Leil Round Cube Rc Mini - 4-5 Person Outdoor Prefab Sauna

The Leil Round Cube Rc Mini is a 4-5 Person outdoor prefab sauna kit engineered in Estonia. Delivered flat-packed for on-site assembly, with a base MAP of $12,145 - configure your heater, lighting, and (Patio S Plus/L Plus only) terrace-board extension to complete the build.

Introducing our Mini Cube model, the "Cube" Outdoor prefab sauna. Boasting an impressive size-changing area, this sauna is ideal for those seeking a rejuvenating experience after an intense session. The sauna area features a slightly tinted bronze glass wall, adding a touch of elegance to the overall design.

Outdoor prefab saunas have become increasingly popular in North America due to their ease of assembly, using prefabricated parts that provide a more traditional sauna look and feel. Our Cube Outdoor prefab saunas are crafted from thermally modified spruce, a weather-resistant wood that has undergone a process of heat and steam treatment to enhance its durability, resistance to decay, and dimensional stability. The use of this high-quality wood material adds to the overall longevity of the sauna and enhances its aesthetic appeal.

This particular Cube model includes top and bottom Alder benches, slightly shaped in an "L" configuration. You have the option to choose your preferred HUUM electric sauna heater, such as the floor-standing HIVE MINI, or a HUUM heater with Wi-Fi control for remote sauna operation via the HUUM app.

About Leil Saunas - Estonian Engineering

Leil Saunas is an Estonian manufacturer designing prefab saunas at the intersection of Nordic material tradition and modern architecture. Every model is built on a single controlled manufacturing campus in Tartu county, Estonia, where thermally-modified timber, refined glazing, and integrated hardware are assembled into modular kits ready for the toughest US climates.

The word Leil refers to the steam generated when water is poured onto hot sauna stones - in Estonian culture, it signifies "breath" or "spirit." That philosophy shapes every choice: high-humidity sessions, balanced Soft Heat (a controlled temperature-to-humidity ratio that lets you stay in longer without the sting of dry heat), and materials engineered to feel as good in year 10 as day one.

What Makes a Leil Sauna Different

1.57" thick ThermoWood® - heat-treated timber with all resins and moisture driven out. Superior insulation, natural resistance to rot and insects, and long-term dimensional stability against warping.
Cool-to-touch Aspen & Alder benches - low-thermal-conductivity woods that stay comfortable to sit on at 190-200°F.
Panoramic tempered glass - clear or bronze-tinted 8mm glass fronts flood the interior with natural light while maintaining thermal efficiency.
Precision triple ventilation - strategically placed intake, exhaust, and drying vents keep oxygen levels high and heat evenly distributed floor to ceiling.
Weather-ready fortification - EPDM-sealed roofs or high-grade shingles, integrated drainage, and black-treated moldings for year-round outdoor durability.
Modular assembly - pre-fabricated panels align cleanly; a two-person team can complete assembly in a weekend on smaller models.

Frequently Asked Questions

What is the advantage of ThermoWood®?

ThermoWood® is heat-treated at 400+°F to drive out resins and moisture. The result is a timber that resists warping, rot, and insects while providing better insulation than cedar or hemlock. It's what gives a Leil sauna its long service life outdoors.

Why does Leil use Thermo-Alder and Thermo-Aspen for the benches?

These species have very low thermal conductivity - they stay smooth and cool to the touch even when the ambient air hits 190-200°F. You won't feel the "sting" that resinous cedar can produce at high heat.

Is a heater included?

No. Leil ships as a cabin kit. Choose your heater bundle from the Heater Package dropdown - we offer complete packages from Harvia, Homecraft, and HUUM, or select "Bring Your Own Heater" if you're sourcing separately.

What kind of foundation does the sauna need?

A level, non-shifting foundation - a concrete pad, gravel pad with pavers, or a reinforced deck rated for the sauna's weight. Prefab kits are heavy (1,000-1,800+ lbs depending on model). We can help you size the pad if you send us your site details.

For Leil Saunas, how long does assembly take?

Smaller Leil models can be assembled by two people in one long day. Larger models typically need a full weekend and a third person to lift the glass wall panels safely. Detailed illustrated instructions ship with the kit.

What's the warranty?

Leil manufacturer warranty: 24 months on the sauna structure and hardware, with limited multi-year coverage on the ThermoWood® cladding against structural rot. Heater warranties are provided separately by the heater manufacturer (Harvia, Homecraft, or HUUM).

Can I use this sauna year-round?

Yes. Every Leil outdoor model is built for all four seasons - EPDM/shingle roof, weather-treated exterior cladding, and drainage-friendly design.

What is "Soft Heat"?

Soft Heat refers to a balanced humidity-to-temperature ratio. Leil's ventilation and airflow engineering lets you stay in longer for deeper therapy without the "stinging" dry heat sensation of some budget cabins.
