Let me try again. I tried to post, but it got dropped, I guess.
What you should do depends alot on your tastes, what you think the buyers will like, and the style of the rest of the bath and the style/age of the house.
I would hit HD, Lowe's, Barnes&Noble, and the web and look at bathroom design magazines/books to see if anything catches your eye. Then you can copy what they did and modify to suite your tastes.
If it is an older house (say pre-1940), there may be some nice wood under there. I would strip the wood to see what you are working with. If the wood looks nice, a stain or just a protective finish would give you a nice natural wood look. We can't see what else you have in the area, so we can't tell if a wood look would be better than paint. Hardware also does a lot to change the look. You can easily go between antique to traditional to comtemporary just by changing hardware.
We can't say what we think will look good to you. That is your call. Some additional pics or information about the bathroom/house would at least give us a little direction to give ideas. The fastest/easiest way would probably be to flip through the bathroom magazines, though.
