Both a cryosauna and a cryotherapy chamber use extreme cold for recovery, performance, and wellness — but they’re not the same machine. A cryosauna is an open-top, single-person cylinder where the client steps in and their head stays above the chamber opening. A cryotherapy chamber is a fully enclosed walk-in cabin or room the client enters with their entire body, including the head. The cooling technology, session experience, footprint, price, and operating economics are all different — and so is the type of business each one serves best.

This guide breaks down every meaningful difference between the two — so you can decide which type of equipment fits your studio, your clients, and your ROI targets.

What Is a Cryosauna?

A cryosauna — also called a Partial Body Cryotherapy (PBC) device — is a vertical chamber the client stands inside while keeping their head above the rim. Most cryosaunas use liquid nitrogen vapor to drop the chamber temperature to between −110°C and −170°C (−166°F to −274°F) for sessions of 1 to 3 minutes.

Because the head stays in normal room air, the client never inhales nitrogen vapor. An electric lift inside the chamber raises or lowers the floor so the rim sits at the right height for clients of any size.

Cryosaunas are the most common cold therapy device in commercial wellness — compact, fast to operate, and built for high-throughput sessions. The CryoStar Vacuactivus is a flagship example: nitrogen-cooled, single-person, with optional thermal imaging and touchscreen controls.

Qu'est-ce qu'une chambre de cryothérapie ?

A cryotherapy chamber — Whole Body Cryotherapy (WBC) — is a fully enclosed cabin or room the client enters with their entire body, head included. The cooling system circulates extremely cold dry air around the whole body simultaneously.

There are two main types:

• Electric WBC chambers — use a refrigerated compressor to cool the chamber to roughly −85°C to −110°C. No liquid nitrogen is required, and the air inside remains breathable, so the client’s head stays inside the chamber for the entire 2–4 minute session. The Antarctique WBC électrique is the Vacuactivus electric walk-in model.
• Nitrogen WBC chambers — use vaporized nitrogen to reach lower temperatures (−140°C to −180°C). Because the air inside contains nitrogen, these systems require oxygen monitoring, ventilation, and trained operators. The Antarctique WBC Azote is the Vacuactivus nitrogen walk-in model.

WBC chambers cool the entire body — including the upper respiratory area — and clients describe the experience as “fully immersive” rather than “cold from the chest down.”

Cryosauna vs Cryotherapy Chamber: Side-by-Side Comparison

The biggest practical differences come down to coverage, cooling technology, footprint, and operating cost. Here’s how the two stack up at a glance:

How the Cooling Technology Differs

The biggest technical split is between nitrogen-based and electric cooling, and it cuts across both categories.

Most cryosaunas are nitrogen-only. Liquid nitrogen is injected into the chamber, evaporates, and the cold vapor surrounds the body. Sessions are short and intense, but the operator must manage liquid nitrogen tanks, exhaust ventilation, and oxygen monitors in the treatment room.

Cryotherapy chambers come in both flavors. Electric WBC chambers like the Antarctique WBC électrique use a closed-loop refrigeration system — no consumables, breathable air, dramatically simpler operation. Nitrogen WBC chambers like the Antarctique WBC Azote reach colder temperatures but require the same nitrogen handling infrastructure as a cryosauna, just at larger scale.

In short: if you want zero ongoing nitrogen costs and the simplest day-to-day operation, an electric WBC is the only path. If you want the absolute lowest temperatures, nitrogen wins — whether in a cryosauna or a chamber.

The Client Session Experience

How the session feels is one of the most underrated differences for a business, because it directly affects retention and per-client revenue.

In a cryosauna, the client stands in minimal clothing — shorts, socks, gloves, ear protection — with their head outside in normal room air. The cold hits the body fast and hard, but the breathing zone stays comfortable. Most first-timers tolerate this well.

In a walk-in chamber, the client enters a cabin or room and the cold surrounds them entirely. Electric chambers feel less aggressive than nitrogen at the same posted temperature, because dry refrigerated air transfers heat more gradually. Many clients prefer the walk-in feel — it’s quieter, less startling, and they can move freely inside.

For premium wellness positioning, walk-in chambers usually feel more “spa-like.” For fast, high-throughput recovery (athletes, rehab clinics), cryosaunas usually win on speed and simplicity.

