In the kitchen we are planning, there is a main sink in the island and adjacent to that, there is a butler's pantry which goes into the dining room. Since our kitchen is not very large and the island with the main sink is right across from the range, we figured it would be a good idea to have a second sink in the butler's pantry so that one person could cook and another could prep and/or clean in there. We will have a dishwasher next to both sinks.

Now here is the dilemma. We originally planned to have fireclay sinks for both areas however, we were hoping to get a large sink in the butler's pantry as well and I have not found a non-apron front sink that will fit in a 24" cabinet but is larger than the little 15x15 option.

Kohler does make a cast iron sink that is 20x20 which would be perfect. We prefer the larger size because it will be easier to wash dishes in, etc.

Would it be bad to have them be two different brands? If so, should we get a cast iron sink in the main kitchen to match a larger one in the BP or should we get the fireclay sinks in both but have a smaller one in the butler's pantry. I am OCD and would probably notice if they were significantly different but probably not so much if they were only slightly different
