Beadboard crops up in cabinets and on ceilings and often covers a whole wall. However, you are likely most comfortable with it as beadboard wainscoting in the bathroom. In other words, the beadboard comes about 1/3 up the sides of the wall, using the chair rail at the top and the baseboard at the end.
A cheap replacement for ceramic tile, beadboard is a excellent selection for bathrooms because it is relatively long lasting, can be colored any color, and can be set up at any level. While you frequently see it in conventional or traditional bathrooms, bead board does not have to provide a pretty country feel. It can be absolutely modern and nice. And on top of that, beadboard can add a fresh visible contrast to any remotely blah bathroom.
