Waterproof Backer Board for Shower Walls

As a professional manufacturer with full independent production lines, we supply tailor-made OEM and ODM waterproof backer boards for shower enclosures, bathrooms and all wet-area construction projects. Supported by mature production technology and large-volume mass production capacity,we flexibly adjust product specs to match global clients' local construction standards

All panel dimensions, thickness, surface treatment and packaging labels can be adjusted per your local market requirements. Unlike generic fixed-size boards on the market, we tailor thickness specifications to match different wall load-bearing, insulation and waterproof project standards across Europe, Southeast Asia, Middle East and other overseas regions. Standard blank sheet size 1220*2440mm is available from stock for quick delivery

Our waterproof shower boards are versatile for all construction scenarios, from small-scale domestic bathroom refurbishments to large commercial building wet area projects. Size and thickness are fully customizable to meet your project demands; the standard 1220*2440mm sheet is just one option, and we produce panels with variable thickness as required by your site design

Core Waterproof Performance
The standout feature of our backer board lies in its integrated waterproof membrane layer, with two premium material options for different project budgets and application scenes：
HDPE composite waterproof film：Dense molecular structure delivers outstanding water impermeability, capable of long-term full immersion without water penetration;
Butyl rubber waterproof membrane： Features great stretch elasticity and ultra-strong bonding force, closely fitting irregular wall sections such as pipe penetrations, internal and external corners. Panels can be joined via heat fusion welding to form fully seamless, continuous waterproof layers

The multi-layer composite waterproof system works together with matching waterproof sealing strips for joint treatment, reaching an IPX7 full waterproof grade or above. Long hours of shower water spray and standing water will never seep through the panel to erode wall base structures. It eliminates property loss and cross-unit disputes triggered by bathroom leakage, a critical advantage for apartment buildings, hotels and factory dormitories;
Commercial spaces like factory staff restrooms have far stricter operating conditions: frequent heavy water flow, long-hour usage and complex pipe layouts. Our shower backer boards boast rigid structural strength and stable long-term waterproof capability, holding up well under years of heavy daily use without performance degradation

Reliable Supporting Substrate Layer
We provide three types of core supporting substrates for selection： glass fiber reinforced cement (GRC), fiber cement compressed board (FC), and high-density XPS polystyrene foam core
GRC & FC solid cement core panels： High compression and bending resistance, able to bear heavy tile, stone and decorative cladding weight, resistant to daily knocks and impacts;
XPS foam composite panels： Lightweight for faster manual installation, with extra thermal insulation effect to reduce bathroom heat loss

Practical Cost & Quality Advantages for Buyers

Simple cutting, fitting and fixing processes drastically cut down on-site labor hours and later maintenance costs for commercial property operators. Every batch of panels undergoes strict pre-shipment lab testing： simulated continuous shower spray testing for 72 hours with zero water seepage detected, ensuring consistent quality for overseas bulk orders;

We welcome global distributors, construction contractors and bathroom renovation suppliers to discuss custom OEM branding, size modification and mixed container order cooperation
