This may be a dopey question, but I am not overly sure what is meant by this. We are having our kitchen replaced next year and therefore we are shopping for new sink, faucets, cabinets ect. But for the sink that we have chosen, it states that it is recommended for a minimum 36" cabinet. Is that the depth of the counter top, or how deep it should be under the sink to the bottom of the cabinet below it? What exactly is meant by recommended for a minimum 36" cabinet?
