Patio Elegance Mande MW20 ThermoWood Outdoor Sauna

The Patio Elegance Mande MW20 ThermoWood Outdoor Sauna is the largest model in the MW Series, designed for homeowners who want a spacious outdoor sauna capable of comfortably accommodating five to six people. Whether you’re hosting family gatherings, enjoying wellness sessions with friends, or creating your own backyard retreat, the MW20 delivers an authentic European sauna experience with exceptional comfort and craftsmanship.

Handcrafted in Lithuania by skilled sauna artisans, every MW20 is built using sustainably sourced Scandinavian ThermoWood. Through a chemical-free thermal modification process, the wood becomes naturally resistant to moisture, rot, warping, cracking, and decay while maintaining excellent dimensional stability for year-round outdoor use.

The spacious interior features two levels of ThermoWood benches, warm LED under-bench lighting, tempered glass windows and door, and an integrated ventilation system that promotes consistent airflow and heat distribution. A durable bituminous shingle roof provides long-lasting protection against rain, snow, and UV exposure while complementing the sauna’s clean, contemporary design.

The MW20 arrives as a precision-cut flat-pack kit with detailed assembly instructions and assembles using standard tools. Heater options are available at the time of purchase, allowing you to customize your sauna experience with either an electric or traditional wood-burning heater.

Manufactured by Mande Wood in Lithuania and distributed in the United States through Mande Spa USA, the MW20 reflects generations of European sauna tradition combined with modern engineering and premium materials.

Patio Elegance is proud to offer this exceptional outdoor sauna backed by manufacturer warranty support and our commitment to outstanding customer service.

Note: Sauna heaters are optional and sold separately unless selected. All electric heater installations must be completed by a licensed electrician. Units ship via LTL freight with curbside delivery.
