Matching Nickel and Gold Finishes in a Bathroom

Why don't you just get some sort of accessories that have both colors or get accessories in both? Then it will look like you intended to mix and match. Or -- change the knobs and drawer pulls to match one or the other? Are the taps and such gold as well? If they are chrome, I wouldn't worry about the other two metallics matching.

Personally, I wouldn't worry about it.

You could try spray painting the nickel finish with gold paint, but I don't know how it would hold up in the humid atmosphere of a bathroom. Can you just live with it not matching?
