Tile RIGHT demonstrates how to tile a diagonally cut tile. First set the Measure Right Pro to the appropriate setting, extending it from corner to corner along your tile. Account for your grout line and the space up against the wall. Then, lock the tool. Next, place the tiles you're going to use on top of your set tiles. Slide the Measure Right Pro along the wall and mark the tiles. Place the sections in the appropriate place. Then, cut your tiles. Lay the tiles where you've previously marked for a perfect fit. Grout the tiles as necessary to complete the project.
