Cracks in the bathroom wall, where do they come from, is it due to ventilation?

hi,
i have a rather small bathroom. and there is no window either. recently, i noticed some small cracks on the wall next to the water heater. do you have any idea what that could be caused by? maybe because the bathroom cannot be ventilated well?
best regards,

Where are the cracks then? Tiles? Plaster? Concrete? Stone? So if it's in the plaster and it hasn't been plastered for very long, then something was simply done wrong. But in a bathroom, this can also be due to moisture if it is not ventilated well.

Hi!

I also think these are cracks caused by the settling of the house. I hardly believe that something like this can be caused by moisture. Extreme cold and ice formation must also be involved.

How can you come up with such nonsense about the "sinking of the house" just because a few hairline cracks have appeared around the water heater. Sometimes silence really is golden! *****Check whether the mounting of the boiler is anchored deep enough and secure enough. The source of the problem must also be right around the boiler. :rolleyes::D
