This is obviously an old thread that's been resurrected but figured I'd give my 2 cents anyway. I just replaced my 20 year old Kohler cast iron sink with a Kohler stainless undermount. I would have gone with another cast iron but the Kohler white was on backorder and I couldn't wait that long. My 20 year old sink was in amazing condition considering the age and abuse it took. I had ordered a special cast iron sink cleaner from Kohler themselves that worked really well at getting utensil scratches out, but we too used a grid which definitely helped. I've also been told by many pros that things aren't "made like they used to be", whether that be flooring, cabinets or cast iron sinks, mainly because of changes in EPA/green standards. The toxic chemicals that were once used to say, varnish floors or coat sinks are no more because of the health hazards they cause their workers and the VOCs/chemicals they emit.

I noticed a crack in the front corner of our (less than) 6 month Kohler Whitehaven sink. Immediately a pit in my stomach! This sink was installed on 11/14/22. We spent a pretty penny remodeling our very dated kitchen and are thrilled with how it looks. We contacted Kohler whowhichwhowhowhichwho said they will replace sink. We are waiting to talk to someone about cost associated with reinstalling a new sink to replace a defective sink. Ours is undermount and don't feel as though we should be on the hook for this expense. Anxious to hear back from Kohler. If their product wasn't defective we wouldn't be needing to discuss cost associated with this repair.

Anyone out there have the Riverby?

I was at our Kohler store in July and was told they had just started production and would make white first to fill all the backorders, then they would start on the colors. They were estimating my sink (color) would be 4 months, so November delivery. I ended up switching my plans and am going with a white sink , which I ordered from Wayfair since Kohler was still 8 weeks out.
