Marmox Bath Panels

Waterproof, Tile-Ready Bath Panels

Marmox Bath Panels are waterproof, tile-ready panels designed to deliver a clean, durable, and professional finish to built-in baths. Manufactured with an extruded polystyrene (XPS) core and reinforced cementitious coatings on both sides, Marmox Bath Panels provide a reliable alternative to traditional bath framing and plasterboard solutions.

Lightweight yet robust, Marmox Bath Panels allow tiles to be applied directly to the surface, creating a seamless finish that integrates perfectly with modern Australian bathroom systems.
