Don,
These are not the corian sinks - they are the molded fiberglass sink and countertops used in 2006 - 2007.
However - I remember the problem corian had with the sink cracks and I'm thinking it may still apply to these. I've seen the DW pour boiling water down there and I always worried about the tank and plumbing. I maybe should have been worrying about the sink itself.......now I'm going to have to tie her up and spank her for not listening to me
