Attach the toilet to the stone wall

Hello everyone,

in our bathroom, the backsplashes behind the toilet and behind the washbasin are tiled with stone wall effect tiles (the ones that look like stones stacked on top of each other).

Question: Is it a problem to attach the toilet / flush button to this stone wall? The surface is relatively uneven after all.
Does it look unprofessional? What does the installer say about it or does he have solutions?

Thank you very much for your help!

I think that the "holes" between the ceramic and the stone will remain solely your problem. Usually, the joint between them is filled with silicone. You can compensate for a few millimeters with it.

Thank you very much for your response!

With silicone, my question would be whether it looks "cheap" visually when you fill it in and it's not nicely straight. Or does that not stand out negatively?

And how is it with the [Betätigungsplatte]?

You are already giving yourself the answer in your initial question. That may be the reason why so few people have such a rough and irregular stone wall in the bathroom. Besides this problem, the dust issue also comes into play: where you wave the towels around, more dust is generated than elsewhere. That then stays on the rough wall.

Can't the fixture be installed flush-mounted?

How is the toilet supposed to ever hang straight? That will never work. Besides, I would fear that the ceramic might break if it is braced against such an uneven surface.
