I think the only door hardware I would worry about matching would be the hardware on the inside of the bathroom door.

If you like a different finish for in the bathroom, I don't think there is anything wrong with using that different finish for the interior handle as well.

Are your faucets exposed to the rest if the room, a glass wall walk in shower? It is just as easy to find nice Antique Bronze faucet do, I guess why not have the finish consistent. Our customers tell us the antique bronze is much easier to keep clean than chrome in the bathroom.

Satin Nickel is the new polished brass/chrome. It has been the go-to / popular finish for many years, similar to polished finishes of the 80s & early 90s. It's still a great look, but the antique type finishes are making a strong comeback - the look of antique pewter, bronze or vintage brass is timeless, refreshing and beautiful, so you can't really go wrong. Also, you don't see it often enough, but mix/match of finishes is catching on as well. Most people would argue that finishes must match on fixtures, however, we are seeing more and more pro designers mixing, especially the polished with "matte" finishes.
