When I took the sink out of the shipping box there was a strong, unpleasant odor. Two weeks later the smell was still there. The day before the sink was to be installed I realized I had to do something. I pulled off all the rubber material on the underside of the sink, (put there for sound deadening), and removed the glue holding the rubber on. Finally the smell was gone and the sink was useable. Had I not removed the sound deadening material, the under mount sink would have been a disaster.
