Infrared vs Traditional Sauna: Which Should You Buy?

The sauna aisle splits into two camps that barely speak to each other. Traditional sauna purists see infrared cabins as warm closets. Infrared fans see traditional saunas as needlessly scorching and inconvenient. Both have a point. The right choice depends less on which is 'better' and more on where you'll put it, how hot you like it, and whether the ritual matters as much as the result. Here's how the two compare on paper and in what owners report.

How the heat differs

A traditional sauna uses an electric or wood-fired stove to heat rocks, which heat the air around you. Throw water on the rocks and you get löyly, the burst of steam that defines the Finnish experience. An infrared sauna skips most of the air-heating step and uses panels that emit infrared light, which warms your body more directly. The result is a lower air temperature that many people find easier to stay in for longer. Neither is inherently superior. They simply produce different sensations, and people tend to have a strong preference once they've tried both.

• Traditional: hotter air, steam, faster and more intense sweat.
• Infrared: gentler air temperature, longer sessions, no steam.
• Traditional saunas typically need a longer preheat.
• Infrared cabins usually fit indoors more easily.

Our picks on each side

For infrared, the Clearlight Sanctuary 2 is where we'd start: two-person capacity, low-EMF full-spectrum heaters and woodwork that owners regularly praise. The Sunlighten mPulse Believe is the more gadget-forward choice, with app control and preset programs, and pricing that's quote-based and higher. On the traditional side, the Almost Heaven Pinnacle barrel sauna offers real high heat for four people at a price below either infrared cabin, provided you have the outdoor space and a free weekend for assembly.

The practical questions

Placement often decides the matter. If you live somewhere without a yard, an infrared cabin is the realistic option, and many two-person models are designed to sit in a spare room. If you have outdoor space and want the full ritual, a barrel sauna is hard to beat for the money. Check electrical requirements before ordering either type; heater sizes vary and some need a dedicated circuit installed by an electrician. Factor in delivery, foundation work and electrical costs, which can add thousands to the sticker price.

On wellness benefits, keep expectations measured. Research on regular sauna use, much of it from Finland on traditional saunas, has found associations with positive health markers, and many people simply report feeling relaxed and sleeping better. That research is observational and does not prove that any specific sauna will produce specific outcomes. Treat a sauna as a pleasant, restorative habit rather than a medical device, and talk to a doctor first if you have heart issues, are pregnant or take medications that affect heat tolerance.
