I'd stay with chrome.

When you look at images of bathrooms in HOUZZ, you will notice that it is rare for different metals or finishes to be used together.

It is customary to keep everything the same, so another vote for chrome.

Thanks all. I did decide on chrome after all. I couldn't find Chrome sconces I liked at any retailer, just one in the antique nickel and another in polished nickel. Thus my dilemma. So I went online and am having these shipped here to Canada from the US. Thanks for your input.

very cool! Thanks for sharing!
