ᐅ Apply plaster directly over wall tiles or remove them completely?

Hello, I have bought a house.
There is a bathroom with a shower, fully tiled from floor to ceiling.
I am wondering if it makes sense to remove all the tiles, grind off the tile adhesive, re-plaster, and then apply wallpaper?

Or could you, for example, plaster directly over the existing tiles using something like Ardex R1 and then wallpaper over that? Does anyone have any experience with this?

I would appreciate any feedback.

Best regards, bloblu

Both options work, but I would always recommend removing the tiles.

If the tiles are smooth, straight, firmly attached, and you don’t necessarily need access behind the wall, I would leave them in place. Removing them is really a terrible job. And if there are professional options to avoid that—no matter how, whether tile on tile, plaster over tile, drywall in front, and so on—then so be it.

Okay, thanks. I think I will plaster it directly. Can anyone recommend a good manufacturer, or is Ardex already reliable?

I don’t understand the fear of tile removal here.
With a proper hammer and a flat chisel, a tiled backsplash in the kitchen can be removed in an hour. I have knocked down all kinds of tiles, stoneware, or whatever in several houses, and I find stripping wallpaper much more annoying.

Progress was always quick, especially on walls, where the tiles come off like nothing.

The most difficult were those thick stoneware tiles in the entrance area of a house, which were supposed to be very expensive. They were installed with a thick-bed mortar, but even there, a few square meters were done within an hour.

It's not about chipping off the tiles, that goes quickly. But sanding down the tile adhesive and replastering the wall smoothly xd
