The Hydraset Onyx Marble 1200 x 2400 Setlock Wall Panel offers a striking marble-effect surface with no need for visible H-joining strips. This large-format panel measures 2.4m high by 1.2m wide, delivering seamless coverage while eliminating grout lines. The Setlock interlocking edges allow quick and precise joining, enhancing watertight performance and simplifying installation.

Crafted with a rigid 11 mm core—combining durable plywood and a premium laminate finish—this panel stands up to moisture, ideal for bathrooms, wet rooms, or splash-backs. The Onyx Marble décor features a light base with darker veining, offering a sophisticated, modern aesthetic that mimics natural stone without its weight or upkeep.

Maintenance is minimal: smooth surface cleaning with mild soap creates an easy, long-lasting finish. Because it’s a single large panel system, there are fewer seams to collect dirt or mould. Its robust construction and interlocking design deliver both visual elegance and practical performance, making it a smart upgrade to traditional tiling.
