Dry sauna directory
Dry saunas use hot, dry air — often wood-lined rooms heated by electric stoves in gyms.
This guide covers how they feel, typical temperatures, and how they compare to steam and infrared. Use it to know what to check before you join a club.
What it is
A dry sauna is a heated room with low humidity, often wood-lined, where the air itself carries the heat. Gyms typically call these Finnish-style, traditional, or simply “dry” saunas.
On this site, listings use Dry Sauna. Elsewhere, a bare “sauna” label can mean dry heat, steam, or infrared, so check the type when you can. Stoves may run on wood, electricity, or gas, but electric heaters are what you will usually find in gyms and urban clubs.
How it feels / typical temperatures
Expect hot, dry air and heavy sweating, without the thick humidity of a steam room. Sessions are usually short, as people often sit, cool down, and return. Gym temperatures vary and are often not posted.
For comfort, spa-style settings often run around 158–176°F (70–80°C). Traditional dry saunas more broadly sit in the 158–194°F (70–90°C) band. Hotter sessions land toward the top of that range, around 194°F (90°C) or slightly above.
Heat sources and stove types
Sauna stoves are generally continuous-heating or heat-storage. Continuous-heating stoves have a smaller heat capacity, so they warm up faster on demand, while heat-storage stoves hold a large stone mass and take longer to heat.
Most modern gym, fitness center, and health club saunas use electric stoves. Heating elements warm a bed of rocks, and there is usually a thermostat and a timer. At clubs, staff often set the temperature, so members usually cannot change it.
How people control the heat
Bathers usually adjust a session three ways:
- Stay length: shorter or longer time in the room
- Bench height: higher benches are hotter; lower benches are cooler
- Water on the rocks: when allowed, ladling water onto the stove raises humidity so the heat feels stronger and you sweat more
The hottest air rises, so upper and lower benches can differ substantially. Sitting lower usually means cooler air and a milder session.
Many US gyms post signs not to put water on the rocks. Commercial heaters often use sealed elements or rock trays that are not built for repeated pouring. Hard or heavily chlorinated water can leave mineral scale or corrode trays, so clubs ban water to cut that maintenance. Older open-element heaters carried a shock risk if soaked, and some “no water” signs outlast the equipment they were written for. Follow the gym’s posted rules.
Safety and shared-space etiquette
Gyms usually post house rules for dry saunas. Thermostats are often set by staff; if a control is available, other bathers and club policy may matter before changing it. Stay clear of the stove and rocks, which can get hot enough to burn if touched, and water on the rocks can throw a sudden burst of steam. Towels, paper, and other combustibles near the heater are a fire risk. Contact lenses can dry out in the heat. Metal jewelry, glasses, and similar items heat up and can become uncomfortable or cause burns.
Dry vs steam vs infrared
- Dry sauna: hot air, low humidity. Heats mainly by heated air (convection and conduction) and warm room surfaces. Typical air about 158–194°F (70–90°C).
- Steam room: lower air temperature with high humidity.
- Infrared sauna: mainly radiant heat absorbed at the skin. Lower ambient air, often about 104–140°F (40–60°C).
What to look for at a gym
- The listing says Dry Sauna, not only “sauna”, steam, or infrared
- Access is included in your membership (or which tier / add-on applies)
- Hours match when you train. Locker-room saunas sometimes close earlier than the gym floor
- Locker-room rules (shared or gendered) if that matters to you
- Whether water on the rocks is allowed or prohibited
- Optional nearby cold plunge or shower if you want contrast

Pregnancy and health cautions
If you are pregnant or have health complications, lower temperatures or skipping the sauna is often advised. Check with a clinician.
A systematic review in the British Journal of Sports Medicine (Ravanelli et al.), discussed in this overview, looked at short heat exposures such as a dry sauna at 158°F (70°C) or a hot bath at 104°F (40°C) for up to about 20 minutes. In that synthesis, participants’ core temperature did not go above 102.2°F (39°C). Major obstetric guidelines, including ACOG-style advice, still commonly recommend avoiding saunas and hot tubs during pregnancy. This page is not medical advice.
