How does delivery work?

Your sauna arrives as a DIY kit, securely packed on a large pallet and delivered via LTL freight. The driver will lower it to the ground at the curb (curbside delivery) and contact you in advance to schedule a convenient drop-off time. From there, you can move the individual panels to your build site — most pieces are easy to handle with two people.

Each shipment includes tracking updates and protective packaging to ensure a smooth delivery. At the driver’s discretion, your sauna may be placed inside a nearby garage. Most saunas can be fully assembled by two people in less than a day, and our team is always available to assist if you have any questions.

What are the electrical requirements?

Leil saunas require a 220–240V hardwired connection with a dedicated breaker. Dedicated 120V is also required for accessories such as lighting and controls.  We recommend confirming the exact amperage and wire size with your electrician based on the heater model.

How is the sauna built?

Leil Black Cube Saunas feature a durable thermo-pine construction, paired with thermo-alder benches that offer smooth, natural comfort and excellent heat resistance.

What are the dimensions?
  • Outer Dimensions (W × D × H): 85.8" × 65.4" × 87.4" (2.18 × 1.66 × 2.22 m)
  • Inner Dimensions (W × D × H): 78.7" × 54.3" × 82.7" (2.00 × 1.38 × 2.10 m)

What is the warranty?

Leil Saunas come with a two-year warranty that covers defects in materials and manufacturing, as well as damage occurring before transportation. The warranty does not apply to natural wood variations such as changes in color, cracks, or knots, nor does it cover normal wear and tear, incorrect assembly or installation, force majeure events like natural disasters or wars, or unauthorized modifications.

Description

Leil Saunas Black Cube Premium 4-5 Person Outdoor Sauna Kit

Modern Design | Outdoor Kit | Thermowood & Alder Finish

Minimalist Design. Maximum Presence.

Bold. Sophisticated. Unapologetically modern. The Black Cube Premium Sauna is more than a wellness space — it’s a sculptural statement for your backyard. With its sleek all-black Thermowood exterior, crisp lines, and smoked tempered glass, this sauna embodies contemporary luxury without compromise.

Designed for outdoor spaces where form matters as much as function, the Black Cube fits beautifully into compact yards and patios, while comfortably seating up to four adults inside. The interior features natural wood finishes, layered alder benches, and dimmable LED lighting, creating a soothing environment that’s as calming to the eyes as it is to the body.

Build It. Enjoy It. Make It Yours.

This sauna kit is designed for self-assembly — making premium wellness more affordable without sacrificing quality. With detailed instructions included, you or your builder can have it up and running in a matter of days. Every component is engineered to fit seamlessly together for a clean, professional finish.
