We bought a bunch of subway tile off of craigslist to retile our kitchen backsplash and wall. The previous owner had bead board up. When we pulled off the bead board we were not thrilled to find a destroyed wall behind it. Some places the wall seemed to have no support, other places were just holes with insulation stuffed in. I reinforced the wall with 1/4″ hardie backer board. As the additional thickness of the hardie board, thinset and tile was more than that of the bead board I also had to replace the bottom piece of trim on the window above the sink with an old piece of trim from the house, that wasn’t tapered in such a way that the tile would come out farther than it on the wall (as the existing one was). Then Lindsay rented a tile saw and went to tiling, while I was out of town. We also used grey caulk to finish the look and match the grey grout. We are very happy with the results both in look and durability!
