Product Highlights
ThermoWood Construction — Built for Outdoor Longevity
ThermoWood is softwood heat-treated in a controlled high-temperature process without chemical additives. The thermal modification reduces the wood's equilibrium moisture content — it absorbs and releases moisture more slowly than untreated softwood, which is the failure mode that causes warping, cracking, and dimensional movement in outdoor saunas through repeated heat-cool and wet-dry cycles. ThermoWood also has enhanced resistance to decay and insects compared to untreated softwood, and its naturally darkened color weathers gracefully without staining or painting.
Larger Interior for Family and Group Use
The MW16 is the MW12 scaled up for larger groups — the same ThermoWood build, the same heater options, and the same large windows and LED lighting, with the interior volume to accommodate family use. If your primary use is solo or 1–2 person sessions, the MW12 is the appropriate choice; if you are outfitting a sauna for regular family or small-group use where bench space and interior volume per person matter, the MW16 is the correct model.
Choice of Harvia KIP Heater — 6kW or 8kW, Standard or WiFi
The MW16's larger interior volume makes the 8kW heater the more appropriate specification for most buyers — the larger the interior, the more heater output is needed to bring it to temperature efficiently and maintain a consistent temperature. The 6kW is viable if you prefer a slower, more gradual heat-up. The WiFi controller adds remote preheat and control via the Harvia app over a 2.4GHz network; the built-in controller is a manual interface on the heater unit.
Heater Configurations and Prices
Four configurations: 6kW with built-in controller at $7,699; 8kW with built-in controller at $8,150; 6kW with WiFi controller at $8,513; and 8kW with WiFi controller at $8,598. Select your configuration from the variant selector before adding to cart.
Large Windows and LED Lighting
Large windows maintain a visual connection to the surrounding outdoor space — the difference between an enclosed sauna room and one that feels integrated with its garden or patio setting. LED lighting covers evening use and low-light conditions without natural light.

Important Information
Select your variant — heater output (6kW or 8kW) and control type (built-in or WiFi) — before adding to cart. For the MW16's larger interior, the 8kW heater is generally the recommended configuration for efficient heat-up and sustained temperature.
Electrical: the Harvia KIP requires a dedicated 240V outdoor-rated circuit installed by a licensed electrician. Confirm the amperage requirements for your chosen output before ordering. WiFi models require a 2.4GHz WiFi network within range of the installation site.
Freight delivery: at 376 lbs, this sauna ships freight. A responsible adult must be present at delivery to receive and assist with placement. Confirm driveway and gate access before ordering.
A level, solid foundation surface is required; site preparation is not included. Assembly is required on site; detailed instructions are included and basic tools are required. A permanent outdoor structure with an electrical connection may require a building permit — verify before ordering.

Frequently Asked Questions
What is the difference between the MW12 and MW16?
The MW16 has a larger interior volume than the MW12 — it is designed for family and group use, where the MW12 is better suited to solo and small-group (1–3 person) sessions. Both use the same ThermoWood construction, large windows, LED lighting, ergonomic benches, and Harvia KIP heater options.
Should I choose the 6kW or 8kW heater for the MW16?
For the MW16's larger interior, the 8kW heater is generally recommended — it brings the larger volume to temperature faster and maintains a more consistent temperature. The 6kW is viable but will take longer to heat the larger interior. If budget is your primary driver, 6kW is workable; if performance is the priority, choose 8kW.
What is ThermoWood?
ThermoWood is softwood heat-treated in a controlled high-temperature process without chemical additives. The treatment reduces moisture absorption, improving resistance to warping, cracking, decay, and insects compared to untreated softwood — a practical specification for outdoor sauna construction, where the structure cycles repeatedly between high heat and ambient outdoor conditions.
Does the sauna include a heater?
Yes — a Harvia KIP heater is included in all four variants. Select your preferred output (6kW or 8kW) and control type (built-in or WiFi) from the variant selector. Lava rocks are included with all configurations.
The Mande MW16 is the larger ThermoWood outdoor sauna — built for family and group use, with the same durable construction and Harvia KIP heater options as the MW12 at a scale that accommodates more people, starting at $7,699.
