That shape is going to be an issue if you somewhere have kept all the specs on that sink you could at least then show it to a plumbing store to see what is available. If you have actually found a single sink in the same shape that is IMO the perfect answer. Not sure how more kids relates to a bigger sink but IMO that sink you found is the answer.

Take a look at this thread.

search for Joseph Corlett. He's our resident countertop person and has shared many of his sink changes on this list.

So you can get a bowl like this in SS or the manmade granite

I feel your pain with the double bowl sink! When we moved into our current house, we had a double bowl sink that I absolutely HATED (and to think I was excited about this feature when we looked at our house). We quickly replaced it with a GIANT single bowl. I love it. I can fit two large crock pots in my sink and still have room to spare. I'll never go back to a single bowl sink.

In regards to the shape of your current sink, there are single bowl sinks with similar shapes (my current single bowl is shaped like yours with it bumping out at the top on the left, unfortunately it is not undermount). It would be helpful to know the exact specs. I will echo Patricia Conwell Consuling's comment that going to a plumbing or kitchen supply store with your issue may be the best answer. Also, if you know who installed the granite, they may also be a good resource for some advice.

Your sink is probably well-glued to the granite, and the granite is supported by your cabinet. Removing the sink may be a problem. And another problem is cutting the granite to accept a different sink. Check with your granite fabricator to see if it is possible. That would be the person with the knowledge and experience.

This is so timely because I was just measuring my sink opening this morning. I also have a double bowl that I'd like to replace with a single (mine is rectangular so might be easier.) I have the Kohler model number for my existing sink so I was planning to ask Kohler for recommendations that would fit the same size opening. (But I still have to deal with the plumbing - 2 drains to 1 potentially.)

I love my 60-40... and i had 2 under 2 at the time... i have single big sink in my second home..i wish i did the 60-40.. oh well

I would replace with an apron front sink as discussed in the thread that Blubird linked above.

I think the only way you could go to a rectangle would be if you were willing to have the faucet at the corner -- there's just not space to move it straight back. I'd replace with the ones designed for that, or with a farmhouse sink that can mount a faucet too.

"Your sink is probably well-glued to the granite, and the granite is supported by your cabinet. Removing the sink may be a problem."

I had the sink, disposal, faucet, and soap dispenser above removed in less than a half hour. You drive a stiff scraper between the sink flange and the stone bottom, then twist a flat screwdriver between.

" And another problem is cutting the granite to accept a different sink. Check with your granite fabricator to see if it is possible. That would be the person with the knowledge and experience."

Most granite fabricators don't have the equipment or experience to cut, re-profile, and polish a new cutout on site dust free. That ^ took me 7 hours, plumbing included, and I'm really good at this. If you screw it up, you may replace the whole kitchen if you can't get the replacement island to match the rest of the tops. That means your fabricator has to send his best guy. That's usually too much risk for the production boys.

One of my guys mistook an undermount for an apron front job. Fortunately I pick the right forgiving customers. Coulda been catastrophic.

Trying to hunt down a single bowl to match a double bowl cutout is mostly an exercise in futility.

Surprisingly, a Blanco stainless steel will acceptably fit a Kohler cast iron cutout but even then, the front reveals are off just a tad even though the sides and rear are near perfect:

Joseph Corlett, do you remember what the information is for the above stainless steel undermounted sink with the deck for faucet & soap dispenser?? I'm looking for a 32" or 30" like that. I hate the faucet on top of the granite.

It should not be too hard to remove the sink if it has been there awhile. My sink was separating from the granite. (I have had the sink and counter top for 12 years). The fabricator indicated that is a common problem. I kept my same sink, and had to have it removed and glued back and braced. If you have to pay someone such as Joseph for 7 hours labor that sounds expensive. Is it really worth it?

Susan, I am replacing my countertops and want a stainless steel undermounted sink that has the stainless deck exposed for the faucet and soap dispenser. I can't seem to find what I'm looking for and Joseph has posted some in the past and was hoping he would see this question.

Susan:

I'll re-strap a fallen sink in just over an hour, plumbing included; my minimum charge is $500.00. You'll get a new cutout profiled and polished, the sink installed plumbing included, for 7 hours.

It isn't usually too hard to remove a sink unless the sink was epoxied in place instead of siliconed. When your installer drives a stiff scraper between the bottom of the stone and the sink flange and breaks your top, better hope he can fix it inconspicuously:

wcjo:

My second picture above is a Kohler 3821-1-NA which can be undermounted or dropped in. The fourth picture is an Elkay 13322 which is a drop-in sink that's undermounted. Unless you go custom, that's the only way you're getting a faucet deck which is an excellent idea. Better to dribble wet hands on stainless than on stone.

I wanted to do the exact same thing and I only got one quote which was for $900. I decided to put that money towards replacing my counter tops.

Thank you, I appreciate the reply. I really hate the drips on the stone!

One more question if you have time, would you say that it is possible to have a drop-in sink with the holes undermounted, could they cut the granite to keep the rear holes exposed??

Sorry, but I don't understand your question.

I have seen some sink styles listed as duel mount (drop in or undermount). I guess what I want is an undermount sink AND the sink's faucet holes not covered by the countertop because I really want that stainless faucet deck! Is that what you did with the Kohler sink? And thank you again for even trying to figure out what I'm trying to explain : )

" I guess what I want is an undermount sink AND the sink's faucet holes not covered by the countertop because I really want that stainless faucet deck! Is that what you did with the Kohler sink?"

Yes.

Thank you!

A Happy New Year to you and your loved ones.
