We currently have a kohler black cast iron undermount sink under granite countertops. My husband and I are beginning kitchen remodeling (want to keep the granite but switch the sink for same model but different color). I stopped by the place that installed our granite and sink and they said this is possible about 99% of the time. Have any of you done this? how difficult is this process? i know the sink must be epoxyed to the granite and then we have an undermout kit supporting everything. Is this going to be the nightmare I'm afraid of?
