Kohler K8689-5U Undermount Single Basin Kitchen Sink

We installed this 5 years ago on a remodel and had looked at the 9" depth in the store and decided on that one. We didn't realize right next to it was the 5" depth and when we went back to order at the plumbing store, accidentally just pointed the 5" depth out in a rush to get it ordered. When it arrived, the plumber pointed it out and said we would hate it and offered to return and reorder, but we had already waited 3 weeks for this one and were eager to be done with the remodel so we opted to keep it. We are 5 years in and wish we had paid more attention and listened to our plumber. The sink, while lovely and works, is not deep enough to counter splashing when washing hands, pots, etc. and so as a result the granite around the sink is already showing signs of hardwater stains that we will have to pay to have polished out. This is a sink more for a side in the kitchen to hand wash vegs, etc in and not for utility /main sink.
