Tiling under Electric Shower

[Scott]

Dont Silicon around the shower without checking the manufacturers instructions!

A lot of electric showers use the airspace behind the shower to keep it from over heating.

Good luck.

What ever you do dont just turn the power off at the pull cord/switch you MUST pull/isolate the fuse.

Electric showers are encased in a plastic box with no vents or areas for cooling whatsoever. Thats the whole point of the plastic casing.
They do need to be siliconed around to prevent water getting in.

For my two penneth, don't seal underneath, if water is getting in or it's leaking the water can get out instead of building up inside.

I didnt say there were vents, they require the airspace behind the unit to keep cool. Its an 8.5 KW heater, ie 3 times more than your average kettle and it needs to be kept cool.

I have fitted plenty of electric showers on my installations and all the ones i have fitted have stated not to be siliconed the unit to the wall. Hence why i said check the manufactureres instructions, Im not making this up for the good of my health you know

If your removing tiles and are going to retile, there should be enough room by unscrewing the box to slide out (old tiles) and in with new tiles.
Always isolate the power to unit first and seal around unit on completion to stop water getting in after.
Behind the box is usually a water feed and an electric feed wire only and when removal of the front casing you will be able to locate these and the screw fixing holes which you will need to refix on completion..
Check that the unit is working before you work around it and then there is no excuse for it not to work after.

sorry to disagree but you should never seal the shower unit to the tiles. if you do you trap the heat from the shower inside the unit.

i am a fully registered sparky with over 20 years in the trade and fit these all the time.

i have to admit that every spark i have ever worked with during a bathroom conversion have all said the same DO NOT Silicon around an electric shower unit...including the guy i worked with on monday and he has a company that solely fits electric showers.

I isolated the shower fuse and slid the shower out and removed the tiles although it has been a little difficult to remove the old adhesive and level the substrate underneath to prepare for tiling - i'll cross that when i get to it. Tanking is also goignto be a little tricky , any tips would be appreciated .

I'd also like to ask , wouldn't water get in eventually through the water pipe hole if you didn't seal the top of the unit?

Thanks for the help guys.

I usually fill that hole with Silicon anyway.

me too

That hole is fine to Silicon. The motor and electrics are postioned so that the water shouldnt be able to get onto it. Most have a little splash guard over the windings to keep them dry, although i have also seen people throw them away..:yikes:
