Soft-Shell vs Hard-Shell Hyperbaric Chambers: What’s the Difference?
If you're comparing hyperbaric chambers, one of the first decisions is whether you need a soft-shell or hard-shell system.
They differ in construction, pressure capability, footprint, cost, installation and how they are commonly used.
The right choice is not simply the chamber with the highest ATA. It is the chamber that best fits how, where and how often you plan to use HBOT.
Start With the Basics
What Actually Makes a Chamber Soft-Shell or Hard-Shell?
The distinction begins with the chamber itself.
A soft-shell chamber uses a flexible chamber body that pressurises when in use. ReWell's current rental range operates at 1.5 ATA and includes lying, seated and wider-entry accessible options.
A hard-shell chamber uses a rigid chamber body and can support higher operating pressures depending on the model. ReWell's core hard-shell rental range includes 2.0 ATA and 2.5 ATA systems.
That difference in construction influences not only pressure, but also installation, space, cost, intended setting and operating requirements.
The Two Main Categories
Soft-Shell vs Hard-Shell at a Glance
Flexible Home Access
Soft-Shell Chambers
ReWell Rental Range · 1.5 ATA
Soft-shell chambers are generally the most accessible route into regular home HBOT and are easier to place within a domestic environment.
- Flexible chamber body
- 1.5 ATA across ReWell's current rental range
- Lying, seated and accessible designs
- Lower rental entry point
- 1, 2 and 3-month rental options
- Suitable for regular home use
Higher-Pressure Systems
Hard-Shell Chambers
ReWell Rental Range · 2.0 & 2.5 ATA
Hard-shell chambers use a rigid structure and are designed for higher-pressure, professional or more permanent applications.
- Rigid chamber construction
- Higher-pressure capability
- 2.0 and 2.5 ATA rental options
- Slimline, lying and seated configurations
- Professional installation requirements
- Often considered for clinics and facilities
Soft-Shell
Why People Choose a Soft-Shell Chamber
For many private users, soft-shell is the most practical place to start.
ReWell's soft-shell rental range is designed for regular use at home, with flexible rental periods and three different configurations depending on space and accessibility.
It also gives people a way to experience the reality of repeated home HBOT before making a larger commitment to ownership.
ReWell's soft-shell rental range includes lying, seated and accessible 1.5 ATA chambers.
Hard-Shell
When a Hard-Shell Chamber May Make More Sense
Hard-shell systems become more relevant when the intended use requires a different pressure range, more permanent installation or a professional facility setting.
ReWell's hard-shell rental range currently includes 2 ATA and 2.5 ATA lying, slimline and seated configurations, with a six-month minimum term.
They are commonly considered by clinics, sports and recovery facilities, longevity and wellness settings, hospitality environments and suitable private users.

Pressure Matters
But ATA Shouldn't Be the Only Number You Look At
Chamber pressure is important because HBOT protocols use different pressure levels depending on the setting and purpose.
But comparing chambers purely by ATA can be misleading.
The decision also depends on oxygen delivery, chamber design, intended use, session frequency, installation, operating requirements, budget and training.
ReWell's current 2.5 ATA hard-shell systems require operational training. The advertised 2.0 ATA systems do not require the same training.
Higher pressure is not automatically better. The right pressure is the one that makes sense for the intended use and the person or facility using it.
Side-by-Side Comparison
Soft-Shell vs Hard-Shell Hyperbaric Chambers
| Feature | Soft-Shell | Hard-Shell |
|---|---|---|
| Construction | Flexible pressurised chamber body | Rigid chamber body |
| ReWell rental pressure | 1.5 ATA | 2.0 ATA or 2.5 ATA |
| Rental from | €1,229/month | €1,999/month |
| Rental term | 1, 2 or 3 months | 6-month minimum |
| Available formats | Lying, seated, accessible | Lying, slimline, seated capsule |
| Typical setting | Home and suitable clinic use | Professional facilities, longer-term use and suitable private settings |
| Training | Operating and safe-use guidance | Training required for current 2.5 ATA systems |
| Installation | Professional delivery and setup | Professional installation, with more site-specific requirements |
| Ownership | Available | Available across multiple hard-shell configurations |
Cost
How Do Soft-Shell and Hard-Shell Costs Compare?
Cost is one of the clearest differences between the two categories.
ReWell's soft-shell rental range begins at €1,229, while hard-shell rental starts from €1,999 per month.
Ownership costs vary significantly depending on chamber type, pressure and configuration.
ReWell also sells soft-shell chambers and a broader range of hard-shell systems, so the final purchase price depends on the exact model selected.
Up to six months of eligible rental payments may also be credited towards a future chamber purchase.
Which One Is Right for You?
Start With the Use Case — Not the Chamber
The simplest way to make this decision is to start with how the chamber will actually be used.
Soft-Shell May Suit You If...
You want flexible home access, are new to regular HBOT, prefer a lower entry cost, want shorter rental periods or want to experience regular chamber use before buying.
Hard-Shell May Suit You If...
You are operating a clinic or facility, need higher-pressure capability, want a more permanent installation or have specific professional or long-term requirements.
Some people arrive assuming they need the highest-pressure chamber available. Others assume a soft-shell chamber is automatically enough.
Neither assumption is particularly useful.
Define the intended use first. Then choose the chamber that fits it.

Specialist Guidance
Still Not Sure Which Chamber Makes Sense?
ReWell's HBOT programmes are guided by Davitt Meenaghan, IBUM-certified Hyperbaric Safety Officer.
“The right question isn't ‘Which chamber is better?’ It's ‘What are you using it for, where is it going and what level of access do you actually need?’”
Davitt can help you compare chamber type, pressure, space, installation, rental duration, purchase options and the practical differences between soft-shell and hard-shell HBOT.

Soft-Shell vs Hard-Shell Chamber FAQs
What is the main difference between a soft-shell and hard-shell hyperbaric chamber?
Soft-shell chambers use a flexible chamber body and typically operate at lower pressure. Hard-shell chambers use a rigid structure and can support higher operating pressures depending on the model.
What pressure are ReWell soft-shell chambers?
ReWell's current soft-shell rental range operates at 1.5 ATA and includes lying, seated and accessible configurations.
What pressure are ReWell hard-shell chambers?
ReWell's core hard-shell rental range includes 2.0 ATA and 2.5 ATA systems. The broader sales range also includes additional configurations depending on the model.
Is a hard-shell chamber better than a soft-shell chamber?
Not automatically. The right chamber depends on the intended use, pressure requirements, location, installation, frequency, budget and individual circumstances.
Do 2.5 ATA chambers require training?
Yes. ReWell's currently advertised 2.5 ATA hard-shell systems require operational training. The current 2.0 ATA models do not require the same training.
Can I rent before buying?
Yes. ReWell offers both soft-shell and hard-shell rental. Up to six months of eligible rental payments can be credited towards a future chamber purchase.
Which chamber is more suitable for home use?
Soft-shell chambers are generally the more flexible route for home use because of their footprint, price and shorter rental periods. Some hard-shell systems may also suit private use where space, installation and pressure requirements make them appropriate.
Choose Based on Use — Not Hype
Find the Chamber That Actually Fits

This guide is for general educational purposes. HBOT may not be suitable for everyone and individual screening and suitability matter before use. Chamber specifications, pressure, pricing, availability and training requirements should be confirmed with ReWell before renting or purchasing.
