45 cm sink with a rinse basin in a 40 cm cabinet?

new problem sink: Due to lack of space, I have to choose a 40cm base cabinet for the sink so that the 60cm dishwasher fits. This leaves 12cm free in the row. It is very difficult to find a sink for a 40cm base cabinet. Especially since I also want a small rinsing basin. From 45cm cabinet width that would be possible. My idea now would be, the side panel has to be cut out anyway because of the dishwasher water supply. If I place the 12cm gap between the sink cabinet and the dishwasher, and choose the rinsing basin not deeper than the countertop (4 cm), Then there should be enough space for the water drainage of the rinsing basin???? Is this now wishful thinking or possible? The option of a 60cm sink cabinet and 45cm dishwasher is not an option. I thank you in advance for your hopefully soon answers. Anita

I would like to apologize for the above typos. In the headline, [Resebcken] should of course have been [Restebecken]. [Wunschdenjen] should have been [Wunschdenken].

Oh, it's not due to typos that I unfortunately can't come up with a solution or assess your approach.

Buy a 50 cm base cabinet?!

There will be an Ikea kitchen, there are no 50cm cabinets.

Leave the 40er cabinet and wash it in the bathtub :D Sorry, I can't think of anything either
