Create a shared wellness retreat at home with the Medical 4 Full Spectrum Infrared Sauna, part of the Medical Sauna Series developed in collaboration with doctors. Designed for two, this sauna combines full spectrum infrared heat with thoughtful engineering to support circulation, muscle recovery, relaxation, and deeper, more restorative sleep.

The Medical 4 uses a Rapid Internal Heating System to bring the cabin up to temperature quickly, so you spend more of your session benefiting from the heat instead of waiting for the sauna to warm up. Full body infrared coverage, an insulated airflow design, and Medical Sauna’s 3D Heat Therapy work together to deliver even, penetrating warmth that supports detoxification, flexibility, and everyday comfort.
