Summit to Sea Grand Dive Hyperbaric Chamber
The Grand Dive is the large-format lying chamber in Summit to Sea's current range — 40 inches in diameter, operating at 1.3 ATA (4.4 PSI). It uses the same high-efficiency compressors with patented sound suppression and in-line air filtration as the Shallow Dive and the Dive, in a substantially wider chamber.
Wellari Expert Take
Who the Grand Dive Suits
Chamber choice in the Summit to Sea range comes down to internal space, 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 and orientation.
At 40 inches in diameter the Grand Dive is a significant step up in width from the Dive's 33 inches. That is the measurement that decides whether a chamber feels like a tube or like a space you can settle into, and it is the reason people move up the range rather than down it.
Width is what you are buying here. If the Dive is close but feels tight, the Grand Dive is the next step. If floor area is your constraint rather than comfort, the Dive or Shallow Dive will fit a room the Grand Dive will not.
Best For
- Buyers who found the 33-inch Dive too narrow and want meaningfully more interior width
- Rooms that can take a 40-inch diameter with clear working space on the entry side
- Larger users, or anyone who wants to change position during a session
- Settings where a roomier chamber is worth more than the smallest possible footprint
- Buyers who want to stay within Summit's 1.3 ATA range at a larger size
Grand Dive Features & Buying Details
Pressure & Performance
- Operating pressure: 1.3 ATA (4.4 PSI)
- Compressors: the same high-efficiency electric compressors used in the Shallow Dive and the Dive
- Air handling: patented sound suppression, plus in-line air filtration
Summit to Sea states directly that the Shallow Dive, the Dive and the Grand Dive share the same high-efficiency compressors with patented sound suppression and in-line air filtration. That is a useful thing to know when stepping up in chamber size — the acoustic character of the system does not change with the chamber.
What we are not stating here. Summit publishes a detailed feature list for several chambers in the range but not for the Grand Dive. We are therefore not publishing a compressor count, valve count or window count for this model. Ask us and we will obtain the current figures from Summit to Sea in writing before you order.
Size & Fit
- Diameter: 40 inches
- Orientation: lying
On the chamber length. Current published sources give different figures for the Grand Dive's length, so it is not stated here. Diameter is consistent across sources at 40 inches and is the measurement that usually decides fit. If length is critical to your room, contact us and we will confirm the current figure with Summit to Sea in writing before you order.
Plan for the chamber footprint plus clear working room on the entry side, and a position for the compressors within reach of an outlet.
Installation & Electrical
Site the chamber on a level floor with clear access on the entry side and room around it for airflow and for the compressors.
Electrical requirement. Contact us and we will confirm the current electrical requirement for this chamber with Summit to Sea in writing before you order.
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
Ask us before you order and we will confirm in writing exactly what ships with this chamber — frame, mat, case, hoses and any accessories — so there is no ambiguity about what arrives.
Warranty & Support
- Manufacturer warranty: 2 years
- Brand: Summit to Sea
- Model: Grand Dive
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.
