You have a number of choices when installing bathroom wainscoting. They include prefabricated panels, tongue and groove slats, and tile. When comparing tile and wood options, a major consideration is the difficulty level of the installation. Aesthetically, both wood and tile wainscoting have their merits. What tips the scales is the professional assistance you need to complete the job.
Prefabricated wainscoting is the easiest type to install. It is made from MDF or some type of fiberboard; the installation involves no individual slats of wood or rows of separate tiles. Tile is probably the hardest to properly install because of the precise measurements required in addition to the correct method of prepping the backing board, setting, and grouting it.
