Waterproof Backer Board for Shower

As a professional manufacturer with automated production lines and large-scale output capacity, we provide full OEM & ODM customization services for global building material wholesalers, construction contractors and hotel renovation project clients. Supported by mature composite pressing technology and stable raw material supply chains, we tailor shower backer boards to fit various overseas wet-area construction standards

This shower backer board adopts a three-in-one composite sandwich structure, each layer independently engineered for targeted waterproofing, load-bearing and surface protection

Core Waterproof Layer

We supply two mainstream waterproof membrane options for different project budgets： HDPE composite film and butyl rubber waterproof roll. HDPE material features compact molecular arrangement to block long-term water penetration efficiently. Butyl rubber membrane owns outstanding stretch and adhesion; hot melt welding can create seamless waterproof enclosure for tricky spots like corners and pipe cutouts. Our premium-grade boards add extra nano waterproof additives, which pass 72-hour continuous simulated shower leakage testing with zero water seepage;

Reinforced Support Core Layer

Three substrate alternatives are available： GRC glass fiber reinforced cement board, FC fiber cement compressed board, and high-density XPS polystyrene foam board. This composite structure strikes a perfect balance between structural rigidity and lightweight design. It holds heavy ceramic tiles firmly, withstands daily impact, and delivers extra thermal insulation to cut bathroom heat loss;

Surface Protective Top Layer

Two surface coating choices for clients to pick： acrylic resin coating and polyurea coating. Acrylic finish resists UV rays and long-term aging; polyurea coating comes with high surface hardness, anti-scratch performance and super hydrophobic property. Water stains, soap scum and dirt barely stick to the surface, cutting daily cleaning workload significantly

All three layers are tightly laminated under high-pressure molding to form an integrated, stable waterproof shower backer panel

Practical Construction & Long-Term Usage Advantages

Simple, Time-Saving Installation：

Our panels are manufactured under standard dimensions, and can be cut on-site to match any shower wall layout. Multiple mounting solutions are supported： direct adhesive bonding, buckle assembly, or keel fixing with expansion fasteners. Only basic special glue is required during installation; no complicated professional tools or skilled workers are needed. One single worker can finish the whole tiling substrate process, shortening overall construction cycle and lowering labor costs for projects;

Wide Temperature Adaptability & Long Lifespan：

We select premium raw materials that withstand temperatures ranging from -40°C to 120°C, coping well with frequent hot-cold shifts in shower spaces. The panel won't warp, swell or turn brittle after years of damp exposure. Accelerated aging lab tests prove its service life can reach 15–20 years under regular use, greatly reducing later maintenance and replacement expenses for commercial venues;

Ideal for Hotel & Hospitality Renovation Projects：

Hotel and motel shower rooms see heavy daily foot traffic, which sets strict standards for waterproof reliability, durability and visual finish. Our composite backer board stands up to mass guest usage, minimizes periodic maintenance work and slashes long-term operational costs. With customizable panel sizes and thickness options, it matches all kinds of bathroom interior design styles to boost space comfort and attractiveness

Flexible Size & Thickness Customization

Standard stock sheet dimension is 1220mm×2440mm, while thickness can be adjusted to suit different construction scenarios：

20mm thick board： Widely used on light steel keels with 60mm spacing or uneven concrete walls. It works with tile adhesive and fixing anchors to level rough walls rapidly;

Multi-scene application： Also fit for pipe wrapping, wall-hung toilet mounting base, wet floor partition paving and other customized wet-area construction parts
