Leil Black Cube Premium 4-Person Outdoor Sauna Kit

Build a custom sanctuary of heat and steam with the Leil Black Cube Premium Outdoor Sauna Kit. This stylish retreat welcomes 4 bathers at a time, creating a communal space to reset and recharge. The perfect addition to post workout recoveries and daily wellness routines, a session in the Leil Black Cube Premium is permission to breathe deep and let the day go.

This kit comes with all the materials and hardware needed for construction. Add an optional LED light kit to complete your build, creating a warm ambient glow in every session.

Note: This kit does NOT include a sauna heater package or lights. You can find these items in the Suitable Sauna Heaters menu above.
Features & Materials

The Leil Black Cube Sauna pairs sharp modern style with timeless building materials for a cabin that looks as good as it performs.

  • 40mm ThermoWood Pine Walls - Rich in color and strong by nature, ThermoWood Pine walls cradle heat and steam for perfect sauna conditions all year long.
  • Natural Aspen & Alder Benches - A set of 2-tier benches hold up to 4 bathers at a time, using a silky-smooth texture for unmatched comfort. These benches come with bench skirts and backrests for extra support.
  • Striking Arched Frame - Built for the bold, the sauna’s arched frame draws attention with a smooth profile and deep black finish.
  • 8mm Full-Tempered Tinted Glass Front - The tempered glass front offers a full-length window to nature with a dark black tint that softens natural light and brings a touch of privacy.
  • Nerostep Plastic Grid Mats - A standard safety feature for the Black Cube series, a Nerostep plastic grid mat offers a clean and dry surface for extra traction and mobility.
  • Integrated Ventilation and Drainage - The built-in ventilation and drainage systems create a steady flow of oxygen and help the sauna dry after every session. This keeps the cabin fresh and inviting.
  • Hexagonal Rear Wall - A decorative rear wall inspires meditative relaxation, using a hexagonal pattern to add depth and character to the sauna interior.
  • Optional LED Lighting - Add soft, dimmable lighting to your cabin interior for improved visibility and safety.
Assembly & Installation

The Leil Black Cube Premium Sauna requires assembly and finishing. In addition to this kit, you will need:

  • A stable, level foundation - Driven piles or a concrete foundation work best.
  • Heater Package - Pick up a complete heater kit to finish your build. This sauna can support electric heaters (not included).
  • Certified Electrician - You will need a certified electrician to help with the wiring for the sauna heater, controller, lighting, and any other wired accessories.
  • Building Permits - Check with your local building department for any building permits and safety requirements needed before construction.
