Kohler Cape Dory®
33" x 22" x 9-5/8" under-mount single-bowl kitchen sink with 5 oversize faucet holes

Kohler came out with Riverby®
27" x 22" x 9-5/8" under-mount single-bowl kitchen sink with accessories and 5 oversized faucet holes which will fit in a 30" base . I was told that they are being made to order. Riverby

Thanks for the recommendations. It looks like to use the space most efficiently we have to put in a 39" cabinet. Unfortunately, it's a small kitchen, so countertop space is precious and we still need a small sink. We are either going to do the larger Rohl or the Riverby. I'm not crazy about the lines on the Riverby, so I'm still looking for alternatives! Thanks again

We ordered one of these. It is not installed yet, but it looks beautiful:

I have the Kohler Cape Dory and I love the single sink.

I have the Riverby and I'm very pleased with it. I don't have a lot of counter space either, but the sink is so functional that I don't mind the extra space it occupies. I use the colander/cutting board accessory all the time, but I don't use the rack accessory thing (not the bottom grid- which I have in the sink constantly). I have it in white and a family member has it in sea salt which is very pretty. HTH!
