Wetwall Corner Shelf Installation Guide

11 May 2026, 11:05 AM

View the official Wetwall corner shelf installation guide online using our interactive flipbook. Wetwall corner shelves are a practical and stylish way to add storage inside your shower or bathroom without the need for bulky external fittings. Designed to work seamlessly with Wetwall wall panels, these shelves provide a clean, modern finish while maintaining a fully waterproof system.

The Wetwall corner shelf installation guide outlines the key steps to ensure a secure and long-lasting fit. This includes choosing the correct location, ensuring the corner angle is close to 90°, and dry fitting the shelf to avoid gaps before fixing. The guide also explains how to prepare the surface, apply colour-matched sealant, and support the shelf during curing using temporary blocks.

For best results, the shelf should be installed onto clean Wetwall panels using the recommended sealant, ensuring full contact along the rear edges. Once installed, the shelf is secured with tape while the sealant cures, typically within 24 hours, creating a strong and waterproof bond.

At Rubberduck Bathrooms, we stock a wide range of Wetwall corner shelves, panels, and accessories to help complete your bathroom project with a professional finish.
