59cm wide GSP front?

Perfect for me would be if the dishwasher is flush at the bottom with the carcasses. Therefore, the Vario hinge for XXL or the Ikea sliding hinges would certainly have made sense on their own.

Or put together something like that - of course neat and maybe colorful or white.

I hope you have sealed the gap to the cover plate above. Otherwise, there is a risk that the moisture from the dishwasher will soften the countertop and the base units and dissolve them into their components.

But the bottom edge of the dishwasher front does not align with those of the neighboring cabinets. The main thing is that you like it that way.
