Hi

I'm thinking of having my kitchen updated. All the exposed walls are tiled
but I hate the colour and the design on them so I want to re-tile the walls.

Ive been told its best to tile on top of the old as they provide the perfect
surface. Ive also been told that old tiles must be removed first.

So now I'm confused.

I'd be grateful for your views on which is best and why.

Thanks

Rob
