Mande MW12 ThermoWood Outdoor Sauna – 2-3 Person

The Mande MW12 is a 2-3 person outdoor sauna built from Scandinavian ThermoWood® and handcrafted in Lithuania. It is the most compact model in the MW series: about 4 feet deep, with a tempered glass front that keeps the small cabin light and open.

Mande MW12 at a glance

The MW12 seats two to three people on a footprint of 47.2" × 77.6", which suits patios, decks and smaller yards.

What is ThermoWood?

ThermoWood® is Scandinavian softwood that has been heat-treated without chemicals. The treatment lowers moisture absorption and improves dimensional stability and resistance to rot and insects. Left untreated, the exterior turns silver-grey over time; exterior oil every 2-3 years keeps the warm tone.

Features

• Tempered glass door and windows
• ThermoWood® benches with LED lighting underneath
• Built-in ventilation
• Bituminous roof tiles and exterior metal roof straps for rain and snow
• Doors, benches and back walls arrive pre-assembled

Site prep, power and assembly

You need a level, solid base: a concrete slab, a reinforced deck, a compacted paver base or compacted gravel with perimeter framing. The Harvia KIP 6.0 kW needs a dedicated 240 V circuit (typically a 30-40 A breaker, check the heater manual), installed by a licensed electrician. Two people assemble the MW12 in about 8 hours; no special carpentry tools are needed.

Delivery

The MW12 ships flat-packed in a wooden crate by freight, curbside with a liftgate, free in the lower 48. You move it to the base. A Harvia heater ordered with the sauna ships separately, directly from Harvia.

Questions about the MW12

Can the MW12 go indoors?

Yes, with an electric heater only and without the roof tiles, roof straps and rear siding, following local building and fire codes.

Is it insulated?

No separate insulation is used; the walls are solid ThermoWood® profiles built for traditional high-heat sauna use.

Do I need a heater?

Yes, every sauna needs one. Choose the Harvia KIP 6.0 kW above, the model the manufacturer recommends for the MW12, or bring your own compatible heater.
