Infrared saunas use different wavelengths of light to generate warmth, and each penetrates the body at a different depth. Near infrared wavelengths are shorter and interact closer to the skin's surface, while far infrared wavelengths are longer and are designed to support a deeper, more enveloping warmth. Full-spectrum models include all three wavelengths, giving you the flexibility to adjust your session to how you want to feel.

Most home infrared saunas require a clear, level area with access to a standard power outlet, and dimensions vary by the number of occupants the unit is designed for. A compact one-to-two-person cabin typically fits comfortably in a spare room, basement, or garage, while larger models benefit from a more dedicated space. We recommend measuring your intended area and comparing it against the product's listed dimensions before purchasing.

Requirements vary by model — smaller personal saunas often run on a standard 120V household outlet, while larger cabins may require a 240V dedicated circuit. Each product listing details the exact electrical requirements so you can confirm compatibility with your home setup before ordering. If you are unsure, consulting a qualified electrician prior to assembly is a practical step.
