What Is a Multiplace Hyperbaric Chamber?

For most people, hyperbaric oxygen therapy brings to mind a single-person tube — one patient, one session, alone. That picture is accurate for a large portion of the market. It’s not the whole picture.

Multiplace hyperbaric chambers accommodate two or more people at once. Depending on the model, that could be a couple doing sessions together at home, a family supporting a member going through a recovery protocol, two athletes finishing a training block, or a wellness center running back-to-back group bookings with three clients in the chamber simultaneously.

The technology is the same as a single-person hard chamber. The experience is fundamentally different.

How a Multiplace Chamber Works

The core mechanics of hyperbaric therapy don’t change with the number of occupants. The chamber pressurizes to a set ATA level, and the elevated pressure allows significantly more oxygen to dissolve into the bloodstream and tissues than is possible at normal atmospheric pressure. That’s the mechanism behind the recovery, anti-aging, and therapeutic effects the therapy is known for.

What changes in a multiplace configuration is how oxygen is delivered. In a single-person monoplace chamber, the entire chamber is typically flooded with oxygen. In a multiplace chamber, the interior is pressurized with air, and each occupant receives concentrated oxygen through an individual BIBS mask — a Breathing Interface and Breathing System. The mask delivers oxygen on the inhale and channels carbon dioxide out of the chamber through a scrubber. Each person’s oxygen delivery is independent, which means different occupants can receive different flow rates or protocols within the same session if needed.

In practical terms, occupants in a multiplace chamber are sitting upright, wearing a mask during the oxygen delivery portion of their session, and otherwise free to watch television, talk, read, or rest for the duration.

Who Uses Multiplace Chambers

The range of buyers in this category has expanded considerably as the chambers have become more accessible outside of hospital settings. In 2026, four distinct groups account for most multiplace purchases.

Families and couples are the fastest-growing home buyer segment for multiplace chambers. The appeal is straightforward: two people can do their sessions simultaneously rather than sequentially, which halves the time commitment for households where both partners or multiple family members are committed to regular hyperbaric therapy. For families supporting a member managing a chronic condition or long-term recovery protocol, the option for a caregiver or family member to accompany them in the chamber changes the experience significantly, particularly for elderly patients, children, or anyone managing anxiety in an enclosed space.

Athletes and training partners use multiplace chambers to build shared sessions into their recovery routines. Professional sports organizations have long used multiplace configurations for exactly this reason — Oxygen Health Systems has supplied chambers to NFL and MLB organizations where post-game and post-training recovery happens in groups rather than one at a time. The same logic applies at the serious amateur level, where training partners and coaches working the same schedule benefit from running sessions together.

Wellness centers and medspas use multiplace chambers as a premium service category with better unit economics than single-person monoplace setups. At similar per-session pricing, treating two or three clients simultaneously changes the revenue math considerably. The shared session experience also differentiates these facilities from competitors who offer only monoplace options — the walk-in, sit-down, lounge-style atmosphere of a well-appointed multiplace chamber is a genuinely different product.

Luxury home buyers are a smaller but growing segment. These are buyers building out dedicated wellness rooms in larger homes, often alongside cold plunge, red light therapy, and infrared sauna installations, who want the chamber to function as a premium home amenity rather than medical equipment. Several Oxygen Health Systems multiplace configurations have been purchased by private buyers who’ve specified massage tables inside, custom interiors, and four-person configurations for estate wellness rooms.

The Experience: What It’s Actually Like

This matters more than it might seem, because the experience of a multiplace session is meaningfully different from a monoplace session and sells itself differently to different buyers.

Walking into a monoplace vertical hard chamber, you’re in a private, contained space. The session is focused and individual. Most people find it comfortable, particularly compared to lying soft chambers, but it’s still a single-occupancy environment.

Walking into a large-format multiplace chamber is a different experience entirely. Oxygen Health Systems’ 64-inch multiplace chambers are up to 120 inches long. There’s room to sit comfortably, stretch out, and move around. The chambers come with integrated LED lighting, entertainment systems, and fully customizable interiors including seating, flooring, and interior lining. Air conditioning and dehumidification are built in. In a high-specification configuration, spending 90 minutes in one of these chambers is genuinely pleasant rather than something to be endured.

For wellness centers building a membership model, that experience difference is a product in itself. For couples using the chamber at home, it changes how the therapy fits into daily life — sessions become something you do together rather than time one person spends alone in a room.

The OHS Multiplace Lineup

Oxygen Health Systems offers multiplace configurations across several form factors, designed to serve different buyer types and space requirements.

The 44-inch walk-in multiplace is the entry point in the multiplace range. It accommodates two people seated comfortably and fits in a dedicated treatment room without requiring major facility changes. For wellness centers adding their first multiplace configuration, or couples buying for home use who want shared sessions without a large footprint, this is the starting point.

The 64-inch multiplace is available in 79-inch, 99-inch, and 120-inch lengths. These chambers accommodate two to four occupants depending on configuration. The 79-inch seats two comfortably with room for entertainment and easy movement. The 99-inch adds meaningful space for three occupants or for two who want a more spacious session. The 120-inch is the large-format option — it’s the configuration that professional sports teams and high-end wellness facilities typically specify, and the one where the “premium amenity” experience is fully realized.

