My home is a modest one in a rural area. I am considering installing granite slab countertops in my kitchen. I have a small area to cover. I can purchase the slabs directly and have direct cuts made from the supplier. My plan is to hire a contractor to install the countertop. My question is this... is it absolutely necessary to purchase an undermount sink for granite counters? I have a stainless steel double sink now that is in fantastic shape. If I must have an undermount sink then that is what I will do, but I would appreciate some advice from others with some experience. Thanks!

undermount sink necessary for granite slab?
