Materials - Made from a plastic-wood composite with a PE base. The surface has a hard texture that resists tearing. It is durable and can comfortably support the weight of an adult. Drainage and performance - Gaps between the flat segments and the hollow underside promote rapid water drainage and good airflow, helping the surface stay dry. - The PP underside is composed of many hollow triangles, providing some flexibility to maintain stability on grass, concrete, or other uneven surfaces. Size and comfort - 30 x 30 cm (11.81 x 11.81 inches). The mat is smooth and polished with no burrs, comfortable to stand on barefoot. Easy installation - A practical locking mechanism enables quick, tool-free installation. Even users with limited DIY skills can assemble and disassemble in minutes. Use scenarios - Home shower or bathroom floor to reduce slipping and improve drainage. - Outdoor showers or poolside areas on grass, concrete, or other uneven surfaces. - Gym, spa, locker rooms, or guest bathrooms where a stable, fast-drying mat is beneficial.
