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.

Yes I was wondering about that. More importantly lounging in the bath -
you wouldn't want to have to get and dance the mambo to get it back on.

Waving a hand works, although the switch in my bathroom is set to five
minutes and I have rarely had a problem with it not detecting some motion
during that time.
