We will never have double sinks again in our home. When we built this house 8 years ago we went with a single sink. Works for us. The doubles are too small to get a large skillet in. We never have rinsed in a separate sink. That doesn't seem sanitary to me. We use fresh water from the fawcet to rinse anything we are eating or cooking with, everything else goes in the dishwasher at home.
In the camper I wish we had a single sink that is smaller than most doubles but larger than what I call a bar sink. We have a utility room sink that seems about right to me.
