Step-by-Step Guides to Cut a Square Hole in Porcelain Tile

  • Wax pencil
  • Tape or ruler
  • Eyewear
  • Dust mask
  • Air plugs
  • Rubber mallet

Follow these 7 steps to cut a square hole in porcelain tile:

Step 1: Preparing the Tile

Before you start cutting, make sure the tile is ready to be cut. This means removing grout or anything that might interfere with your cuts. You just need to use a grout saw and remove the grout.

Step 2: Measure the Sections

Use a tape or ruler measure to figure out where you need to cut your hole. Do it on both sides of the tile. When you flip it over, they should match.

For example, if you want to install a socket in the middle of the tile, you will need to measure two sections. The section that will be cut is part of the outermost square and is equal to the socket size plus its diameter.

Step 3: Mark the Sections

Mark lines on both sides of the tile. Use a wax pencil to mark the sections of your hole.

Step 4: Place the Tile on a Flat Surface

Place the tile on a clean flat surface. Make sure there is no debris between the tile and the surface so it can lay evenly.

Step 5: Wear Safety Gear

Wear protective eyewear, a dust mask for breathing protection, and earplugs so you won’t be bothered by the sound of your wet saw.

Step 6: Making a Plunge Cut

Hold it firmly and make sure there is no movement at all. Use the wet saw blade to cut inside the line about 5mm. Do this on all four sides of the section.

Start with a sharp edge and work your way down so you won’t overheat tiles. Be careful not to press the wet saw too hard on the tile in the line, or it will crack.

After making a plunge cut on one side, do the same thing on the other side. This time, make it deeper to make room for the blade for ceramic tile.

Step 7: Tap Out the Sections

After making plunge cuts on all four sides, tap out the sections using a rubber mallet or other instrument. A square hole will appear.
