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 dual zone spa?

Dual zone spas are the all-rounder of the spa world. Offering hydrotherapy, fitness, fun and relaxation in equal measure, they represent the ultimate in personal spa technology, and are becoming increasingly popular amongst those who seek the ultimate backyard spa experience.

True to their name, dual zone spas feature two separate pools, one designed for relaxation, the other for movement. At one end you have a four-seat hot tub section, complete with hydromassage jets. At the other end you have a 4.5m fitness pool. This offers a full-body workout, featuring swim-in-place technology, plus optional treadmill, aqua bike, rowing and swim tether features. You can enjoy the ultimate water-based workout, then help your body recover with a perfectly soothing post-exercise hydromassage in the adjacent spa section.

Dual zone spas feature independent temperature control allowing you to enjoy a warm workout in the swim pool and a relaxing spa in the hot tub, or vice versa. The four-seat arrangement on the hot tub side is as good for play as it is for work, with optional Bluetooth speaker system and WiFi connectivity making time with friends and family that much more enjoyable.

Combining feature-heavy (and energy efficient) function with contemporary design form, a dual zone spa is the ultimate showpiece of a modern backyard.

Dual zone spas vs. pool spa combos

In the past, combining the fitness and recreation of a pool with the relaxation and fun of a spa has meant purchasing a pool and spa combo. Dual zone spas are beginning to change that, however, and for a few good reasons:

  • Cost: While the price of a pool and spa combo can at first appear lower than a dual zone spa, this quote doesn’t take into account the endless additional costs, including engineering reports, stabilising the foundation, council consents, excavation, landfill removal, large water quality and heating systems, covers, landscaping, planting, pool fencing and more. By contrast, the additional costs involved with your dual zone spa are minimal.
  • Space: Pool and spa combos require a big backyard. Dual zone spas pack more features into a far smaller unit.
  • Use: Unless you’re prepared to pay sky-high power bills, pool and spa combos can only really be used during the warmer months. Energy efficient dual zone spas can be used all year round. 
  • Maintenance: Ask any pool owner about maintenance and you’re likely to get a roll of the eyes. The fact is that larger bodies of water are more work to maintain. Dual zone spas, that have covers, demand far less attention.

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. 

Dual zone swim spa dimensions?

At once compact and roomy, a dual zone spa can feel far larger than its footprint actually measures. Hot Spring’s two dual zone spas, the E2000 Endless Pool Fitness System & Spa, and the X2000 SwimCross Exercise System, both measure 610cm (L) x 226cm (W) x 147cm (H), and have a maximum filled weight (including water and 10x 80kg adults) of 11,255kg.

When considering whether a dual zone spa will fit in your space, you should ask yourself the following questions:

  • Is the surface strong and level? Given the weight, a solid foundation is a must. If you plan to install your dual zone spa on a deck, particularly one that’s elevated, get a professional to check its maximum load capacity. The deck  must also be level and even. 
  • Is there enough space around the spa? Not just to comfortably get in and out, but for maintenance and optional extras like steps and decking too.
  • Is there a sufficient power source nearby? A dual zone spa requires a 220V-240V, 32A power source as a minimum to run.

How much do dual zone spas cost?

To guard yourself against cheap and potentially dangerous products, check that your dual zone spa meets ISO:9001 standards.

How energy efficient are dual zone spas?

In the past the words ‘spa’ and ‘energy efficiency’ haven’t often appeared in the same sentence. Thanks to advances in design, a modern, high quality, dual zone spa can be surprisingly efficient although the amount of energy you use will depend how often you use it.

Hot Spring dual zone spas feature the Tri-Thermic™ Barrier System, which provides three layers of insulation that conserve heat, enhance the energy efficiency and lower running costs.

The system includes a lightweight 2cm layer of expanded polystyrene foam, a reflective film attached to the inside of the cabinet, and a 5cm thick heat retention layer made of high-quality recycled fibres and foil film. The result is maximum thermal performance.

There are a number of ways you can help your Hot Springs spa to do its job even more efficiently:

  • Invest in an insulated cover
  • Minimise the use of jets in winter
  • Utilise a solar power setup
  • Commit to a regular water maintenance schedule

Best dual zone spa placement

Where should you place your dual zone swim spa? When you choose a self-contained and fully portable Endless Pools swim spa, you aren't short of options (as long as you have the necessary space, and access to the water, power and drainage you need). You can install a dual zone outdoor spa pool on earth, pavers or even a sturdy deck. You can install a dual zone indoor spa pool in a sun room or any other enclosed, well-ventilated area.

You can even install a dual zone inground spa pool, excavating a patch of your backyard and dropping the swim spa in. This can make your Endless Pools machine feel even more like a permanent swimming pool - only one that is always the ideal temperature, and that you'll never reach the end of!

Are dual zone swim spas high maintenance?

When you choose wisely, no, a dual zone spa is not high maintenance, particularly if you choose the right water care system.
