A shower tray catches and directs water into the waste, helping protect the bathroom floor from leaks and water damage. Over time, a tray can become damaged, worn or difficult to keep watertight. If the tray needs replacing, you may not need to replace the entire shower cubicle. In many cases, you can replace the shower tray on its own, provided the new tray is compatible with the existing enclosure and plumbing. If you are planning more than a shower tray replacement, our bathroom renovation guide covers the wider work involved in updating a bathroom.

Can You Replace Just a Shower Tray?
Yes, it is possible to replace just a shower tray without replacing the whole shower enclosure. However, a few checks are important before you buy a replacement.
Check Compatibility With Your Shower Enclosure
Measure the existing tray carefully and check that the replacement will fit the current shower enclosure. The size, shape and position of the tray need to work with the existing screen or cubicle. Accurate measurements help avoid gaps, unstable fittings and problems when reinstalling the enclosure.
Check the Plumbing and Waste Connection
The new tray also needs to work with the existing waste pipe and drainage position. If the waste outlet is in a different location, some plumbing adjustment may be required. Poor alignment can result in leaks or drainage problems, so check the waste position before installation.
Check the Condition of the Enclosure
Replacing the tray alone may not be worthwhile if the existing enclosure is badly damaged, worn or no longer suitable. If the enclosure is in good condition and the replacement tray fits correctly, replacing just the tray can be a simpler option.
Shower Tray Materials and Sizes
Shower trays are available in different materials, shapes and sizes. The right choice depends on the existing shower area and type of installation.
What Are Shower Trays Made Of?
Common options include:
- Acrylic shower trays – lightweight and generally easy to handle and install.
- Stone resin shower trays – heavier and more durable, with a solid feel.
- Ceramic shower trays – hard-wearing but heavier and potentially more difficult to install.
What Sizes Are Available?
Common shower tray sizes include:
| Shower Tray Size | Typical Use |
|---|---|
| 1200 x 800mm | Medium to large shower areas |
| 1000 x 800mm | Small to medium shower areas |
| 800 x 800mm | Compact bathrooms and en-suites |
| 1700 x 700mm | Long, narrow shower areas |
| 1700 x 800mm | Larger shower areas |
Smaller shower tray options are also available for bathrooms where space is limited.
Tools and Materials Needed to Replace a Shower Tray
Depending on the installation, you may need:
- Utility knife for removing old silicone sealant
- Adjustable wrench or spanner for plumbing connections
- Spirit level for checking the tray is level
- Screwdriver for screws and fittings
- Bathroom-grade silicone sealant
- Suitable adhesive
- Waste connector
- Levelling materials if the existing base needs adjustment
The exact tools and materials will depend on the tray, base and existing plumbing.
How to Replace a Shower Tray
Replacing a shower tray involves removing the old tray, preparing the base, fitting the new tray, reconnecting the waste and sealing the edges.
Step 1: Remove the Old Shower Tray
Remove the shower screen or enclosure as required to access the tray. Carefully cut through the old silicone sealant and disconnect the tray from the waste pipe. Remove the old tray without damaging the surrounding tiles or plumbing.
Step 2: Prepare the Base
Clean away old adhesive, silicone and debris. Check that the base is stable, flat and suitable for the replacement tray. If the base needs adjustment, correct it before fitting the new tray. A stable, level base helps prevent movement, poor drainage and water pooling.
Step 3: Position and Level the New Tray
Place the new shower tray on the prepared base and check its position against the walls and enclosure. Use a spirit level to check that the tray is level. Make any necessary adjustments before securing it in place.
Step 4: Connect the Waste Pipe
Connect the tray waste to the existing drainage system and check the connection carefully. Test the drainage before completing the installation. Water should flow away freely without leaks.
Step 5: Seal the Tray
Apply suitable bathroom silicone around the joints between the tray, walls and surrounding surfaces. Allow the sealant to cure according to the manufacturer's instructions before using the shower. Allow at least 24 hours for the silicone to cure.
How to Silicone and Reseal a Shower Tray
A proper seal is important for preventing water from getting behind the tray or into surrounding areas.
How to Silicone a Shower Tray
- Use mould-resistant bathroom silicone.
- Apply an even bead along the relevant joints.
- Smooth the silicone with a suitable tool.
- Use masking tape if needed for cleaner edges.
- Allow the sealant to cure fully before using the shower.
How to Reseal a Shower Tray
If the existing tray is still in good condition but the seal has failed, you may only need to reseal it. Remove the old silicone, clean and dry the area thoroughly, then apply new bathroom-grade silicone. Remove mould, soap residue and debris before resealing.
When Should You Replace the Whole Shower Cubicle?
Replacing only the tray may not be suitable in every situation.
Consider replacing the shower enclosure as well if:
- The existing enclosure is damaged.
- The enclosure is worn and no longer seals properly.
- You cannot find a compatible replacement tray.
- You are already planning a wider bathroom upgrade.
If the enclosure is in good condition and a suitable tray is available, replacing only the tray can avoid unnecessary replacement work.
If replacing the tray is part of a larger bathroom project, our bathroom renovation services in London can cover the wider installation work.
DIY or Professional Shower Tray Installation?
A shower tray replacement may look straightforward, but mistakes with the base, waste connection or sealing can lead to leaks and further repairs. DIY installation can reduce labour costs, but you need the right tools and enough experience to deal with the existing plumbing and tray installation. Professional help may be useful where plumbing adjustments are needed, access is difficult, or the tray is large or heavy, such as a stone resin tray.
How to Ensure a Successful Shower Tray Replacement
Before starting, check the tray dimensions, enclosure compatibility, waste position and condition of the existing base. The replacement should sit securely, drain correctly and be properly sealed around the relevant joints. If the existing plumbing or enclosure needs significant adjustment, getting professional help can avoid problems later. If you are unsure whether your existing enclosure can be kept, a plumber can assess the tray, waste connection and surrounding installation before the replacement begins.
