Beautiful 😍. I am installing a similar one and I saw Menards had the sink sitting on a shelf with a cutout for the drain. I planned on doing it like you did. If you had to do it again, would you do it with just 2x4's or a plywood shelf too underneath?
Yes, l followed Ruvati's instruction to be a bit lower than the cabinet but l was instructed by the person who measured the cabinet top for granite installation. He told me to have it level with the cabinet. But l gave it about 1/16" gap.
Not a bad sink at all. Ofcourse any other sink require detail cleaning you know. It has been more than 6mos and no complaint ( minimal cleaning require) to bring it back when its like new.
