Traditional vs Infrared 2-Person Outdoor Sauna: Key Differences Explained

Traditional outdoor saunas heat cabin air to about 170–200°F and support steam; infrared 2-person outdoor saunas warm the body directly at roughly 120–170°F and never produce steam.

That one contrast, air temperature versus radiant body heat, decides almost everything else: how long the unit takes to warm up, how much power it draws, what it costs to run, and whether you get the authentic Finnish-style steam pour at all. People often buy on price or looks, then discover the sauna they chose can’t do the thing they actually wanted.

This breakdown covers the real experience gap, plus the electrical and running-cost math. The table below shows how the two types line up on the numbers that matter.

How Do Traditional And Infrared Outdoor Saunas Actually Feel Different?

A traditional sauna feels like a hot room; an infrared sauna feels like warm, direct heat on your skin in a much cooler room. Traditional units heat the cabin air to about 170–200°F using an electric or wood heater, and you can pour water on the hot stones to make steam. That steam, called löyly in Finnish sauna culture, is the whole point for many bathers.

Infrared saunas, including the Sun Home Luminar line, warm the body directly through radiant heat and top out around 170°F, per Sun Home’s own product description. The surrounding air stays milder. There is no steam option at all, so anyone who wants the steam-and-stones ritual is looking at a traditional unit.

Neither style is “better.” Traditional wins on the classic hot-steam bathing environment. Infrared wins if you want to sit down, warm up fast, and not manage water or stones.

Which One Costs Less To Buy And Run?

Infrared typically costs less to operate and is easier to power, while traditional units cost more to run and usually need heavier electrical service.

Warm-up time splits the same way. Traditional saunas need 30–60 minutes to preheat. Infrared models reach temperature in 10–20 minutes.

Feature Traditional Outdoor Infrared Outdoor
Air temperature About 170–200°F About 120–170°F
Steam option Yes, water on hot stones No, dry heat only
Preheat time 30–60 minutes 10–20 minutes
Power draw at preheat Roughly 6–12 kW About 1.8–3.6 kW
Cost per session About $1.20 About $0.45
Typical voltage Often 240V Some 120V plug-in models
Example price About $3,600–$10,000+

What Should You Check Before Buying?

Verify the electrical requirement first, because it varies by model even within the same type. Many other infrared units need 220V or 240V, and traditional outdoor saunas commonly require 240V service and a dedicated circuit.

One published comparison of models and prices is worth checking alongside the manufacturer’s own page, since commercial roundups can lag behind current specs. our tested 2-person outdoor sauna roundup shows which models held up on voltage, price, and real interior room.

Two more traps to avoid. First, most infrared units are dry-heat only, so don’t buy one expecting steam. Second, “2-person” is a nominal label, not a comfort guarantee; interior bench depth varies a lot between a barrel and a cabin model.

FAQs

Can I add steam to an infrared sauna?

No. Infrared saunas are dry-heat systems and don’t use stones or water, so there’s no steam option. If steam matters to you, choose a traditional sauna with a heater and stone basket, then pour water over the stones to create löyly.

Does an outdoor infrared sauna need a dedicated circuit?

It depends on the model. Some 120V units plug into a standard outlet with no electrician, while others need 220V or 240V. Confirm the voltage and circuit rating on the manufacturer’s current page before you buy.

Which type is cheaper to run?

Infrared is generally cheaper. Actual costs depend on your local electricity rate and how long you stay in.
