I’d use a darker wall paper. I think it’ll give that wow factor you’re looking for. Are you open to patterns? You can choose a wall paper with some gold in it too.

I thought of this paper I saw on CB2 recently, I think it would look awesome in there (in any of the colors) —

Of course I’m not sure what styles you like, decor in rest of house, etc. Just basing this on that good-looking, modern sleek vanity and the floors. I think this paper definitely has the wow factor … while being elegant and sophisticated, instead of jarring.

Another I like, but I think it’s a bit more design specific:
