The problem with a corner sink is that to get a larger sink into that small of a base, it has to go further back in the cabinet, or the sides have to be scooped. Further back hurts your back. Scooping the sides voids the warranty and compromises the support for your stone counter in an already almost undersupported cabinet. If you want to maintain the standard 3" from the front counter edge, then a 25"-28" single bowl sink will be the upper size limit. You can fit a whole roast pan perfectly flat in a 25" sink, but with a DW, you won't really need to worry about doing that too often. If you push the sink front back to closer to 6" in front of the sink (A complete no-go as far as I'm concerned.) then you can probably cram in a 33".

Thank you LWO. The corner sink was not my first choice but like e/t else in life, this process has been a series of compromises. DH actually does help with the cleanup A LOT and he was more than happy with the corner sink although he was a bit embarrased in the store when I made him go through the motions of cleanup at a corner sink display so now he doesn't go with me anymore!

That can have some advantages :)

Mydreamhome, that's a fantastic visualization! Really great! But, I can't tell if you took into account the thickness of the cabinet sides? A cabinet's interior space is from 1" to 1 1/2" smaller than it's external dimensions, depending on construction method, with the 3/4" sides of frameless cabinets being the most robust side wall construction. It looks like the walls have zero dimension? If you did take that into account, would you mind if I linked to your diagrams for any future postings on the subject? If you don't want to keep the data on your server forever, I would copy them to mine and give you credit.

The other comment that I want to make is that if you choose a sink that is almost too big for your base, then it has to be attached to the stone before it is installed, because there isn't room to do the attachment after the install. That makes having a great fabricator critical. And it also makes the sink non removable. That might not be a big deal, but then again, it might. I have had kitchens where the sink had to be replaced. A silgranite where the corner crack wasn't immediately noticed has happened a couple of times. Then there was the lady who was throwing a party for friends and family to see the new kitchen and a bit too much alcohol was involved. The husband was "cleaning his gun" and well, it discharged and shot a hole in the sink, luckily missing the Volga Blue granite. We were able to replace the sink because it was a 33" single in a 36" standard sink base. If we had tried to cram a 33" sink in a 33" base, the whole granite top would have had to be pulled just to change out the sink.

I'm not answering your original question -- others have done that -- but making sure you consider something else.

I apologize if you already thought of this, but I remember it from when we were considering a corner sink and it's important. Consider NOT butting your DW right up to the corner sink cabinet or you could have some clearance problems. Do a search on corner sinks here and you'll see this mentioned. Seems to help if you insert at least a smallish base cabinet in between.

krabbypatty, thanks for thoughtful comment. Yes, I did consider it and that is why I ended up with an 18 in dw, not the 24, so I could put a 15 cab between the sink and dw rather than a 9 or 12 in cab.

Mydreamhome, you have proved again that a picture is worth a thousand words and I cannot tell you how helpful this is. Thank you for taking the time to respond. Have you seen LWO's comment? Does the side of the cab come into consideration with these sink considerations?

LWO, did that really happen? What did he think, you use dish soap like the lady who use hand soap to wash a chicken on tv? I always wondered what does one do if a sink goes bad. Does plywood go down on top of the base cabs before the stone as a foundation of sorts or does the stone lay right on top of the base cabs? I definitely want an undermount sink but am curious about the actual installation. I would have thought that the sink rested on the plywood, then the counter on top but you need to caulk, don't you? Thank goodness my plumber is thin and does not suffer from claustrophobia.

Live Wire--good catch. I was in a hurry when I did the design and forgot to include the side walls--probably because I popped the granite visual contrast in earlier than usual. I can correct it and send it to you if you like. Here's a question--could Catlover do the 30' sink if they used one of these 'gravity sinks' as then you would only have to worry about the bowl of the sink fitting in the cabinet? They use what I would call a low edge profile stainless sink, then they basically grind (miter?) down the granite around the sink opening just enough so the lip of the sink is flush with the countertop. The overlap of the lip of the sink is about 1/2" and this is where the lip of the sink sits. Then they just drop it in, brace from below & caulk around edges. Here's a pic:

Catlover-Taking into consideration that I forgot the sidewall dimensions, you are more than likely looking at that 30" sink being pushed back another 2" or so to make it fit (which puts the edge of your sink 6" from the granite edge). The best advice I can give you is to see if your granite fabricator or your cabinet guy have a 30" rectangle sink that you could slide into a corner cabinet base to see if it will work. As LWO points out, you can scoop the sides of the cabinet to make it work, but check with your KD on whether it will void the warranty--get it in writing if he says your warranty is still valid even with the scoops (scooping the sides is how we got our 37" double bowl sink into our 36" sink base). Otherwise, I would recommend going with the D-Sink.

Well, I don't know why the link title didn't show completely--the link above takes you to a Kraus sink that may work as a gravity sink.

I'm still confused. So does a 30 inch sink fit or does it go back too far? The KD told me yesterday that 28 would be the biggest. That's a big disappointment. I wanted a rectangular sink but she said she would try to find me a large D, the D's look so small. If that's the case, I feel like I should scrap the 39 asf (I wanted the 42 asf initially) and just go with the 36 corner cab and just suck up the smaller sink and frontage and make my DH do all the cleaning but this is a stupid thought as one uses the sink in every transaction that goes on in the kitchen and I still will have only the 18 in DW (not the 24). This would mean that the cab to left goes from a 27 inch 1db to a 30 inch 1db (which is a good thing since the stove is to the left of this cab) and the cab to the right of the sink will go from a 15 in 4db to an 18 in 4db which is what I wanted originally. OMG, I might actually get something that I set out for? I just can't contain myself.

I'm not sure if this is relevant or not but you didn't say if your planned sink is a double or a single but I will chime in about my situation. My single sink is huge and I am so happy with it and I also have more counter space so I'm not one bit sorry. We had a huge double sink with no space on the sides.
I am posting pictures of the difference.
