It looks like this one from Delta. But, in my opinion, that handle looks like it's awfully close to the sink, like when you use it, your hand would be not be in an ergonomic position and you may hit your hand and knuckles on the sink, so you may want to double check measurements before you duplicate this design.

Perhaps the shorter height of this sink from Native Trails may alleviate my concern?

Sorry for the late response, this is the Elkay ECB19BWBA Aged Bronze 22.62x22.62 sink with a Delta 753LF-RB Vero Lab Faucet in Venetian Bronze.
