Leil Round Cube Relax 6-Person Outdoor Sauna Kit

Create a gathering place for heat, steam, and quiet conversation with the Leil Round Cube Relax Outdoor Sauna Kit. This backyard haven welcomes up to 6 bathers at a time, inspiring shared sessions of relaxation and recovery. The soft, natural Aspen U-bench offers a wide seating surface so you can sit back, lie down, or spread out.

This complete kit comes with all the hardware and materials needed to build a polished, professional sauna from base to roof. Between the optional Juniper rear wall and 3 glass tints, you can customize your Cube to meet your personal standards of taste and style.

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 Round Cube Sauna combines nature’s finest building materials with striking design to create a retreat tailored just for you.

  • 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 Benches - A wide 3-tier U-bench supports 6 bathers at a time, using a silky-smooth texture and a wide seating surface for exceptional comfort.
  • Full Shingle Surround - An elegant shingle surround adds intricacy to the sauna’s exterior and directs rain away from the entrance. No cold drips down the back during a rainy sauna session.
  • 20mm Dual-Pane Glass Windows - Dual-pane, tempered glass windows help contain the sauna’s heat and steam, offering an extra layer of insulation to put this cabin a step above the rest.
  • Nerostep Plastic Grid Mats - A standard safety feature for the Round 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 keep a steady flow of oxygen and help the sauna dry after every session. This helps the cabin stay fresh and inviting.
  • Optional LED Lighting - Add soft, dimmable lighting to your cabin interior for improved visibility and safety.
  • Optional Juniper Rear Wall - The optional Juniper Wood back wall creates an ambience like no other, offering an enchanting woodsy aroma and unique visual appeal.
Assembly & Installation

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

  • A stable, level foundation - A concrete foundation works best.
  • Heater Package - Pick up a complete heater kit to finish your build. This sauna can support electric sauna 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.
