Commercial Infrared Sauna vs Traditional: Which Should You Stock?

Infrared saunas are everywhere in the wellness press right now, and every sauna distributor, importer, and facility owner faces the same question: which type should I stock or install, and which performs better in a commercial setting? It's a fair question — but the answer that works for a home buyer is often the wrong answer for a business. Let me break it down from a commercial point of view, not a consumer's.

For most commercial settings — gyms, hotels, spas — a traditional electric sauna is the more robust, higher-capacity choice[^1], while a commercial infrared sauna suits low-traffic wellness studios and clients who prefer a gentler, lower-temperature session. The right pick depends on your traffic, your positioning, and your running costs, not on which one is trending.

Before you compare heating types, make sure you're shopping commercial in the first place — the difference between a home and a commercial sauna is bigger than most buyers expect. Once that's clear, here's how infrared and traditional actually stack up for a paying facility.

How Is a Commercial Infrared Sauna Different from a Traditional One?

The two heat you in completely different ways, and that difference drives everything else — comfort, capacity, and cost.

A traditional sauna heats the air with an electric heater and rocks, warming the room to around 65–90°C[^2] so your body heats from the surrounding air. A commercial infrared sauna uses infrared emitters to warm your body directly at a much lower air temperature, typically around 43–57°C[^3], so the room feels gentler while still making you sweat.

Because infrared warms the body rather than the air, guests often find it more tolerable and can stay longer without the intense heat of a traditional room [^1]. A traditional sauna, on the other hand, delivers that classic high-heat, steam-and-löyly experience[^4] many spa and gym members specifically expect. Neither is "better" — they're different products for different audiences, and that's exactly the decision you're making for your facility.

What Are the Health Benefits Guests Are Looking For?

Your members don't buy heating technology — they buy how the session makes them feel. Knowing what each delivers helps you market it.

Both types make users sweat and raise the heart rate[^5], and research links regular sauna use to relaxation and cardiovascular benefits[^6]. Infrared's appeal is that it produces a similar effect at a lower, more comfortable temperature, which suits guests who can't tolerate intense heat.

Infrared saunas can create a workout-like response at lower temperatures, which makes them accessible to people who find a traditional sauna too hot [^2]. That said, the health research is still developing and no sauna is a medical treatment — so market the experience (recovery, relaxation, wellness) rather than making clinical claims. For a gym or spa, that "gentler but still effective" angle is a genuine selling point for a certain type of member.

Which Handles Commercial Traffic Better?

This is where the home-versus-business gap really shows. A unit that's perfect in someone's garage can struggle under all-day commercial use.

Traditional electric saunas are generally better suited to high, continuous commercial traffic — they reheat quickly between guests and hold up to constant back-to-back sessions. A commercial infrared sauna is often a smaller-capacity, cabin-style unit better matched to lower-volume, appointment-based wellness settings.

Think about your peak hour. A busy gym or hotel spa with a steady stream of users needs a room that recovers heat fast and seats several people at once — that's traditionally the traditional sauna's strength. Many infrared units are designed for one to a few users, which fits a boutique studio or a private wellness suite far better than a packed 6 p.m. gym floor. Match the technology to your throughput, or you'll create a bottleneck.

Which Costs More to Run?

Sticker price is only half the story for a business. What matters is the daily cost of keeping the amenity open.

Infrared saunas generally draw less power per session and heat up almost instantly, which can lower running costs for low-traffic use. Traditional saunas use more energy to heat the air but serve more people per session, so cost-per-guest can actually be lower in a high-traffic facility.

Here's the operator's math: an infrared unit sitting idle most of the day, switched on per booking, is cheap to run. But a traditional sauna serving 8 people at once during a busy block spreads its energy cost across far more guests. So the real question isn't "which uses less electricity" — it's "which gives me the lowest cost per paying guest at my actual traffic level." Run that number against your peak hours before you decide.

Use this as a starting filter, then pressure-test it against your own venue, traffic, and brand positioning.

Conclusion

A commercial infrared sauna is a strong fit for boutique studios and wellness suites where sessions are gentle, private, and appointment-based. But for a gym, hotel, or busy spa serving many guests through a peak hour, a traditional electric sauna usually wins on capacity, durability, and cost-per-guest. Decide on your traffic and positioning first — the heating technology should follow that, not the trend cycle.

If your setting is a busy gym, hotel, or spa serving guests through peak hours, a traditional electric sauna is almost always the more robust, higher-capacity choice — and that's exactly what we build.
