MW20: The Ultimate Outdoor Sauna for Spacious Luxury

Designed for 5 – 6 people, the MW20 is the largest sauna in the Mande Spa USA collection – crafted to deliver maximum comfort and authentic European  wellness in your own backyard. Made in Lithuania, this premium sauna features ThermoWood® construction for superior durability, moisture resistance, and dimensional stability. MW20 isn’t just a sauna – it’s a retreat built to last. Experience European luxury, tradition, and relaxation with every session.

This sauna can also be installed indoors, provided you have a properly dedicated space with proper ventilation and suitable flooring. For indoor installation, several exterior components—such as the roof shingles, metal bands, and rear exterior siding—can be omitted during assembly, as they are intended primarily for outdoor weather protection. The core structure and premium European craftsmanship remain unchanged.

For indoor use, the sauna must be operated with an electric heater only, ensuring safe, clean, and code-compliant performance inside your home.
