Kitchen Cabinet Replacement
If the shape of the top is fairly simple(straight runs or short ells) you should have no problem. remove all appliances and the sink, as these cutouts are obviously the weak spot and you want as little weight as possible on the top. Coarian is usually just held in place with silicone, so a razor knife and carefull prying will get it loose from the bases after removing the splash. The material is brittle, so be careful. Also tilt it up and carry it vertically as it snaps easily if carried on the flat. If the top is trapped by it's shape, remove the splash and use a fine tooth blade in a reciprocating saw to cut it at the sink or cooktop cutouts. A corian installer can easily reseam this product and repolish the top while he is there...brand new top. Be sure to match the width of any fillers used in the cabinets, and a few pictures will go a long way to help remember things.
