The level you measured in your current apartment and now take as a guideline for yourself!
I did not take my apartment as a guideline, but tried it out because we find exactly the same situation there. And obviously, the sentence was meant differently than I understood it. The word level is simply ambiguous. Then I am, of course, sorry about that. But maybe you should also consider your post from my position.
I can of course understand that when the draft receives incomprehensible criticism, one may react somewhat impatiently
As I wrote at the beginning, I understood your sentence as personal criticism and naturally one reacts impatiently to that because it has no place here. Furthermore, I never said that the criticism is not understandable, but that I cannot make use of it regarding possible better options. The bathroom would work one way or another for us, but one wants to explore all other possibilities as well.
I had planned to design the bathroom this evening, but now I am saving myself that.
Unfortunately, I could not resist responding after all... but maybe we can steer the discussion in the right direction after all.
