Review on 🚰 Kraus KGU-413B Undermount Single Bowl Granite Kitchen Sink - 31 Inch Black: Premium Quality and Functionality by Robert Layne

First of all I was very impressed with the packaging and the price of this sink. The box was packed very securely so that the sink was not damaged. I couldn't find a sink this size anywhere for less than $200. What I don't like is that it's "80% granite construction". There is nothing about this granite sink other than its description. It consists of a woven fiberglass mat laminated in a mold. Perhaps the granite dust is mixed with the polyester or epoxy used to make this item, but it is definitely NOT granite. not of stone. This doesn't mean it's a bad buy or an inferior item as it's made out of composite materials and not stone, but if you're looking for a REAL granite sink then this unit isn't for you.
