    Understanding 3 Person Outdoor Sauna Prices and Cost

    Traditional vs. Infrared: Choosing Your Heater Technology

    Traditional saunas use a stone heater to create high heat and steam. They’re ideal for those who want an authentic, intense session. Infrared saunas run at lower temperatures, warming the body directly for a gentler experience and faster heat-up times. Both are effective—your preference for heat intensity usually decides it.

    Electrical and Foundation Requirements for Outdoor Saunas

    Most 3-person saunas need a dedicated electrical supply—typically 16A for infrared and higher for some traditional heaters. A solid, level foundation is essential: concrete pads, decking, or paving slabs all work well. Good airflow around the structure protects the timber and helps maintain performance.
