My cast iron enameled sink is not Kohler, but I had the same concerns before installing as I had also read about not including lead in the finish. At first I was super carefull, but over time I have become more comfortable with the sink. I haven't had any chips from regular use. There have been some "metal marks" which come out pretty easily with some lysol and a scotchbrite pad. We wash alot of cast iron pans which are easy to "ding" things with, but we are careful not place them in the sink, not throw. We don't have kids so that helps, however my husband is as hard on things as any teenager.

Thanks. I really would like to know if there is any truth to the idea of the lead being removed and the finish thus being less durable. Or, is this just one of those "I heard it on the Internet" anecdotes?

My eight year old Kohler is a workhorse, too. My greatest regret is that they don't have a color that will work in my reno. I have heard nothing from them or any suppliers to indicate a formula or finish change.

If I were you, I'd just call Kohler. They have always answered all my questions in a timely and honest manner. Phone: 1-800-4KOHLER(1-800-456-4537)
