The Black Cube Outdoor Home Sauna is a compact yet stylish retreat, accommodating up to 4 people in a design that blends modern elegance with traditional sauna craftsmanship. Built primarily from thermally treated pine, this sauna offers exceptional weather resistance, stability, and a rich warm tone that endures over time.

Product Details

Water Drain

This sauna includes a built-in water drain to ensure that any misplaced water is quickly removed from the cabin. The drain also simplifies maintenance and makes cleaning easier.

Optional Lighting

The sauna can also be equipped with interior lighting if desired. Two options are available under “Add Accessories” above the cart:

LED Set 2 – Backrest top or under the sauna bench
LED Set 4 – Backrest top and under the sauna bench

Optional Half-Panoramic Window

The Black Cube sauna can be customized with an optional half-panoramic window on the back wall, available in the dropdown menu. With the full-glass front already included, adding this window provides views on both sides, creating a bright and open atmosphere while still preserving the warmth and comfort of the sauna.

Ventilation

This cabin comes with a gravity-based ventilation system designed for efficient airflow. The intake vent is located just below the sauna heater, the recommended placement by most heater manufacturers. In total, there are 3–4 strategically placed vent openings to ensure proper circulation. The exhaust vents are positioned on the back wall, helping to maintain a steady flow of fresh air throughout the sauna.

Black Cube Construction

Black Cube is built with premium Thermo-Pine, a material celebrated for its durability and resistance to the elements, making it an excellent choice for year-round outdoor use. Its robust construction ensures long-lasting performance without sacrificing style.

This well-proportioned sauna comfortably accommodates up to 4 people, making it perfect for both social sauna sessions and personal retreats. Inside, the benches are crafted from smooth Alder wood, offering exceptional comfort and a warm, refined look. The layout provides an open, welcoming environment for true relaxation.

The Black Cube features a tempered glass door and windows, allowing natural light to brighten the interior while preserving a sense of privacy.

Unloading

Your Black Cube sauna will arrive on a crate/pallet weighing approximately 1,550 lbs with dimensions of 47″ x 85″ x 47″. The delivery driver will provide curbside service and lower the pallet to ground level at your property.

Electrical Requirements

You’ll need a 240V/1ph electrical line with a 30 amp breaker for the included sauna heater, along with a standard 120V line for the interior lighting.

Base

You need to make sure that you have a leveled and sturdy base for your sauna. You have to also consider where the water goes through the drain depending on the location of the sauna.
