My sink base is a little larger at 27 1/4. I got a Kraus 16 gauge and love it. It came with the sink grid, purchased mine on Amazon. The inside dimensions are 21 x 16 outside I think is 23x18 with .75 radius corners so very straight looking but not so sharp corners so it's easy to clean. It's 10 inches deep, with the granite it makes it 11 1/4 inch deep without grid.

Your welcome remodella. I just looked it up and it's about 100 dollars cheaper now than when I purchased it. Kraus Sink

We recently remodeled our kitchen and put in a farmhouse sink - really love it - so functional. They have some stainless styles that look pretty modern to me.

Is this for a prep sink or is this your only sink? The Kraus that Jancy posted won't fit in your 24" cabinet. We also have a Kraus sink with your parameters and love it. But it's quite a bit larger. We bought ours from faucetdirect.com and couldn't be happier with their customer service. Maybe dig around their site and see if they have one that'll fit in your 24" cab.
