Summit to Sea Grand Dive Pro Hyperbaric Chamber
The Grand Dive Pro is the large-entry chamber in Summit to Sea's current range — 46 inches in diameter and 8 feet long, operating at 1.3 ATA (4.4 PSI). Its defining feature is the entrance: a circumferential opening wide enough to admit a stretcher, with double-sided zippers that work from inside or outside. It runs from a standard 120V 15 A household outlet.
Wellari Expert Take
Who the Grand Dive Pro 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.
Access is what separates the Pro. At 46 inches in diameter it is wider than the Grand Dive, but the more consequential difference is the entrance: Summit designs it with a large opening and circumferential zippers, wide enough that a stretcher can be brought in. That matters for anyone who cannot climb into a side-entry chamber unaided — and it is why this model appears in practitioner settings rather than only in spare bedrooms.
The stretcher is not included, and Summit does not sell one. If stretcher access is the reason you are looking at this chamber, budget for that separately and confirm the dimensions of the stretcher you intend to use.
Best For
- Users who cannot easily climb into a conventional side-entry chamber
- Practitioner and clinic settings where assisted entry matters
- Buyers who want more width than the 40-inch Grand Dive
- Installations where a stretcher may need to be brought into the chamber
- Anyone who wants large-format access without a dedicated electrical circuit
Grand Dive Pro Features & Buying Details
Pressure & Performance
- Operating pressure: 1.3 ATA (4.4 PSI)
- Pressure control: double vent system, for safely achieving a maximum of 4.4 PSI
- Auxiliary valve: one
- Compressors: two high-efficiency electric compressors, run in redundancy
- Air handling: patented sound suppression, plus in-line air filtration
Why there are two compressors. The second unit is redundancy, not extra output — a single compressor fault does not end a session abruptly.
The double vent system is the pressure ceiling. It holds the chamber at a maximum of 4.4 PSI rather than relying on the operator to manage it.
Size, Access & Interior
- Diameter: 46 inches
- Length: 8 feet
- Viewing windows: two large windows
- Entry: large opening with double-sided circumferential zippers, operable from inside or outside
- Stretcher access: the opening is large enough to admit a stretcher. A stretcher is not included and is not sold by Summit to Sea.
- Chamber weight: approximately 55 lb
Circumferential zippers are the difference. Rather than a zip along one side, the opening runs around the chamber, which is what allows a genuinely wide entrance rather than a slot. It still works from inside or outside.
At approximately 55 lb the chamber is movable by two people once deflated, so the installed position is not permanent.
Electrical & Installation
- Supply: standard 120V 15 A outlet
- Frame: external furniture-grade PVC frame, included
- Siting: level floor, with clear working room around the entry
Summit to Sea specifies that this chamber works on an ordinary 120V 15 A household circuit. No dedicated or high-voltage supply is called for in the manufacturer's documentation. Position it so both compressors reach an outlet without an extension run, and allow generous clear floor space at the entrance — the wide opening is only useful if you can get to it.
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

On the elevated platform. Summit's current materials are inconsistent about whether a platform ships with this chamber — its feature list mentions one, while its pricing distinguishes a with-platform and a without-platform configuration. We are not stating either way. Contact us before ordering and we will confirm in writing which configuration you would receive.
A stretcher is not included and is not sold by Summit to Sea.
Warranty & Support
- Manufacturer warranty: 2 years
- Brand: Summit to Sea
- Model: Grand Dive Pro
- Patent: US 11,452,654 B2
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.
What pressure does it run at?
1.3 ATA, which is 4.4 PSI. A double vent system holds the chamber to a maximum of 4.4 PSI. Every chamber in Summit to Sea's current range runs at this same pressure.
What makes the Pro different from the Grand Dive?
Width and access. The Pro is 46 inches in diameter against the Grand Dive's 40, and its entrance uses circumferential zippers to create an opening wide enough for a stretcher rather than a side entry.
Is a stretcher included?
No. The opening is sized to admit one, but a stretcher is not included and Summit to Sea does not sell one. Confirm the dimensions of any stretcher you intend to use.
Does it come with an elevated platform?
We are not stating either way. Summit's current materials are inconsistent — the feature list mentions a platform while the pricing distinguishes with-platform and without-platform configurations. Contact us and we will confirm in writing which configuration you would receive before you order.
What electrical supply does it need?
A standard 120V 15 A household outlet. Summit to Sea's documentation does not call for a dedicated or high-voltage circuit. Avoid running it on an extension cord.
How heavy is the chamber?
Summit states approximately 55 pounds for the chamber itself, so it remains movable by two people once deflated.
What warranty applies?
Two years from the manufacturer. Coverage and claim procedures are set by Summit to Sea and may vary by component.

Where Summit's own materials contradict each other, as they currently do on the platform, we confirm the answer in writing before you order. We also handle the prescription requirement as a documented step in our order process rather than leaving it to you to discover after purchase. Products are sourced through verified manufacturer, distributor or supplier channels.
Need the platform configuration confirmed?
Tell us your room, who will be using the chamber and whether stretcher access matters. We will confirm the platform configuration with Summit to Sea in writing, and walk you through the prescription step, before you order.
