Alternative to tiles in the guest bathroom

Good morning,

in our future house there is a tiny guest WC. There is only room for a toilet and a small washbasin. Currently, all walls here are tiled halfway up. We would like to tile only the wall behind the toilet and the washbasin up to the height of the pre-wall element and possibly also the wall next to the toilet, or cover it with another suitable material.

We were on vacation in spring, and there the entire bathroom including the shower was lined with huge panels. These panels looked quite thin; unfortunately, we have no idea what they were and didn’t look into it further.

Would it be cheaper/better to cover the entire pre-wall with such a panel? The wall is about 1.40 m long. Height like the pre-wall, I’m not quite sure about that. Maybe 1.20 m? I still have to discuss with the sanitary engineer how high is usual here. What I would like about such a panel is that there are no joints.

Do you know these panels and can tell me what they are called? Or are tiles still the "only right" option?

Thank you very much in advance.

There is no "one right way"... you can also simply have the wall painted in a desired color with a latex paint. It is also wipeable.

Plates.... what kind of material might that be?

Platten.... welches Material mag das denn sein?

I have no idea! They were very thin plates about 2m high and at least 1m wide. I don't think they were tiles but I don't know...

How did they feel?

Stone, so rather tiles.
Warm, rather linoleum

Without any specifications, there can be a list of all materials here, which doesn't really help you.
