Deviations in kitchen measurements due to fine plastering of about 1.2 cm problematic?

Hello everyone,

I have ordered my first kitchen (L-shape + kitchen island). Since it is an old building, after measuring and kitchen planning, it turned out that the electrical wiring had to be redistributed. This has already been done; now the numerous electrical slots need to be filled and the walls replastered (the wallpaper will also be removed).

According to the painter, about 4-6mm will be applied to the wall.

My question now: are deviations of up to 6mm per wall problematic compared to the already completed measurement, or is a tolerance usually factored in based on experience? Since the longer side actually concerns 2 sides, the total deviation here can be up to 1.2 cm. On the shorter side, there will be a freestanding refrigerator, so 1 cm more or less is not a problem.

The countertop is natural stone.

Unfortunately, my kitchen fitter is on vacation until next week; the painter is supposed to start in the middle of this week.

Attached are also pictures of the planning.

Thank you very much in advance!

Let's put it this way. If you order a 5m kitchen for a 5m room and the room is then only 4.98m, you have a serious problem. But on the phone it looks like one side is going to be fitted with a 54mm panel for connection anyway. Reworking by the kitchen builder and there it was.

What does rework mean. This is a tall cabinet shadow strip that is cut to size by the installer anyway. It is then not 5.4 but 4.2 cm wide. If there are hinged doors on the tall cabinet, you have to check whether they collide with the wall.

That's what I mean. It was hard to see.

Thanks to both of you, that reassures me a lot!
The tall cabinet only has standard doors with angle hinges, so no hinged doors.

Only the windowsill probably has to be 6 mm longer.

Why does the windowsill have to be 6 mm longer? At most 6 mm deeper ... isn't the countertop planned in the window recess?
