The Heritage Lux Cosmo outdoor sauna combines modern Nordic craftsmanship with thermally modified materials to offer a refined 2–3 person wellness retreat. Constructed from special-dried Thermo Pine with Thermo Aspen benches, its elliptical cube design provides ample vertical and horizontal space, allowing users to stand, stretch, or recline comfortably. The tinted tempered glass door and clean architectural lines enhance the minimalist aesthetic while inviting natural light into the interior. Two-tier L-shaped benching, a Thermowood heater guard, and built-in ventilation and floor drainage ensure comfort, safety, and a dry, fresh environment. Precision-engineered walls, stainless steel tension bands, and durable Nordic spruce flooring deliver stability and long-term performance. Designed for easy 1-day, two-person assembly, the Lux Cosmo offers an elegant, durable, and functional backyard sauna experience that seamlessly blends style, ergonomic design, and year-round usability for personal or intimate group relaxation.

  • Spacious Elliptical Cube Design – Extra height and wide interior allow 2–3 users to stand, stretch, and recline comfortably, creating a versatile, ergonomic outdoor sauna experience that exceeds typical compact models.
  • Thermally Modified Nordic Timber – Constructed from Thermo Pine with Thermo Aspen benches, this wood is denser, stronger, and more durable than untreated timber, offering long-lasting stability, tighter joinery, and improved acoustic and thermal performance without chemicals.
  • Elegant Glass Door – Tinted, tempered glass framed in Thermo Pine enhances natural light, visibility, and minimalist aesthetics, providing a sleek, modern look while maintaining safety and durability.
  • Two-Tier L-Shaped Benching – Upper and lower benches in an ergonomic L-shape layout provide flexible seating options for reclining or upright positioning, maximizing comfort for multiple users.
  • Integrated Safety & Comfort Features – Thermowood heater guard, built-in ventilation, and floor drainage ensure a safe, dry, and hygienic environment, promoting consistent warmth and comfort during every sauna session.
  • Precision Engineering & Durable Construction – 1.1-inch walls with 1.65-inch staves, stainless steel tension bands, and Nordic spruce flooring provide structural stability, long-term durability, and straightforward 1-day assembly for two people.
