infrared vs traditional sauna: which is right for your home?

If you're buying a sauna for home, the first real decision isn't the brand or the timber – it's the type of heat. A traditional sauna warms the air around you to 70-90°C, so the heat comes at you from the room. An infrared sauna skips the air and uses panels to warm your body directly, at a much gentler 45-60°C. That one difference drives almost everything else: what it costs, how it feels, how hard it is to install, and even which health research applies to it.

Here's the honest part up front: we make sauna hats, not saunas. We don't have a unit to sell you either way, which means this comparison isn't quietly steering you toward the thing on our shelf. Most “infrared vs traditional” guides you'll find are written by retailers who only sell one of the two – usually infrared – so the verdict is decided before you start reading.

Key takeaways:

• Infrared saunas are cheaper to run – roughly $8-10 a month at three sessions a week, versus $20 or more for a traditional electric sauna at typical Australian electricity rates (Spaworld, 2026).
• Infrared is easier to install (often a standard power point) and gentler, so you can stay in longer – usually 30-40 minutes versus 10-20 in a traditional sauna.
• Traditional saunas deliver the authentic high-heat, steam experience – and carry the strongest research pedigree: Finnish men who bathed 4-7 times a week had a 63% lower risk of sudden cardiac death than once-a-week users (Laukkanen et al., 2015).
• There's no universal winner. Choose on space, budget, and the kind of heat you actually want.

After a year of talking to customers about how they use their saunas, the type question comes up constantly – usually phrased as “did I buy the right one?” The answer almost always comes back to what they wanted in the first place, not which unit is objectively better. So that's how this guide is built: not toward a winner, but toward your winner.

what's the real difference between an infrared and traditional sauna?

The difference is the heating mechanism, and everything else follows from it. A traditional sauna heats the air – usually with an electric or wood-burning heater topped with rocks – until the whole room sits between 70°C and 90°C. An infrared sauna uses carbon or ceramic panels to emit infrared waves that warm your body directly, while the surrounding air stays far cooler, around 45-60°C.

That's why the two feel completely different even when both are “hot.” In a traditional sauna, the heat presses in from every direction, and you can throw water on the rocks for a burst of steam – the Finnish löyly. In an infrared cabin, the air feels mild and breathable; the warmth builds in your skin and muscles rather than your lungs. Neither is “more real” than the other. They're just two routes to the same destination: a deep, deliberate sweat.

If you're still mapping out the whole project – where it goes, what you'll need, how often you'll use it – start with our complete guide to setting up a home sauna, then come back here to settle the type.

how do they actually feel to sit in?

Traditional saunas feel intense and enveloping; infrared feels lighter and lets most people sit longer. Because the air in an infrared cabin stays around 45-60°C, the heat is far easier to tolerate, and a typical session runs 30-40 minutes. In a traditional sauna at 70-90°C, most people last 10-20 minutes before they need to step out and cool down.

So which is “better” depends on what you're chasing. Want the cleansing, slightly punishing heat that Finnish sauna culture is built on, plus the option of steam and that distinctive wood-and-smoke atmosphere? That's traditional. Prefer a milder warmth you can sit in with a book for half an hour without feeling like you're being cooked? That's infrared. The best sauna for you is the one you'll actually use – the gentlest infrared cabin in the world does nothing sitting unused, and neither does the most authentic Finnish room if the heat puts you off after five minutes.

near, mid and full-spectrum infrared: if you go infrared, you'll see these terms. Near-infrared penetrates deepest, far-infrared produces the bulk of the gentle radiant heat, and full-spectrum units cover the whole range. Most Australian home buyers now choose full-spectrum for the broadest experience – but it's a refinement, not a dealbreaker. Any reputable infrared unit will warm you properly.

what does each cost to buy and run in australia?

Infrared wins on cost, both upfront and ongoing. Infrared cabins are generally cheaper to buy than a comparable traditional sauna once installation is included, and they're markedly cheaper to run: around 20-40 cents an hour versus 60-90 cents for a traditional electric heater (Inner Light Sauna, 2026). Across a normal week, that works out to roughly $8-10 a month for infrared against $20 or more for traditional, at three sessions a week (Spaworld, 2026).

Why such a gap? A traditional heater has to bring an entire room of air up to 80-odd degrees and hold it there. Infrared panels only have to warm you, so they draw less power and reach working temperature faster. To put a real number on it: a two-person infrared sauna used for 30 minutes every day costs about $102 a year to run at the national-average electricity rate – around $8.50 a month (Inner Light Sauna, 2026).

Then there's the cost you don't see on the price tag. A traditional electric sauna often needs a dedicated higher-amp circuit and a licensed electrician to wire it in, plus ventilation work. Many home infrared units simply plug into a standard power point. Factor that in before you compare sticker prices, because the install can quietly close – or widen – the gap.

which is easier to install and maintain?

Infrared is the easier install and the lower-maintenance option of the two. Most infrared cabins arrive prefabricated and run off a standard Australian power point with minimal ventilation, so many people set them up in a spare room over a weekend. A traditional sauna is more of a project: it usually needs a hardwired higher-amp supply, a licensed electrician, and proper ventilation and moisture management, since you're deliberately making a room hot and humid.

Maintenance splits the same way. An infrared cabin mostly needs a wipe-down to keep the interior clean. A traditional sauna asks for a bit more care – the timber benefits from periodic treatment to resist warping, and the heater rocks need replacing now and then. Neither is onerous, but if “set it up and largely forget it” is the goal, infrared gets you there with less fuss.

