Choosing between a traditional sauna and an infrared sauna is usually the first major decision in buying a home sauna. Most buyers do not know which one fits their space, budget, or routine until someone lays out the actual tradeoffs. We do not simply sell you a sauna. We help you understand saunas and confidently choose the right one, starting with this comparison.
The short answer, before the detail
| Traditional Sauna | Infrared Sauna | |
|---|---|---|
| How it heats you | Heats the air around you | Heats your body directly with radiant light |
| Typical temperature | 176°F to 212°F (Finnish Sauna Society) | 120°F to 140°F (typical range we see) |
| Typical cost | $5,000 to $8,000 for a home install | $2,000 to $6,000+, depending on tier |
| Heat-up time | Slower, needs the room and stones to warm up | Faster to start, no room air to heat |
| Best fit | Buyers who want the full ritual heat and steam | Buyers who want lower ambient heat and easier setup |
How Does a Traditional Sauna Heat You?
A traditional sauna heats the air in the room, and that hot air heats you. Humidity stays low, generally 10 to 20 percent in our experience, unless you pour water over the stones for steam.
The Finnish Sauna Society recommends a range of 176°F to 212°F for a full traditional session.1 That kind of heat carries measured benefits: regular use, four to seven sessions a week, has been associated with a 50 percent lower risk of fatal cardiovascular events compared to once a week,2 and with a 46 percent lower risk of high blood pressure in the same research population.3
Finland’s own sauna culture shows this heat style does not need reinventing. The country has an estimated 3 million saunas for a population of about 5.5 million people,4 a ratio built over generations of use.

How Does an Infrared Sauna Heat You?
An infrared sauna heats your body directly with radiant light, not the air around you. These heaters emit wavelengths that penetrate the skin and warm you from within, a mechanism Cleveland Clinic and Mayo Clinic both confirm independently.5 That direct mechanism is why the room itself stays at a much lower temperature than a traditional sauna. In our experience, most infrared sessions run 120°F to 140°F.
Research on near-infrared light links it to improved muscle recovery,6 though those specific studies used LED and laser devices rather than sauna heaters, so treat this as evidence for the underlying light mechanism rather than a sauna-specific clinical claim.
An infrared sauna is often the more approachable option for someone who finds a traditional sauna’s high heat overwhelming. The room air never has to heat up first, which usually means a shorter wait before your session.
Watch: Choosing an Infrared Sauna, and What to Check Before You Buy
What Does Each Type Cost?
A traditional home sauna typically runs $5,000 to $8,000 installed. Infrared saunas span a wider range, from about $2,000 for an entry-level unit to $6,000 or more for a premium build. These figures reflect what we see across real My Sauna Plus projects, not a single published market study.
| Tier | Traditional | Infrared |
|---|---|---|
| Typical range | $5,000 to $8,000 | $2,000 (entry) to $6,000+ (premium) |
| What drives the low end | Smaller room, simpler build | Limited-lifespan heaters, weaker heat output |
| What drives the high end | Larger room, premium wood, full install | Full-spectrum heaters, proper EMF shielding, smart features |
Both types add electrical cost beyond the unit itself. A dedicated 240-volt circuit, needed for most installs, runs about $700 on average, with a typical range of $250 to $1,100,7 and the wiring itself falls under NEC Article 424, Part VIII, the electrical code section governing fixed electric space-heating equipment,8 so this is not a do-it-yourself judgment call. Ongoing electricity use adds a smaller cost: the U.S. average residential price runs 16.48 cents per kilowatt-hour,9 and your total comes down mainly to your heater’s wattage and how often you run it.
In our experience, a full-spectrum infrared sauna rarely comes in under $2,000. A price that low usually means the unit does not use the technology the full-spectrum name implies.
Is There a Safety Consideration Specific to Infrared?
Yes, infrared heaters emit electromagnetic fields, or EMF, at close range, a recognized category of exposure governed by international safety guidelines.10 That is worth asking about before you buy. A quality infrared sauna is built with proper EMF shielding: the depth of that shielding is what separates an entry-level unit from a mid-range or premium one. Electric heating equipment in general carries well-documented safety stakes, with an estimated 1,700 fires and 80 deaths a year in the United States linked to space heaters,11 which is exactly why shielding and installation quality matter.
Which Type Fits Your Space and Routine?
The type that fits you depends on two things: the heat level you want, and the setup your home can support.
| Choose this if… | |
|---|---|
| Traditional | You want the full ritual: high heat, steam, and the deep sweat that comes with it. You have the space and electrical capacity for a larger install. |
| Infrared | You want a lower ambient temperature and a faster start. You are fitting the sauna into a smaller room. |
| Hybrid | You do not want to choose only one. A hybrid sauna combines both heating methods in a single unit, so you can run a traditional high-heat session one day and a lower-heat infrared session the next. |
Browse our hybrid saunas if that flexibility appeals to you.
