Shop here all the time. They have a super duper smart and awesome sales staff that know almost everything. They carry just about everything. Little more expensive on some items but more or less average. Delivery is super fast. Maybe for me cause our company is special.

Before heading to home depot, check out a place like this where the professionals shop. Cal Steam carries some great classic bathroom fixtures in stock at reasonable prices. I needed to buy a pedestal sink in the am to be installed that afternoon, and they had the Kohler Memiors sink in stock for $300. (and even loaded it in my car). It is not a showroom experience, but if you know what you want, Cal Steam is extremely efficient and reasonable.
