I have a 27 inch base cabinet. So I got a 25x19 single bowl deep stainless sink. Not a D. I didn't want my faucet off to the side, so I tried to find the biggest sink to fit in my cab. I am very happy with it, I can fit sheetpans and everything in there.
Here is a link to a previous thread about 27 inch cabinets. My sink is linked in there.
