Cheap Plunge Pool Options: How to Build a Plunge Pool on a Budget (2026)

Last Updated: 13 October 2026

In short: The cheapest plunge pool upfront is an above ground vinyl liner pool, but the liner needs replacing every 6 to 10 years. The cheapest quality option is usually a fibreglass plunge pool kit bought direct, with licensed trades you book yourself. The biggest savings come from planning early, comparing quotes and choosing energy-efficient equipment.

Key takeaways

• A cheap pool doesn't have to mean a low-quality pool. It means doing some project management.
• DIY doesn't mean digging. You buy the kit direct and book licensed trades. You're managing, not labouring.
• Vinyl liner pools are cheapest upfront; fibreglass plunge pools usually cost less over their life (around 30-year lifespan, low maintenance).
• Allow around 4 months from permits to first swim, so start planning well before summer.
• A variable speed pump and a pool cover cost more upfront but cut running costs every year.

1. Plan, plan and plan some more!

Planning your plunge pool is an essential step that can save you both time and money in the long run. Having a plan ensures that you make informed decisions, avoid costly mistakes, and achieve the desired results.

Whether you're opting for a DIY project or hiring professionals, planning for your plunge pool on budget gives you a clear roadmap to follow, enabling a smooth and hassle-free pool installation process.

• The first item to check off is a Council permit. Each Council has different requirements so give them a call to get started. Don't forget the pool fence: it's part of your approval and one of the most common causes of delay.
• Measure your space - what size pool will work well for your backyard? Think about lounging space, you want to have enough room around your pool to relax so allow room for sun lounges and chairs. A plunge pool is a great choice as it won't dominate your garden so there's still space for a grassed area. Our 7 favourite plunge pool kits for small backyards lists real dimensions.
• Think about timing - from permits to completed pool it can take on average 4 months so if you want to be swimming in the summer you need to kick things off well before. If you haven't started approvals yet, aim for late summer.
  
  

2. Get quotes (lots of them!)

If you're opting to project manage the swimming pool build, then getting quotes from multiple trades will give you more of an idea about what to expect. It's only when you talk to different trades that you get a clearer idea about the installation process and can start to compare inclusions. While it might be tempting to rush into the project and go with the first option you find, taking the time to gather multiple quotes is a smart move. A cheap pool installation quote may sound great, but delve into the details of what's been included. When it comes to an installer, each licensed pool installer may have different pricing structures, expertise levels, and services included in their packages. By obtaining quotes from several sources, you can make a well-informed decision based on a comprehensive comparison. This not only helps you find the most competitive price but also ensures that you're working with reliable and experienced professionals who understand your vision and can bring it to life.

If you're project managing the install and coordinating the excavation company, installer and other trade professionals then you can save even more money. This DIY pool approach is more involved and you will need to obtain more quotes but it does increase your cost savings. Not sure who to call? Here's every trade you need, in the order to book them.

Top Tip: Check the builder/installer is licensed and take the time to confirm their details.

3. What is the cheapest type of plunge pool?

Plunge pools can be made in a range of materials but each comes with its advantages and disadvantages.

Vinyl liner pool

At the cheaper end of the spectrum is a liner plunge pool. A vinyl liner pool is also known as a modular pool and is the easiest and quickest plunge pool to install. It is an above ground pool that consists of posts, panels and a liner to create a range of different pool sizes and shapes. This is the most budget friendly plunge pool as there is minimal excavation required. An advantage of this type of pool is that you can take it with you if you move house! However the disadvantages relate to the longevity of the materials and the overall look of the pool. The pool liner will need to be replaced every 6-10 years which needs to be factored in to the ongoing costs of this style of pool. Additionally, a liner pool isn't as aesthetically pleasing as an inground pool and doesn't add value to a property like an inground pool will.

