I am not sure but FYI i put a similar sink in for a client that insisted and now she wishes she had gone with a standard rectangular sink the jut in makes it awkward for large pots and pans.

It's made by Elkay, called Mystic... model# MYSTIC3021BG the shelf is removable.

thanks Patricia and GN Builders. Yeah that's a good point Patricia ..

Actually that is a very large sink, you will not have any problems with large pots.

It measures 29 3/8" X 18 3/8 and that is the bowl dimensions and having a faucet offset, its perfect for handling large pots. It's way larger than any sinks 70/30 or 60/40.

Good luck
