If you are considering investing in a wellness retreat for your backyard, you have likely encountered the rising popularity of hydrotherapy and its remarkable health benefits. This comprehensive guide answers the essential questions: "What is a spa pool?" and "How do I choose the right one?" while providing everything you need to know before making your purchase.
New Zealand’s outdoor living market has experienced tremendous growth, with spa pools becoming a staple in Kiwi backyards due to their year-round usability, health benefits, and social value. This article covers all aspects of spa pools, from understanding the technology to choosing between popular models like the Matterhorn 6-Seater Spa Pool.
Understanding Spa Pool Technology
What is a Spa Pool?
A spa pool is a self-contained vessel of heated water equipped with hydrotherapy jets, designed to enhance overall health, wellbeing, stress relief, and promote restorative sleep. Unlike a swimming pool, which is designed for swimming and exercise, a spa pool is designed for seated immersion, massage, and relaxation.
These innovative wellness systems have gained significant popularity in New Zealand as a way to combat the stresses of modern life. Whether used for socialising with friends or solitary decompression, a spa pool provides a controlled environment of warmth and buoyancy.
Key Features of Modern Spa Pools:
Acrylic Shell: Durable, non-porous surfaces that are easy to clean and retain heat.
Hydrotherapy Jets: Strategically placed nozzles that mix air and water to provide targeted massage.
Heater & Pump System: Keeps water at a consistent temperature (usually 36°C–38°C) and circulates water for filtration.
Filtration System: Utilises pleated filters, Ozone, or UV sanitisation to keep water crystal clear.
Insulation: High-density foam to lock in heat and reduce electricity usage.
Hydrotherapy vs Soaking: Key Differences
While a standard bath allows for soaking, it lacks the therapeutic consistency of a spa pool. A bath cools down rapidly, whereas a spa pool maintains a constant temperature, allowing for longer sessions that raise the body's core temperature. Furthermore, the combination of buoyancy (reducing body weight by approx. 90%) and massage (from high-pressure jets) creates a therapeutic effect that passive soaking cannot achieve.
How Spa Pools Work
The Science of Hydrotherapy
Spa pools operate on three pillars of hydrotherapy: Heat, Buoyancy, and Massage.
Heat: Dilates blood vessels, increasing blood flow to damaged tissues and allowing enzymes and endorphins to work more effectively.
Buoyancy: Relieves pressure on joints and spine, allowing muscles to relax completely.
Massage: Directed streams of water relax tight muscles and stimulate the release of natural painkillers.
Heaters, Pumps, and Jets
The "engine room" of a spa pool consists of a circulation pump (for filtration) and jet pumps (for massage). Advanced controllers, such as those found on Alpine Spas Spa Pools, allow users to divert power between seats, customising the pressure from a gentle caress to a deep-tissue massage.
Insulation and Heat Retention
In New Zealand's variable climate, insulation is critical. Modern spa pools utilise multi-layer insulation around the cabinet and shell to trap heat from the pumps and heater. This "thermal flask" effect ensures the water stays hot even when the ambient temperature drops below 0°C (32°F).
Types of Spa Pools
Selecting the right category is the first step in your journey. Alpine Spas Spa Pools offers a diverse range to suit every lifestyle.
Compact Spa Pools
Ideal for couples, empty nesters, or properties with limited space. These 2-3 seater models offer full hydrotherapy performance in a smaller footprint (often under 2.0 metres x 2.0 metres).

Family Spa Pools
The most popular category in New Zealand, typically seating 5-6 people. These models, such as the best-selling Matterhorn, feature a mix of loungers (recumbent seats) and upright therapy seats to accommodate adults and children comfortably.

Large Spa Pools
For the ultimate in personalised therapy, Bullfrog Spas feature the patented JetPak Therapy System™. This technology allows you to swap out the jet backs in each seat, choosing the specific massage type that suits your needs. They are also engineered with ultra-efficient plumbing for maximum power and minimal energy loss.

