Premium Recessed Shower Niches: Modern, Durable & 100% Waterproof Upgrade your shower with our premium recessed niches. The perfect combination of style, strength, and precision craftsmanship. Designed to provide sleek, built-in storage for your bathroom essentials, these niches keep your space clutter-free while adding a luxury finish. Our niches are machined on a state-of-the-art Valiani computerised cutter that uses a precision blade instead of a saw. This ensures size accuracy to within a single millimetre and produces smooth, perfectly finished edges, ready for tiling and easy installation. We use 12.5 mm thick Nass Boards as standard on all our niches, the market leader in waterproof boarding. Each board features a core of high-density extruded polystyrene (XPS) for excellent thermal insulation and compressive strength. Both sides are finished with a reinforced cementitious coating, giving a hard, tile-ready surface with added fire resistance. A fiberglass mesh is embedded within the coating to maximise mechanical strength and ensure a strong bond with tile adhesives. Every niche is assembled using BostikOB1 construction-strength sealer and adhesive, delivering unmatched durability and a watertight seal that lasts. Why choose us: Unrivalled Waterproofing: Nass Boards with XPS core, cement coating, and fiberglass mesh for ultimate strength and protection, coupled with OB1 for exceptional bonding strength and a lasting watertight seal.
