How to Cut a Cuttable Shower Tray

Cuttable shower trays are a great solution when your bathroom has awkward sizes or tight spaces. They give you the flexibility to get a perfect fit inside your shower enclosure without needing a made-to-measure tray.

In this guide, we’ll walk you through how to cut a cuttable shower tray safely and accurately.

Important: Not all shower trays can be cut. Always check with the manufacturer before you start.

What You’ll Need

Before you begin, make sure you’ve got the right tools:

• An angle grinder with a diamond blade (or tile cutting blade)
• Masking tape
• A pencil or marker
• Water (to help keep dust down and cool the blade)
• Protective gear (gloves, goggles, dust mask, ear protection)

Make sure the shower tray is placed on a flat, stable surface and fully supported to avoid any cracks or damage while cutting.

Step 1: Measure Properly

This is the most important step. Always remember: measure twice, cut once.

Double check all your measurements before cutting. If you cut too much off, there’s no going back. Also, think about where your waste (drain) will sit after cutting and make sure it won’t clash with joists or pipework.

Step 2: Mark Your Cut Line

Once you’re happy with your measurements:

Apply masking tape along the line where you plan to cut
Draw a clear straight line on the tape

The tape helps you see your line more clearly and can reduce chipping when cutting.

Always cut from the top side of the tray, not the underside.

Step 3: Cut the Shower Tray

Now you’re ready to cut.

Put on your protective gear
Carefully follow the line with your angle grinder
Take your time and don’t rush the cut

Using a bit of water can help reduce dust and keep the blade cool while cutting.

Step 4: Smooth and Clean

Once the cut is complete:

Check for any sharp or rough edges and smooth them if needed
Wipe down the tray, especially the underside, to remove dust and debris

This helps make sure the tray sits properly when installed.

Ready to Install

Once your tray is cut and cleaned, it’s ready to be fitted into place.

Final Tip

Cuttable shower trays are designed to make installation easier, but every product can be slightly different.

Please check your own shower tray’s instructions before cutting to make sure you follow the correct guidelines for your specific model.
