Key Considerations When Choosing a DIY Plunge Pool Kit

Growing up, I remember the magic of having a pool in our backyard—a place where we could escape the heat, relax, and spend endless hours splashing around with family and friends. Now, I see so many people dreaming of creating that same kind of retreat in their own backyards. But let’s be open here: not everyone has the space—or the budget—for a full-sized pool.

That’s where a DIY plunge pool kit comes in. It’s the perfect way to enjoy the perks of a backyard pool without the massive footprint or price tag. If you’re ready to ditch trying to stay cool under a fan, I’ll walk you through a few pointers to help make the right choice for your space, budget, and lifestyle. 

1. Assessing Your Backyard Space and Pool Size Needs

The first thing to look at is your backyard space. It’s crucial to measure and visualise exactly where you want your plunge pool to go.

Here are a few ways to do it:

• Use Google Maps: Get a bird’s-eye view of your backyard with Google Maps. This can help you understand your space better and plan around existing features.

• Mark Out with Stakes and String: Walk around the area and mark out the pool’s footprint with stakes and builder’s string (cheap as chips from your local hardware store). This is a simple way to visualise the pool’s size and position in your yard. Ideally, you want at least 1.5m between the pool and any walls or pool fencing. If space is tight, you can get away with only one side at 1.5m.

• Try Our Virtual Reality (VR) Tool: For a more immersive experience, use our VR tool to see the pool in your actual space. This cracking tool allows you to test different sizes, colours and designs, making it easier to find the perfect fit for your backyard.

• Have Your Site Plan Checked: Once you have had your site plan drawn up, run it past your local council or a private certifier for any glaring issues that will get in the way of your permit being issued. You can do this before formally submitting your permit application. It will save you time, money and from unexpectedly from having to change the shape or size of your pool.

Quick Tip: Using a combo of these methods will give you the best results. The VR tool, in particular, is a beauty for seeing how different plunge pool models will look in real-time within your own space.

2. Selecting the Right Pool Type: Fibreglass vs. Concrete vs. Vinyl Liner

Choosing what your plunge pool is made from is a big decision. Fibreglass, concrete, and vinyl liner pools each have pros and cons, so it’s all about finding what suits your budget, maintenance preference, and backyard style. 

Fibreglass Pools: The Low-Maintenance Champion

Fibreglass pools are pre-formed, durable, and easy to maintain. Their smooth gelcoat surface resists algae and needs fewer chemicals. Installation takes under a week, and their insulating properties keep the water warmer.

While designs are limited to pre-made moulds, fibreglass strikes a great balance between cost and longevity, with warranties up to 35 years. It’s a great option for anyone wanting less fuss and long-term value. 

Concrete Pools: The Customisation King

Concrete pools are perfect if you’ve got big ideas. From infinity edges to unique shapes, the design possibilities are endless. But with that freedom comes higher costs, more maintenance, and longer installation times—usually between two and three months or longer with wet weather.

Concrete’s porous surface demands regular cleaning and acid washes. While these pools can last decades, they require the most ongoing care. 

Vinyl Liner Pools: The Budget-Friendly Option

Vinyl liner pools are affordable upfront and gentle on the skin. They’re quick to install but need liner replacements every 5-10 years, which adds up. They’re less durable, so damage from sharp objects or UV can be a headache.

For a cheap initial outlay, vinyl liners are great—but be ready for higher costs down the track.

Consideration: For most people choosing a DIY plunge pool, fibreglass offers the best balance of durability, low maintenance, quick installation and cost saving. If time and a bigger budget is on your side and you’re looking for creative freedom, concrete pools are the way to go.

3. Design and Shape Options for Your Plunge Pool

One of the most enjoyable parts of choosing a plunge pool kit is picking the shape that suits your backyard and how you plan to use it. Don’t worry about keeping up with the Joneses. Make no mistake - you feel just as cool and relaxed in a plunge pool as you do in a 10m x 4m pool.

Here’s what to consider:

• Popular Plunge Pool Shapes: Rectangular pools maximise swim space and give your yard a clean, modern look, while round pools add a softer, more organic feel. Both are great choices and can fit into backyards of all sizes—whether you’ve got heaps of space or a small patch.
• Customisation Options: Many plunge pool kits come with built-in seating, ledges, or steps. Think about how you’ll use the pool. If you want to kick back and relax, look for a design with seating. If you’re after a minimalist look, a simple, sleek shape is the way to go.

   

Quick Tip: Choosing the right shape, features and landscaping can make a small pool feel larger and add a touch of luxury, even if you’re working with a compact space.

