Does Corian have any strength to hold screws?
My contractor put a piece of oak behind the towel bar in my bathroom. The reason for this is so the oak could be screwed to the studs and then the towel bar is screwed to the oak. He used the wrong finish on the oak and it is all full of water spots. My thinking is to replace the oak with Corian or similar if I can screw the towel bar to the Corian.
