Heritage Lux Cosmo

The Heritage Lux Cosmo blends modern Nordic craftsmanship with thermally modified materials to deliver an elegant and spacious outdoor sauna. Built with special-dried Thermo Pine and elevated by premium Thermo Aspen seating, it brings a refined wellness experience to any backyard or terrace—without sacrificing durability or design.

Heritage Lux Cosmo is a premium outdoor sauna for 2–3 users, handcrafted in Northern Europe with extended vertical clearance for a comfortable upright experience. Unlike most compact saunas, the Lux Cosmo’s elliptical cube design offers both vertical and horizontal space, allowing users to stand, stretch, and recline with ease. A tinted glass door and clean architectural lines complete its timeless, minimalist silhouette.

  • Extra Height, More Comfort: Taller than similar outdoor models, allowing users to stand upright and stretch fully inside the sauna.
  • Natural, Durable Materials: Body made from Thermo Pine; benches made from Thermo Aspen and engraved with the Heritage Sauna™ logo.
  • Thermally Modified Timber: Thermo-treated wood is approximately 5% denser than spruce, providing enhanced strength, tighter joinery, and improved acoustic properties—treated with only heat and steam, never chemicals.
  • Elegant Glass Design: Tinted, tempered glass door in a Thermo Pine frame gives the sauna a sleek, open-front appearance.
  • Two-Tier L-Shape Benching: Includes upper and lower bench levels in an L-shaped layout for flexible seating comfort.
  • Heater Guard: Thermowood panel protects users from direct contact with the heater.
  • Ventilation + Drainage: Built-in air vents and a floor drain help maintain a fresh, dry sauna environment.
  • Precision Fit Construction: Walls are 1.1 inches thick, with 1.65-inch staves, stainless steel tension bands, and painted Nordic spruce arch covers.
  • Floor Grate: Crafted from Nordic spruce and Thermowood for durability and water resistance.
