I just put in stainless steel sink with bronze faucets. Houzz.com came up. I narrowed the search to Kitchens and lots of photos came up. Because the faucet is in the countertop and no directly on the sink, it doesn't look bad at all. Check it out and see how you like that look!

I was told by a saleslady at my high end plumbing showroom not to mix faucet finishes. I think if you start paging throught kitchen idea books you will see that the finishes on multiple faucets in a kitchen are all the same. It is ok to mix in finishes on other items such as hardware and lighting, but you should have something to unify the different finishes.

I think either would go.. but looks like I'm ODD Man Out...I vote the oil rubbed bronze... I think the decision should be ..Whichever faucet you really love in whichever finish...

We are finishing up on our new build kitchen and will have all stainless appliances and sink with ORB faucet. I also have warm colors and somewhat of a rustic theme with warm tile floor and stained knotty alder cabinets. I have seen ORB faucets with stainless sinks in person and in my opinion it looks good as long as it coordinates with the rest of the room such as with lighting and knobs ( also what I'm doing)....and its best if the sink is undermount so the faucet is not touching the sink. Here's a picture of my sink without the faucet; I will try to post again when faucet and lighting is in. I hope that helps :)
