting circuit you describe. I do not know how you intend to
create the cubicle but presume it will be a studded structure with a wall
and doorway at right angles to each other. If so you should be able to
wire in the isolator switch during its construction.

That is a good point, the cubicle will be a standard dry-lined
construction so, as you say, I can put the isolator switch high up and
out of the way somewhere there. Is there any good reason for the
isolator switch being outside the cubicle?

Not unless you have a bath or shower in your cubicle, which sounds
unlikely. But I would put it where no-one is likely to touch it with
wet hands. High up should do.



The light is integrated into the fan, though in principle I can't see
any reason for not wiring it such that it can be turned on even when
the fan is isolated.

I have a similar appliance. That is I suppose ok if the fan *can*
actually be serviced without risk of shock from the light circuit. Mine
couldn't be, as the light needs dismantling to get at the fan.



Another thought - would one 'service' the fan from the 'user' side or
would it be more reasonable to expect whoever services the fan to want
to access the back of it? That would affect where you'd want to put
the isolator switch. ... and anyway, who ever services a toilet
extract fan? :-)
