Summit to Sea Grand Dive Pro Plus Hyperbaric Chamber
The Grand Dive Pro Plus is the widest chamber in Summit to Sea's current range at 60 inches — five feet across — operating at 1.3 ATA (4.4 PSI). It is built around accessible entry: a circumferential opening that takes a wheelchair, four redundant compressors, four air relief valves, and enough interior room for a second person to be inside during a session.
Wellari Expert Take
Who the Grand Dive Pro Plus Suits
Chamber choice in the Summit to Sea range comes down to internal space and access, not pressure — every chamber in Summit's current lineup operates at the same 1.3 ATA (4.4 PSI). What changes between models is diameter, length, orientation and how you get in.
Sixty inches is a different category of space. At five feet across this is not a chamber you lie down in and stay still — Summit designs it so a wheelchair can be rolled in, so a person who cannot sit fully upright can recline, and so a second person can be inside alongside. A reclining chair fits. That is a genuinely different proposition from a chamber you climb into.
Four compressors, not two. The larger volume is pressurised by four units rather than the two used on the smaller chambers, with four air relief valves holding the ceiling at 4.4 PSI. It still runs from an ordinary 120V 15 A outlet.
Best For
- Wheelchair users, including anyone who cannot sit fully upright and needs to recline
- Sessions where a second person needs to be inside the chamber
- Practitioner and clinic settings where accessible entry is a requirement, not a preference
- Buyers who want a reclining chair inside rather than a floor mat
- Rooms that can genuinely accommodate a five-foot diameter chamber
Grand Dive Pro Plus Features & Buying Details
Pressure & Performance
- Operating pressure: 1.3 ATA (4.4 PSI)
- Pressure control: four air relief valves, for safely achieving a maximum of 4.4 PSI
- Auxiliary valves: two, one at each end of the chamber
- Compressors: four high-efficiency electric compressors, run in redundancy
- Air handling: patented sound suppression, plus in-line air filtration
Four compressors is a capacity decision, not a performance claim. A 60-inch chamber holds considerably more air than a 26- or 33-inch one, and Summit specifies four units to pressurise it — with the redundancy benefit that a single compressor fault does not end a session.
Four air relief valves hold the chamber at a maximum of 4.4 PSI, with an auxiliary valve provided at each end.
Size, Access & Interior
- Diameter: 60 inches (5 feet)
- Viewing windows: two large windows
- Entry: large opening with double-sided circumferential zippers, operable from inside or outside
- Wheelchair access: a wheelchair can be rolled in; a user unable to sit fully upright can be slightly reclined
- Room for two: Summit specifies enough interior space for a second person to be inside alongside the user
- Seating options: a reclining chair can be used inside, or the supplied foam mat
- Chamber weight: approximately 50 lb
On the chamber length. Summit offers this model in two lengths at different prices. We are not stating which length ships, because that is not currently confirmed and you cannot select it on this page. Contact us before ordering and we will confirm the exact chamber length in writing. If your room has a hard length limit, resolve this first — the difference between the two is about two feet.
Electrical & Installation
- Supply: standard 120V 15 A outlet
- Frame: external furniture-grade PVC frame, included
- Siting: level floor, with clear approach for a wheelchair at the entry
Summit to Sea specifies that this chamber works on an ordinary 120V 15 A household circuit despite using four compressors. No dedicated or high-voltage supply is called for in the manufacturer's documentation.
Plan the approach, not just the footprint. A wheelchair-accessible chamber is only accessible if there is a clear, level route to the opening with room to manoeuvre. That approach space is usually the real constraint rather than the chamber diameter itself.
On running costs: we do not publish an operating-cost estimate. Consumption depends on session length, frequency and ambient conditions, and the manufacturer publishes no duty-cycle data.
What Is Included
- Chamber with two large viewing windows
- Four high-efficiency electric compressors with patented sound suppression
- In-line air filtration
- External furniture-grade PVC frame
- Foam mat
- Carrying case
- Four air relief valves and two auxiliary valves
A wheelchair, stretcher or reclining chair is not included. The chamber is designed to accommodate them; supplying them is separate.

Warranty terms, coverage and claim procedures are set by the manufacturer and may vary by component. Review the manufacturer's current warranty documentation for the terms that apply to your chamber, and keep your purchase documentation for future support reference.
Prescription & Ordering Process
This chamber is a prescription device. After you order, Wellari will request a valid prescription from a licensed healthcare provider. We verify it and retain it on file as part of our order-verification process, and the chamber is released for fulfillment once that step is complete.
If you have questions about the prescription requirement — including how to obtain one, or whether your existing documentation is suitable — contact us before ordering and we will walk you through it.
We do not provide prescriptions, and we do not advise on whether hyperbaric use is appropriate for you. That is a conversation for a qualified healthcare professional who knows your history.

Common Questions
Do I need a prescription to buy this chamber?
Yes. This chamber is a prescription device. After you order, Wellari will request a valid prescription from a licensed healthcare provider, verify it, and retain it on file as part of our order-verification process before the chamber is released for fulfillment. Contact us before ordering if you have questions about how the requirement applies to you.
How long is the chamber?
We are not stating a length. Summit offers this model in two lengths at different prices, and the stocked configuration is not currently confirmed. Contact us and we will confirm the exact length in writing before you order — this matters if your room has a hard length limit.
Can a wheelchair go inside?
Yes. Summit designs the entry so a wheelchair can be rolled in, and a user who cannot sit fully upright can be slightly reclined. The wheelchair itself is not included.
Can someone else be inside with the user?
Yes. Summit specifies enough interior room for a second person alongside — which is the point of a 60-inch chamber rather than a 46-inch one.
Why four compressors?
Volume. A five-foot-diameter chamber holds considerably more air than the smaller models, so Summit specifies four units, with four air relief valves holding the ceiling at 4.4 PSI. The redundancy benefit comes with it.
What electrical supply does it need?
A standard 120V 15 A household outlet, even with four compressors. Summit to Sea's documentation does not call for a dedicated or high-voltage circuit.
How heavy is the chamber?
Summit states approximately 50 pounds for the chamber itself.
What warranty applies?
Two years from the manufacturer. Coverage and claim procedures are set by Summit to Sea and may vary by component.
