4-Person Black Cube Classic Sauna

Black Cube Classic Sauna is the most compact model in the range, designed for tight outdoor spaces while still offering the proper sauna layout for up to four. Classic is intended for use with an electric heater only, making it a practical choice where simple installation and a minimal footprint are the priority.

Black Cube Outdoor Sauna Collection

Black Cube is our most compact outdoor sauna collection, defined by its bold dark finish and distinctive cube form with signature arches. Designed for smaller outdoor spaces without compromising on style, the series offers a configurable setup: depending on the model, you can choose different bench layouts, upgrade interior finishes, and add features such as LED lighting and rear glazing. The result is a compact sauna with a strong visual identity and the flexibility to tailor both the look and the session to your needs.

From the outside, Black Cube is defined by a clean, compact form and a dark architectural finish. The standard construction features 40 mm Thermowood walls, a square shingle roof, and black tempered glass in the front glazing and door. Signature full-circle arches on the front and rear walls are finished in black, while integrated ventilation openings support stable airflow and reliable outdoor performance. 

Inside, Black Cube features two-level benches with skirts and backrests. Depending on the model, it is available with different bench configurations, and selected versions include an optional decorative feature wall. Lighting can be specified with LED strips, and the rear wall can be configured with a half panoramic window to bring in natural light while keeping the layout simple and functional. 

Features

Standard Set Includes:

• Premium Roof Finish
  
  – The Black Cube features a high -quality shingle roof finish that provides excellent durability and a refined look.
  
  

• L-Shaped Upper Bench
  
  – Inside, both the upper and lower benches follow an L-shaped layout, offering more seating comfort and flexibility than typical straight-bench designs.
  
  

• Bench Skirt Included
  
  – A bench skirt conceals the space beneath the seating, giving the interior a more complete and premium appearance.
  
  
• Wider Benches for Reclining
  
  – The Black Cube’s bench width is 60 cm (≈ 23.6 in), compared to the more common 45 cm (≈ 17.7 in) width. This allows users to lie down comfortably during the sauna session.
  
  
• Private Black-Tinted Glass
  
  – The black tempered glass front ensures privacy from the outside while maintaining a sleek, modern aesthetic.
  
  
• More Spacious Design
  
  – The Black Cube is approximately around 10% larger internally, providing noticeably more room to relax.
  
  
• Optimized Heater Placement
  
  – The side-mounted heater opens up the front view from inside, creating a more spacious and scenic feeling.
  
  
• Thicker Back Wall
  
  – The back wall is made from 40 mm thermo-pine, roughly 43% thicker than the more typical 28 mm wall structure —improving both insulation and durability.
  
  
• Optional Half-Panoramic Window
  
  – For those who want extra light and visibility, the Black Cube offers a half-panoramic side window upgrade.
  
  
• Superior Ventilation System
  
  – An intake vent under the heater and exhaust vent behind the benches at foot level ensure efficient airflow, warmer feet, and a consistently fresh oxygen supply.
  
  
• Nerostep Floor Grid Mat Included
  
  – A non-slip Nerostep mat is included as standard, improving safety and comfort underfoot.
  
  
• Metal Roof Gutters
  
  – The roof is finished with metal rain gutters, adding a refined, functional detail that helps direct water runoff and enhances durability.
  
  

• Exterior Paint and Interior Protection Kit Included
  
  - The Black Cube comes with a complete finishing set: the feet, side arches, and door & window frame are pre-colored at the factory, while exterior paint for the sauna is supplied in a can for on-site application after assembly. In addition, the set includes interior floor varnish and joint-sealing lacquer to ensure long -term water resistance and durability. This guarantees that every unit can be finished to a professional, weatherproof standard.
