Four Things Water Does That a Gym Cannot
Aquatic therapy isn't a gentler version of land therapy. It's a different set of physics, and for some people it's the only place progress is possible at all.
It Takes the Weight Off
At waist depth you carry about half your body weight; at chest depth around a quarter; at neck depth roughly a tenth. That is how someone nine days post knee replacement can walk normally — and walking normally is what teaches the pattern back.
Book an assessmentYou Cannot Fall
Water slows every movement, so a loss of balance becomes a gentle drift rather than a fall. That means we can push balance training far harder than would ever be safe on land — which is exactly what makes it improve.
Book an assessmentResistance in Every Direction
Water resists whichever way you move, proportional to how fast you push. Every movement strengthens both sides of a joint at once, and the load self-adjusts — you simply cannot overload it by accident.
Book an assessmentWarmth and Pressure
Ninety-two degrees relaxes guarded muscle and makes stiff joints move further. Hydrostatic pressure also pushes swelling out of a limb — people frequently leave with visibly less oedema than they arrived with.
Book an assessmentWho Ends Up in the Pool
Mostly people for whom land therapy is either too painful or too slow to get started.
Seventeen Years and One Very Warm Pool
Coppervale opened on East Grant Road in 2009 around a purpose-built therapy pool — not a lap pool with a therapy hour, which is what most aquatic programmes actually are.
That distinction runs through everything. It is ninety-two degrees, which is far too warm for lap swimming and exactly right for stiff joints and guarded muscle. It is chest-deep across its whole length, so nobody is ever out of their depth. It has a submerged treadmill, an entry ramp, a lift, parallel bars and grab rails on every wall.
And a therapist is always in the water with you. Coaching from the poolside is not aquatic therapy — you cannot see what a limb is doing under the surface, and you certainly cannot put your hands on it.

- ✓Chest-deep throughout — never out of your depth
- ✓Ramp, lift, rails and a submerged treadmill
- ✓A therapist in the water with you, every session
And the Honest Answers
I Can't Swim
Neither can about half our patients. The pool is chest-deep everywhere, you can stand at every point, and your therapist is beside you the whole time. Nothing we do involves your face going near the water.
I Don't Want to Be Seen in a Swimsuit
Private changing rooms, robes at the poolside, and a session schedule that keeps the pool quiet. Plenty of people wear a t-shirt and leggings in the water and nobody minds at all.
Getting In and Out Is the Problem
There is a gently sloped ramp with a handrail, and a chair lift for anyone who needs it. Two staff assist any transfer. If you can get from a car to our front door, you can get into the pool.
Water Will Be Cold and Uncomfortable
Ninety-two degrees is warm — noticeably warmer than a swimming pool, closer to a warm bath. Most people describe the first thirty seconds as the best part of their week.
From First Call to Back on Land
Land Assessment First
Your first appointment is dry — history, movement, strength and goals, plus a proper conversation about how you feel about water. Bring a swimsuit anyway in case we go in.
Into the Pool
Two or three sessions a week, forty-five minutes, with a therapist in the water. Depth is chosen for the load you can tolerate and reduced as you get stronger.
Land Transition
The goal is always to leave the pool. Once you tolerate shallower water we run combined sessions — pool then land — so the gains transfer rather than staying wet.
Discharge or Maintenance
Most people finish. For long-term conditions like fibromyalgia or MS, ongoing pool sessions genuinely help, and we'll say so rather than pretending otherwise.
Built for Therapy, Not for Lengths
Twenty-five feet by fifteen, chest-deep throughout, and warm enough that nobody hesitates on the ramp.
What It Costs and What to Bring
Aquatic physical therapy is billed exactly like land therapy — it is physical therapy that happens in water, not a spa service. We are in-network with Blue Cross Blue Shield of Arizona, Aetna, UnitedHealthcare, Cigna, Banner and Medicare, and we verify benefits before your first visit.
Arizona has direct access, so no physician referral is needed to be evaluated. If your plan requires one for reimbursement we will tell you before you come rather than after.
Bring a swimsuit, a towel and something to walk from the changing room in. We provide everything else — flotation belts, water dumbbells, noodles and pool shoes if you'd rather not go barefoot. There are private changing rooms and hot showers.
- ✓Billed as physical therapy, not as a spa service
- ✓In-network with the major Arizona carriers and Medicare
- ✓No referral needed in Arizona
- ✓Private changing rooms, hot showers, equipment provided
What People Ask Before Their First Session
Do I need to be able to swim?
No, and roughly half of our patients can't. The pool is chest-deep at every point, you can stand throughout, and your therapist is in the water beside you. Nothing we do requires your face to go in the water or your feet to leave the floor.
How warm is it really?
Ninety-two degrees Fahrenheit, held year-round. That's several degrees warmer than a public pool and close to a warm bath. It's deliberately too warm for laps — the warmth is doing therapeutic work on guarded muscle and stiff joints.
Is it safe with an open wound or a recent scar?
Not until it's fully closed — usually around two weeks post-surgery, and we confirm with your surgeon. We'll start land-based work in the meantime and move you into the pool the moment it's appropriate.
How do I get in if I can't manage steps?
A sloped ramp with a handrail, or a chair lift, with two staff assisting. We regularly get people into the pool who use a walker or a wheelchair. If you can reach our front door we can get you in.
What should I wear?
A swimsuit, or leggings and a t-shirt if you'd be more comfortable — a lot of people do, and it makes no difference to the therapy. Private changing rooms, robes at the poolside, hot showers afterwards.
Is it covered by insurance?
Yes. Aquatic physical therapy is billed under the same codes as land-based therapy when it's medically necessary. We're in-network with the major Arizona carriers and Medicare, and we verify your benefits before you come.
Will I have to stay in the pool forever?
No — the goal is always to get you back onto land. We start combining pool and land sessions as soon as you can tolerate it. For a few long-term conditions ongoing pool work is genuinely the best option, and we'll be straight with you about which case you're in.
Come and See the Pool First
Plenty of people visit before booking anything. Have a look, put a hand in the water, ask whatever you like.
