How about a push to operate time switch outside the door and a
motion sensor switch in the bathroom, wired in parallel? The girls
could push the switch before opening the door and, if they are still
inside after the timer runs out, the motion sensor should keep the
light on.


The difficulty with motion sensors (the phrase takes on a whow new
meaning in a loo!), is what happens whey you stop moving... Bit
disconcerting if you are sat on the loo at the lights go off.


I wouldn't use a motion sensor - I'd simply use a PIR detector which
detects the presence of a warm body.

How would this cope is someone was in the shower/bath?
