I have remodeled kitchens in 3 houses -- I prefer stainless sinks because I tend to chip porcelain
. I wound up doing my own redesign because I got tired of fighting with designers over what would work for me. In my first remodel, I did not have much room so I replaced a single sink with a large+small double sink - it was OK but the small side was only good for putting stuff in the garbage disposal and because of the size I could not rinse anything very big in it. My second remodel had a lot of room (and custom cabinets) and I got a double sink that had one large deep side on the right and one shallow side (the garbage disposal in the shallow side). I loved that sink. This house had to be a cheap, fast remodel and I was restricted in the size of my sink by the size of the cabinets so I got a double sink that has the same side sinks - they are OK but I wish they were bigger. I am glad I got the double. I am right handed but both sinks have had the left sink for washing, the right sink for rinsing and garbage disposal and dishwasher on the right.