All multiplace configurations from Oxygen Health Systems include:

Single-touch pressure selection to 1.3, 1.6, 1.8, or 2.0 ATA
Integrated air conditioning and dehumidification
BIBS mask system with individual oxygen delivery and CO2 scrubbing per occupant
Auto-depressurization with quiet, timer-synchronized pressure release
Dual redundant compressors
Emergency door release on both the inside and outside of the chamber
Three-year manufacturer’s warranty

Interior colors, seating configuration, flooring, and lighting are customizable across the lineup.

Multiplace vs. Monoplace: Choosing the Right Configuration

The decision between a multiplace and a single-person vertical chamber comes down to three things: how many people will regularly use the chamber, what experience you’re trying to create, and what the space and budget allow.

For wellness centers and medspas, the calculus is largely about throughput. A monoplace chamber running six to eight sessions per day generates a clear return that’s easy to model. A multiplace chamber running the same schedule but treating two or three occupants per session changes the revenue picture considerably, provided the booking volume is there to support it. Most wellness centers starting with hyperbaric for the first time are better served by a monoplace that lets them build patient volume without the larger capital commitment, then upgrading to a multiplace when utilization justifies it.

For home buyers, the choice is simpler: if you have a partner, family member, or regular training partner who will use the chamber consistently alongside you, a multiplace configuration is worth the additional investment. Sequential sessions in a monoplace work, but they roughly double the daily time commitment compared to running both people in the same session.

For buyers focused on the luxury or biohacking market, the multiplace experience is often part of the point. The shared, spacious, high-spec environment is a different product from a clinical monoplace unit, and buyers in this segment tend to want the best-in-class option rather than the practical starting point.

Space and Infrastructure

Multiplace chambers need more planning than monoplace units, particularly for home installations.

The 44-inch walk-in model needs a dedicated room of roughly 150 square feet minimum. The 64-inch models need more, ranging from around 200 square feet for the 79-inch length to 300-plus square feet for the 120-inch. Plan for the chamber footprint plus clearance on all sides for door swing, patient movement, and equipment access.

Electrical requirements vary by model and need to be assessed before purchase. All configurations require dedicated circuits. Oxygen Health Systems provides specific electrical and ventilation requirements for every model during the consultation process.

For home installations where doorway access is a constraint, confirm delivery configuration before purchasing. Several Oxygen Health Systems models are available in two-piece configurations specifically designed to pass through standard 36-inch American doorways.

Common Questions

How is oxygen delivered in a multiplace chamber if multiple people are inside? Each occupant receives oxygen through an individual BIBS mask rather than breathing from a shared oxygen-enriched atmosphere. The mask delivers oxygen on the inhale and channels carbon dioxide out through a scrubber. This means each person’s oxygen delivery is independent and can be adjusted individually within the same session.

Can people with different health goals use the same multiplace session? Generally yes. Since oxygen delivery is individualized through the BIBS mask system, occupants in the same chamber can follow different protocols at different flow rates. The session pressure is shared across all occupants, so the ATA level is set for the session rather than per person.

What does a multiplace hyperbaric chamber cost? Oxygen Health Systems’ multiplace configurations start around $55,000 to $60,000 for the 44-inch walk-in model and scale up based on size and specification. Large-format 120-inch configurations run considerably higher. All configurations include the full feature set: air conditioning, BIBS mask system, auto-depressurization, dual redundant compressors, and three-year warranty.

How much space does a multiplace chamber need in a home? At minimum, a dedicated room of 150 to 200 square feet for the entry-level walk-in model, with additional space for larger configurations. The room needs adequate ventilation and dedicated electrical circuits. Oxygen Health Systems can provide specific room requirements and can advise on two-piece delivery options for homes with standard doorways.

Are multiplace chambers used in professional sports? Yes. Oxygen Health Systems has supplied multiplace chambers to professional NFL and MLB organizations. Post-training and post-game recovery in groups rather than sequentially is one of the primary reasons professional sports facilities choose multiplace configurations.

What’s the main reason wellness centers choose multiplace over monoplace? Throughput and the client experience. A multiplace chamber treating two or three clients per session at similar per-session rates changes the revenue model significantly compared to a monoplace. The walk-in, lounge-style experience also differentiates a wellness center’s hyperbaric offering from competitors running standard monoplace units.

The multiplace chamber category has moved well beyond its clinical origins. What was once primarily hospital equipment is now found in private homes, chiropractic centers, medspas, and high-end wellness facilities, built for buyers who want shared sessions, premium experiences, or simply better throughput.

Oxygen Health Systems has been manufacturing and delivering multiplace configurations to buyers across all of these categories for over ten years. Our chambers are built in the United States, backed by three ISO certifications, and carry a three-year manufacturer’s warranty. If you’re working through whether a multiplace configuration fits your home or your facility, we’re glad to work through the specifics with you.
