I measured the space from front to back under the sink and it's 24". According to Yahoo! Answers that is standard depth for a base cabinet. http://answers.yahoo.com/question/index?qid=20061016195518AAVAB32 I will lose one drawer to the right of my current bar sink to get the length that I want (36" - 42") The most fitting one so far seemed to be the Houser Novus, as the dual ledge / sliding system would be just perfect for certain types of prep I do often. However when I looked at the spec PDF, even though it said the sink was 18" wide, the cutting board that fit on top of it was only 15 3/4". I called 3 custom stainless places, and they all said that I would be shocked at how expensive a custom stainless sink is. If I have to go the custom route, maybe granite would be the way to go. Here is the concept of what I'm looking for, on steroids. It was featured on HGTV a couple months ago. I'm surprised scaled down versions of this are not common in small kitchens in order to turn part of the sink into a prep space. Maybe the concept doesn't really work well in practice. http://www.degiulio.org/work_signature_collection04.html Here is a link that might be useful: Mick de Giulio kitchen design

Standard apron front sinks are not terribly retrofittable into a standard sink base. Not without completely rebuilding the base to accept the taller apron, and then using a curtain below to replace then too tall doors of a standard sink base. Then there is the cutting and polishing of the granite on site. That is 3 hours of work by itself, minimum. Start at $1200 labor. End at around $2200. That is for a multi talented individual with extremely strong cross the board skills. One whom is exceedingly difficult to find. If you have to call, in a cabinet installer and granite fabricator both, expect to double the price. This ain't a hill you want to die on. Save hour money for a more extensive renovation down the road.

"to get a high quality it's 2-3x price of granite sink" Nope. Many on this forum love their Kraus stainless steel sinks. They are 16 gauge, which is thicker than the 18-gauge you see in many brands. You can find them on expressdecor or overstock. Also be aware that just because there is the name "Blanco", "Franke", or "Kohler" on the stainless steel sink doesn't mean it was made in Germany, Switzerland or the U.S. These companies sell many sinks made in China. I don't think that a Chinese sink is a bad thing. Just like in the U.S., there are some made better and some not. What I don't like is paying multiples just to have the name Blanco, Franke, or Kohler, thinking you are getting a German, Swiss, or U.S. made sink. These companies do still make some of their sinks in those countries, but you have to call the company's customer service number with the model number you are interested in, and ask them about it. Or the box will also say. But you want a granite composite sink. That seems to be your first priority. Something has to give. Blanco makes the best granite composite sinks, and holds multiple patents on their Silgranit material. If it were me, I would compromise on the 70-30 configuration, and get the BlancoDiamond Super Single Silgranit sink with the corner drain. Once you have a corner drain, you never go back.

the person that gave you the granite, what sink did they have in it? also keep in mind that if you find a bigger sink you like, you could have someone come out and cut the granite to fit it. it shouldn't cost that much to do. they can do it on site for you. do you have a type of vanity that is going to work w/that rounded bump-out part? If not, it may be easier to scratch this and look for the pre-fab bathroom vanity tops/sinks included. they're only a few hundred at most. maybe cheaper.
