XPS board (Extruded Polystyrene board) for steam room construction

Oceanic XPS Steam Room Construction Board

The Oceanic XPS Construction Board is a professional-grade, high-density substrate engineered specifically for the rigors of high-humidity environments. Whether you are building a commercial spa or a home steam room, these boards provide the ultimate foundation for walls, floors, and custom-built features like benches and niches.

The Ultimate Wet-Area Foundation

Crafted from high-performance Extruded Polystyrene (XPS), our boards feature a dense, closed-cell structure that is 100% waterproof. Unlike traditional materials that can absorb moisture and degrade over time, Oceanic XPS resists water and vapor penetration, protecting your structure from rot, mold, and condensation damage.
