I've been toying with the idea of replacing the lightswitch in the
bathroom with a PIR sensor so I don't have to remember to turn the
lights off.

Apart from sensors designed for burglar alarms the only one I've seen
that comes close to what I had in mind is at Maplin. Trouble is, the
blurb says it's not suitable for bathrooms, or for switching
fluorescent lights (not entirely sure why)

Has anyone got any idea where I might find something along those lines?

Why not use a push button that slowly springs back giving you 'x' amount of 
time?
either way, it would be a pain if you are in the bath or reading while doing 
something else
and the light kept going off. Would'nt it ?

Sitting on the loo having to rock around to keep the light on, doesn't sound
to comfortable to me.  :-)

Try a timed switch that give you anything from 1 minute to, sometimes, over
360 minutes.  All you do is press it in and it times out itself.

A low voltage PIR that works with an alarm system will work as long as it
has the option of having Normally Open contacts instead the most common
Normally Closed type.  You can make a transformer power supply in a box
along with a relay switch that operates on low voltage but switches high
voltage.

Low voltage in a bathroom is allowed, and the relay acts like any other make
and break switch which can be used with fluorescent lights.

OK so you sort this problem out  and you don't have a problem with leaving 
the light on in the bathroom.
What about the other rooms ?

There are a number of these IR switches, and certainly some of them
work with fluorescent lamps. Look for one designed for outdoor use,
which also requires a connection to the neutral (and hence doesn't
power itself through the light). Other advantage is you can fit it high
up at the ceiling (possible instead of your pull-cord switch), and
they are somewhat more waterproof than the ones designed for indoor
use.

Try the Screwfix catalogue.They have separate power so will work with 
Flourescent lights.

You CANNOT used push buttons switched etc in the bathroom, they must be put 
outside the door!

Use a low wattage fluorescent bulb. If it gets left on it won't cost so 
much. The real answer to your problem is to remember to turn the light off.

If your that forgetful, I hope you don't use a chip pan in your kitchen !.

But then again - maybe you've fitted sprinklers !!!  :-)

drill a hole in the door & cover it with a decorative clear cover, maybe a
bicycle reflector!

Thank goodness they don't call them "motion detectors" ;-)
