LED bathroom mirror wiring

[ccarr32051]

Hi
I am in the process of doing up the bathroom and the wife would like one of these LED mirrors that are heated for demisting. Of the ones I have seen it appears that it will turn on with a button on the mirror rather than when switching on the lights. It will roughly go in the same area as in the pic below. My question is can I take a feed from the back of the shaver socket andbehind the plasterboard and out to a flex outlet cover and back box. The shaver wire is 1.5mm Twin and earth and is on an RCD. Or do I take a feed from the light switch outside the bathroom and run to a fused spur outside the bathroom and run a cable from the spur to where the mirror is going? P.s. the mirror is the old non LED mirror in the pic.

Thanks

My question is can I

Yes, likely you can, but rather expensive, bathrooms are a special location, here in Wales £100 plus vat, to do it through the LABC, and likely it will cost less to get a scheme member electrician to do the work.

Likely he will take the supply from the shaver socket supply, and also likely not neutral at the light switch, so would need to come from lamp if you can't use shaver socket supply.

Since you ask "can I" I assume you mean and comply with regulations.

Mine, and others I’ve seen, have a sensor on the bottom edge that you wave your hand under.

Well, not necessarily. Usually the sensor turns on the lights and there's a separate rocker switch for the heater element. Mine is like that. I guess that i don't count as "others" then?

But I dont like that arrangement, once the demister is turned on, nobody remembers to turn it off, so you are paying for the heater to run 24/7.

I have run L, N and switched L to the mirror. Use the perm L for the lights (sensor turns them on) and the switched live to turn on and off the demister. Needs a bit of simple wiring changes.

I do not shower in the bathroom, in fact rarely have a bath, so the mirror in the bathroom does not need a heater, the lighting in the shower room and limited space means rarely use the mirror in there, and it does not seem to mist over anyway.

What I have found, a shower needs a seal either top or bottom, so you don't get the chimney effect putting moisture into the room, or no cubical at all, as with a wet room.

Some day I will have a bath, got two in the house, but always shower, bath has an e-bike in it at the moment.

However, I think a pneumatic, timed push switch would likely work well? But when I get a job done, I ask the person doing the work, seems the right thing to do.

Wouldn't that be "may", rather than "can"?

I am wary when anyone asks can I. As they may be asking if permitted, I would assume they would know if they have the ability.

Fair point.

Thanks for the info. Yes I have done the odd move a socket or put in daisy chain sunken lights situation in the kitchen & bathroom and feel confident to tackle this. I was just wondering has anyone else done it that way or is there a better way?
