Some photos of possible finishes and the faucets that have been chosen for the two rooms.

I'm a fan of mixing metals and don't think there are any hard and fast rules. Instead, it has a lot to do with the specific kitchen, location of the hardware, spacing. Yet, I don't like the idea of brass faucet with the stainless apron. I think the stainless apron dictates chrome or nickel, either brushed or polished.

Thanks Kendrah. I was concerned about having a brass faucet and feel more comfortable with a nickel faucet but brass was being suggested to me as ok. I appreciate your input.

Brass would be ok if you just had an undermount stainless sink and not the stainless apron front sink.