Fibreglass plunge pool kit

With a fibreglass plunge pool kit you get all the benefits of an inground fibreglass pool at a fraction of the cost of a pool from a traditional all in one pool company. A fibreglass plunge pool will last 30 years and the materials used are renowned for their low maintenance properties. Fibreglass is a non porous surface so algae is not an issue like concrete pools so less chemicals are required. A fibreglass pool adds the same value to your home as a concrete pool so is a great option. Prefer to stay out of the ground? An above ground fibreglass pool is another budget-friendly route.

Precast concrete pool

A precast concrete pool is a great option if you want the look and feel of a concrete pool but don't want to wait for the long installation process of a custom built pool. With this option getting crane quotes is a must. As the pool is made from 100% concrete, the crane required to lift them is much more expensive than a fibreglass pool. A concrete pool also has the disadvantage of more chemicals needed to maintain the water chemistry and greater maintenance so this is the more costly of the plunge pool options. We compare the two in detail in fibreglass vs precast concrete plunge pools.

4. Licensed installer vs full DIY: which saves more?

With a DIY plunge pool you have the option of engaging a licensed pool installer who can take care of every stage of the installation. Some installers will take care of the Council permits, excavations right through to the landscaping. This is a great option if you want to go down the DIY route and take advantage of savings but want to have a professional take care of all aspects. With Swimming Pool Kits Direct you can request the details of a local installer in your area who previous customers have used. With this option, you will still save money as you are able to get the pool shell and equipment at a reduced price by buying direct and also take time to get multiple quotes from installers. Having control of who installs your pool allows you to have greater confidence in the expertise of your installer and allows you to have more control over the installation process.

If you would like to take control of the entire project, a full DIY installation will lead to the greatest cost savings. By engaging a separate company to take part of each stage of the installation, you are able to gain multiple quotes and gain the best possible price. This option requires more work and attention to detail as you will need to organise the timeline of the installation and arrange for the correct trades at the right time but it's a popular choice. Remember: you're coordinating licensed trades, not doing the licensed work yourself.

5. How do you keep plunge pool running costs down?

It's not just the initial upfront costs to consider with a budget pool but also the ongoing maintenance. With any plunge pool package, equipment is an important component. Every pool needs a pump, filter and chlorinator and the equipment you choose can have a big impact on your ongoing costs. When it comes to pumps, it can be tempting to go with the cheapest, however this can be costly in the long run. A single speed pump has a cheaper upfront cost compared to a variable speed pump, however the cost of the electricity to run a variable speed pump is significantly lower. A variable speed pump offers multiple programmable speeds, allowing you to select the most efficient speed setting depending on your filtration, cleaning and water feature needs. A single speed pump always operates at maximum speed and so draws more electricity. The variable speed can be set to a lower speed for tasks such as water circulation which in turn leads to greater energy efficiency and lower electricity costs over time. More detail: single speed vs variable speed pool pumps.

A worthwhile investment is a pool cover. Like the variable speed pump this is an initial upfront cost, however over time the savings are significant. A pool cover such as a Daisy cover reduces evaporation which in turn reduces the amount of chemicals required and water to top the pool up. It's also a great idea to have a pool cover to prevent debris entering the pool which reduces the cleaning costs of the pool.

Conclusion

Building a plunge pool on a budget is an exciting and rewarding project that will allow you to take the ultimate staycation! With careful planning and a clear idea on the type of plunge pool that best suits you, you can create a resort in your own backyard without breaking the bank. Whether you decide to tackle the project yourself or opt for an all in one installation package, comparing quotes from various pool installers or trades ensures you get the best value for your money. The key to maintaining your plunge pool on a budget lies in adopting long-term savings strategies. Investing in pool covers and energy-efficient equipment will help you enjoy a sparkling pool without incurring unnecessary expenses in the long run.

With these budget-friendly tips and a bit of dedication, your dream of having a plunge pool can soon become a reality. Start planning and create a little slice of paradise at home, a place where you can relax, create memories and make a splash for years to come!