Proven Health Benefits of Spa Pools
Stress Relief and Mental Health
Immersion in warm water stimulates the release of dopamine and serotonin while reducing cortisol (stress hormone) levels. The gentle noise of moving water and the disconnection from digital devices creates a meditative state beneficial for mental clarity.
Enhanced Sleep Quality
Raising your body temperature in a spa pool 90 minutes before bed creates a subsequent drop in body temperature once you exit. This temperature fluctuation signals to the brain that it is time to sleep, helping you fall asleep faster and achieve deeper REM sleep.
Muscle Recovery and Pain Relief
Athletes and active Kiwis use spa pools to flush lactic acid from muscles after workouts. The increased circulation delivers oxygen-rich blood to tired muscles, accelerating recovery times.
Arthritis and Joint Mobility
The Warm Water Arthritis Foundation notes that warm water therapy can improve flexibility and reduce joint pain. The buoyancy of the water supports the joints, making movement easier and less painful for those suffering from arthritis.
Cardiovascular Health Benefits
Immersing the body in water up to the neck can increase cardiac volume. The pressure of the water works to circulate blood back to the heart, giving the heart a "workout" while the body remains at rest.
Energy Efficiency and Running Costs
Spa Pool Costs in New Zealand
A common concern for new buyers is the ongoing cost. Modern technology has drastically reduced this expense.
Entry-Level: Typically start from $4,995 (like our best-selling Duo Spa Pool) - $8,000 NZD.
Mid-Range: High-quality family spas range from $5,995 (like our best-selling Belmont Spa Pool - $14,000 NZD.
Premium: Luxury models and Bullfrog Spas start from $24,995+ NZD (like our best-selling A5L Select).
The Importance of Insulation
Cheap imports often lack sufficient insulation, leading to rapid heat loss and high power bills. Premium models, like those from Alpine Spas, use multi-layer insulation (often including high-density foam on the shell and cabinet insulation) to minimise running costs.
Operating Costs Explained
For a well-insulated spa pool kept at 38°C (100°F) and used 3-4 times a week, the average running cost in New Zealand is approximately $1.00 - $1.50 per day. This is roughly the cost of a daily cup of coffee to enjoy a private wellness retreat 365 days a year.
Maintenance and Water Care
Owning a spa pool does require some maintenance, but modern systems make it manageable (typically 5-10 minutes a week).
The Weekly Routine
Test the Water: Use a test strip to check pH (acidity) and alkalinity levels.
Balance: Add a small amount of pH buffer (iluka elevate) or sanitiser if the test strip indicates it's needed.
Sanitise: Add a dose of chlorine or your chosen sanitiser after use to kill bacteria.
Rinse Filters: Remove the filters and give them a quick rinse with a hose to remove debris.
Chlorine vs Chlorine-Free vs. Salt Water
Chlorine: The most common and effective sanitiser. Modern "Ozone" and "UV" systems in Alpine Spas reduce the amount of chlorine needed significantly, so you don't get a strong "bleach" smell.
Chlorine-Free: Options like hydrogen peroxide (active oxygen) exist for those sensitive to chlorine. They are odorless but can be more expensive and require careful management.
Salt Water: A common misconception is that salt water spas are chemical-free. They actually use a salt cell to convert salt into chlorine. While the water feels softer, salt is corrosive and can damage heater elements and seals if not managed perfectly. Many experts in NZ recommend standard Ozone/UV systems over salt for longevity.
Filter Care and Longevity
Your filters trap oils and dirt. Every month, they should be soaked in a degreaser solution. Every 3-4 months (depending on usage), you should drain and refill your spa pool with fresh water to prevent "TDS" (Total Dissolved Solids) buildup, which makes the water cloudy and hard to manage.
Installation Considerations
Foundation Requirements
Filled spa pools are heavy (often 1,500kg+). They require a flat, level, and solid foundation. A reinforced concrete pad (100mm thick) is ideal. If placing the spa on a deck, you must consult an engineer to ensure the structure can support approx. 500kg per square metre.
Electrical Requirements
Plug & Play: Some compact models run on a standard 10 Amp household socket.
15 Amp: Many standard family spas require a dedicated 15 Amp socket (which has a larger earth pin).
32 Amp (Hardwired): Large or premium spas with multiple high-power pumps usually require a hardwired connection by a registered electrician.
Fencing and Safety Regulations (Clause F9)
In New Zealand, all spa pools must comply with the Building Code Clause F9 (Restricting Access to Residential Pools).
The Good News: Small heated pools (spa pools) are often exempt from requiring a physical fence if they have a lockable safety cover that meets the standard (ASTM F1346-91) and the side walls are at least 760mm high.
Most Alpine Spas covers are designed to be compliant, but you must always check with your local council for specific requirements in your area.
Choosing the Right Spa Pool for Your Needs
Essential Questions to Consider
Usage: Is this for hydrotherapy (pain relief) or socialising?
Users: How many people will realistically use it at once? (Don't buy a 7-seater if it's just for two people 90% of the time).
Space: Have you measured your available space, including room for the cover lifter?
Ergonomics: Do you prefer a lounger (lying down) or upright seating?
Professional Consultation Recommended
Every body type is different. We strongly recommend visiting a showroom to "wet test" or sit in dry models to ensure the seat depths and jet placements align with your body.

