Overview Customized XPS Tile Backer Board Products provide ready-to-tile solutions for bathrooms, shower rooms, steam rooms, wellness facilities and other wet-area construction projects. The product range includes preformed shower benches, flexible curved construction boards and L/U-shaped panels for pipe cladding, shelving, niches and decorative structures. Dimensions, thicknesses, angles, profiles and surface treatments can be customized according to project drawings. These products are suitable for bathroom system suppliers, tile distributors, building material importers, contractors, prefabricated bathroom manufacturers and private-label brands seeking flexible OEM solutions.

1. Preformed XPS Shower Bench The Preformed XPS Shower Bench provides a lightweight, waterproof and tile-ready base for built-in seating in showers, bathrooms and steam rooms. Available designs include straight benches, curved-front benches, corner benches and benches with integrated backrests. The bench can be installed more quickly than a traditional masonry structure and can be cut or adjusted on site when necessary. Its cement-coated surface provides a suitable substrate for ceramic tiles, porcelain tiles, mosaics and natural stone. Available Designs Rectangular shower bench Curved-front shower bench Corner shower bench Shower bench with backrest Wall-to-wall shower seat Custom bench based on drawings or samples 2. Flexible / Curved XPS Construction Board The Flexible XPS Construction Board is designed for creating curved tiled surfaces. Grooves formed in the board allow it to bend while maintaining a stable, reinforced surface for tile installation. It can be used to construct curved walls, rounded partitions, columns, arches, spa features, bathtub surrounds and other architectural details. Cross-grooved and longitudinally grooved versions are available for different bending directions and installation requirements. The flexible board combines low weight with moisture resistance, thermal insulation and easy processing. It reduces the time required to form curved structures and helps prevent problems caused by unstable or complicated multi-layer substrates.

3. L/U-Shaped XPS Panels L/U-Shaped XPS Panels are preformed construction elements developed for pipe boxing, shelving, wall niches, concealed installations and decorative tiled structures. The panels combine a strong cement-coated surface with a lightweight XPS core. Preformed 90-degree angles simplify installation and help create clean, consistent corners. The panels can be cut to the required length and fixed using suitable adhesives, fasteners and waterproof joint-sealing materials. L-shaped panels are suitable for external corners, shelves and single-sided pipe enclosures. U-shaped panels provide a convenient solution for boxing pipes, covering service lines and forming three-sided decorative structures.
