Infrared vs. Traditional Sauna: Which Should You Buy?

Short answer: a traditional sauna heats the air around you to 150 to 195 degrees Fahrenheit with an electric or wood-fired stove, and an infrared sauna uses panels to warm your body directly at a milder 100 to 140 degrees. Traditional needs a dedicated circuit and real outdoor construction. Infrared is a plug-in, mostly-indoor product. For a backyard, that difference decides it before you even get to the health claims.

Owner's Insights, Up Front

I will tell you plainly: I carry traditional outdoor saunas, not infrared. So take the comparison below for what it is, an honest answer to the question people search, written by someone who sells one side of it.

Here is why I made that call. Infrared is built as an indoor cabinet. It is not designed to sit through a Midwest winter, and almost everyone typing "outdoor sauna" or "home sauna" into Google is picturing wood, glass, and a Harvia heater, not a plywood box with panels. If you specifically want infrared for an indoor room, a gym, or a basement, there are dedicated infrared brands for that and this post will still tell you what to expect.

Infrared vs. Traditional Sauna: Quick Feature Comparison

Feature	Traditional sauna	Infrared sauna
How it heats	Stove heats the air and rocks; you can ladle water for steam	Panels emit infrared light that warms your body directly
Air temperature	150 to 195°F	100 to 140°F
Power needs	Dedicated 240V circuit for a 6 to 9 kW heater	Standard 120V household outlet
Heat-up time	30 to 45 minutes from cold	Little to no preheat; panels warm as you sit
Typical session	10 to 20 minutes at high heat	30 to 45 minutes at lower heat
Built for outdoors	Yes; cedar or thermowood shell rated for weather	Rarely; most models are indoor cabinets
Best researched benefit	Decades of Finnish cardiovascular research	Gentler heat tolerance; smaller, newer body of research

Those temperature ranges match what the North American Sauna Society and most sauna manufacturers publish. I am not a doctor, and this post is not health advice for either option.

What a Traditional Sauna Does Best

Heat, honestly, is the whole point. A traditional electric or wood-fired heater gets the room hot enough that ten minutes feels like a real session, and the option to ladle water over the rocks for a blast of steam is something no infrared panel can replicate.

It is also the only one of the two built to live outside. Every sauna I carry uses cedar or Finland pine construction rated for rain, snow, and freeze-thaw cycles, with a Harvia heater that is the industry standard in actual Finnish saunas, not a modified indoor unit. Prices run $4,999.95 to $11,995.95 depending on size. See the full lineup here.

What an Infrared Sauna Does Best

Lower heat and no preheat make infrared the easier one to tolerate if traditional sauna heat has always felt like too much. A standard wall outlet also means no electrician and no dedicated circuit, which matters if your only option is an indoor spare room with no 240V line nearby.

What it does not do is survive outdoors the way a real sauna shell does, and that is the main reason I do not stock it. If your plan is a backyard sauna, infrared is solving a problem you do not have.

Infrared vs. Traditional: Quick Decision Summary

Buy traditional if it is going outside, you want real heat and the option of steam, or you can get a dedicated circuit run.

Consider infrared if it is strictly an indoor install with no 240V access, you find high heat hard to tolerate, or portability matters more than authenticity.

For almost everyone reading this because they searched "outdoor sauna" or "home sauna," that means traditional. It is also the only one of the two I sell, and I would rather tell you that than pretend to be neutral.

FAQ

Is infrared or traditional sauna better for health?

Traditional sauna has by far the larger and longer-running body of research, mostly from Finland, tying regular use to cardiovascular benefits. Infrared research is newer and smaller in scale. Neither claim here is medical advice; talk to a doctor about your own situation.

Can an infrared sauna go outdoors?

Most infrared cabinets are built for indoor use and are not rated for the weather exposure an outdoor sauna needs. If you want something to actually live in your backyard year-round, a traditional cedar or thermowood sauna is the one built for it.

Does a traditional sauna need an electrician?

Yes. Every traditional outdoor sauna I carry uses a 6 to 9 kW Harvia heater that needs its own dedicated circuit. Infrared units plug into a standard outlet, which is the one real convenience advantage infrared has.

Why don't you sell infrared saunas?

Because almost nobody shopping for a backyard sauna wants an indoor cabinet, and I would rather sell one thing well than carry a product built for a different use case. If you need infrared specifically for an indoor room, look for a dedicated indoor-sauna brand.
