Traditional Steam Sauna\u003c\/h2\u003e\n\u003cp\u003eThe Finnmark FD-5 Trinity XL is the flagship of the Trinity lineup, a 4' × 6' Infra-Steam cabin engineered to deliver three distinct heat therapies in a single, larger structure. Combine traditional Finnish steam from the Harvia KIP heater, full spectrum infrared, and gentle wood-heat sessions, all controlled from one app, all built into one premium thermal wood cabin. The XL footprint gives 3 people genuine room to spread out without crowding.\u003c\/p\u003e\n\u003ch4\u003eThree therapies, one cabin\u003c\/h4\u003e\n\u003cp\u003eMost home saunas force you to pick one heat type. The FD-5 lets you switch between full spectrum infrared (near, mid, far) and traditional Harvia steam in the same session, or combine them for the full Trinity experience. Infrared penetrates deep into muscle and joint tissue. Steam opens airways and pulls heat to the skin's surface. Together they deliver something neither does alone, and the cabin handles both without compromise.\u003c\/p\u003e\n\u003ch4\u003ePremium thermal wood, engineered for steam\u003c\/h4\u003e\n\u003cp\u003eThe cabin is built from premium thermal wood, a heat-treated softwood that resists moisture and won't warp under repeated heat-and-humidity cycles. Thermal modification removes resin from the wood, keeping the interior clean and inert at peak temperature. Critically for a steam-capable sauna, every joint and panel is engineered to handle the moisture loads that destroy traditional infrared cabins.\u003c\/p\u003e\n\u003ch4\u003eHarvia KIP heater plus full spectrum panels\u003c\/h4\u003e\n\u003cp\u003eThe traditional steam side runs on a Harvia KIP electric heater with sauna stones, the gold standard for residential Finnish-style löyly. The infrared side uses Finnmark's full spectrum heater panels with low-EMF technology. Both systems are wired to the V2 Wi-Fi controller, so you can start any session from your phone, schedule programs, and adjust temperature without leaving the bench.\u003c\/p\u003e\n\u003ch4\u003eCertified, documented, and ready out of the box\u003c\/h4\u003e\n\u003cp\u003eThe FD-5 ships with full UL listing on heating elements, ETL certification on the complete sauna system, and third-party EMF test logs you can review yourself. Finnmark publishes the documentation rather than just claiming the certifications, so you see the actual numbers, not just marketing language.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- HOOK SUMMARY --\u003e\n\u003cdiv class=\"sl-hook\"\u003eThe XL flagship of Finnmark's Trinity line, a 4' × 6' Infra-Steam cabin combining full spectrum infrared with a Harvia KIP traditional steam heater.
