Tiles come in one general square shape.There are some hexagonal tiles and octagonal tiles, but most will be simple squares. When tiling around pipes that come through a wall, or around a toilet base, these tiles must be cut. The project is something a DIY homeowner will accomplish with a few basic tile cutting tools. It will take just a few minutes to cut each tile. If you have a large number of cuts to make, expect to spend up to an hour or more on the job.
Set the bottom edge of the tile into position below the pipe where it will be installed on the wall or floor. Lean it forward until the tile comes in contact with the pipe or toilet.
Make a mark on the tile with a marker at the point where the pipe or toilet comes in contact with the tile.
Remove the tile from the wall or floor. Measure from the edge of the last installed tile to the edge of the toilet with a tape measure. Measure this distance on the far edge of the tile and make another mark with the marker. Now you have two marks showing the two points at which the pipe or toilet intersects with the tile.
Draw a straight line connecting the two marks. Then insert the tile into a wet saw and cut the tile along the mark. You can also score the tile along this line (on the shiny side of the tile) with a tile cutter and ruler. Then snap the tile in your hands. It will break along this line.
