Infrared Sauna vs Traditional Sauna
Infrared saunas use infrared emitters to heat you and the cabin directly, while traditional saunas heat stones and the surrounding air. Traditional saunas support water-on-stone löyly; infrared saunas do not. The better choice depends mainly on the heat experience you want, the electrical supply you have, the space available and your budget.
Everything below compares the two using Topture's current range — 18 infrared cabins and 78 traditional saunas — rather than general claims about saunas.
Infrared vs Traditional Sauna: Side by Side
| Dimension | Infrared | Traditional |
|---|---|---|
| Heating method | Infrared emitter panels heat the body and cabin directly | A heater warms stones, which heat the air in the room |
| Water on stones (löyly) | No — there are no stones | Yes, this is the defining feature |
| Operating temperature | Runs cooler; sessions tend to be longer | Runs hotter |
| Capacity in our range | 1–4 person | 2–8 person |
| Indoor / outdoor | 13 indoor, 5 outdoor — mostly indoor | 19 indoor, 59 outdoor — mostly outdoor |
| Electrical supply | 13 of 18 run on a standard 120V outlet; the rest need 240V | Determined by the heater specification, not the cabin |
| Price in our range | $2,698 – $8,995 | $3,496 – $75,028 |
How the Heat Actually Differs
A traditional sauna heats the air. The heater brings a bed of stones up to temperature, the stones heat the room, and you sit in hot air. Pouring water over the stones produces löyly — the burst of steam that raises the perceived heat and humidity. That ritual is the entire point for many buyers, and an infrared sauna cannot reproduce it, because there are no stones and no heater to pour onto.
An infrared sauna heats you rather than the room. Emitter panels built into the walls and benches radiate infrared, which is why these cabins run at a lower air temperature while still producing a heavy sweat. If you have found traditional saunas uncomfortably hot, this is the practical difference that matters.
Electrical Supply and Installation
This is where the two formats diverge most for a home installation, and it is measurable in our own catalogue.
Every one of our 18 infrared cabins publishes a voltage, and 13 of them run on a standard 120V household outlet. For those models there is no dedicated circuit and no electrician — you plug the sauna in. The remaining 5 need 240V.
For a traditional sauna the electrical requirement follows the heater rather than the cabin, which is why most of our traditional listings do not carry a cabin-level voltage figure. The number to check is the heater's kW rating and the circuit it requires. If you are pricing a traditional build, price the sauna heater and its electrical work at the same time as the room.
Space, Capacity and Placement
Our two ranges point in noticeably different directions.
- Infrared skews indoor and smaller. 13 of 18 cabins are indoor models, and capacity runs 1 to 4 people. These are built to go into a finished room.
- Traditional skews outdoor and larger. 59 of 78 are outdoor models, and capacity runs 2 to 8. If you need to seat more than 4 people, traditional is currently the only option in our range.
What Each Costs
Infrared runs from $2,698 to $8,995. Traditional runs from $3,496 to $75,028 — a far wider band, because it spans everything from compact indoor kits to large outdoor cabins. Entry prices are closer than people expect; the ceilings are not.
Remember the traditional figure is the sauna. Budget the heater separately unless a specific listing states it is included.
Which Should You Buy?
- Choose traditional if löyly matters to you, if you want higher heat, if you are seating more than 4 people, or if the sauna is going outdoors.
- Choose infrared if you want to plug it into a normal outlet, if you are fitting it into a finished indoor room, if you prefer a lower air temperature, or if you want the lowest entry price.

A Note on Health Comparisons
Most "infrared vs traditional" articles end with a verdict on which is healthier. We are not going to give one. Research on traditional sauna bathing, research on infrared light, and manufacturers' own product claims are three different bodies of evidence, and a finding in one does not transfer to another. What we can compare accurately is the equipment, the installation and the experience — which is what this page does.
Frequently Asked Questions
What is the actual difference between an infrared and a traditional sauna?
Traditional saunas heat the air, running between 150°F and 195°F (65°C-90°C), with steam produced by pouring water over hot stones. Infrared saunas use carbon or ceramic panels to emit light that warms your body directly, so the air stays cooler at 120°F to 150°F (49°C-65°C) while your core temperature still climbs.
How deep does infrared heat actually go?
Depth figures for infrared are quoted widely but vary by source, and no manufacturer in Topture's range publishes a verified penetration depth for their own emitters — so we do not repeat a number we cannot source.
What is documented is the wavelength band: far infrared covers the longest infrared wavelengths, near infrared the shortest. The practical difference you will actually notice is air temperature — an infrared cabin runs cooler than a traditional sauna while still producing a heavy sweat.
Which sauna format is easier to install at home?
Infrared, in most cases. All 18 of Topture's infrared cabins publish a voltage, and 13 of them run on a standard 120V household outlet — no dedicated circuit and no electrician. The remaining 5 need 240V.
For a traditional sauna the electrical requirement follows the heater rather than the cabin, so the number to check is the heater's kW rating and the circuit it needs. Price the heater and its electrical work alongside the room.
Which sauna format seats more people?
Traditional. Topture's traditional range runs from 2 to 8 person capacity across 78 active models, while the infrared range runs from 1 to 4 person across 18 models.
If you need to seat more than four people, traditional is currently the only option in our range. Traditional also skews outdoor — 59 of 78 are outdoor models — whereas 13 of our 18 infrared cabins are built for indoor rooms.
Which sauna typically uses less electricity?
Infrared saunas in Topture's current range generally use lower-powered electrical systems than traditional sauna heaters, and 13 of our 18 infrared models run on standard 120V power.
Traditional sauna electricity use depends heavily on the heater selected, cabin size, insulation, target temperature and session length — and rated heater power does not equal actual session consumption once the thermostat begins cycling. Compare the electrical specifications of the exact models you are considering rather than relying on a single per-session estimate.
