My husband and I are about to tackle a do-it-yourself installation of granite countertops as seen on the DIY network. My question is about our sink. We have a very expensive, oversize Kohler cast iron sink that we would like to keep. The problem is that it is a "tile in" sink, not a drop in or an undermount. Is there any way that we can install this sink with the granite slab and mount it flush as it is supposed to be by working with the underlying durarock or mounting options? It is a shame to get rid of this beautiful sink that is in great shape, just the wrong mounting type for granite. I would appreciate any ideas!
