There are many examples on houzz of contrasting counters for perimeter and island. For example butcher block on island and stone on perimeter or a solid color on one and something with movement on another. I would only mix two stones if one had movement and one was fairly solid. The stainless on perimeter and something else on island sounds good to me. Here is a pic of stainless counters with what looks like a stone breakfast bar. (I hope I understood your question right). http://houzz.com/photos/3137660

~$400 including expedited shipping. My GC just had his regular countertop guy do them, which wasn't great.... he had trouble making clean cuts. If I were going to do it again I would have pressed for someone with expertise to cut them. You can see in the image that the facing is not made of the stone peak, because too much was broken during the cutting to make the mitered edge. I'm a little bummed, but mostly pleased with the surface (which is the important part) thus far.

I like the tiny shelves idea because that way you have more storage for your things.

Hi Davina, either way would look good, so don't stress about it too much. This is a similar set up to our kitchen and I went with A & B both tiled and haven't regretted it. It looks generous and is more practical. Tiles are best around food prep areas as they are easier to clean than a painted wall ... you think that the splash back is what gets the most dirty but the walls around it get their share of splashes as well. In terms of suggestions for tiles - we went with a white textured subway - boring I know, but classic. Using a darker grey grout to match your bench would look good. All the best with your renovation!
