Portable Steam Sauna vs Infrared Sauna: Which Is Better?
For home use, a portable steam sauna is generally better if you want a traditional, high-humidity heat experience at a lower price, while an infrared sauna is better if you prefer dry, lower-temperature heat that may feel more tolerable for longer sessions. The right choice depends on your space, budget, and how your body responds to different types of heat. Below we break down how each works, what they cost to run, and which one fits common home scenarios.
How Each Type Works
Portable steam sauna: This is a small tent-like enclosure with a chair inside and a steam generator on the floor or side. You sit inside with your head out through a collar opening. The generator boils water to produce steam, which fills the tent. The air becomes very humid, often reaching near 100% relative humidity, and the temperature typically stays between 100–120°F (38–49°C). Because the humidity is so high, you sweat heavily even at moderate temperatures.
Infrared sauna: Instead of heating the air, infrared saunas use infrared heaters that emit radiant heat absorbed directly by your skin and body. The air temperature is lower, usually 120–150°F (49–65°C), and the humidity is low. You sit in a small cabin made of wood or other materials. The heat feels less oppressive than steam, and many people find they can stay in for 30–45 minutes without discomfort.
Space and Setup
Portable steam saunas are collapsible and store in a small bag. They need about 3×3 feet of floor space when set up. You also need a place to plug in the generator and a source of water to fill it. They are ideal for apartments or for people who want to use the sauna occasionally and put it away.
Infrared saunas come in two forms: portable (tent-style with carbon or ceramic heaters) and permanent (wooden cabins). Portable infrared tents are similar in footprint to steam tents but require no water. Permanent infrared cabins are larger, typically 4×4 feet or more, and are not easily moved. If you plan to use a sauna daily, a permanent cabin is more convenient, but it requires dedicated floor space.
Health Effects and Comfort
Both types raise your core body temperature and induce sweating, which can promote relaxation and temporary relief from muscle tension. The key difference is humidity.
- Steam sauna: The high humidity makes you feel hotter than the air temperature suggests. It can feel suffocating for some people, especially those with respiratory issues, but the moist air can also feel soothing for a dry cough or sinus congestion.
- Infrared sauna: The dry heat is easier to breathe and feels gentler on the skin. Some users report that infrared heat penetrates deeper into muscles, but there is no scientific consensus on this. The lower air temperature means you can stay in longer without the claustrophobic feeling of steam.
If you have cardiovascular conditions, consult a doctor before using either. The heat stress on the body is real, and both types can cause dehydration if you don’t drink water before and after.
Cost and Maintenance
Portable steam saunas are cheaper to buy, often under $200. The ongoing costs include electricity (as calculated above) and the water you use. You also need to clean the generator periodically to prevent mineral buildup, and the tent interior can get damp and must be dried to avoid mold.
Infrared saunas are more expensive. Portable infrared tents range from $200–$400, while permanent wooden cabins can cost $1,000–$3,000 or more. They use more electricity because the heaters are higher wattage (typically 1200–1800 W), but they still cost only a few cents per session. Maintenance is minimal: wipe down the interior and replace the heaters if they fail (which is rare).
Which One Should You Choose?
Choose a portable steam sauna if:
- You have limited space and want to store it away.
- You prefer the traditional, high-humidity sauna experience.
- Your budget is under $200.
- You don’t mind the hassle of filling water and drying the tent.
Choose an infrared sauna if:
- You want a dry, lower-temperature heat that feels easier to tolerate.
- You plan to use it frequently and want a more permanent setup.
- You are willing to spend more upfront for a sturdier product.
- You have respiratory sensitivity to high humidity.
Common Problems and Misconceptions
Myth: Infrared saunas “detoxify” your body better than steam. Both make you sweat, and sweat does contain trace amounts of toxins, but your liver and kidneys are the primary detox organs. Neither type is medically proven to remove more toxins than the other.
Problem: Steam tents leak. Many users report steam escaping around the collar. This is normal and not a defect; it helps keep your head cool. Just place a towel around the collar to reduce drafts.
Problem: Infrared heaters stop working. If one heater fails, the sauna still works but heats unevenly. Replacement heaters are available from the manufacturer, but they are not universal.
Misconception: Higher temperature means a better workout. The body’s response to heat depends on humidity, duration, and your hydration level. A 120°F steam sauna can feel more intense than a 150°F infrared sauna because of the humidity.
Frequently Asked Questions
Can I use a portable steam sauna indoors? Yes, but place it on a waterproof mat or in a bathroom. The steam can damage wood floors over time. Always leave the tent open to dry after use.
How long should I stay in each type? Start with 10–15 minutes and build up to 30 minutes maximum. If you feel dizzy, lightheaded, or nauseous, exit immediately. Never sleep in a sauna.
Do infrared saunas use more electricity than steam? Generally yes, because the heaters are higher wattage. But the difference is small in absolute terms—a typical session costs under 15 cents for either type.
Can I use essential oils in a steam sauna? Some portable steam generators have a small tray for oils, but check the manual. Do not add oils directly to the water tank, as they can damage the heating element.
Are portable saunas safe for people with high blood pressure? The heat can raise your heart rate and temporarily increase blood pressure. Consult your doctor first. If you feel chest pain or severe headache, stop immediately.
Which type is easier to set up? Portable steam saunas require filling the generator and positioning the tent. Infrared tents are simpler—just unfold and plug in. Permanent infrared cabins require professional assembly.
