The Heritage Sauna® Lux Cosmo is a 2–3 person outdoor sauna built from special-dried Thermo Pine with Thermo Aspen benching. Its elliptical cube design provides generous height and width, so you can stand, stretch or recline comfortably. The 1.1" walls with 1.65" staves are secured with stainless steel tension bands and set on a Nordic spruce cradle base, with Nordic spruce flooring adding long-term stability. The pre-engineered kit is designed for a one-day, two-person assembly.
Inside, two-tier L-shaped benches offer upper and lower seating for sitting upright or reclining. A tinted tempered glass door framed in Thermo Pine brings in natural light, while a Thermowood heater guard, built-in air vents and a floor drain help keep the space safe and dry. Every Lux Cosmo includes black shingles for the roof, along with a liter each of Black Saunasupi interior stain and Heather exterior stain. The stains are not pre-applied, so you can finish the sauna in bold black or leave the wood natural. The sauna pairs with an electric heater, sold separately.
