Plunge pools: A complete guide

In the ever-evolving world of backyard leisure, the concept of plunge pools has become a standout trend in Australia, combining practicality, aesthetic appeal, and wellness benefits. Born out of the desire for a pool experience that aligns with the unique Australian lifestyle and caters to space limitations, plunge pools have quickly risen from being a novelty to a staple in contemporary homes across the country.


As Australians increasingly seek a balance between relaxation and recreation without compromising on space, the compact yet luxurious plunge pool provides an ideal solution. Not only do these pools serve as a personal retreat for cooling off during the warm months or heating up in the cooler ones, they also beautifully enhance the landscape of any home. Offering all the allure of a full-sized pool, but in a more manageable form, it's easy to understand why plunge pools are gaining popularity. Whether for an invigorating dip or for the simple pleasure of water-based relaxation, plunge pools are redefining what it means to enjoy the water right in your backyard.

Brought to you by Sapphire Spas, this guide aims to delve deeper into the plunge pool phenomena and reveal why it's the perfect choice for the Australian lifestyle.


What are plunge pools?

At its core, a plunge pool is a small, deep pool designed for the purpose of wading, lounging, or dipping instead of swimming laps. While they lack the size of traditional swimming pools, they make up for it in depth and functionality, providing a refreshing and revitalising experience that's perfect for relaxation, rejuvenation, and even exercise.

Plunge pools typically range from 2 to 7 metres in length and from 2 to 3 metres in width, making them the ideal choice for homes with limited outdoor space. Despite their compact size, plunge pools often have a depth similar to that of a full-size pool, usually between 1.2 to 1.6 metres. This depth, coupled with their often-chilled or heated water, makes them perfect for immersion therapy, a practice that involves switching between hot and cold temperatures to stimulate blood circulation and promote physical healing and relaxation.

Furthermore, plunge pools offer a unique combination of luxury and practicality. They can be stylishly designed to complement your home's architecture, using high-quality materials and featuring options like built-in seating or hydrotherapy jets for a spa-like experience. Equally, they can be equipped with swim jets, turning the pool into a 'swim against the tide' exercise zone - a compact fitness hub right in your backyard.


Benefits of plunge pools

When it comes to making the most of your backyard space, plunge pools bring an array of benefits that are hard to ignore. For one, their compact size makes them an ideal choice for homeowners with limited outdoor spaces. Whether you have a modest backyard or a petite patio, a backyard plunge pool can be tailored to fit snugly, providing a cool oasis or a warm retreat without overwhelming your exterior living space.

But a plunge pool from Sapphire Spas isn't just about fitting into a small area; it's about maximizing the potential of that space. Their versatility allows you to create a serene relaxation spot, a revitalizing hydrotherapy hub, or a dynamic exercise zone. You can take a refreshing dip on a hot day, soothe your muscles after a vigorous workout, or keep up with your fitness regimen using swim jets, all within the convenience of your home.

One of the main health benefits of a plunge pool is improved circulation. The practice of immersion therapy, involving alternating between hot and cold water, stimulates blood flow, helps detoxify the body, and promotes faster muscle recovery. It's a practice well-loved by athletes and fitness enthusiasts, and with a plunge pool, you can enjoy this beneficial therapy right at home.

In addition, plunge pools are much easier to maintain than their full-size counterparts. Their smaller volume of water means fewer chemicals are needed, which can reduce your pool maintenance costs. They also require less energy to heat or cool, making them an energy-efficient choice. Moreover, cleaning is much easier due to the pool's size, saving you both time and effort.

Choosing the right plunge pool

Investing in a plunge pool is a significant decision that involves careful planning and consideration. Sapphire Spas is dedicated to assisting you in navigating this process, ensuring you choose a pool that perfectly fits your requirements, budget, and aesthetic preferences.

Firstly, size is a primary consideration. Although plunge pools are typically compact, they come in a range of sizes. Consider the size of your available space and how much of it you want to dedicate to your pool. The perfect plunge pool should harmoniously integrate with your existing outdoor layout without causing congestion or compromising functionality.

Plunge pool sizes

The design of your plunge pool is another crucial factor. This not only includes the pool's shape but also its colour, tiling, and whether you want additional features like jets, a heating system, or integrated lighting. At Sapphire Spas, we offer a variety of design options, allowing you to select a style that aligns with your vision and enhances your home's aesthetic appeal.

Material selection can significantly impact the lifespan, aesthetics, and maintenance requirements of your plunge pool. Concrete, fiberglass, and acrylic are popular choices, each with its pros and cons. For example, concrete offers durability and flexibility in design but requires more maintenance, while fiberglass and acrylic are lower maintenance and quicker to install but offer less design flexibility.

Location is also key. Your pool should be easily accessible but also blend seamlessly with your landscaping. It's also worth considering privacy, sun exposure, and proximity to your home. An expert from Sapphire Spas can help assess your property and recommend an optimal placement.

Lastly, consider cost, not just in terms of initial outlay but also ongoing maintenance and running expenses. Our team at Sapphire Spas is transparent about costs and can help you understand the full investment involved, making sure there are no unexpected surprises.

Plunge pool installation

First, the site for the pool must be carefully assessed and prepared. This involves checking for underground utilities, grading the ground, and creating a solid base for your plunge pool. Depending on your chosen location and the characteristics of your property, this process might involve excavation, levelling, or the construction of retaining walls. Installing your spa.

