Infrared vs Traditional Saunas: Which Is Right for You?
This is the most common question new sauna buyers ask — and the answer depends on what you value most. Traditional saunas offer the authentic Finnish experience with intense dry heat and the option to create steam. Infrared saunas deliver a gentler heat that penetrates more deeply at lower temperatures. Both are legitimate wellness tools, but they feel very different in practice.
Common Scenarios
You want the authentic Finnish sauna experience
You want intense heat, steam from pouring water on hot rocks, and the social tradition of sauna bathing. A traditional sauna is the only option that delivers this experience. Budget $4,500-$15,000 for a quality installed setup.
You have limited space and a tight budget
You want daily sauna sessions but don't have room for a full build-out. Infrared saunas come in compact prefab units starting at $1,500 that plug into a standard 120V outlet — no dedicated circuit or contractor needed for a basic model.
Chronic pain or muscle recovery is your main goal
You want targeted heat therapy for sore muscles, joint stiffness, or chronic pain. Infrared's deep-penetrating heat works at lower air temperatures, making sessions more comfortable for people who find traditional saunas too intense.
How the Heat Works
Traditional Saunas
A traditional sauna heats the air in the room using an electric, gas, or wood-burning heater loaded with rocks. Air temperatures reach 150-195 degrees F with humidity around 10-20% (higher when you pour water on the rocks). Your body heats up primarily through convection — the hot air transfers heat to your skin.
Infrared Saunas
An infrared sauna uses carbon or ceramic panels to emit infrared radiation, which heats your body directly without significantly heating the surrounding air. The air temperature stays between 120-150 degrees F, but the infrared energy penetrates 1.5-2 inches into your skin and muscle tissue. The experience feels like sitting in warm sunshine.
Side-by-Side Comparison
| Factor | Traditional | Infrared |
|---|---|---|
| Temperature | 150-195°F | 120-150°F |
| Preheat Time | 30-45 minutes | 10-15 minutes |
| Session Length | 15-20 minutes | 30-45 minutes |
| Electrical Needs | 240V dedicated circuit (6-12 kW) | 120V standard outlet (1.5-3 kW) |
| Unit Cost | $3,000-$12,000 | $1,500-$6,000 |
| Monthly Energy Cost | $40-$75 | $15-$35 |
| Steam (Loyly) | Yes — pour water on rocks | No |
Health Benefits Compared
Both types deliver cardiovascular benefits, stress reduction, improved sleep, and muscle relaxation. Research published in journals like Mayo Clinic Proceedings and the Journal of Clinical Medicine supports benefits for both modalities.
- Traditional sauna: Stronger cardiovascular conditioning effect due to higher temperatures. More effective for producing a heavy, full-body sweat. Long-established research base — most clinical studies on sauna health benefits used traditional Finnish saunas.
- Infrared sauna: More accessible for people who cannot tolerate high heat (older adults, people with certain health conditions). Some evidence suggests deeper tissue penetration may benefit chronic pain and muscle recovery. Easier to use for longer sessions due to lower air temperature.
Which Should You Choose?
Choose traditional if you want intense heat, the steam experience, and the authentic sauna ritual. Choose infrared if you prioritize convenience, lower operating costs, and gentler heat — or if space and budget are limited. Many serious sauna enthusiasts eventually own both.

Is an infrared sauna as effective as a traditional sauna?
Both types produce real health benefits including improved circulation, stress relief, and muscle recovery. Traditional saunas heat the air to 150-195 degrees F for an intense full-body sweat. Infrared saunas operate at 120-150 degrees F but penetrate the skin more directly. Research supports benefits for both, though traditional saunas have a longer track record of clinical studies.
Do infrared saunas use less electricity?
Yes, significantly. An infrared sauna draws 1.5-3 kW compared to 6-12 kW for a traditional electric heater. A typical infrared session costs $0.50-$1.50 in electricity versus $3-$5 for a traditional sauna. Infrared saunas also require no preheating, so you save both time and energy.
Can you pour water on rocks in an infrared sauna?
No. Infrared saunas do not have a heater with rocks. The heat comes from carbon or ceramic panels that emit infrared radiation directly. If you want the traditional loyly experience of pouring water on hot stones to create steam, you need a traditional sauna with an electric or wood-burning heater.
