Understanding Shower Trays and Riser Kits: When Do You Need One?
When planning a bathroom renovation or a new build, one of the key decisions you'll need to make is whether to use a shower tray and, if so, whether you need a riser kit. This article aims to provide a comprehensive guide to help you understand these components and make an informed decision.
What is a Shower Tray?
A shower tray is a basin-like structure that sits at the base of your shower, designed to collect water and direct it towards the drain. They are typically made from materials like acrylic, stone resin, or stainless steel, and come in various shapes and sizes to fit different shower enclosures.
What is a Riser Kit?
A riser kit, also known as a shower tray riser or shower base riser, is a platform that elevates your shower tray to a desired height. They are usually made from plastic or metal and can be adjusted to suit your specific needs. Riser kits are often used to create a level or raised shower floor, or to accommodate uneven surfaces.

When Do You Need a Riser Kit?
Riser kits serve several purposes, and their need often depends on your specific bathroom layout and requirements. Here are some scenarios where a riser kit might be necessary:
- Uneven Floors: If your bathroom floor is uneven, a riser kit can help level out your shower tray, ensuring a safe and comfortable showering experience.
- Desired Shower Height: Some people prefer a higher shower tray for accessibility reasons or simply because they prefer a higher showering position. A riser kit can help achieve this.
- Waterproofing: In some cases, a riser kit can help improve waterproofing by creating a better seal between the shower tray and the floor.
- Drainage Issues: If your bathroom has drainage issues, a riser kit can help raise the shower tray and improve water flow towards the drain.
Types of Riser Kits
Riser kits come in various types to cater to different needs. Here are some of the most common types:
| Type of Riser Kit | Purpose |
|---|---|
| Adjustable Riser Kit | Allows you to adjust the height of the shower tray to suit your specific needs. |
| Fixed Riser Kit | Provides a set height increase for your shower tray. |
| Tray and Riser Kit Combo | Includes both the shower tray and the riser kit, ensuring a perfect fit. |
Installing a Riser Kit
Installing a riser kit typically involves the following steps:

- Measure your bathroom floor to ensure the riser kit will fit correctly.
- Prepare the floor by ensuring it's clean, dry, and even.
- Assemble the riser kit according to the manufacturer's instructions.
- Place the shower tray onto the riser kit.
- Connect the drain and ensure it's properly sealed.
- Test the shower to ensure it's draining correctly.
Conclusion
Whether or not you need a riser kit for your shower tray depends on your specific bathroom layout and requirements. By understanding what a shower tray and riser kit are, and when you might need one, you can make an informed decision that will enhance your bathroom's functionality and aesthetics. Always remember to measure carefully and follow the manufacturer's instructions for the best results.
