Short answer
Infrared cabins warm you mainly with radiant panels at lower air temperatures, about 43–57°C (110–135°F). Traditional saunas heat the room to about 66–91°C (150–195°F) and can give steam from water on the stones. There is no clear evidence that one type is healthier, so choose by heat preference, space, electrical supply and installed price.
The useful comparison is between two specific setups you could actually install and would enjoy using. Start with heat preference, room layout and the complete installed cost, and treat promised health outcomes separately from product specifications.
What is the difference between an infrared and a traditional sauna?
A traditional sauna heats the air in the room with an electric heater or a wood stove and a load of stones. An infrared cabin uses panels or emitters that warm your body more directly, so the air does not need to be as hot. Cleveland Clinic and Mayo Clinic both describe infrared as working at lower temperatures than a regular sauna.
| Decision | Infrared cabin | Traditional sauna |
|---|---|---|
| Heating method | Radiant panels or emitters warm exposed surfaces, including your skin; the cabin air also warms | An electric heater or wood-burning stove heats stones, room air and surfaces |
| Typical air temperature | About 110–135°F (43–57°C) | About 150–195°F (66–91°C) |
| Steam from stones | No — never pour water on infrared panels | Yes, when the specific stone heater and venue permit water |
| Electrical supply | Model-specific: voltage, current and optional upgrades can change the required circuit | Electric heater supply must match its manual; wood-fired saunas have chimney and installation rules instead |
| Space | Check finished dimensions, door swing, service access, clearances and indoor/outdoor rating | Check interior layout, benches, heater clearances, ventilation and installation requirements |
| Warm-up and energy | Use the model’s power and actual heating time | Include warming the room and stones, later cycling and any drying time |
| Maintenance | Follow cabin and panel cleaning instructions; keep electrical parts dry | Follow wood-care, heater and stone instructions; a stove adds combustion-system maintenance |
| Best reason to choose it | You prefer radiant warmth and the specific cabin fits your home | You want a classic hot room with löyly where permitted |
For what “dry” and “wet” mean, see dry versus wet sauna. A purpose-built steam room is a third category, covered in our infrared sauna vs steam room guide. Infrared cabins also differ by heater type — see infrared sauna types and ceramic vs carbon heaters.
How hot does each type get?
Cleveland Clinic describes infrared saunas at about 110–135°F (43–57°C) and traditional saunas at about 150–195°F (66–91°C). These are descriptive ranges, not targets you must reach or a fixed time to stay. Your model’s settings and manual set the real limits. More detail is in how hot infrared saunas get and average sauna and steam room temperatures.
Lower air temperature does not mean there is no heat strain. You still warm up, sweat and lose fluid, so the same basic precautions apply to both.
What does the heat feel like?
A traditional sauna is about the hot room. If the heater allows water, throwing it on the stones raises humidity and makes the heat feel stronger for a moment. An infrared cabin is about radiant warmth from the panels; where you sit relative to the emitters changes the experience. Our page on what an infrared sauna feels like goes into more detail.
If you can, try both before ordering. Check seat depth, headroom, door access and whether the advertised person count really gives you the space you want. Personal comfort is more useful than a marketing claim that one type is better for everyone.
Which is easier to install at home?
Neither is automatically easy. “Plugs into an ordinary outlet” is not a safe assumption for every infrared cabin. For example, Clearlight’s electrical requirements list the Premier 2 at 120 V / 15 A, the Premier 2 with a Full Spectrum upgrade heater or red-light option at 120 V / 20 A, and the Sanctuary 3 at 240 V / 15 A (checked 15.10.2026). Those are one maker’s examples; verify the current specification for your exact configuration.
For any cabin, check floor suitability, ventilation, assembly space, delivery access and clearances. Outdoor use needs a model rated for outdoors — a roof or sheltered corner does not make an indoor-only cabin suitable. See can an infrared sauna go outside and where to put a sauna in your home.
For a traditional electric sauna, match heater output to the adjusted room volume. Our heater size calculator gives a starting estimate including exposed glass or stone, but the manufacturer’s permitted room range and installation manual take precedence. Have a qualified electrician check the supply and the room design.
Which costs more to buy?
