What is a hydrotherapy spa pool?
Hot Spring's Endless Pools® hydrotherapy spas are the evolution of the hydro pool. Like a traditional hydro pool, the Endless Pools® range generates a current of water you can swim, walk or row against to recover from activity, ease chronic pain or build fitness. Where a traditional hydrotherapy pool is a big, bulky, in-ground construction that often needs its own indoor space, an Endless Pools® hydrotherapy spa is surprisingly compact and can be positioned almost anywhere.
Measuring just 3.7m to 6.1m in length depending on the model, it generates a constant current you can swim, walk, run or row against using the swim tether, built-in treadmill or resistance kit. The current can be precisely calibrated to the exact water speed you want, so it suits everyone from those rebuilding mobility to competitive athletes.

Benefits of a hydrotherapy pool
A Hot Spring Endless Pools® hydrotherapy spa is designed to support both recovery and fitness, a little like having a physiotherapy space and a personal training space in one. The benefits of warm-water therapy have been valued since ancient times. They can include supporting healthy circulation, helping to loosen tight muscles, easing swelling, and taking weight off the joints to reduce strain. The low-impact exercise a hydrotherapy pool allows can also support your cardiovascular fitness over time.
Warm, moving water offers wellbeing benefits too. Time in a hydrotherapy spa can help lower stress and encourage relaxation at the end of a demanding day.
How people use hydrotherapy
The custom-made, hydraulically powered propulsion system in our Endless Pools® swim spas creates a laminar current of up to 19,000 litres per minute. Wider than your body and deeper than your swim stroke, it delivers a smooth, consistent hydrotherapy experience.
Owners use their hydrotherapy spas to support a wide range of needs, including managing chronic pain, supporting mobility for conditions such as arthritis, aiding recovery after injury or surgery, and staying gently active where land-based exercise is difficult. Warm-water exercise can be a helpful part of a broader wellness routine, and we always recommend speaking with your doctor or physiotherapist about what is right for your circumstances.

The Lowest Running Costs, Independently Tested and Proven
A large body of water sounds expensive to keep warm, and with most swim spas it is. Hot Spring Endless Pools® swim spas are engineered to be different, holding heat where it belongs so you spend less running them and more time using them.
At the heart of that efficiency is the Tri-Thermic™ Barrier System, three factory-installed insulating layers that wrap every surface of the cabinet and base to lock heat in and keep the cold out. It is a major reason our swim spas improve energy efficiency by up to 28% over swim spas without the system, and why they meet the California Energy Commission standard, widely regarded as the toughest energy regulator in the world, alongside the APSP 14 National Standard. That certification matters because it means the efficiency is independently proven, not just claimed.

Hydrotherapy pools are clever pieces of machinery that represent a real investment in your health, wellness and lifestyle. Your primary consideration should therefore be buying from a trusted brand, ideally from a local dealership that can offer all the advice and support you might need to make the most of your pool. Other things to consider include:
While an Endless Pools swim spa is great for hydrotherapy, it can also be used to entertain, so think how many people might want to swim and soak at once.
Consider where you’ll position your compact hydrotherapy pool – inground or above-ground, indoors or outdoors – and how you’ll fill, drain and power it.
If the main objective for your purchase is hydrotherapy, look for a swim spa that offers precise control over water temperature and current speed.
By investing in quality now, you can save big money later, thanks to the enhanced energy efficiency and durability of a high-end hydrotherapy machine.

The most common reason people stop using their pool is the mental load — running costs, water care, the weather. Our Free Swim Spa Buyer's Guide shows you how to choose a system built for year-round use, backed by a 45+ year local dealer network you can trust.

Hydrotherapy pool dimensions
While compact at 2.26m wide and 3.7m to 6.1m long depending on the model, Hot Spring's Endless Pools® range is designed to feel exactly that, endless. A clever propulsion system delivers a consistent laminar current, so you never reach the end of the pool and can enjoy uninterrupted exercise. There are two main varieties of hydrotherapy exercise:
Static exercises
Warm up stretches, arm movements, leg raises, core exercises.
Moving exercises
Swimming, paddling, kicking, walking, jogging, rowing.
Hydrotherapy pool design
Innovating for four decades, Hot Spring stays on the leading edge of hydrotherapy design. Our swim spas are built around a hydraulic propulsion system that generates a steady, precisely controlled current to move against, the core of the hydrotherapy experience.
On dual-zone models, the separate spa side adds a dedicated recovery space. Here you will find our hydromassage seating, including the Moto-Massage® DX jet, which sends two strong streams of water sweeping up and down the length of your back to help relieve tension and support relaxation after exercise.

What is the temperature of a hydrotherapy pool?
Every Hot Spring hydrotherapy spa can be set to your ideal temperature through an easy-to-use control panel. The market-leading insulation in our swim spas also holds that heat efficiently, resulting in far lower power bills than comparable models from other brands.
Hydrotherapy is most commonly performed in water around 34°C, warm enough to realise the benefits of warm-water therapy without being too hot. The right temperature is a matter of personal preference, so we suggest starting at 34°C and adjusting from there.
Want to train cool and recover warm? Dual-zone models like the E2000 and X2000 give you two separate bodies of water with independent temperature control. Keep the swim side cool for vigorous exercise and the spa side hot for hydrotherapy and recovery, and enjoy both in a single session, any day of the year.
Where is the best hydrotherapy pool placement
If you have invested in a backyard hydrotherapy pool for health and wellness, placement matters. First you will need a spot with enough room, which the compact footprint of an Endless Pools® swim spa can make surprisingly easy. An outdoor installation is the most common option, though you can also install indoors if you have a suitable, well-ventilated space.
For many people the best option is an in-ground installation. This can make it far easier to get in and out of the pool, which is ideal for anyone using hydrotherapy to build or maintain mobility, recover from injury or manage chronic pain.
Are hydrotherapy pools high maintenance?
When you choose an Endless Pools® swim spa, your hydrotherapy pool will not require much work at all.
As little as five minutes per month with Hot Spring technologies.
As little as once every four months with Hot Spring technologies.
As little as once a year with Hot Spring technologies.

We have had our new Hot Springs spa pool for 10 months and we are very pleased with the pool and the service. Very knowledgeable and efficient team, worked extra hard to get it installed at a very busy time of year, and they have been a great source of information and advice on maintenance and new products.

Since buying my Gleam spa pool in 2017, Hot Spring Spa Pools have been absolutely amazing and dedicated to helping.
Being new to salt water spas, Hot Springs sent someone to assist in checking my water and this was a year after I had brought it.
They’ve also assisted in moving the spa 6 years after purchase and expected nothing in return. Absolutely fantastic service!!!

Absolutely love my pool and it is easier than I thought to maintain it. Would recommend to friends without hesitation.

Are hydrotherapy pools good for your health?
Warm-water exercise can support the body in a number of ways, from easing everyday aches to helping you stay mobile and active:
The combination of aquacise and warm water immersion gets your heart sending more oxygen- and nutrient-blood to where it’s needed.
Hydrotherapy pools enhance muscle strength and tone, and the spa pool section of your swim spa can help to reduce inflammation and lactic acid build-up.
Between the buoyancy and the warmth of the water, joints can move more easily, enhancing movement in those with limited mobility.
Lean back into the hydromassage jets of your Endless Pools swim spa and enjoy the ultimate in backyard relaxation.
