Hole in tile too large for back box (SORTED NOW)

[lmhud]

Tiler has cut hole in the tile slightly too big for the drywall back box to house a fused spare for a macerator.
Any idea how to fix it.
Thanks

Get tiler to replace tile.

Slightly too wide. So the yellow locking tabs don’t catch the tiles.

Does the front surround of the back box go into the hole too, or is it just the locking tabs are not catching

Touches top and bottom.

So will the cover plate cover the hole, ie the fused spur plate.

Would one of these work?

No. Gap on either left or right side depending on where I put it

You can slide a bit of flat thin timber int he hole that is longer that top to bottom, add some adhesive to it so it sticks to the back of the plaster board above and below the hole. then fit the back box and do up against the now reduced hole.

Or you could just fix standard back box in the hole.

Show us a pic of the hole. You may be better off with a metal back box rather than a plastic "drywall" one.
Surely he has a spare tile.....?

This is now sorted. Bit of a small gap on right hand side but you can’t see it as it’s to close to the window wall.
Thanks for all the replies.
