Wet room waste

charliefunkuk · 25 Oct 2006

I am planing to install a shower cubicle without a tray in my bathroom, I would of course need to use a wetroom waste that will sit under the floor between the joists. My problem is that where the waste will exit the floor into the joists I have downlighters in the downstairs room quite close but not touching. Would this be allowed? Is there any precautions that could be taken? even if I install a shower tray it will still be above lights.

Comments / suggestions appreciated.

move the waste or the light.

i know its easy to say and hard to do, but better safe than sorry

what would be a safe distance though, and either way the waste will at some point travel past the downlighter as I have a lot of them along the whole run of the joist/waste route.

Every downlight is different with regards to distances away from materials and also depends if the bulb emits the heat downwards or up through the fitting. A safe distance would probably be 30-75mm but that is only rough advice, where possable MI should be read for the light.
Again a 20w GU3 (lowvoltage) lamp will give out less heat than a GU10 (230v lamp), so depends on bulb rating and type of lighting system installed.

the lamps are gu10 50w so will give out heat, they are the fire rated ones in there own enclosure. I expect the waste to run approx 3-4 inches from the lights. Moving the lights isnt an option as there is simply too many in the downstairs ceiling

If they are the fire rated lamps and not lamps with fire bags/hoods then the holes in the top of the casing need ventilation to allow the lamps to cool. 50 mm above should be quite adequate.
