Infrared saunas have four main downsides: a lower maximum temperature than traditional saunas, a 110V or 220V power requirement depending on size, a cabin footprint that demands dedicated floor space, and heat that reaches the body directly rather than through steam — which disappoints buyers expecting a traditional wet-sauna feel.
The temperature ceiling is the most common source of dissatisfaction. Infrared saunas top out around 140°F, compared to 185–195°F in a Finnish-style dry sauna. Because infrared panels heat the body directly rather than the surrounding air, the sweat response is real — but the ambient heat feels milder to breathe. Buyers who want punishing high heat will find infrared saunas fall short. The 3–4 person models also require a 220V circuit, adding potential electrical setup cost if no existing outlet is nearby.
- Infrared sauna maximum operating temperature: approximately 140°F, versus 185–195°F for traditional Finnish saunas.
- Homsido 1- and 2-person infrared saunas run on standard 110V; the 3–4 person corner unit requires a 220V circuit.
- Minimum floor space for a 1-person infrared sauna: 33.5 x 33.5 inches exterior footprint, plus clearance.
- Infrared saunas produce no steam or humidity — buyers seeking a wet-sauna or steam-room experience will not get it from any infrared model.
- All infrared saunas produce some electromagnetic field output; carbon fiber panel designs reduce EMF but do not eliminate it entirely.
