Don't forget the wireless BT/visonic door sensors could also be used to
help
with this, with external reed switch maybe on the shower door? They also
have a spare input, so you could even fit a small discrete reed switch on
the toilet seat, flush handle, etc :)

Savastore have them for around a tenner at the moment:

I would assume because they are battery powered & wireless, there is no
'P'
issue :)
