So after going to four different plumbing stores, not to mention Lowe's and Home Depot, I finally found the faucet I was looking for. It was kind of busy inside the store due to there being a lot of plumbers, but I was quickly acknowledged and attended. The showroom was amazing! I will definitely be coming back!!!!
