I would go with as big a sink as you can fit. I have a 36" base cab and just put in a 33" single bowl stainless (although it's overmount). I can't tell you how much I love this sink, especially compared to the double bowl I had previously. I think mine is only 8" deep, though, which I prefer to a deeper one, since I'm slightly on the taller side. But I also use a countertop drying rack, which doesn't bother me at all. I know a lot of people like to hide their drying pans and a deeper sink will do that better, obviously.
Good luck on the remodel!

I have a 30" sink after years with a shallow double bowl. It seems cavernous to me. I think the depth is the most disconcerting. I know lots of people love the deepness, but it still feels kinda awkward.

hlove, I also use a countertop drying rack. Old ways die hard. There are simply things, e.g., frying pan, cat dishes, that I hand wash and need to set somewhere. Leaving them in the sink to dry is just in my way.

Why do you have to choose between two sinks from your contractor? You should be able to go out and purchase the sink you prefer. If you like the larger size (and I think everyone here will agree, larger the better),then it's a matter of depth comfort.
Shop around online and in brick and mortar stores to find what you really want and ask the contractor to install it. Good Luck!

>I think everyone here will agree, larger the better

Just to point out there are a couple of us contrarians who don't need a sink big enough to bathe a Golden Retriever or a preteen. Me, I'd go for the smaller one, but people's needs differ.

I'm one of those who think shopping for depth is more important than width. But now that I've been shopping, I don't see a lot of options if I want 16 gauge and also want the drain to be rear-off center (so I can more easily put trash beneath) and want it at a reasonable price. So I've just about given up and hope that I won't be working at my sink for long periods.

Question, does the 32 inch sink you have been offered have an option for a grid? I understand that can reduce the depth (though there are other problems with leaving a grid in place).

I assume you have a contract where the contractor has specified sink options. I understand. There are pros and cons to every contract (almost).

I don't think the look will be strange with a 28inch wide sink in a 36 inch cabinet. But may be some wasted undercounter space that could have been used for something else. But only you will notice this, I don't think it will spoil the "look" IMO but I'm a newbie like you so take my opinion with a "grain of salt".

Bigger. Better. But I agree to look around for yourself. Those two choices you've been given are but a limited drop in the SS sink bucket. What gauge SS is he offering you? Lower numbers are thicker metal. Are the corners zero radius? Do you want zero radius? It has it's pros and cons. I encourage you to do more research on your own.

My apologies, I should have said "many" would agree. If one has the space and the need with a large family and busy kitchen it's worth it.

And Gracey, my golden retreiver is 75lbs and would not fit in a 32" sink!

want the drain to be rear-off center (so I can more easily put trash beneath)

Okay, now I get it. My new sink has a drain square in the middle, which I don't mind and couldn't understand why people were adamant about not having it there. My plumbing falls right in the middle of my under-sink cab and is somewhat limiting in terms of trash and storage. However, out of all the things I'm second-guessing, this is not on the list.

Thank you for all of the feedback. Yes, the choices in sinks have to do with where they buy the sinks. I did go home at lunch and talked about a 30-inch sink and a couple other things, so we'll see what they come back with. I also measured (which I should have done last night, but I wasn't thinking).

Because the sink backs up to our eat-in area of the peninsula I don't think the 32-inch will look good. I think it will dominate the area and because it is also an inch wider I think it would push my faucet too far back into this area. It's just me and my husband (and a spoiled cat), so there aren't that many things that need washed.

The 32-inch did have a grid.

When I left they were ripping apart the wall to get the electrical done for my hood. I'll be happy when this is all over. This is my second kitchen renovation (different home). I thought this time would be easier. LOL

Remember too, that alot of times when they say it's a 28" or a 32" sink, that is the outside to outside dimension including the lip they use to fasten the sink to the underside of the granite, not the actual bowl dimensions which will typically be 1-2" smaller. So your 28" may really be 26" and the 32" may really be 30". With the smaller sink spans, the manufacturers sometimes reduce the width of the sink too so you will see a 28 x 16 vs. a 30 x 18. This is because many smaller sinks are used as prep sinks and not as the main sink.

So--long explanation to get to the advice of go for the larger sink. Also, take some dishes in with you to the showroom--a plate, serving bowl, roasting pan--and play house with them in the display sinks. That extra 1-2" in span & width lost with the smaller sink & gained with the larger sink may make a world of difference.

The 28-inches is the inner bowl measurement, so yes really a 30-inch undermount. And the 32-inch is also the inner bowl measurement. I have PDFs of the sink measurements.

Maybe seeing the area will help. Here's the rendering from the contractor. The three cabinets to the back of the sink area actually go across the back and make the eating area. We are adding six-inches of quartz overhang.

Maybe these pictures will help. I wish I had taken better ones when I was home at lunch.

I just bought this one for my kitchen:

I did a Best Offer too.
