When tiling your bathroom, you need to trim tiles, particularly around the shower head, toilet base, and other round fixtures. For this job you need an electric tile cutter, as it is very difficult to use manual cutting tools. An electric tile cutter consists of a specialized electrical circular saw, held in water, to make cutting easier and to render a perfect cut.
It will reduce time spent trimming and obtain impeccable results. Because these saws are expensive to purchase, it is better to rent a unit. Read the instructions carefully, use heavy gloves, and wear eye protection.
Step 1 - Cut the Tile, Measure Circle
Measure the shower head. Use a marker and compass to draw a circle on the tile. Score the tile from the center. Now it's time for the wet saw.
Place water in the base of the tool to avoid overheating the saw. The water will also keep the tile from kicking out dust and cracking.
Power the machine and observe the spray of water around the blade. At this stage, use a discarded piece for practice. Once you are confident about how to handle the wet saw, cut the tile in half.
Step 2 - Cutting Around the Circle
Slowly introduce the half-tile to the blade and cut straight lines adjacent to the circled line. Continue until you have carved the rough shape of the circle. Allow .5-inches between each cut.
Step 3 - Using the Tile Nipper
Use a tile nipper to remove the excess material. Clean the shape of the circle. Using the wet saw in a circular motion, move the tile slowly, smoothing the edges.
Step 4 - Joining the Tiles
Now employ the same technique to the other half of the tile. Once the two halves match with a perfect circle in their center, place the two halves of the tile surrounding the shower head. Smooth the edges until you attain a perfect match. Should there be a small gap, do not worry. The grout will hide minor defects.
