The Leil Saunas Black Cube Outdoor Sauna redefines outdoor wellness with a bold, modern design and unmatched functionality. Combining Nordic craftsmanship with thoughtful details, the Black Cube stands out for its comfort-enhancing layout, durable materials, and premium aesthetic. From its sleek black-tinted glass to its spacious L-shaped benches and superior ventilation system, this cube-style sauna is engineered to elevate your daily wellness ritual. Whether nestled into your backyard or set atop a scenic terrace, the Black Cube offers an immersive retreat with every session.

 

Note: Only the legs (which the sauna stands on), the side arches at the front and back, and the moldings around the door and windows are pre-painted black. The remaining exterior surfaces are left unpainted, with black paint provided for final finishing on site.

  • Made in Estonia: Expertly crafted using Nordic techniques and premium ThermoWood® materials.
  • Modern Cube Design with Shingled Roof: A refined outdoor sauna featuring a durable shingle roof finish that complements its contemporary aesthetic.
  • L-Shaped Bench Layout (Upper & Lower): More ergonomic and social than standard layouts, offering flexible seating positions and better space utilization.
  • Wider Bench Width (≈ 23.6 in): Extra-wide 23.6" benches allow full reclining, providing superior relaxation compared to standard 17.7" benches.
  • Concealed Bench Skirt: Included skirt hides under-bench space, giving the sauna a clean, seamless interior appearance.
  • Private Black-Tinted Glass: Tempered privacy glass on the front wall enhances both visual appeal and seclusion during your sauna sessions.
  • Spacious Interior — 10% Larger Than Most Cube Saunas: Offers a noticeably more open and breathable sauna experience for multiple users.
  • Optimized Heater Placement: Side-mounted heater maximizes front views from inside the sauna, creating a sense of depth and openness.
  • Thicker Thermo-Pine Back Wall: Roughly 43% thicker than industry standard, offering better insulation, strength, and sound dampening.
  • Optional Half-Panoramic Side Window: For those who prefer more natural light and scenic views, an upgraded window panel is available.
  • Advanced Ventilation System: Fresh air intake under the heater and exhaust behind the benches at foot level ensures consistent airflow and oxygen levels — while keeping your feet warm.
  • Nerostep Anti-Slip Floor Mat: Included non-slip mat enhances safety and underfoot comfort in wet or humid conditions.
  • Preinstalled Metal Roof Gutters: Functional and stylish gutters direct water runoff, protecting the structure from long-term weather damage.
  • Exterior & Interior Protection Kit Included: Comes with factory-finished arches, feet, door, and window frames, plus cans of exterior paint, interior floor varnish, and joint-sealing lacquer for long-term moisture resistance.
