Mande MW20 ThermoWood Outdoor Traditional Sauna, Electric or Wood-Burning Heater

The Mande MW20 is an outdoor sauna built from ThermoWood, a thermally modified timber. It is a strong fit for a backyard, garden or cabin site where you want a dedicated sauna building.

Choose how it heats: the standard configuration, a Harvia Kip 8.0 kW electric heater with either a built-in or WiFi controller, or a Harvia M3 wood-burning stove with a full chimney set. Use our heater size calculator to sanity-check heater sizing, or compare more outdoor saunas.

An outdoor sauna gives you a dedicated retreat a few steps from the house. Cooling off in fresh air between rounds is part of the ritual, and keeping the heat and humidity outside means nothing to manage inside your living space.

A traditional sauna is all about the löyly: once the stones are hot, a ladle of water sends a soft wave of steam through the room. Keep it dry for a gentler heat or add water for a more intense round, and take cool-down breaks between rounds, outside or under a cool shower. The upper bench sits in the hottest air, so move down when you want it milder.

Before you buy

• Prepare a flat, level base that drains well before delivery.
• Electric heater options need a suitable dedicated circuit; have a licensed electrician plan and connect it.
• For the wood-burning option, check local rules and clearances for the stove and chimney.
• Confirm what the Standard option includes before ordering, and review the photos for size and layout.

Care

Brush off leaves and snow, keep the base clear and dry, and air the cabin out after each session.
