Infrared vs. traditional home saunas: costs and specs compared

Last updated Oct 17, 2026. Figures come from our nightly price checks, as of the date shown in each section.

“Infrared or traditional?” is usually the first decision in buying a home sauna. It drives the price, where the sauna can go, what kind of electrical work you need, and what the specs on the listing mean.

This guide sticks to costs and specs. We don’t cover health effects, and we don’t repeat brands’ health claims. Figures come from our nightly check of 20 sauna stores on October 17, 2026.

The short version

“Median lowest price” means: for each model we take the lowest price across the stores that sell it, then take the middle value across all models of that type. “Middle half” is the range from the 25th to the 75th percentile.

These counts only include models where the store states the heat type. 392 of the 825 sauna models we track have it stated. The rest are often saunas sold as kits or shells, or listings that don’t say.

Why infrared saunas usually cost less

From the specs stores publish, the price difference mostly comes down to three things:

1. Size and build. Infrared saunas in our data are mostly indoor cabins: 179 of the 223 infrared and full-spectrum models are cabins, and the most common stated capacities are 2 and 3 people. Traditional saunas are more often outdoor buildings (76 of the 140 traditional models state outdoor use; 21 are barrels and 13 are cubes) that have to stand up to weather.
2. The heater. An infrared sauna’s heating panels are built into the walls. A traditional sauna needs a stove or electric heater with rocks, usually sized in kilowatts. Many traditional saunas list the heater as an option, which pushes the final price up.
3. Electrical. Of the infrared and full-spectrum models that state their voltage, 93 of 141 are 120V. Among traditional saunas that state it, only 2 of 97 are 120V. The rest are 240V or depend on the heater option.

You can see the electrical difference in the data. Models that state 120V had a median lowest price of $3,549 (112 models). Models that state 240V had a median of $8,500 (81 models). That isn’t because 240V costs more by itself. It’s that 240V heaters go with bigger, traditional saunas.

What “full-spectrum” means on a listing

“Full-spectrum” is a marketing label for infrared saunas that combine near, mid and far infrared emitters. In our data, full-spectrum models sit between standard infrared and traditional on price (median $5,997).

As a shopper, what matters is that it’s a different heater design, not a standard. Two “full-spectrum” saunas can use very different emitters. If you’re comparing them, look at:

• the type and number of emitters listed for each wall,
• the stated electrical requirement (120V vs 240V, and amps),
• the warranty on the heaters specifically, not just the cabinet.

We don’t rate infrared wavelengths or their effects. We just record what the store states.

Hybrid saunas

Hybrids combine a traditional heater and stones with infrared panels. They’re the most expensive group in our data (median $8,995), and there aren’t many (29 models with the heat type stated). Expect 240V wiring and a larger footprint than a typical infrared cabin.

Temperatures as stated

155 sauna models state a maximum temperature. Infrared models that state one almost all say 140°F. Full-spectrum models state 140°F to 170°F. Traditional models state 190°F or more (up to 230°F). The lower figure for infrared is how that design is specified, not a defect. It does mean the “max temp” number isn’t a quality score when you compare infrared and traditional saunas.

Wood and interior

Wood strongly tracks price (full details in our spec guide). The cheapest group in our data is Canadian hemlock (median $3,299 across 130 models), and many lower-priced indoor infrared cabins use it. Traditional outdoor saunas more often use cedar, spruce, aspen or thermally modified woods, which sit at higher price points.

Where it goes: indoor vs outdoor

• Indoor saunas (215 models stating it): median lowest price $4,999, middle half $2,899 to $7,991.
• Outdoor saunas (216 models): median $9,790, middle half $7,321 to $14,999.

Among models that state both location and heat type, indoor saunas are mostly infrared (113 infrared vs 29 traditional) and outdoor saunas are mostly traditional (76 traditional vs 10 infrared). If you want an outdoor infrared sauna, check that the brand says the model is rated for outdoor use. Some infrared brands require a cover or a roof for the warranty to apply outdoors.

Running costs

Running cost depends on the heater’s power draw, how long the sauna takes to warm up, insulation, and your electricity rate. Stores publish heater power more often than total energy use, so a simple way to estimate is:

kW × hours used × your price per kWh

For example, a 6 kW heater running for one hour at a rate of $0.17/kWh uses 6 kWh, or about $1.02 (the rate here is just an example; use the rate on your power bill). Heaters cycle on and off once at temperature, so real use is usually less than the full-power figure, but the calculation gives you a ceiling. Infrared panels draw less power, so they usually cost less per session. Their total also depends on session length.

Questions to ask before you buy

• Is the heater included in the listed price? Which model, and how many kW (or how many panels)?
• What electrical service does it need: 120V plug-in, 240V, how many amps, and does it need a dedicated circuit?
• Indoor only, or rated for outdoor use? What does the warranty require outdoors?
• Does the warranty cover heaters and electronics separately from the wood cabinet, and for how long?
• What does delivery include: curbside, or brought inside? Is assembly included?

Bottom line

On price alone, standard infrared saunas are the cheapest way into a home sauna in our data, with traditional and hybrid saunas costing roughly two to three times as much at the median. But the categories differ in size, heating method, electrical needs and placement, so compare within the type you actually want.

Where these numbers come from

Nightly check of 20 sauna stores on October 17, 2026, covering 825 models from 1,002 listings. Heat type, voltage, wood, location and temperature come from the store’s own listing. When a store doesn’t state a spec, we leave it blank, so group counts are smaller than the total.
