Leil Black Cube Classic 4 Person Outdoor Sauna Kit
Leil Saunas Black Cube Classic 4–5 Person Outdoor Sauna Kit
Modern Design | Outdoor Kit | Thermowood & Alder Finish
Minimalist Design. Maximum Presence.
Bold, sophisticated, and unapologetically modern, the Black Cube Premium Sauna is more than a wellness space — it is a sculptural statement for your backyard. Featuring a sleek all-black Thermowood exterior, clean architectural lines, and smoked tempered glass, this sauna represents contemporary outdoor luxury without compromise.
Designed specifically for outdoor environments where both form and function matter, the Black Cube integrates seamlessly into compact yards and patios. It comfortably seats up to four adults, making it ideal for shared relaxation.
Inside, natural wood finishes, layered alder benches, and dimmable LED lighting create a calm, immersive atmosphere — soothing to both the body and the eye.
Build It. Enjoy It. Make It Yours.
This sauna is delivered as a self-assembly kit, making premium wellness more accessible without reducing quality. With detailed instructions included, installation can be completed in just a few days by you or a professional builder.
Every component is engineered for precise alignment, ensuring a clean, seamless, and professional finish once assembled.
Crafted for Comfort. Designed to Impress.

Thermowood exterior and roof for durability and excellent insulation
2-level alder benches designed for sitting or reclining comfort
Tempered black glass windows and door for a private, atmospheric interior
