Tina, I'm in the process of putting up wainscoting in our powder room. I happen to be using 1/4" beadboard from a company called PGM (WWW.PGMPRODUCTS.COM) on the material it states that it can be appliedover any wall in good condition. I would suggest a combination of both. I was able to pick this material along with the base trim and chair rail at Home Depot. They had it in knotty pine, oak, and cherry. Hoped this helped.