4. Budgeting for Your DIY Plunge Pool Project

Setting a budget is like diving into cold water—it’s a bit of a shock at first, but you’ll thank yourself later. When it comes to a plunge pool, the kit price is just the start. There are extras lurking around every corner, so it’s important to plan carefully to avoid any nasty surprises.

• Kit Cost vs. Additional Expenses: A DIY pool kit is a cracking way to save money, but don’t let the upfront price fool you. You’ll need to account for fencing, excavation, electrical work concreting, and council approvals to name a few. .
• Get Itemised Quotes to Avoid Budget Blowouts: When it comes to your pool kit and upgrade options, make sure you know exactly what you’re paying for. Ask for an itemised list of what’s included in the kit and the cost of any add-ons, from heaters to lighting. Insist on details upfront—it’s the easiest way to keep your budget in check and your stress levels down.
• Setting a Realistic Budget: To help you break down the costs, we recommend checking out our comprehensive guide. It covers everything from pool sizes to filter costs and is full of budgeting tips that make the whole process easier. Once you have worked out your budget, add 10% as a “just in case” fund.
• Cost-Saving Tips: A smaller, rectangular design can save you big bucks, and DIY landscaping can make a real difference. And if you’ve got a mate with an excavator, it’s time to call in that favour—they’re worth their weight in gold.
  

5. Understanding Installation Requirements and Timeline

Installing a DIY plunge pool isn’t as hard as you might think, but it’s not exactly a walk in the park either. Knowing what to expect can save you time, money, and a fair bit of frustration.

• DIY Installation vs. Hiring Help: While plunge pool kits are designed with DIY enthusiasts in mind, some tasks legally require a licensed professional. For example, all electrical work must be done by a licensed electrician—no exceptions unless you’re a sparky yourself. When it comes to heavy lifting, like excavation or backfilling, getting a bit of help can speed up the job significantly. I once wheelbarrowed in a silly amount of concrete to save a paltry amount of money, wishing I’d called in some mates or hired a contractor. Lesson learned—work smarter, not harder.
• Timeline to Expect: The timeline depends on your pool size, site prep, and whether you’re flying solo or bringing in professionals. On average, allow a week from the start of digging to having your first swim.

Quick Tip: Preparation is key. Make sure everything—from permits to equipment hire—is sorted ahead of time. That way, you’re not left standing in your backyard thinking, “What’s next?”

6. Considering Pool Accessories and Enhancements

Once you’ve chosen your plunge pool kit, it’s time to think about the extras. Accessories and upgrades can turn your plunge pool into a backyard showstopper while adding comfort and style.

• Heating Option : If you want to extend your swimming season, a heater is a ripper investment. Most pool owners use heating to stretch their pool time—starting six weeks before summer and keeping it going six weeks after. Heat pumps are a great choice for their affordability, reliability and low running costs. Over the past four years, the price of heat pumps have come right down, while the cost of buying solar heating has increased.
• Lighting: Underwater LED lighting isn’t just practical—it gives your pool a touch of magic at night. It’s a simple upgrade that makes evening swims a lot of fun and keeps your pool as the centre of attention once the sun goes down.
• Water Features: For a bit of luxury, consider adding spa jets to your plunge pool. It’s a cost-effective way to create a pool-and-spa combo without the price tag of a standalone spa. Spa jets can add a relaxing massage element, perfect for unwinding after a long day. Make sure the spa jets are the hydro-therapy, roto (spinning/massaging) jets used in standalone spas. Cheap pool kit companies use pool return jets, which are next to useless as spa jets.

Quick Tip: Decide on your accessories before installation. Heating can be added after installation without too much trouble. However, trying to add lights or spa jets after installation is next to impossible….and expensive.

7. Safety and Compliance: Meeting Australian Pool Standards

In Australia, pool safety isn’t just a good idea—it’s the law. Before you start digging, make sure you understand the safety requirements to keep your plunge pool compliant and your friends and family safe.

• Fencing Requirements: Pool fencing is mandatory across Australia. Regulations vary slightly between states and territories, but all fences must meet strict height and gate requirements to prevent unsupervised access. Unfortunately, there are plenty of stories of pool owners who thought they would save a few bucks by leaving compliant fencing for down the track. Council’s use subscription based aerial photography to routinely check for unapproved pool installations or pools without correct fencing. Thinking “they’ll never know” is well and truly in the past
• Council Approvals: All councils require permits before a pool can be installed. You’ll need to submit detailed plans covering everything from fencing to filtration systems. Installing a pool without a permit can lead to a hefty fine, and if the pool can’t be made compliant, you may even be forced to remove it altogether.

Quick Tip: A quick call to the council early in the process can save you time and prevent unexpected expenses down the line. In case you're tempted to roll the dice and take your chances, the cost of fines and remedial work always exceeds any money you might save.
