The Lowest Running Costs, Independently Tested and Proven

The cost of running a spa pool can be significant… unless you choose Hot Spring. We offer New Zealand’s most energy efficient spa pools, with running costs as little as $1 a day. This is a luxurious soak that won’t cost the earth.

How can such luxury come so cheap? Our insulation is carefully designed for maximum heat retention. Our covers are fully insulated and precisely engineered to form a perfect seal around the lip of your spa.

Then there’s our suite of technological innovations, from heat induction jets that recycle the warmth generated by the internal machinery, to our SilentFlo 5000 circulation system that keeps your water moving while using the same amount of power as a 40-watt light bulb.

What is a hydrotherapy spa pool?

Hot Spring’s Fastlane Pools hydrotherapy spas are the evolution of hydro pools. Like a normal hydro pool, the Fastlane Pools range generates a current of water you can swim, walk or row against in order to recover from activity, treat chronic pain or enhance your fitness. Where a traditional hydrotherapy spa pool is a big, bulky, in-ground construction that often demands its own indoor space, an Fastlane Pool is surprisingly compact, incredibly cost effective, and can be positioned almost anywhere.

Measuring just 3.7m – 6.1m in length depending on the model, an Fastlane Pools hydrotherapy spa generates a constant current of water that 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 deliver the exact water speed you want, meaning our Fastlane Pools are perfect for everyone, from the elderly to Olympic athletes!

Benefits of a hydrotherapy pool

As a Hot Spring Fastlane Pools hydrotherapy spa delivers both remedial and fitness benefits, you have a physiotherapist and a personal trainer all in one. The benefits of hydrotherapy have been known since ancient times. The benefits include the stimulation of circulation to deliver nutrient-rich blood to the body, the loosening of tight muscles, the reduction of swelling, and taking of the weight off your joints to reduce wear and pain. The fitness that can be gained from a hydro pool can do wonders for your cardiovascular system.

Our hydro pools also offer tangible mental health benefits. The ambience of a spa pool has been proven to help your mental state by lowering stress and promoting relaxation.

What conditions are treated with hydrotherapy?

The custom-made, hydraulically powered propulsion system of our Fastlane Pools creates a laminar current of up to 19,000 litres per minute. Wider than your body and deeper than your swim stroke, this current offers the most reliable and effective hydrotherapy experience on the market.

Fastlane Pools customers use their hydro pools for a wealth of conditions, including chronic pain, Parkinson’s, musculoskeletal conditions like arthritis and fibromyalgia, neurological conditions, muscle spasms, cardiovascular and heart conditions, injury and surgery recovery and even paediatric conditions of young ones.

What should I look for when buying a hydrotherapy pool?

When shopping for a new spa pool, your first focus should be on quality. When you buy from an established name, particularly one with a local presence, you can be more confident that your spa pool will last and that you’ll enjoy all the support you need to get maximum value and enjoyment from your purchase. Other considerations include:

Hydrotherapy pool dimensions

While compact (2.26m wide and 3.7m – 6.1m long, depending on the model), Hot Spring’s Fastlane Pools range is designed to be endless. Through a clever propulsion system we deliver a consistent laminar current that will ensure you never hit the end of the pool, letting you 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

Bubbling with innovation for four decades, at Hot Spring we remain on the leading edge of spa and hydro pool design. Our hydro pools are designed for the ultimate hydrotherapy experience, whether that’s delivered by our revolutionary moving massage jets while you sit, or by our hydraulic propulsion system that generates a steady current to move against.

Our hydrotherapy seating is where we made our name. Our Moto-Massage DX jet has revolutionised hydrotherapy, producing two strong streams of water that sweep up and down the length of your back, relieving aches and muscle tension while promoting wellness and relaxation.

What is the temperature of a hydrotherapy pool?

All Hot Spring hydro pools can be precisely calibrated to your ideal temperature via an easy to use control panel – just choose a number and the spa pool will do the rest! The market leading insulation used in Hot Spring spa pools also ensures that heat is efficiently retained, resulting in far lower power bills than similar models from other brands.

Hydrotherapy is most commonly performed in 34°C water, as this temperature ensures that all of the benefits of warm water therapies are realised, without the water being too hot. However, the perfect temperature for you will be a matter of personal preference. We recommend starting at 34C and adjusting up or down from there.

More of a warm blooded creature? Our CoolZone System grants you the ability to cool your spa’s water as well as warm it. Using CoolZone you can enjoy the perfect spa temperature and the benefits of hydrotherapy all year round, regardless of what the weather might be doing.

Best hydrotherapy pool placement

If you have invested in a backyard hydrotherapy pool for health and wellness reasons, the placement of the machine becomes all the more important. Firstly you'll need to find a spot with enough room, which the compact footprint of a Fastlane Pools swim spa can make surprisingly easy. A hydrotherapy outdoor spa is the most common option, although you can also install a hydrotherapy indoor spa pool if you have the necessary space in a well-ventilated room.

Arguably the best option, however, is a hydrotherapy inground spa configuration. This can make it far easier to get in and out of the pool, which is ideal for anyone using hydrotherapy to regain or maintain mobility, recover from injury or manage chronic pain.
