Hi
I am renovation a kitchenette and need to remove the backsplash tiles or cut the plasterboard where they are and replace it. I am struggling to remove the tiles without damaging the plasterboard. I am also finding the section of plasterboard behind the tiles above the sink give off a musty damp smell as I am pulling off the tiles. Would it be better to cut out the piece of plasterboard where the tiles are sitting and replace it with something more waterproof, rather than trying to remove each tile?
I intend to install a backsplash once the new cupboards are in, although not necessarily a tiled backsplash.

The tiles currently have a plastic fake tile look adhesive stuck to them.

Just need advice on whether to forge on or just cut out the section of wall and replace it?
