I want to play devil's advocate for a minute with the Corian marble shower case. We had corian counters and one day out of the blue, one cracked. Let me tell you, that sounded as if a gun had gone off in the kitchen. It was loud as h*ll. Sent Mr Schnick diving for cover in the living room. We weren't in the kitchen at the time and there were no hot items on the counters. Not that I think the daughter was innocent in this case, but I did wonder because everyone remarked on how loud it was.
ETA - We found out later that any bad thing done to the "marble" at any time can lead to failure later. The thing is, that it almost always fails at the time of the bad thing. Thanks prior renters for shortening my life.
