Traditional vs Infrared Sauna

The backyard sauna choice is simpler than it looks.

Infrared and traditional saunas are both excellent options. The honest answer is that they suit different spaces, different routines and different priorities.

Infrared is brilliant indoors: clean, low-maintenance, efficient and easy to live with. Traditional sauna is hard to beat outdoors, where heat, steam, timber and backyard aesthetics matter most.

The short version Infrared is a great indoor choice. Traditional owns the backyard.

If you want an indoor, low-maintenance wellness setup, infrared can be a smart option. If you want an outdoor centrepiece with proper heat, steam and that timber sauna ritual, traditional is the better fit.

They do not heat the same way.

A traditional sauna uses a heater and hot stones to heat the full room. The air gets hot. The cedar finish warms up. The stones hold heat. Then water can be poured over the stones to create steam and intensify the session.

Infrared works differently. Infrared panels radiate heat directly toward the body, usually at a lower air temperature. That can be a big advantage indoors: it is simple, efficient, comfortable and generally low-maintenance.

Traditional sauna

Heats the whole air volume, reaches higher temperatures, uses hot stones, creates steam, and delivers the classic Finnish-style sauna experience.

Infrared sauna

Uses radiant panels to warm the body directly at lower air temperatures. A great option for indoor, controlled spaces where you want convenience and low maintenance.

The feel is the whole point.

Traditional sauna feels immersive because the whole room is working. You are not just sitting in front of heat panels. You are surrounded by hot air, warm timber, hot stones and steam.

That is why traditional saunas have lasted for thousands of years. The session has a rhythm: heat up, pour water, sweat, cool down, go again. It feels like a ritual, not just a device.

Why people choose traditional

It gives the strongest sauna feeling: full-room heat, steam, intensity and a clearer recovery ritual.

Infrared is a great option indoors.

Infrared deserves its place. For an indoor wellness room, home gym, spare room or studio, it can be a really smart setup. It is convenient, clean, low-maintenance, quick to use and runs at a more approachable temperature.

That is the important distinction. Infrared is excellent when the environment is controlled. Traditional sauna comes into its own when the sauna becomes part of the backyard: beside a pool, on a deck, near an outdoor shower, or as a feature in the garden.

Two good options. Different jobs. Infrared is brilliant indoors. Traditional is hard to beat outdoors.

Australian backyards are a harder test.

Outdoor saunas in Australia deal with harsh sun, coastal air, humid days, colder winter nights and wind. A backyard sauna needs enough heat strength to create a consistent session even when the surrounding environment changes.

Traditional saunas have the advantage here. Because the full room is heated to a high temperature, the sauna has more thermal buffer. The heater, stones and cedar finish work together to hold the session steady.

The practical test.

If the sauna is going beside a pool, on a deck, in a garden, near an outdoor shower, or anywhere exposed to changing conditions, traditional heat and outdoor styling make more sense.

If the sauna is going into a sealed indoor room and you want a lower-maintenance, lower-temperature setup, infrared is absolutely worth considering.

So which one should you choose?

It is not about one technology being universally better. It is about where the sauna will live and what kind of experience you want.

Choose traditional if...

You want an outdoor sauna, proper heat, steam, hot stones, and the most authentic backyard sauna experience.

Choose infrared if...

You want an indoor sauna that is clean, convenient, low-maintenance, fast to use and suited to a controlled room-based setup.

For indoor wellness spaces, infrared can be a great choice. For most Australian outdoor homes, traditional is the better fit. It reaches proper sauna heat, handles steam, looks right in the backyard and gives you the experience people are usually imagining when they decide to build a sauna ritual at home.

Pick the sauna that fits your space. Infrared is a great indoor wellness option, but if you want the outdoor centrepiece — timber, steam, proper heat and backyard presence — these are the traditional Swell models worth comparing.
