Incorrect drillings in the Ikea kitchen tall cabinet with drawers.

hello community,

I had a cabinet specialist at Ikea redesign an oven tall cabinet (233) for me so that there is no door at the bottom but 3 pull-out drawers instead. Today during assembly, I realized that the pre-drilled holes do not match the spacing of the drawers... the lowest one is still correctly positioned, but the one above has a 1.5 cm gap, and if I move the rail further down, the fronts overlap. :(

What is the best way to proceed to drill new holes??? I’m a bit at a loss right now...

regards

Not at all.

Drive there and exchange it. With a 20-year warranty, I won’t drill anything.

But something else:

What fronts do you have, meaning which individual heights?
