Light Switch in Wet Room

[kingeri]

As Guitarist said. Perfectly summed up.

Assuming that the room is fully RCD protected, then you will be safe.
Taking your example further, the drain becomes blocked, the water leaks under the door and as you walk out of the wet room in bare feet over the wet carpet, you switch on the hall light and....

Follow the regs and employ a little common sense on top. Only the person who sees the situation can really make the decision ultimately. That's why we are qualified professionals

Yes, I see the point. One could also apply it to the case with a "bath overflowing". I would always view a wet room as an extended shower area.

What "gets me" is the citing of distances from the edge of the shower tray and concluding that it's OK; as it's "far enough away". The point I was trying to make (maybe somewhat poorly ) is that the danger doesn't stop after a certain distance in an environment like this. The regs should always be considered as a minimum and you take into account the reason for a regulation existing when making decisions. In my view that's the "common sense on top" aspect in this situation.

What if you completed the works and 2weeks down the line they change it to a wet room without you knowing?

I don't see that the change from a shower room to a wet room makes any real difference at all.

you can get detectors that fit onto a normal 1g light switch - just replace the switch for one of these, i think MK even do an IP rated version

Hi -do they require neutral?

 

[Doomed]

not all of them do - the ones that don't are a bit bulkier as they have a rechargeable battery built into them.

You can get a 2 wire no neutral or 3 wire requires a neutral

 

[sythai]

Here you go, no neutral required and I'm sure they are rated at IP44, good bit of kit used these before with no problems :

WAPIR (PIR occupancy switches) - DANLERS Limited - Lighting Controls HVAC Controls

Just another option and presuming the wall is 100mm thickness or less, any chance you could drill through and mount a standard light switch on the opposite side outside the wet room ? Then blank off the existing point, either with a 'nice' blank plate or get them to bring the tiler back to tile over properly.

All the best,

Sy

Then my conscience would be clear and I could swear in court that at the time I installed and tested it was compliant with the regs.

I don't see that the change from a shower room to a wet room makes any real difference at all.

Would you have used a plate switch in the first place though? If a pull cord switch had been used then OK IMHO.

 

[topquark]

I've just had a refresh on the regs for this. The definition of zones 0 & 1 horizontal reach for "showers without a basin" (which is effectively what this is) is extended to 1.2M from the centre point of the fixed water outlet on the wall or ceiling. Not sure what happens if it's a flexible head.

So I capitulate that this would be within the regs, I still think it's poor though; as the basin extends well beyond the 1.2M IMHO.

 

[topquark]

Reg 701.32.3 Describes zone 1 as 1.2m from water outlet if shower does not include a basin, this would include a wet room I believe

There is no zone 2 in this case

Appologies Andy, I completely missed your post last night :6:

Wet rooms are common practice, and far more normal to see, than the standard British bath/shower room in Europe and indeed overseas as a whole. You won't find many of those with pull cords or occupation detectors, ...nope they tend to have the switch in the normal position, and these rooms can be a lot smaller than the room mentioned above.

Come on, ...6m away from the shower head, and around a corner, forget all the what if's it's Fine!!! lol!!

 

[topquark]

If I was designing it from scratch as a wet room I wouldn't design it with a plate switch within arms reach of the wet area, that's for sure

I'd hardly call 6m within arms reach!!
