I want to have my existing under mount stainless steel sink replaced with a granite sink. Will my contractor have to remove the countertop to do this or will he be able to do this from under the cabinet? I have a garbage disposal and a reverse osmosis water filtration system also under the sink. Obviously he will have to disconnect the garbage disposal and water filtration system but will he be able to lower the sink at that point and will he be able to wiggle in the new sink without removing the whole countertop. It seems like such a big job to remove the whole countertop. Should I be afraid that the Silestone will crack or break if attempted t take off the cabinets?
