Questions Worth Answering
FAR infrared operates in the 7–14 micron wavelength range and is the most studied segment of the infrared spectrum for sauna use. Full-spectrum units add near and mid infrared, which operate at shallower depths and higher surface temperatures. The cabins in this collection are FAR infrared, which means lower cabin air temperature — typically 120–150°F — and a radiant heat experience that warms from the inside out rather than heating the surrounding air first.
Carbon heater panels produce electromagnetic fields as a byproduct of resistance heating, and EMF exposure is a reasonable thing to evaluate in a product you sit close to for 20–40 minutes at a time. Low-EMF panels are tested and built to limit field strength at occupant distance; the cabins in this collection use carbon heaters specified to low-EMF standards. Ask for test data in milligauss at body distance if a specific threshold matters to you.
The hemlock and spruce cabins in this collection are engineered primarily for indoor or covered outdoor placement — a garage, a basement, a sheltered deck, or a purpose-built outbuilding. Untreated hemlock performs well in stable indoor humidity but is not rated for fully exposed year-round outdoor conditions the way pressure-treated timber would be. If a fully outdoor build is the goal, the traditional cedar outdoor models in the Traditional Saunas collection are a more appropriate choice.
Infrared sauna cabins ship free on most orders within the Continental U.S., excluding Alaska and Hawaii. Freight shipments of this size typically arrive palletised via LTL carrier; assembly from flat-pack is handled by the customer using the supplied hardware. If the unit arrives damaged or does not meet expectations, our 30-Day Return Policy applies — review the policy page for the full terms and conditions before purchasing.
About Our Infrared Saunas
Far infrared saunas operate on a fundamentally different principle than traditional steam or convection saunas. Rather than raising ambient air temperature to transfer heat to the body, infrared panels emit radiant energy in the far infrared wavelength range, which the body absorbs directly. The result is a cabin that runs cooler in the air — typically between 120 and 150 degrees Fahrenheit — while still delivering substantial thermal load to the occupant. This makes extended sessions more manageable for people who find high-humidity or high-convection heat difficult to tolerate. The construction material matters: dense, low-resin softwoods like Canadian hemlock and spruce hold their dimensional stability under repeated heat cycling and do not off-gas the way engineered or treated timber can. Carbon fibre heating panels are the current standard for low-EMF performance and even heat distribution across the wall surface. Buyers should evaluate heater placement, panel wattage relative to cabin volume, EMF ratings at occupant distance, and the quality of the door seal and insulation before committing to a unit.
