Hmm we have an Ikea a few miles away; might have to stop and look.
The Ikea sink: 17 3/4" x 5 7/8" @ $46.98
The Dawn sink: 16 1/2" x 7 1/5" @ $119.00 (what its showing for my prime account)
I like the Ikea price but the Dawn sink is about 1.5" deeper. I guess the depth wouldn't be that important if you also replaced the faucet--ours doesn't have the pull out sprayer like Craig has in his pics.
