Are click vinyl floors suitable for bathrooms?

In the bathroom, I would always recommend full vinyl flooring. On the one hand, the installation height is not too high, and on the other hand, full vinyl is moisture-resistant and can also be installed using the click system. However, it has the disadvantage that the subfloor must be absolutely even, because even the smallest irregularities become visible. Vinyl on a carrier board such as MDF or HDF is not recommended in the bathroom.

So, a new screed will be installed in the bathroom and it should be correspondingly level. Then the glued option would be the best? The critical point is still the kitchen. I almost have to lay the same floor here as in the living and dining room because it is one large room. Accordingly, a carrier board made of MDF or HDF is also unfavorable here? I can only lay it floating here because the floor condition is simply too uneven for gluing and can only be compensated with very great effort. In addition, the floor must be no more than 5mm thick because otherwise I probably won't be able to open and close the doors anymore... How does it actually look with a vapor barrier towards the floor, with glued and click variants?

Even with the click version, the floor must not have too many unevenness (max. 2-3mm), as there is a risk that the floor or the joints may come apart.
In the case of a privately owned home, in my opinion, gluing is always preferable.
With the click version with vapor barrier and impact sound insulation
With gluing without vapor barrier and impact sound insulation.
My recommendation would be to level and glue the floor everywhere (which will be necessary anyway).

Hello, I have a little problem here... On the 55m² that I have to lay, there is partly old flooring on it (PVC) that was glued down so massively that I see no chance of getting it out without really heavy equipment. I see hardly any option to do anything here except for a floating version. Unless I take out the screed, but to be honest, I wanted to avoid that.
