Maybe one should read the links before complaining:
where is there a complaint here?
Although one would really be justified.
What is the game with the dimensions, which merely represent a manufacturing tolerance indication?
Exactly the same can be read in this foreign IKEA house for the other cabinet types as well.
So apples are being compared to pears.
From this, it cannot be concluded that the new cabinet types are 3mm larger than, for example, the 600mm wide old cabinets.
I believe that the claim referring to the (exact) nominal dimension has been lost sight of at some point.
The new cabinets are also never wider than the nominal dimension.
So the "calculation" that the doors would no longer fit because they collide with the neighbor is irrelevant.
But that was the point of my inquiry,
which was unnecessarily interpreted as a complaint.
I had also asked if anyone has
experience with the problem.
Apparently not.
