I would like to add beadboard wainscoting in my basement bathroom in my 1950's home in Virginia. It will be painted. I want to use a species/material that is authentic to the period and style of the home, but I also want it to be maintenance-free. It seems my options are primed white pine or PVC, 1 x 6 x 1/2" thick. The PVC seems to be the better choice for areas with moisture. My question is: is PVC "cheap" or inappropriate? (The sheets of pine beadboard look rather cheap to me.) Also, there do not seem to be many options for baseboard or chair rail/caps in PVC -- but maybe I just didn't ask the right questions at the lumber yard today! Thanks!
