{"product_id":"finnmark-fd-4-trinity-infrared-and-steam-sauna-combo-2-person","title":"Finnmark FD-4 Trinity Infrared and Steam Sauna Combo, 2 Person","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe Finnmark FD-4 Trinity brings three kinds of heat to one cabin built for two. Step in for full-spectrum infrared, add traditional heat from a Harvia sauna heater and stones, and switch on the red light panel, all from a single bench.\u003c\/p\u003e\n\u003cp\u003eThe cabin is finished in clear A-grade Canadian Western Red Cedar inside and a Thermal Plus Aspen exterior, with a tempered glass door and two-tier benching. It stands freestanding indoors and can be placed outdoors when paired with the fitted cover. Add the combination bench cushion, the outdoor cover, or both to match where and how you plan to use it.\u003c\/p\u003e\n\u003cp\u003ePer Finnmark Designs, the FD-4 Trinity pairs Spectrum Plus infrared panels with a Harvia Vega Compact 1.9 kW sauna heater and a box of Harvia AC3000 stones, so you can run infrared heat, traditional steam heat, or both. A V2 LCD touchscreen controller with Bluetooth manages temperature, timing, and the interior lighting. The infrared side runs on a dedicated 120V, 15-amp circuit through a NEMA 5-15P plug, and the Harvia sauna heater is hardwired on its own dedicated 120V circuit. Have a licensed electrician confirm both circuits before installation.\u003c\/p\u003e\n\u003cp\u003eWe confirm your exact shipping timeline within 1-2 business days of your order - or email us before you buy for the current lead time on this product.
