Can I install beaded-board paneling over ceramic tile?
Yes and no. You can install something over ceramic tile, but I would not recommend it. Depending on the area I would not recommend beadboard. If you are considering an area near a stove or other cooking surface, I would recommend formica instead. Any wood surface near a stove would not be good and a wood surface is not easy to clean, when you consider the texture and the grooves. I sugget you remove the tiles.
