Shipping to Alaska, Hawaii or a US territory?
Yes, we ship there. Freight to these addresses is quoted per order rather than charged at checkout — so no shipping option will appear online and the order cannot be completed by itself. That is deliberate, and it is not a decline.
- InfraCore covers the continental US freight on every product.
- We request the actual freight quote from the manufacturer for your address.
- You pay only the amount above the continental US rate.
- You receive one emailed invoice covering the equipment plus that additional freight, so you have the complete total before the order is placed.
Nothing is charged and no order is placed until you have seen that total and approved it.

Federal law requires hyperbaric chambers to be sold by or on the order of a licensed physician. A copy of your prescription must be provided prior to order fulfillment. Contact us with questions — we make this simple.
Two of you. Same session. Same morning.
The Grand Dive is the chamber for households where two adults will actually use it together. A 40-inch interior — seven inches wider than the standard Dive — opens up real room for two recliners, or one person with serious shoulder space. It's the same FDA-cleared 1.3 ATA mild hyperbaric platform, scaled up just enough to change who can use it.
Small clinical practices reach for the Grand Dive for the same reason: it gives you the flexibility to run a single full-comfort patient session or a couples session, without locking in either configuration.
Who this is for
- Couples who want to start the morning or end the evening with a shared session.
- Families with two adults committed to hyperbaric as a long-term wellness practice.
- Small clinical practices that occasionally need to seat two people together.
- Single users who simply want the most generous interior in a horizontal chamber.
- Anyone whose harder-living years are catching up and who'd rather not negotiate their next twenty-five for them.
Who it's not for
- Single daily users where the extra space won't get used — the Dive is more efficient at $4,000 less.
- Compact installs — the 40" × 90" footprint is real and the chamber needs surrounding clearance.
- Rehab and accessibility-needed setups requiring wheelchair or gurney access — see the Grand Dive Pro Plus.
- Entry without assistance, for a non-ambulatory user. Summit to Sea notes the Grand Dive's end entry works well in this situation, but a patient lift (hoyer lift) would be needed — one is not included and we do not supply one. If entry without transferring the user matters, the Grand Dive Pro Plus is the chamber that does it.
- Anyone who can't or won't obtain a physician's prescription.
What you get
- An FDA 510(k)-cleared Class II medical device — clearance K072757, cleared for the treatment of acute altitude sickness — manufactured in the USA by Summit to Sea (30+ years building hyperbaric chambers).
- A 40-inch interior diameter and 90-inch length — room for two adults in recliners or one user with generous shoulder space.
- Dual oil-less compressors with Summit to Sea's patented sound-suppression housing — quiet enough for a bedroom install.
- Three pressure-relief valves (2 blue + 1 yellow backup) and a failed-circuit alarm.
- Double-sided full-length zippers, operable from inside and outside, with silicone lubrication included.
- A standard 120V 15-amp outlet — no special wiring, no electrician, no permits in standard residential setups.
- 7-day-a-week customer support through InfraCore's concierge line, routed directly to Summit to Sea's US technical team.
- The same 1.3 ATA mild HBOT protocol used by every other Summit to Sea chamber — same therapy, more room.

How it compares
The Grand Dive is our pick for couples and small clinical practices — the right chamber when one adult isn't the whole story. Here's how to think about it:
vs. Dive — The standard Dive is a 33-inch single-user chamber. The Grand Dive adds seven inches of width and supports 2–3 people. Choose the Dive for solo daily use; choose the Grand Dive if a partner, spouse, or patient will share sessions or want more room.
vs. Grand Dive Vertical — The Grand Dive Vertical is the same 60-inch class but seated — different ergonomics, same intent. Choose the Grand Dive if you want to lie down; the Grand Dive Vertical if floor space is tight or seated sessions fit your routine.
vs. Grand Dive Pro — The Grand Dive Pro adds six inches of interior width (46 inches vs 40) and a third pressure-relief valve. Neither chamber supports wheelchair or gurney entry — for that, see the Grand Dive Pro Plus. Choose the Pro for rehab or accessibility needs; the Grand Dive is the better-value choice for non-clinical shared use.
vs. clinic HBOT (commercial wellness) — Commercial HBOT clinics charge $150–$250 a session. At three sessions a week for two adults, the Grand Dive pays itself back in roughly 5–7 months. After that, every session is essentially free for both users.
Your protection & logistics
Warranty
Summit to Sea warrants your chamber against defect for two years from delivery, covering parts and labor on every component — zippers, windows, seams, valves and hoses included. Repair or replacement is at Summit to Sea's option, and this warranty is in lieu of all other warranties. Misuse and unauthorized modification are not covered, and shipping to and from Summit to Sea on a warranty claim is the customer's responsibility. Extended 1, 2, and 3-year warranty options can be purchased any time within the two-year period — your Wellness Concierge will quote the exact figure for your chamber. All FDA-cleared chambers, manufactured in the United States.
Shipping & lead time
Freight to the 48 contiguous states is included in the price. Summit to Sea holds chambers in stock rather than building to order; we place your order with them once your payment has settled, and they typically ship within 24–48 hours of receiving it, by FedEx with tracking; transit time depends on your destination, and the carrier's window is an estimate rather than a guarantee. Alaska and Hawaii are quoted per order — we request the freight quote from Summit to Sea and confirm the cost with you before you commit to anything. Professional on-site installation is available for a nominal charge through Summit to Sea's own installer, who schedules the appointment directly with you — your Wellness Concierge quotes it before you order.
Installation
Self-install with full setup documentation. Every Summit to Sea chamber ships with operator instructions, and your Wellness Concierge schedules a 30-minute setup call to walk through first-use safety, oxygen-concentrator pairing, and session protocol. On-site installation services can be arranged on request.
Returns
You may return your chamber within 15 days of delivery in its original condition; return shipping is the customer's responsibility and the original shipping charge is deducted from the refund — full terms are set out under Returns below. If a chamber arrives damaged or with a manufacturer defect, the Summit to Sea warranty handles replacement and we manage the claim.

