After pricing up a customers bathroom refurb, it has prompted me to do
something about my own bathroom.
The fittings are all ok, but the walls and ceiling are very dated (6"
white tiles, only around the bath,with grout going grey,ceiling in white
emulsion that has started to peel in a couple of places etc).

The tiling and ceiling will be done in the usual way - buy whatever I
can afford, then put it up when I get time.
But before I start on that, I'd like to put in new lighting.

I have seen one bathroom where there is a PIR sensor inside the door,
which lights up around 6 ceiling mounted low voltage
spotlights/downlights.
I'd like to replicate this.

How many lights are required (12v 20w iirc) to illuminate a ~6 feet
square bathroom?



I was thinking 4, plus an extra combined fan/light over the bath.

I would have said 6 but it depends on how light you want the room to be
- e.g. like an operating theatre or synergistic with candle lit baths.

You can place the lights near to the walls and arranged such that the
wall intersects the cone of light from the dwn lighters. This will
give a parabola effect on the wall and as long as the wall is light in
colour there will be good light reflection into the room. However,
you must then finish the walls and tiling to a very high standard
because blemishes will appear in sharp relief.

You may want to have additional task lighting e.g. at a mirror for such
activities as shaving and applying your make up.


Are there any kits with the PIR included?

PIR sensors. Easy to fit? Reliable?
How do they work? say it is daytime, but you want the lights on, will
they turn on then?

Adjustable.
