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

Oh, the local woodworm will surely manage it properly so that it still remains IKEA-priced.

We will now solve the problem with a 30 and 20 cm base cabinet. these will be placed next to each other and the side walls cut out enough to accommodate the water connections and sink depth. so I am left with 3 mm of the entire length. I will come up with something for that as well.

How do you do it with the cabinet and the front? They aren't available in 30cm at Ikea, are they?

but recently there are 30 cm cabinets again.

Ha! Brilliant! Passed me by, but comes at exactly the right time :)

I have been planning for ages. Due to the long planning and the product expansion of Ikea, some of my planning has already become easier. By the time I am done, the 50cm cabinets will probably be available again. They would also help me a lot.
