We are having granite installed in three rooms, and this moring I realized that our dishwasher is bolted to the underside of our formica countertop. In other words, there isn't any structure above the dishwasher other than the counter top. Is this normal??? I'm wondering how they are going to install the granite over that open space, and how my dishwasher will stay in place. Do I need to scratch the idea of granite and get a upgraded formica?
