Leil Black Cube Premium Outdoor Sauna brings bold, compact design to smaller outdoor spaces, pairing the collection's signature dark finish with an upgraded interior for a more elevated session. The exterior features 40mm Thermowood walls, a black square shingle roof, and black tempered glass in both the front wall and door, with signature full-circle arches finished in black for a clean, architectural look. Inside, four seats are arranged on opposing two-level benches with bench skirts and back rests, creating a comfortable face-to-face layout that makes efficient use of the compact footprint. The Premium model adds a hexagon decorative feature wall, giving the interior a richer, more textured finish than the standard build. Integrated ventilation openings support stable airflow, while a black-painted baseframe and Nerostep grid flooring round out the durable construction. Compatible with electric heaters, Black Cube Premium delivers a striking, space-conscious sauna with a refined, upgraded finish.

Hexagon Decorative Wall Finish – An upgraded hexagon-patterned wall finish, included only in the Premium model, elevates the interior with a refined, textured backdrop you won't find on the standard Black Cube.

Face-to-Face Bench Layout – Two-level opposing benches with bench skirts and back rests seat four comfortably, creating a sociable layout suited to shared sessions in a compact footprint.

Compact Cube Design for Smaller Spaces – The Black Cube's clean, square-arched silhouette delivers the full sauna experience in a smaller footprint, fitting easily into patios and yards where space is limited.

Black Tempered Glass Throughout – An 8mm black tempered glass front wall paired with a matching tempered glass door brings a bold, cohesive dark aesthetic while letting in natural light.

Weather-Resistant Thermowood Construction – 40mm Thermowood walls and a black shingle roof combine durability with the collection's signature dark, architectural look.

Electric Heater Compatible – Built specifically for use with an electric heater, offering a straightforward, low-maintenance heating setup suited to compact outdoor saunas.

Practical Ventilation & Flooring – Integrated ventilation openings support stable airflow, while slip-resistant Nerostep plastic grid mats protect bare feet and simplify cleanup.
