I had bought 2 the top is not stone. out of the packaging, one had a chipped corner and before installing you can see white under the grey.  On the second one,  we left water in the sink overnight to help the sink set after attaching. In the morning teh paint was all bubbles! Also, there is no overflow which in canada is illegel.  Wayfair are being fair with helping me out. Im replacing the counter with quartz.