There is no honest single answer, because packages differ. Ask each seller to itemize the same costs so you compare like with like:
- Cabin or room materials, benches and exactly what is included.
- Heater, controls, stones and separately priced options.
- Delivery, access, assembly and site preparation.
- Electrical work, ventilation and any building or chimney work.
- Warranty coverage, spare parts and service.
Use a dated quote for the exact model and location instead of a generic “average price.” This guide has not tested products or surveyed every current retail price.
Which is cheaper to run?
Energy in kWh equals average power in kW multiplied by hours. These two examples use an illustrative rate of $0.20/kWh:
| Example | Heating assumptions | Energy | Cost per cycle |
|---|---|---|---|
| 2 kW infrared cabin | 15 minutes warm-up plus 30 minutes at full power | 1.50 kWh | $0.30 |
| 6 kW traditional electric heater | 30 minutes full-power warm-up plus 30 minutes at 50% average power | 4.50 kWh | $0.90 |
These are model calculations, not measured averages or equal heat doses. Thermostat behavior, insulation, room temperature and your schedule change the result, and the times describe heating time, not how long you should sit inside. Run your own numbers with the sauna cost calculator; the infrared electricity guide explains watts and kWh, and how long a sauna takes to heat up covers warm-up.
Is one type healthier?
A frequently cited 2015 Finnish cohort study (JAMA Internal Medicine) followed 2,315 middle-aged men for a median 20.7 years and found that more frequent sauna bathing was associated with lower risk of fatal cardiovascular events and death from any cause. It was observational, so it cannot show that buying a sauna causes those outcomes, and it did not compare home infrared cabins with traditional saunas.
Mayo Clinic says studies of infrared saunas found some signs of benefit for several long-term conditions, but larger and more exact studies are needed. Do not assume a seller’s detox, fat-loss or disease-treatment claims follow from research on a different kind of heat. Neither sauna replaces prescribed treatment. If you are pregnant, have a heart or blood-pressure condition, or take medication that affects heat tolerance, ask your doctor first. Our infrared sauna risks page lists common precautions.
Which should you buy?
- Steam from stones is essential: shortlist traditional saunas with heaters that permit water.
- You prefer gentler radiant warmth: try an infrared cabin, then verify the exact model’s size and electrical needs.
- You have a fixed room or garden spot: check construction, clearances and indoor/outdoor rating before shopping by seat count.
- You have a fixed budget: compare complete installed quotes and your own running-cost estimate.
- You only want occasional heat at home: compare a cabin with a portable option in sauna blanket vs infrared sauna.
Basic precautions apply to both: avoid alcohol, keep water nearby, and get out if you feel dizzy, sick or unwell. The NHS lists the signs of heat exhaustion and heatstroke. More general advice is in our sauna tips.
Frequently asked questions
Is an infrared sauna as good as a traditional sauna?
It depends on what you want. Both make you hot and sweaty. Cleveland Clinic says infrared tends to feel gentler, while a traditional sauna gives hotter air and steam from the stones. No head-to-head study shows that one home sauna type is better for health.
Which is hotter, infrared or traditional?
A traditional sauna. Cleveland Clinic describes infrared saunas at about 110–135°F (43–57°C) and traditional saunas at about 150–195°F (66–91°C). Lower air temperature still puts heat strain on your body, so leave if you feel unwell.
Can you add water to an infrared sauna?
Do not pour water on infrared panels or electrical parts. For steam from stones you need a heater designed and approved for water. A hybrid sauna must be used exactly as its own manual says.
Do infrared saunas need a special electrical circuit?
Some do. Clearlight, for example, lists its Premier 2 at 120 V / 15 A, the Premier 2 with an upgrade heater at 120 V / 20 A, and the Sanctuary 3 at 240 V / 15 A. Check the exact model and let a qualified electrician confirm the circuit.
Is an infrared sauna always cheaper to run?
No. Running cost depends on actual power, total heating time, thermostat cycling and your electricity tariff. A lower-power cabin often costs less per session, but your own schedule can change the comparison.
Does more sweating mean more benefit?
No. Sweat volume is not a score for health value, and it does not show that one sauna type works better. Choose a session that feels comfortable and safe rather than chasing a sweat target.
