How do I prevent leaks under the resin tray?

Properly installing a resin shower tray is essential to ensure your bathroom remains water-tight. Preventing leaks beneath the tray not only protects your floor but also avoids potential long-term damage.

Preparing the Subfloor

Before positioning your resin tray, make sure the subfloor is both clean and completely level. Any deviation can create gaps where water might pool and eventually leak. Take time to check for dips and use a suitable levelling compound if necessary to achieve a flat surface for the tray to rest upon.

Sealing All Edges with Silicone

Once the tray is securely placed, seal every edge with a high-quality sanitary silicone. This process creates a flexible barrier that blocks water from escaping, even as surfaces shift subtly over time. Work methodically, pressing silicone into each joint, especially where the tray meets walls or surrounding materials. The River-Table Complete Kit includes silicone suitable for sealing in resin installations, which can be handy if you’re undertaking a DIY tray or similar project.

Routine Checks and Maintenance

Even after a careful installation, it’s important to periodically inspect the tray’s seals. Look for peeling or mildew, and reapply sanitary silicone as needed. Regular checks help you catch minor leaks early, maintaining the tray’s performance and your peace of mind.

When This Matters Most

Attention to leak prevention is especially crucial in highly used family bathrooms or where underfloor heating is present. Protecting the subfloor from water ingress here can prevent expensive remediation later on.