Next comes the placement and installation of the plunge pool itself. For plunge pools made of fibreglass or acrylic, this involves carefully lowering the pre-fabricated pool shell into the prepared site. Concrete pools, on the other hand, require a construction process that involves forming, pouring, and curing the concrete.

Once the pool shell or structure is in place, it's time for plumbing and electrical work. This includes the installation of filtration and heating systems, as well as any additional features like lights or jets. Given the complexity of these systems and the potential safety risks involved, this step should always be undertaken by licensed professionals.

Finally, there's the finishing stage, which involves final landscaping, pool interior finish application, filling the pool, and balancing the water. This stage also includes the installation of any additional amenities like poolside decking, lighting, or landscaping features.

Each step of this process requires specific technical knowledge and skills, underlining the importance of professional assistance. At Sapphire Spas, our team of trained professionals will ensure that each stage of the installation process is performed meticulously, adhering to the highest standards of quality and safety.

Plunge pools vs regular swimming pools

When considering a new plunge pool for your backyard, you may be wondering about the differences between a plunge pool and a regular swimming pool. Here are some key points to help you understand the distinctions and make an informed decision:

  1. Size and space : Plunge pools are typically smaller than regular swimming pools. They are designed for relaxation, cooling off, and enjoying hydrotherapy benefits. On the other hand, regular swimming pools are larger and meant for swimming, exercising, and recreational activities. A plunge pool may be the ideal choice if you have limited space or prefer a more intimate pool experience.
  2. Depth and purpose : Plunge pools are generally shallower, with a depth that allows for wading, lounging, and soaking. They are perfect for creating a tranquil and refreshing oasis in your backyard. On the other hand, regular swimming pools are deeper and designed for swimming laps and engaging in water sports. The depth and purpose of the pool will depend on your preferences and intended usage.
  3. Features and accessories : Both plunge pools and regular swimming pools can be customised with various features and accessories to enhance your pool experience. Plunge pools often incorporate spa features, such as hydrotherapy jets and seating areas, for added relaxation and therapeutic benefits. Regular swimming pools may include diving boards, water slides, and other recreational elements for family fun and entertainment.
  4. Maintenance and cost : Plunge pools generally require less maintenance and incur lower costs than regular swimming pools. With their smaller size and reduced water volume, plunge pools are easier to clean, maintain water chemistry, and manage overall upkeep. Additionally, the initial installation cost of a plunge pool is typically more affordable than that of a regular swimming pool.



Choosing between a plunge pool and a regular swimming pool depends on your specific needs, preferences, and available space. When deciding, consider the pool's primary purpose, the desired maintenance level, and your budget. Sapphire Spas offers a range of plunge pools to suit your individual requirements, ensuring you find the perfect fit for your backyard oasis.



Sapphire plunge pools are the ideal alternative to the typical backyard swimming pool BUT you can jump in all year round. With our economical heating systems and the smaller body of water, it’s realistic to keep your plunge pool warm all winter and then cool it down for the summer months with an energy efficient external heat and cool pump.


Plunge pool activities

Backyard exercise:

It’s a great idea to position your plunge pool close to the house so you can step out the back door and use it as your home gym. We like to add a couple of swim jets at the pool end of our plunge pools for you to have a light exercise or for the kids to play in the jet stream.

Even with just one pump/swim jet running, you can exercise at a walking or jogging pace, much like wading through the water in the ocean. This is great for your cardio fitness and helps build abdominal strength through resistance.


Swimming lessons:

Instead of an afternoon at the hot and stuffy local pool, come straight home after school and hop in your plunge pool with the kids to teach them to kick supported whilst holding the grab rail or freestyle arms against just one swim jet to hold them in place. Throw in some pool toys to encourage underwater play, and finish off with free splashing and a fruit platter. Dry off on your deck, then start the bbq when Dad gets home.

A day at the beach:

‘I love going to the beach, but Mum & Dad only took us a few times last summer because it was too cold! Now my baby sister can play on the steps with Mum while Dad & I play water games in the deep end.’

The wide steps & open plan layout of myWatersedgeSERIES are ideal for child’s play & toddler splashing. The Sapphire plunge specification with two powerful swim jets is just enough water movement for kids to swim against and create a whirlpool for pool toy fun. There’s even enough room in the myWatersedge6.0m for kids to safely jump in from the edge.


Rehabilitation & mobility:

‘Being able to exercise freely without my joints aching is something I never thought I would be able to experience again. My swim spa has given me a new lease on life.’
The power of the two swim jets in plunge pools can be adjusted to allow for any level of competency and even turned off for stretch or rehabilitation exercises.

These effective rehabilitation tools can help maintain mobility in older years as you exercise, supported by the buoyancy of the warm water.


Water pilates & yoga

As long as you design your routine so your head is above the water, these small pools can also be used for water pilates, stretching or yoga. You could introduce a resistance band for support or use the seated areas throughout the pool. Try some water weights or use the swim jets for pressure to move around the water.



myWatersedgeSERIES of plunge pools is available in 4.0m, 5.0m & 6.0m. This has a simple yet sophisticated rectangular design with wide entry steps, with seating at one end and swim jets in a large pool area at the other. This is the most popular in our plunge pool range in Australia.



myWorkoutSERIES of plunge pools are manufactured at 4.5m, 5.0m & 6.0m in length. This model is more similar to our higher priced plunge pool with swim jets which are more built for massage. myWorkout has a single lounger and 3 moulded massage seats at the spa end and still the large pool area at the swim jet end. myWorkout plunge pools have an ideal number of massage jets to allow you to get the most out of the pumps that are availble in this specification of pool.
