Should the tiles be removed along with the concrete or not?

In our bathroom and kitchen, the tiles are laid right on top of the stones in the concrete. If I knock down just the tiles, what's left is a concrete surface with holes and open areas. If I remove the concrete as well, you can see the brickwork directly. I wouldn't want to tile it over because I want to redo everything once. 

Do I have to knock down all of the tile along with the concrete? (it's faster) or just the tile and make sure I don't smudge the concrete?

What is your direction? Do you plan to put cables or similar routes in there? Basically, you have three options:

1. leave the plaster and glue on the wall. Then smooth out the strip again. Prerequisite: the plaster is still load-bearing.

2. remove everything and re-plaster the wall or, if necessary, glue the drywall to it with adhesive. The advantage: a good smooth surface.

3. put the drywall in front of the bricks.

It all depends on what you want and what your goal is.

The tiles were placed in a mortar bed in your case. I would also remove this. The new tiles can then also be attached to the wall with mortar again, only the substrate must be free of loose parts, further processing is probably not necessary.

Or you plaster the wall after removing the mortar and then glue the tiles on it.

Are we talking about the walls or the floor? Concrete is a rough description. There is certainly plaster on the wall. If you remove the tiles now, you will have to re-level the surface. Or you can remove the plaster completely and glue drywall to the wall. This will provide a good base for the tiles.

We're talking about the walls. There is no plaster there. When I chip off the tiles, they end up right under the masonry.

We have glued the plasterboard to the wall in the bathroom. Soon there will also be tiled. The important thing is to really increase the heel trusses. And proper mortar on the boards.

With plaster I also meant the old glue/mortar.

Before gluing, primer must be applied to the masonry.

Well, for plasterboard the substrate must of course be well prepared, otherwise the tiles will fall off the wall again. The old tiles must be cleaned thoroughly with an alkaline cleaning agent and then primed with primer.

You should clarify in advance whether the tiles must/could be attached with plaster or glue. Furthermore, it should be considered that the panels should be sealed with sealing tape, sealing sleeve (pipe inlets...) and liquid foil in the shower/bath area.

Get advice on this.

When removing the tiles and mortar, be careful not to use too much force in the direction of the stones. Because otherwise the stones could loosen. Means work with the hammer drill parallel to the wall. And not at 90 degrees to the stones.

In your place in the bathroom – if the finished space is later sufficient to accommodate all objects, I would also work with green GK. Nevertheless, I would knock off all remnants of the former Speis; this is usually very easy and you keep – with double planking – almost the existing space.

In the kitchen, I would remove completely, create a homogeneous surface with matching plaster and then re-tile. Especially there, it often comes down to centimeters, which you "might" miss in a later kitchen planning.
