Hello and thanks for your question. My interior designer selected it and thought it was Kohler, but Kohler states it's not theres but similar to one of theirs. You can see the discussion in the following link as someone else asked about the sink previously.

Thanks for answering me so quickly!

You're welcome - I try to address these asap - it doesn't always happen but I try! Fortunately there was some history with this one.
