Choosing an infrared sauna comes down to four decisions: the type of heat, the size, the features you will actually use, and total cost including installation.

Far infrared heats gently at lower temperatures. Full spectrum adds near and mid wavelengths. Red light saunas add photobiomodulation alongside the heat.
