Infrared vs. Traditional Steam Sauna

This question comes up in almost every consultation we have. A buyer has done their research, narrowed down their budget, identified a few models they like — and then they ask: should I be looking at infrared or traditional steam?

The honest answer is that both work. Both have been used in professional wellness and recovery contexts for decades. The right choice comes down to what you're trying to accomplish, what your space allows for, and what kind of experience you actually want on a Tuesday morning before work.

Let's break down the real differences.

 

How Each Technology Actually Works

Traditional Steam Sauna

A traditional sauna uses a heater — electric or wood-fired — to heat a mass of rocks to very high temperatures. Water gets poured over the rocks, steam rises, and the air temperature in the room climbs to somewhere between 160 and 200°F. You're essentially sitting in a very hot, very humid room. Your body responds by sweating hard to cool itself down.

The experience is intense, immersive, and sensory in a way that's hard to replicate. The sound of water hitting hot rocks. The wave of steam. Ten minutes in and you know you're in a sauna.

Sessions typically run 10–20 minutes before you need to step out and cool down.

Infrared Sauna

An infrared sauna uses electromagnetic radiation — specifically infrared light — to heat your body directly rather than heating the surrounding air. The ambient temperature inside an infrared sauna sits around 120–150°F, well below a traditional sauna, but you sweat at comparable or higher levels because your core temperature rises from within rather than from the outside in.

For most people, the lower air temperature makes infrared sessions more comfortable to sustain — you can stay in longer, breathe more easily, and the experience feels less like enduring and more like recovering.

 

The Practical Differences That Actually Matter

Electrical Requirements

This is the biggest practical consideration for most home installations.

1 and 2-person infrared saunas run on standard 120V household current with a dedicated 15AMP circuit and 15AMP outlet (Non-CAFCI/Non-GFCI). Most homes can accommodate this without significant electrical work — it's just a matter of running a dedicated circuit.

3-person and larger infrared saunas require a dedicated 120V / 20AMP circuit with a 20AMP outlet (Non-CAFCI/Non-GFCI). Still standard household voltage, just a step up in amperage.

Traditional steam saunas with electric heaters — including the Golden Designs Arosa Barrel with its Harvia 6KW stove — require 240V service. That's the same voltage as an electric dryer. If you don't have 240V available near your installation point, plan for additional electrical work before your sauna arrives.

For homeowners who want a sauna with the simplest possible installation, infrared is the cleaner path.

Temperature and Comfort

Traditional steam runs hot and humid — 160–200°F with significant moisture in the air. For people who grew up with Nordic sauna culture or who specifically want that full-intensity experience, this is exactly the point. For people who are newer to sauna use or who have cardiovascular sensitivities, the intensity can be a barrier to consistent use.

Infrared sits at 120–150°F with low humidity. More approachable. Easier to use daily. Many people who find traditional saunas uncomfortable use infrared without issue.

Heat-Up Time

Traditional steam: 30–45 minutes to reach temperature.

Infrared: 10–15 minutes.

If you want to finish a workout and step directly into a sauna without planning ahead, infrared makes that practical. If your wellness practice is built around ritual and preparation, the traditional sauna's longer warm-up is part of the experience rather than an inconvenience.

Maintenance

Traditional steam saunas require more upkeep. Rocks need periodic replacement. The wood interior needs to stay dry between sessions. Outdoor units like the Arosa Barrel require weatherproofing attention and cover management through seasonal changes.

Infrared saunas are considerably lower maintenance. Wipe down the interior after sessions. Keep the glass clean. That's largely it.

The Experience Itself

This one's subjective but worth being honest about.

A traditional steam sauna feels like a ritual. The preparation, the heat, the steam, the community aspect of sharing the space — these sensory layers are part of why people who love traditional saunas love traditional saunas. It connects to a cultural practice that's been around for centuries and means something beyond just sweating.

An infrared sauna feels more like a therapeutic tool. You get in, set your temperature, and the session is quieter, more controlled, and often more focused on specific outcomes — recovery, relaxation, winding down before sleep. Many people prefer this precisely because it integrates naturally into a daily routine.

Neither is better. They're genuinely different experiences serving different preferences.

 

Full Spectrum vs. Standard FAR Infrared

Within the infrared category there's an important distinction worth understanding.

Standard FAR infrared saunas emit primarily in the far-infrared range — the longest wavelengths, which penetrate deepest into body tissue. This technology has been around for 20+ years and works well. A quality FAR-only unit delivers a legitimate infrared session.

Full spectrum infrared saunas emit across all three infrared ranges simultaneously:

Full spectrum units — including the Golden Designs Reserve Edition line and the Dynamic Lugano — deliver the complete picture in a single session. The addition of Near infrared also means you're getting red light therapy as part of your sauna session, which would otherwise require a separate device.

At the price difference between a quality FAR-only unit and a full spectrum unit — typically $500–$1,000 at the $3,000–$5,000 tier — full spectrum is the better long-term investment for most serious users.

 

Which One Should You Choose?

Choose infrared if:

Choose traditional steam if:

The most common choice among our customers is full spectrum infrared — specifically the Golden Designs Reserve Edition line — because it delivers the broadest range of wellness benefits in a format that works in most residential spaces without significant electrical modification.

The outdoor traditional barrel sauna — the Arosa (GDI-B004-01) — is the second most requested, typically by buyers who have the outdoor space and want a sauna that becomes the centerpiece of their backyard wellness environment.

If you're genuinely undecided, book a consultation. A 30-minute conversation about your space, your goals, and how you actually plan to use the sauna will make the right choice clear.
