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.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"highlight-item\"\u003e\n      \u003ch3\u003eLarger Interior for Family and Group Use\u003c\/h3\u003e\n      \u003cp\u003eThe 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.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"highlight-item\"\u003e\n      \u003ch3\u003eChoice of Harvia KIP Heater — 6kW or 8kW, Standard or WiFi\u003c\/h3\u003e\n      \u003cp\u003eThe 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.
