Leil Black Cube Premium Outdoor Sauna Kit

Leil Black Cube Premium 4-Person Outdoor DIY Sauna Kit

Build a custom sanctuary of heat and steam with the Leil Black Cube Premium Outdoor Sauna Kit. Complete with everything necessary for a DIY construction, this kit includes: building materials, hardware, varnish, paint, and sealant.

The Premium’s primary material is durable ThermoWood pine, chosen for its rich color and incredible weather resistance. These properties not only provide effective interior heat management and style, but also help your sauna withstand mild-to-harsh climate conditions. While the interior of your sauna preserves the wood’s dark hue, the exterior is finished in a black paint to match the striking arched frame and tinted, full-tempered glass front.

The 2-tier alder and aspen benches use a double-I design that keeps up to 4 bathers facing each other at a time. These benches are equipped with bench skirts and backrests, adding comfort to the setup for top-tier relaxation. The interior is tied together with a decorative, hexagonal back wall for mesmerizing style and meditation.

Integrated vents use a gravity-based approach to air circulation, ensuring a consistent flow of oxygen to keep your sessions comfortable. This ventilation system also supports fast drying when the session is done, working with the built-in floor drain to prevent mold and rot.

This Sauna Kit is compatible with electric sauna heaters (not included) for convenient and modern session set ups.

ATTENTION: This kit does NOT include a heater, controller, stones, or lights. You can find these items in the Suitable Accessories menu above.