Pros and Cons of Each

Cryosauna pros:

• Lower capital investment — the most accessible entry point into commercial cryotherapy
• Fast sessions — 1–3 minutes means high client throughput per hour
• Compact footprint — fits into a single treatment room with minimal renovation
• Established market — clients already understand the product, easier to promote

Cryosauna cons:

• Nitrogen logistics — recurring tank deliveries, storage, and ventilation requirements
• Head out only — some clients want full immersion, not just body cooling
• Per-session consumable cost — every session burns liquid nitrogen

Cryotherapy chamber pros:

• Whole-body immersion — premium feel and full-body cold exposure including the head
• Electric option = no consumables — long-term operating costs are dramatically lower
• Higher session price — clients will pay more for the walk-in experience
• Multi-person capacity — some chamber models accommodate two or three clients per session

Cryotherapy chamber cons:

• Higher capital cost — bigger machine, bigger upfront investment
• Larger footprint — a dedicated treatment room is required
• Claustrophobia — a small percentage of clients prefer the open-top format

Pricing, Operating Costs, and Long-Term ROI

Sticker price is only part of the equation. The real cost difference plays out over three to five years.

A nitrogen cryosauna has the lowest upfront cost but recurring liquid nitrogen expenses. Most studios spend several dollars per session in LN2, plus tank rental and delivery. At 600 sessions per year, that’s a meaningful operating line.

A nitrogen walk-in chamber carries the same nitrogen burn but at higher volume per session, since the larger chamber takes more cooling.

An electric walk-in chamber has the highest upfront investment of the three but the lowest ongoing operating cost — there’s no liquid nitrogen at all, just electricity. For high-volume facilities, the math often flips in favor of electric WBC inside two to three years of operation.

On the revenue side, walk-in chamber sessions typically command 20 to 40 percent higher pricing than cryosauna sessions in the same market. Premium spas, biohacking studios, and longevity-positioned facilities especially benefit from the walk-in price point.

Which One Should You Buy? A Decision Framework

Choose a cryosauna if:

• You’re opening a new recovery studio with limited initial capital
• Your business model is high-throughput athletic recovery
• You have a small treatment room and need a compact device
• You’re comfortable managing liquid nitrogen logistics

Choose an electric cryotherapy chamber if:

• You want the lowest per-session operating cost long-term
• You’re positioning as a premium wellness or longevity facility
• You don’t want to deal with nitrogen tanks, certifications, or exhaust systems
• You want to charge premium per-session prices

Choose a nitrogen cryotherapy chamber if:

• Your clients demand the absolute lowest temperatures
• You want walk-in immersion at maximum cold intensity
• You already have nitrogen infrastructure on site

Many established studios eventually run both — a cryosauna for fast solo sessions and a walk-in chamber as the premium-priced flagship offering. This dual setup also lets you cross-sell clients up from quick recovery to full-immersion sessions.

Foire aux questions

Can a cryosauna deliver the same results as a cryotherapy chamber?

For sports recovery and wellness purposes, both deliver an intense whole-body cold exposure. The main difference is that walk-in chambers cool the head and respiratory area too, while cryosaunas leave the head in normal room air. Skin temperature drop and rewarming response are comparable in well-designed equipment from either category.

Is electric cryotherapy as cold as nitrogen?

Posted temperatures are lower in nitrogen systems (−140°C to −180°C in WBC, down to −170°C in cryosaunas) than in electric chambers (−85°C to −110°C). However, dry electric cold transfers more gently, and the skin temperature outcome is closer than the numbers suggest. Many clients prefer the electric experience because it feels less aggressive at comparable physiological effect.

Do I need ventilation for both types?

Nitrogen-based equipment — both cryosauna and nitrogen WBC — requires dual exhaust ventilation and an oxygen monitor in the treatment room. Electric chambers like the Antarctique WBC électrique have no nitrogen and dramatically simpler installation requirements.

Can two clients share a single cryotherapy chamber?

Some walk-in WBC models — including certain Antarctica WBC chambers — accommodate two or even three clients per session, increasing throughput without adding equipment. Cryosaunas are single-person only.

Which is better for first-time customers?

First-time customers usually find a cryosauna less intimidating because the head stays outside the chamber. Walk-in chambers can feel more enclosed at first, but most clients adapt quickly and prefer the full-body experience after one or two sessions. Many studios start new clients in the cryosauna and upgrade them to the walk-in chamber on later visits.

Conclusion

A cryosauna and a cryotherapy chamber both deliver whole-body cold exposure for sports recovery and wellness, but they serve different business models. Cryosaunas like the CryoStar Vacuactivus win on capital efficiency and session speed. Walk-in chambers like the Antarctique WBC électrique et Antarctique WBC Azote win on premium positioning, full-body immersion, and long-term operating economics.

The right answer depends on your space, your capital, your clients, and your pricing strategy. Vacuactivus manufactures both categories — so you can match your equipment to your business model rather than the other way around.