Frequently asked questions
Do I really need a prescription?
Yes — hyperbaric chambers are FDA-cleared Class II medical devices, and federal law requires a physician's prescription. We've made this easy: send us a prescription from your primary care, sports-medicine, or functional-medicine provider, and we coordinate the rest. Most clients have one in hand within a week.
What does "mild hyperbaric" mean, and what is it good for?
Summit to Sea chambers operate at 1.3 ATA (4.4 PSI) — the soft-chamber range FDA-cleared for home use. That's different from the 2.0–2.4 ATA hospital HBOT used for acute medical emergencies. Mild HBOT is what athletes, biohackers, and longevity-focused users build into their week for recovery, sleep quality, post-surgical healing, post-concussion support, and general resilience.
How does owning compare to clinic HBOT visits?
Clinic HBOT runs $150–$250 per session, typically 60–90 minutes plus travel and scheduling. At three sessions a week, you're at $23K–$39K a year — and you're still on someone else's calendar. The Grand Dive pays itself back in roughly 10–15 months at that cadence, and most home users do more sessions because access is frictionless.
How does it compare to a hospital hyperbaric chamber?
Different tool, different job. Hospital chambers are hard-shell, pressurized to 2.0–2.4 ATA, run by trained staff, and used for acute conditions (carbon-monoxide poisoning, decompression sickness, non-healing wounds). Summit to Sea chambers are FDA-cleared for the soft-chamber 1.3 ATA range — the therapeutic window appropriate for daily at-home and clinical wellness use without medical staff present.
Can two adults actually fit comfortably?
Yes. The 40-inch interior accommodates two reclining adults side-by-side, or two seated upright with a small table between you. Couples typically use the chamber for morning recovery sessions; small clinics use it for paired patient sessions or single-patient comfort. There's no ergonomic compromise compared to two separate chambers — the experience inside is shared and quiet.
How loud is it?
Summit to Sea uses oil-less compressors with patented sound-suppression housing. Operating volume is comparable to a quiet dishwasher (~50 dB at six feet). Most clients run sessions in a dedicated wellness room, but bedroom installs are common — you can sleep next to it.
How long does each session actually take?
Plan on 75–105 minutes door-to-door for a 60-minute therapy session: 5–10 minutes to pressurize, 60 minutes at depth, 5–10 minutes to depressurize, plus a few minutes to set up and break down. Easy to fit into a morning routine, evening wind-down, or a working session — you can read, work on a laptop, or sleep inside.
How long does delivery and setup take?
Summit to Sea holds these chambers in stock rather than building each one to order. We place your order with them once your payment has settled, and they typically ship within 24–48 hours of receiving it. Transit time then depends on where you are: your chamber travels by FedEx freight with tracking, and the carrier's delivery window is an estimate rather than a guarantee. In the rare case a model is not in stock, Summit to Sea manufactures on a monthly schedule and your Wellness Concierge confirms the ship window before you pay. First-time setup runs about 60 minutes (frame and compressors); after that, breakdown and re-setup runs around 15 minutes. Our concierge team coordinates everything; if you'd like white-glove setup assistance, just ask.
What's the warranty?
Two full years on parts, labor, zippers, windows, seams, valves, and hoses — well above the 1-year industry norm. Extended warranties are available for purchase at any time during the original warranty period. All service routes through Summit to Sea's US technical team via our concierge line — one point of contact.
From the founder
I built InfraCore because I needed it.
Two devastating knee injuries and multiple ankle injuries before I left high school gave me twenty-five years of compounding consequences — chronic pain, multiple surgeries, mobility I was working hard to keep. The clinic visits worked. They just didn't fit a real life.
When my husband and I start building our own wellness room, the Grand Dive is the chamber I'm putting on the long-list — same therapy as the Dive, but room for two of us to share a session. If you're building this kind of room for someone you love, this is the chamber that makes it a shared practice.