Our spas are designed with targeted jet layouts and powerful pumps to give you a true hydrotherapy experience.
What makes an Alpine Spa different?
Great question – we’re family owned, we don’t cut corners, and we’re known for awesome after-sales support. Plus, our spas are packed with premium components, designed for Aussie backyards.
How much power does a spa use?
Power use depends on the model and how often you use it – but all our spas are built to be energy efficient. With proper insulation and smart heating cycles, running costs on an Alpine Spa are surprisingly affordable.
How hard is it to install a spa?
It’s actually easier than you might think. Most of our spas are plug-and-play or just need an electrician to connect power. We’ll guide you through the whole process – from site prep to delivery to your first soak.
How do I keep the water clean?
Don’t worry – it’s not hard. Our spas have high-quality filtration systems, and we’ll show you exactly how to use simple water care products to keep things crystal clear.
What features should I look for in a quality spa?
Look for great insulation, strong jets, a durable shell, a reliable control system – and solid warranties to back it all up. At Alpine Spas, we use premium components like SpaNet® control systems and USA-made acrylic, and every spa comes with a comprehensive warranty. Best of all, it’s all backed by our friendly, local after-sales team – so you’re supported long after your spa’s delivered.
Should I go for a spa pool with loungers or not?
It really comes down to how you like to relax. Loungers let you fully stretch out and are great for solo soaking. Bench seating gives you more space for friends and family. The good news? Alpine Spas has layouts to suit every preference – and all our seating is ergonomically designed and tested to feel just right.
What’s the warranty and what does it actually cover?
All our spas come with world-class warranties – including coverage on the shell, structure, and all the components. We stand by our products, and we’re here if anything goes wrong. Just get in touch – we make it easy.

Can I finance a spa pool?
Yep – we offer a range of finance options to suit different budgets, including interest-free plans. It’s easy to apply and we can walk you through it.
Do I need a concrete pad or special foundation?
Not always! A concrete pad is ideal, but many customers use pavers, a reinforced deck, or even a spa pad base. We’ll help you figure out what’s best for your site.
How much maintenance is involved?
Not much, really. You’ll need to test the water, clean the filters, and keep things balanced – but it’s easy once you get the hang of it. We’ll show you exactly what to do.
How does delivery work – will you help get it into place?
Yes! We offer full delivery options and can help move your spa into place – whether it’s across the lawn or over a fence. Every delivery is different, and we’ll talk you through what’s needed.”
What’s the difference between a cheap spa and a premium one?
Premium spas use better insulation, stronger shells, and quality parts that last – like Balboa™ control systems and USA-made acrylic. They’re quieter, more efficient, and give a better massage. Cheap spas often cut corners – and you’ll notice the difference.
Can I see the spa in person before I buy?
Yes – and that’s something that sets Alpine Spas apart. We have showrooms across Australia where you can see the spas up close, try out the seating, and get a real feel for the quality. It’s a great way to be confident in your choice before you buy – something not all retailers offer.
