Infrared Sauna vs Traditional (Finnish) Sauna: Which Should You Buy?

If you've been researching home saunas in Australia, you've likely run into this comparison early. Infrared and traditional Finnish saunas are both widely available, both deliver genuine health and recovery benefits, and both have passionate advocates. The differences between them are real and worth understanding before you spend a dollar.

Here's what you need to know.

How They Work

Traditional (Finnish) saunas heat the air. An electric heater or wood-burning kiuas warms a pile of rocks, which then radiate heat into the cabin. The air temperature climbs to somewhere between 70 and 100°C. Your body heats up because you're sitting inside a very hot space. Many traditional saunas also allow you to pour water over the rocks to produce steam, a practice known as löyly, which raises the humidity and intensifies the experience.

Infrared saunas work differently. Instead of heating the air, infrared panels emit radiant heat that is absorbed directly by your body. The cabin temperature sits much lower, typically between 45 and 65°C, and there's no steam involved. Your body still sweats and raises its core temperature, but the mechanism is the absorption of infrared wavelengths rather than convective heat from the surrounding air.

Different Experience

This matters if you've used a traditional sauna before and have strong feelings about it.

A Finnish sauna at 90°C with a splash of löyly is intense. The heat is dense and enveloping, the steam briefly spikes the humidity, and the whole experience has a ritualistic quality that many users find irreplaceable. Scandinavian and Finnish sauna culture is built around this specific sensory experience, and people who grew up with it often feel that nothing else quite compares.

Infrared sauna sessions are milder in terms of ambient temperature. The air around you isn't scorching, but your body heats up progressively as the infrared energy penetrates deeper into tissue. Many users find they can comfortably sit in a session for 30 to 45 minutes, read, or listen to a podcast in a way that would be difficult in a 90°C Finnish cabin.

Here's a straightforward way to think about it:

• If the intense heat, the steam ritual, and the traditional Nordic experience are specifically what you're after, a traditional sauna will satisfy that in a way that infrared doesn't replicate

• If you're focused on regular recovery, consistent sweating, and a comfortable daily-use routine, infrared tends to suit that better

• If you haven't used either and you're buying for the first time, the lower-temperature experience of infrared is often easier to build a habit around

The right one depends on what you're looking for.

Heat-Up Time

A traditional sauna needs 40 minutes or more to reach operating temperature. You need to plan ahead, which is fine if sauna use is a deliberate ritual but inconvenient if you want to hop in after training or before bed without much notice.

An infrared sauna is typically ready in 10 to 15 minutes. You switch it on, get changed, maybe have a glass of water, and it's at temperature by the time you're ready. That ease of access makes a real difference to how often people actually use it.

Installation Process

For Australian buyers, this is where the comparison gets particularly relevant.

Traditional saunas typically require:

• A dedicated 32A electrical circuit, which means a licensed electrician and potentially a new circuit run from your switchboard

• Proper ventilation to manage humidity, particularly in indoor installations

• Heat-resistant flooring and a drain if installing indoors

• In some cases, a licensed builder for the fitout, depending on your state and council regulations

• Substantially more planning and lead time before your first session

Infrared saunas under 2.4kW typically require:

• A standard 10A household powerpoint, the same outlet your washing machine or microwave uses

• No ventilation requirements, since there's no steam

• No tradesperson, no permits, no dedicated circuit in most residential setups

• Flat-pack delivery and a two-person assembly job that most people complete in a couple of hours

The installation difference is significant for homeowners who want to set up in a spare room, a garage, or a covered outdoor area without involving a builder or electrician. Most infrared saunas are genuinely plug-and-play in a way that traditional saunas are rarely.

Running Costs and Maintenance

Both types are relatively low-cost to run compared to a hot tub or pool.

A typical home infrared sauna draws between 1.4kW and 2.4kW depending on the model and how many panels are running. At average Australian electricity rates, a one-hour session costs roughly 35 to 65 cents. Monthly costs for regular daily users sit around $10 to $20.

Traditional electric saunas draw more power since they need to heat a much larger thermal mass to higher temperatures, and the extended warm-up time adds to the total energy use per session. Wood-fired units trade electricity costs for firewood, time, and the effort of managing a fire.

Maintenance for both types is straightforward. Infrared saunas need a post-session wipe-down and periodic deeper cleaning of the bench and floor. Traditional saunas need similar care, plus attention to the rocks over time (they degrade with repeated thermal cycling and need occasional replacement).

Quick Summary

Which One Should You Buy?

A traditional Finnish sauna is likely the right fit if:

• You have experience with traditional saunas and the heat and steam ritual is specifically what you want to recreate at home

• You have the budget for installation, including a dedicated circuit and any necessary building work

• You're prepared to plan sessions in advance rather than using it on impulse

An infrared sauna is likely the right fit if:

• You're new to home saunas and want something that's simple to set up and easy to use regularly

• You're working with a standard residential electrical setup and want to avoid electrician costs

• Daily use for recovery, relaxation, or general wellness is the goal

• You want a cabin that fits in a spare room and is ready in under 15 minutes

We recommend starting with a clear idea of how you plan to use it. Buyers who know they want the traditional Finnish experience from day one tend to feel confident going that direction. Buyers who are building a recovery or wellness routine from scratch tend to find infrared the more practical starting point.