A quick Australian note: if you're putting either unit outdoors – a barrel sauna on the deck, say – weatherproofing matters more here than the Nordic guides assume. Our summers are hard on timber and seals. We cover siting, power and ventilation in more depth in the home sauna setup guide, so I won't repeat all of it here.

are the health benefits the same?

Both deliver real benefits – but be careful who's telling you they're identical, because the evidence isn't evenly split. The largest, longest studies on sauna and longevity were done on traditional Finnish saunas. In a 20-year study of more than 2,000 middle-aged Finnish men, those who bathed 4-7 times a week were 63% less likely to suffer sudden cardiac death, and around 50% less likely to die of cardiovascular causes, than men who went just once a week (Laukkanen et al., JAMA Internal Medicine, 2015). A later Mayo Clinic Proceedings review confirmed that regular sauna bathing lowers blood pressure and improves blood-vessel function, with effects that resemble moderate exercise (Mayo Clinic Proceedings, 2018).

Infrared has genuine evidence too – it's just younger and smaller in scale. A 2025 review in Frontiers in Cardiovascular Medicine concluded that sauna heat, including infrared, supports cardiovascular health through better blood-vessel function and lower blood pressure (Frontiers in Cardiovascular Medicine, 2025). Far-infrared “Waon therapy” has been shown to improve heart function in clinical settings. The honest takeaway: both are good for you, but if a retailer tells you infrared is medically proven superior, they're getting ahead of the science. The gap is in study volume, not in proof that one fails.

what about emf and other concerns?

The question we hear most about infrared is EMF – electromagnetic fields from the panels – and it's a fair one. Reputable infrared brands now build low-EMF heaters and publish independent test results to back it up: a unit is generally considered low-EMF under 10 milligauss, and ultra-low under 3, measured at the seated position rather than at the panel itself (Backyard Discovery, 2026). The catch is that the term is unregulated – any brand can print “low EMF” without a single number behind it – so ask to see a third-party test report rather than taking the marketing at face value. A traditional sauna sidesteps the question entirely, because there are no infrared panels – just a heater and hot air.

Beyond EMF, the trade-offs are about experience. Infrared can't give you steam, so if löyly – that hit of humid heat off the rocks – is part of why you want a sauna, traditional is the only one that delivers it. On the other side, the lower air temperature of infrared is a genuine advantage if you find traditional heat overwhelming, or you want to sit in for longer without it becoming an endurance test. Worth weighing honestly against how you actually like to feel the heat.

so which sauna should you choose?

It comes down to three things: your space, your budget, and the kind of heat you want. Here's the short version.

choose infrared if: you want the lower running cost, the easiest install (often just a power point), gentler heat you can sit in for 30-40 minutes, and minimal maintenance. It suits smaller spaces, tighter budgets, and anyone who finds high heat hard going.

choose traditional if: you want the authentic Finnish experience – high heat, the option of steam, that wood-fired atmosphere – and you're happy to invest more upfront and in install. It also carries the strongest research pedigree if the long-term health evidence matters to you, and you've got the space, the wiring, and the appetite for a bit of upkeep.

One small thing worth knowing whichever way you go: the hotter the sauna, the more your head feels it, because the air near the ceiling is hottest. That's where a wool sauna hat earns its place – it insulates your head so you can keep absorbing heat comfortably, which matters far more in a high-heat traditional sauna than a mild infrared one. We explain why in our guide to the benefits of a sauna hat. Once you've picked your type, the home sauna setup guide walks through everything else.

infrared vs traditional sauna: frequently asked questions

Is an infrared or traditional sauna better for home use?

Neither is universally better – it depends on your priorities. Infrared wins on lower cost, easy installation and gentler heat; traditional wins on the authentic high-heat, steam experience and the strongest longevity research. Choose based on your space, budget and the kind of heat you want.

How much does it cost to run an infrared vs traditional sauna in Australia?

At typical Australian electricity rates, an infrared sauna costs roughly $8-10 a month at three sessions a week, while a traditional electric sauna runs around $20 or more a month. Infrared draws 20-40 cents an hour against 60-90 cents for traditional (Inner Light Sauna, 2026).

Do infrared saunas have the same health benefits as traditional saunas?

Both improve cardiovascular health, recovery and relaxation, but the largest longevity studies were done on traditional Finnish saunas – 4-7 weekly sessions cut sudden cardiac death risk by 63% (Laukkanen et al., 2015). Infrared evidence is promising but smaller in scale.

Are infrared saunas safe? What about EMF?

Yes. The main concern is EMF from the panels. Reputable infrared brands build low-EMF heaters – generally under 10 milligauss, ultra-low under 3, measured at the seat – and publish independent test results (Backyard Discovery, 2026). Because the term is unregulated, ask to see third-party reports. Traditional saunas have no panels, so the question doesn't arise.

Do you need a sauna hat in an infrared sauna?

It's less essential than in a traditional sauna. A sauna hat insulates your head from the hottest air near the ceiling, which matters most at the 70-90°C of a traditional sauna. In a milder 45-60°C infrared cabin the benefit is smaller, though some people still prefer it for comfort.

the bottom line

There's no winner here, and anyone who tells you otherwise is probably selling you one of them. Infrared is the easier, cheaper, gentler option – lower to run, simple to install, mild enough to sit in for half an hour. Traditional is the authentic one – higher heat, real steam, and the deepest bench of research behind it – in exchange for more cost, more install, and a little more upkeep.

So go back to the three questions: how much space have you got, what's your budget, and do you want gentle warmth or proper Finnish heat? Answer those honestly and the right sauna picks itself. When you've decided, our home sauna setup guide covers everything that comes next – siting, power, and building the habit so the thing actually gets used for years, not months.
