Cutting Tiles Already Laid: A Step-by-Step Guide
So, you've found yourself in a situation where you need to cut tiles that are already on the floor. Whether it's due to a change in layout or a repair, it's a task that requires precision and the right tools. Don't worry, it's entirely possible, and we're here to guide you through the process.
Why You Might Need to Cut Laid Tiles
There are several reasons why you might need to cut tiles that are already laid. Some of the most common include:
- Changing the layout of a room
- Repairing damaged tiles
- Installing new features, like a shower or a new sink
Tools You'll Need
Before you start, ensure you have the right tools for the job. Here's a list of what you'll need:

- A tile cutter or nippers
- A utility knife
- Scoring tool
- Masking tape
- Safety glasses
- Thinset mortar
- Grout
Preparation: Marking and Scoring
Before you start cutting, you'll need to mark out where you need to cut. Use a pencil or a marker to draw a line where you want to cut. Then, use a scoring tool to score the tile along the line. This will make it easier to cut.
Using a Tile Cutter
If you're using a tile cutter, place the tile in the cutter with the line you've scored against the wheel. Apply even pressure and cut along the line. Be careful not to apply too much pressure, as this can cause the tile to crack.
Using Nippers
If you're using nippers, place the tile on a hard surface. Hold the tile firmly with one hand and use the nippers to cut along the scored line. This method is more labor-intensive but can be useful for small cuts or intricate shapes.

Cutting the Tile
Once you've scored and cut the tile, you'll need to break it along the line. You can do this by placing the tile on a hard surface and applying pressure to the scored line. The tile should break cleanly along the line.
Reinstalling the Tile
Once you've cut the tile, you can reinstall it. First, remove any old thinset or grout from the back of the tile. Then, apply a new layer of thinset to the back of the tile and press it firmly into place. Allow the thinset to set according to the manufacturer's instructions.
Grouting
Once the thinset has set, you can grout the tile. Apply grout to the joints between the tiles, using a grout float to force the grout into the joints. Allow the grout to set according to the manufacturer's instructions, then clean off any excess grout.
Safety Tips
When cutting tiles, it's important to prioritize safety. Always wear safety glasses to protect your eyes from debris. Also, be careful not to cut yourself on the sharp edges of the tile. Consider using gloves to protect your hands.
When to Call a Professional
While cutting laid tiles can be a DIY job, it's not always the best option. If the cuts are complex or the tiles are particularly fragile, it might be best to call a professional. They have the tools and experience to get the job done right.
Remember, cutting laid tiles is a delicate task. Take your time, be precise, and don't rush. With the right tools and a bit of patience, you can cut laid tiles like a pro.
