What Temperature Should a Sauna Be?

Sauna temperature by type, from maker listings

The pattern is clear. Traditional heaters in these listings top out around 195 F, which is about 90 C, while infrared cabins stop between 130 and 150 F. The hybrid cabin shows the gap in one product: the same room reaches 194 F with its stove and 149 F with its infrared panels. One infrared dome listing claims 194 F, an outlier we would ask the seller to explain.

Why infrared runs cooler and still feels hot

A traditional sauna heats the air, and the air heats you. An infrared sauna warms your skin directly, so the air can stay much cooler while you still sweat. That is why an infrared cabin at 140 F and a traditional room at 180 F are not as different to sit in as the numbers suggest. Our infrared vs traditional sauna guide explains the trade offs in more detail.

Humidity changes how hot a traditional room feels. Water poured on the stones raises humidity for a few minutes, and the same air temperature then feels much hotter. A gauge that reads both temperature and humidity, like the ones below, shows you what is happening.

Where you measure changes the number

Heat rises, so a thermometer near the ceiling reads higher than one at bench height, and the gap can be large in a traditional room. A built in display reads a sensor wherever the maker mounted it, which may be well above your head. For a reading that matches what you feel, hang a separate gauge near head height when seated, away from the stove or the panels, and give a mechanical gauge a few minutes to settle.

Do not put a regular household thermometer or a phone in a sauna. Look for a gauge rated to at least 230 F, and preferably 250 F, like the four here.

Sauna thermometers worth hanging

These are scored on the Chill Score, which weighs performance 35, build 25, value 25, safety certifications 10 where it applies and warranty 5. Gauges carry no safety listing, so all four score 0 for safety.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Setting the temperature in practice

• Start below the maximum. Makers state a top limit, not a target. One infrared listing recommends a comfort range of 115 to 130 F, below its 135 F maximum.
• Follow your manual on session length. One cabin listing here recommends 10 to 15 minutes, starting at low temperatures. Your manual and your doctor come before anything you read online.
• Allow warm up time. Infrared cabins usually warm in 10 to 15 minutes, while a traditional stove takes longer, and outdoor saunas take longer again in winter.
• Drink water before and after, and never use a sauna after alcohol.
• Respect the cutoff. Electric saunas have overheat protection. Kanlanth, for example, states a 230 F cutoff. If yours trips often, have it checked rather than resetting it again and again.

Common mistakes

• Comparing an infrared reading with a traditional sauna number and turning the infrared up to chase it.
• Trusting a ceiling sensor as the temperature at your head.
• Treating the colored zones on a dial as a safety rating. They are the seller’s markings.
• Staying in longer because the room feels cooler than expected.

Common questions

What is a normal temperature for a traditional sauna?

Traditional sauna listings with electric stoves state maximums of about 194 to 195 F. Many people sit well below the maximum. Start lower and follow the manual for your heater.

What temperature should an infrared sauna be?

Infrared cabin listings state maximums of 130 to 150 F, and one recommends a comfort range of 115 to 130 F. Infrared warms you directly, so a lower air temperature is normal.

Is 200 F too hot for a sauna?

None of the electric heater listings we collected state a setting above 195 F. If a reading goes above your heater’s stated maximum, check where the thermometer is hung and whether the overheat protection is working.

Why does my sauna thermometer read differently from the control panel?

The panel sensor may be mounted high on the wall, where the air is hottest, while a separate gauge at head height reads lower. Mechanical gauges also need a few minutes to settle.

Does a portable sauna get as hot as a cabin?

Usually not. The portable tents we found state maximums of 115 to 140 F. See our portable infrared saunas roundup for details.
