What fixings to use? Raw plugs?

[robbieee]

Putting an electric shower up and i drilled a hole using an 8mm drill bit. My walls are ceramic 8mm tiles onto plasterboard.

When i put the raw plug in it just spins round then drops down the back of the plasterboard!! What should i be using?

What size are the plugs? Sounds like the hole is too big.

Sounds like a job for the blues

What does that mean

The plug should be tight in the hole, not spinning, use a smaller bit and use plugs that have a lip on the edge to stop them pushing past the tile.

Blue rawl plugs

I cant, i have already drilled the 8mm hole

Blue rawl plugs

It was brown plugs i was using that i am pretty sure they said "8" on them. Will the blue plugs do the trick then?

Bri, I always tell sparks/plumbers to push the rawl plug past the tile & into the substrate

There is no give in a tile & if they over tighten the screw then it will crack the tile, especially ceramics.

I've seen a lot & sorted a lot of these problems round about shower screens etc..

Put a red plug into a blue plug, fill the hole with Silicon push in the plugs, fill with more Silicon & leave to set!!!

You get longer metal fixings with a setting tool, can't remember the name of them. They would do the trick but the hole would need to be bigger again..

Fischer do 8mm collared expandable plugs. Available at most diy stores.
Grey in colour, about 40mm. The collar will stop it going through the hole, when you tighten the screw it will expand and pull up behind th3 board. Just don't over righten the screw.
Infact righten by hand, don't be tempted to use a drill.
