This was a comment I contributed to elsewhere, which is relevant to this thread. This person is contemplating a single sink over a double-sink:
Until recently, I had double-sink forever. There was a deep sink to the left and a shallower sink to the right with a disposal. My cutting board bridged the smaller sink. As I prepped food, the debris would drop into the smaller sink. After I was finished, I would collect the vegetable bits for the compost. Some things would drop into the disposal, so I would occasionally turn it on.
When it came to bathing the cat, which is a rare event. I would fill the small sink with warm water to scoop onto her while she stood in the larger sink.
If the dishwasher was on the fritz, I would put soapy water in the small sink. When all the dishes were washed and placed in the large sink, I would rinse in the small sink and put the dish into the dishwasher.
The double sink was also useful when canning. The deep sink would be where my blanched tomatoes would go to cool. The small sink was where I did the peeling and trimming. I then had large containers to put the prepped tomatoes awaiting cooking or jarring.
The deep sink I have now had a raised rack maybe an inch above the sink's floor. I really didn't see why I needed this rack. When a visitor put it away with all my other racks last summer, I have yet to retrieve it. That rack made cleaning the sink a two step process. If any food droppings got caught on the rails, I would have to hand remove it sometimes.
If you are prone to back problems, do consider how deep you really want this sink to be. I saw a friend whose really too deep sink became a back strain issue.
I have a double-drawer dishwasher. I love the load-and-go versatility, because there is no reason for dishes to end up in the sink. What I do hand wash are pots and some baking dishes. When I make a casserole or lasagna, I put it in the dishwasher with stuck on food. It is clean as a whistle at the end of the cycle.
After thinking while writing, I find I prefer the two sink more to my liking. I had 47 years to develop a workable system. If I wanted to hide dishes from plain sight, a deep sink will cover a lot of territory.
