Prova Waterproofing Shower Kit: Shower Tray, Bonding Flange, Waterproofing Membrane and Grate Assembly, Strainer, Joint Sealant

Product Features:

• Complete waterproof shower installation system. The Prova Waterproofing Shower Kit is a fully integrated bonded waterproofing system designed for tiled shower construction. The kit includes a pre-sloped shower tray, bonding flange drain, waterproofing membrane, grate assembly, strainer, and joint sealant, providing all essential components required to build a reliable waterproof shower base ready for tile installation.
• Pre-sloped shower tray for efficient drainage. The lightweight foam shower tray is factory-engineered with a precise slope that directs water toward the drain, helping prevent standing water on the shower floor. This design eliminates the need to construct a traditional mortar bed and significantly simplifies the installation process for contractors and renovators.
• High-performance waterproofing membrane. The included Prova waterproofing membrane forms the core moisture protection layer of the system. Installed directly beneath the tile covering, it creates a continuous waterproof barrier that prevents water infiltration into the substrate and surrounding structural materials.
• Durable polyethylene waterproofing membrane. The membrane is manufactured from high-quality waterproof polyethylene designed specifically for bonded waterproofing tile assemblies. Its construction helps block moisture penetration while maintaining dimensional stability beneath ceramic tile, porcelain tile, and natural stone tile surfaces.
• Bonded waterproofing technology. The waterproofing membrane is installed using thin-set mortar and bonds directly to the substrate and shower tray. This bonded waterproofing method helps prevent moisture from migrating beneath the tile surface, protecting subfloors, cement boards, and structural framing from water damage.
• Reliable connection with bonding flange drain. The included bonding flange drain integrates the waterproofing membrane directly into the drain assembly, creating a secure watertight connection at the most critical point of the shower floor. This design helps ensure water is directed safely into the drainage system without compromising the waterproof layer.
• Grate assembly for modern tile showers. The drain grate assembly provides a clean and professional finish that integrates seamlessly into tiled shower floors. The grate allows water to flow efficiently into the drain while maintaining a sleek appearance suitable for contemporary bathroom designs.
• Integrated drain strainer for debris protection. The included strainer helps maintain consistent drainage by preventing hair, debris, and particles from entering the plumbing system, helping reduce the likelihood of clogs and simplifying long-term maintenance.
• Joint sealant for watertight seams and transitions. The Prova joint sealant included in the kit is designed to seal seams, edges, and system transitions within the waterproofing assembly. It helps reinforce the waterproof layer at corners, connections, and drain transitions to ensure complete moisture protection.
• Designed for tiled shower systems. The Prova Waterproofing Shower Kit is compatible with ceramic tile, porcelain tile, marble, granite, and other natural stone finishes. The system provides a reliable waterproof base for residential bathroom showers, ensuite bathrooms, wet rooms, and commercial tiled shower installations.

Product Description:

The Prova Waterproofing Shower Kit is a complete bonded waterproofing shower system designed to simplify tiled shower construction while delivering reliable moisture protection in residential and commercial bathroom installations. This all-in-one waterproof shower kit includes a pre-sloped shower tray, bonding flange drain, waterproofing membrane, grate assembly, strainer, and joint sealant, providing the essential components needed to build a professional waterproof shower base ready for tile installation.

The system begins with a lightweight pre-sloped shower tray engineered to provide the correct slope that directs water toward the drain. This factory-formed slope eliminates the need for traditional mortar bed construction and helps ensure consistent drainage performance across the entire shower floor. Proper drainage is critical for preventing standing water and maintaining long-term performance of tiled shower assemblies.

The included waterproofing membrane forms a continuous waterproof barrier beneath the tile layer. When installed over the shower tray and integrated with the bonding flange drain, the membrane helps prevent moisture from penetrating into the underlying substrate, protecting subfloors, framing, and surrounding building materials from water damage. This bonded waterproofing method is widely used in modern tiled shower construction for its reliability and efficiency.

At the center of the system is the bonding flange drain, which creates a direct connection between the waterproofing membrane and the drainage assembly. This design helps ensure a secure watertight transition at the most critical point of the shower floor while allowing water to flow efficiently into the plumbing system. The included grate assembly provides a clean and professional appearance that integrates seamlessly with tile installations.

The strainer helps maintain proper drainage performance by preventing debris from entering the drain system, while the joint sealant is used to seal seams, edges, and system transitions throughout the installation. These components help ensure the entire shower assembly functions as a continuous waterproof barrier beneath the finished tile surface.

The Prova Waterproofing Shower Kit is designed for compatibility with ceramic tile, porcelain tile, natural stone tile, marble, granite, and other common shower floor finishes. When installed using appropriate thin-set mortar and industry-approved tile installation practices, the system creates a durable and dependable waterproof foundation for tiled shower floors in bathrooms, ensuite showers, basement bathrooms, and wet room installations.

Ideal for professional contractors, tile installers, and experienced DIY renovators, the Prova waterproof shower system offers a streamlined and reliable approach to building modern tiled showers while ensuring long-term waterproof protection and installation efficiency.
