Thank you so much for inquiring about our project! Unfortunately we only keep records for 5 years at a time, but we do know that this is a Kohler faucet, for more information, please do not hesitate to contact me at Forward Design Build by emailing andrea@planforward.net Thank you again!

The main faucet is the Kohler Promaster 6330-CP
