IKEA kitchen and XL dishwasher

That depends on the angle at which you look at the plinth panel.

Yes, that's true. How is it on the side of a tall cabinet where there is an end panel? At the front, the plinth on the base cabinets is recessed a bit, but how is it on the side of a tall or base cabinet with an end panel? Would you immediately see a 1cm gap there? Regards Section Chief

You'll see that then. Just take a 21 cm high baseboard and cut it to size accordingly.

Then you just take a 21 cm high plinth panel...

Thanks, I didn't know Ikea also has 21 cm plinth panels.
Best regards
