American Standard Studio Carre Undercounter Sink with Mounting Kit in White

Great product. Converting a single sink vanity to a double and this was the perfect size.

I have three of these sinks. Bought one in 2008 or 2009. I loved the look and no issues. I bought two more in 2016 & at first glance it looks the same, but it is not. The first issue we had was finding out from a granite countertop fabricator that the sinks were not square, ie the sides of the sink/front to back, were not parallel to each other. Luckily, the fabricator had requested I deliver the sinks to them before they cut the sink holes in the granite. They were able to adjust the cut to make it work. Now that they are installed, I realized there is a flat spot on both sinks, right where the water hits. It makes the water drain very slow in that one spot and I am battling bad lime stains because of it. In addition, lime stain spots happen all over the sink, unless I wipe it dry each use. The original sink I purchased was square, does not have a flat area on the bottom, and I have never had an issue with lime stains anywhere on that sink. I imagine that the new company that owns this brand changed the manufacturing process and/or the location they are manufactured, and the quality control is not as good + they have changed the glazing or similar so that the water does not drain the same and leaves bad lime stains everywhere. The design is great, but I wish I had purchased a different sink.
