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 should I look for when buying an outdoor spa pool?

When you start shopping for an outdoor spa pool you might be surprised at how many options you have. Choosing the right machine is a matter of considering a few key factors. Remember that this is a long-term purchase: the machine you choose now will be tasked with providing fun and relaxation for years, perhaps decades, to come. With that in mind, consider:

What is an outdoor spa pool?

Unlike an indoor spa bath, an outdoor spa pool is any spa that is designed to be installed and used outdoors. These machines, which span backyard spa pools and outdoor swim spas, are made with weather resistant materials that can withstand the sun, rain, hail and snow that the spa might be exposed to.

In Hot Spring spa pools and Endless Pools swim spas, you have outdoor spas that are built to last no matter where they might be installed, and that keep your water warmer for longer no matter the weather, thanks to ultra-efficient insulation that also keeps your power bill low.

Benefits of outdoor spa pool

Outdoor spa pools offer a wealth of benefits, particularly when compared to indoor spa baths:

  • Health and wellness: With buoyancy counteracting gravity, and with the warmth of the water stimulating a number of positive physiological responses, a spa pool is a fantastic place to find calm and comfort, stimulate movement, and even treat chronic pain.
  • A place to connect: An outdoor spa pool is a device-free zone where you can truly connect with your partner, your family and your close friends. Within the four walls of your machine you’ll find the most quality of quality time.
  • A value-adding feature: Along with the serious value an outdoor spa pool can add to your lifestyle, it also brings an X-factor that can enhance the allure and earning potential of a rental property, and that can push up the price of your home if the time comes to sell.

What size is an outdoor spa pool?

At Hot Spring we offer a complete range of outdoor spa pools. No matter how much space you have to spare, or how many people you need to squeeze in, there’ll be a Hot Spring machine to suit.

The most compact model in our range, the Freeflow Spas Mini, is built for two and measures just 183cm x 119cm x 71cm. At the other end of the Hot Spring spectrum, the Limelight Prism is a sprawling seven-seater with generous proportions of 231cm x 280cm x 97cm.

In between you’ll find a complete range of sizes, and even a number of different shapes, allowing you to pick an outdoor spa pool that perfectly fits into and ties in with your backyard. You can also place your Hot Spring under a small patio, on a deck or a balcony, or even send your outdoor spa indoors!

Key features of an outdoor spa pool

What should you look for in a backyard spa pool or an outdoor swim spa? A few of the most important and rewarding key features include:

  • Less water waste: A quality outdoor spa pool can retain its H2O for months, using water care systems to keep it clean, clear, soft and fresh. Our FreshWater Salt System, for example, can make your spa water last up to a year, all while reducing the use of chemicals.
  • Energy efficiency: Featuring powerful heaters and efficient insulation, the water in a Hot Spring outdoor spa pool is kept warm 24/7. And as NZ’s most efficient spa pool brand, this immersive warmth can cost as little as $1 per day!
  • Luxe hydromassage: At Hot Spring we are proud to sit at the leading edge of spa jet technology, having spent decades investing heavily in research and development. The result: we deliver the world’s most soothing, sumptuous hydromassage.
  • Built for fun: Interior and exterior lighting, illuminated waterfalls, optional entertainment systems; the Hot Spring patio pool and spa range is designed for a good time, and allows you to set whatever mood you like.

What are hot tub shells made from?

Hot tub shells have two main functions: to keep the water in and to keep the water warm. Shells come in a variety of materials, each with its own strengths and weaknesses:


Used in most swimming pools, vinyl’s cost-effectiveness makes it a cheaper choice for hot tubs too. It doesn’t retain heat well, nor is it particularly durable.

Rotomoulded plastic

This process sees plastic powder heated and spun in a mould. The result is lightweight, cost-effective and far more durable than vinyl.


The Rolls-Royce of hot tub plastics. Although you pay more for acrylic, you’ll enjoy a spa that is both beautiful and durable. However, it is important to note that not all acrylic hot tubs are created equal.


There’s no arguing that wood looks great, but you’ll pay for the looks with endless maintenance, both on the inside and the outside of the tub. 

Installing an outdoor spa pool

As self-contained and fully portable machines, installing a Hot Spring outdoor spa pool is a surprisingly simple task: a matter of placing the spa on a suitable surface, connecting it to power, filling it up and turning it on. Depending on the accessibility and slope of your backyard, you may need to have your spa pool dropped in via crane or HIAB, but your local Hot Spring dealer will be happy to guide you on your best installation option.

Most Hot Spring spa pools even feature Plug-N-Play technology, which means they can be plugged straight into a standard power outlet, further simplifying the installation process.

Outdoor spa pool maintenance

When it comes to spa pool maintenance, you get what you pay for. Basic machines tend to feature basic water care systems, or none at all, which makes water care and spa maintenance a time-consuming and complex task that can suck the fun out of spa pool ownership.

Hot Spring outdoor pool spas, however, boast a number of innovations that are designed to minimise the work and maximise the play of spa pool ownership, such as no-bypass filtration, easy to replace chemical cartridges, and salt and ozone systems that keep your water fresher and cleaner for longer.

When you choose a Hot Spring, you get an outdoor spa pool that offers the latest and greatest technology, unbeatable quality and energy efficiency, and the finest soaking experience on the market. If you’re after the best outdoor spa pool money can buy, one that is an investment that will pay itself back over time, look no further.

Are outdoor spa pool high maintenance?

If you choose your model wisely, your outdoor spa pool will require a surprisingly low amount of maintenance. With the help of smart tech, upkeep can be quick and easy:
