hi john,
the easiest solution is fit an ordinary switch out side the bathroom
door. an ordinary switch is not suitable for bathrooms so out side the
door to comply with regs

Though regs creep is almost always in the direction of increasing
restrictions, bathrooms is one area where they've become more permissive
in certain ways. What Bob wrote used to be the simple and entire truth.
These days, "ordinary" plateswitches are permitted PROVIDED they're out
of reach of bath or shower - Zone III or Outside-The-Zones, which if I
remember correctly means at least 600m from the nearest edge of any bath
or shower; and should be of a 'suitable' type for the prevailing
conditions (i.e. an ordinary plateswitch would be OK if it's not at all
likely to get splashed, but if there's a showerhead which might splash
about then an IPx5+ switch would be sensible).

That's from memory - google about for definition of the Bathroom Zones...
