Polished nickel meets stainless steel in our kitchen sink. Polished nickel has a warm undertone. This is why it pairs really well with brass. If you already have a lot of brass, and you're ready to start mixing metals, start with polished nickel. Almost all of the faucets in our house right now are polished nickel.
