ᐅ Installing a Toilet – Is a Wall-Mounted Frame Necessary?

Hello everyone,

I have a technical question that I couldn’t find an answer to on Google, or maybe I just didn’t search correctly...

Here is the situation: We are in the process of buying a house. Unfortunately, we will only get the keys in two weeks, and we will then plan everything with a professional company, but I would like to get some information beforehand.

The house unfortunately has only two very small bathrooms. Currently, the old toilets with visible flush tanks are installed. We would like to change that. I thought a wall-hung frame system, which is then clad and has a shelf on top once finished, was the only option.

However, I have heard that someone installed the toilet system inside the wall behind the toilet. At the moment, I doubt that this works or is allowed, but I am not an expert. Of course, the wall has to be thick enough so that the installation components don’t come through to the other side.
Is such an installation really acceptable? Can the toilet system components simply be fitted inside the wall? From the pictures of wall-hung frame systems, these are large units, and I cannot imagine that cutting such big holes in the wall is permitted.

Are there any alternatives to the wall-hung frame system besides the old, unattractive flush tanks?

Best regards

Basically, this is almost space-neutral, since the exposed cistern is not exactly tiny.

Before the energy saving regulations came into effect, it might have been possible to build the exterior wall behind the toilet as a parapet with a thickness of 11.5 cm (4.5 inches), similar to radiator recesses. But nowadays, I don’t think that’s feasible. You would almost need antifreeze in the cistern.
