POOL RENOVATIONSWhen planning a new swimming pool, one of the most common questions NSW homeowners ask is: “What pool shape is the cheapest to build?” Pool shape choices can suit a variety of Aussie backyards, offering both versatility and affordability for different outdoor spaces.
While materials and site conditions play a big role, pool shape alone can significantly impact the overall cost. Some shapes require less labour, simpler engineering, and fewer materials — making them far more budget-friendly. Rectangular pools are often considered the most affordable option for many Aussie backyards due to their simple design.
Let’s break down which pool shapes are the cheapest in NSW, and why. There are many shapes available, but not all are equally cost-effective—rectangular pools are usually the most affordable option.
The Cheapest Pool Shape in NSW: Rectangular Pools
In most cases, rectangular pools are the cheapest pool shape to build in NSW.
Why Rectangular Pools Cost Less:
- Simple excavation
- Straight formwork (less labour)
- Easier engineering and reinforcement
- Standard tiling and coping
- Faster construction time
Because they’re straightforward to design and build, rectangular pools reduce labour hours and construction complexity — which directly lowers costs.
💡 Rectangular pools are also highly popular in Sydney due to their clean, modern look and excellent resale appeal.
Other Affordable Pool Shapes (Compared)
1. Square Pools
- Similar cost to rectangular pools
- Compact footprint = lower excavation costs
- Ideal for small or urban backyards
Square pools are a close second when it comes to affordability, especially for plunge-style designs.
2. Plunge Pools
- Often rectangular or square
- Smaller volume = lower material costs
- Perfect for tight blocks
While not technically a “shape”, plunge pools are usually built in simple geometric forms, making them one of the most cost-effective inground pool options in NSW.
Pool Shapes That Cost More
Some pool shapes cost significantly more due to increased labour and engineering:
❌ Freeform Pools
- Curved edges require custom formwork
- More complex excavation
- Longer build time
- Higher tiling and finishing costs
❌ Kidney-Shaped Pools
- Irregular curves increase labour
- Harder to integrate with paving and fencing
❌ Custom or Architectural Shapes
- Fully bespoke designs
- Advanced engineering
- Premium finishes and features
These shapes can look stunning, but they come with a higher price tag.
Does Pool Shape Matter More Than Pool Type?
Pool shape affects cost — but pool type matters just as much:
- Fibreglass pools are usually cheaper overall, but shapes are limited. They are known for easy installation, as most kits come with all necessary components and instructions, and are often used for in ground pools.
- Concrete pools cost more upfront but offer unlimited shape options. Pre cast concrete is also available as an alternative for certain installations, providing durability and flexibility for semi-inground or above-ground pools.
- Vinyl-lined pools are cheaper initially but have higher long-term costs
When combining shape + material, the cheapest inground pool option is typically a rectangular fibreglass pool or a small rectangular concrete plunge pool.
When installing a pool, the pool shell is a major factor in both durability and upfront cost. The process of installing an in ground pool can vary in complexity depending on the material chosen, with fibreglass generally being more straightforward than concrete.
Pool Area and Surrounds: How Layout Impacts Cost
When designing your swimming pool, the layout of the pool area and its surrounds can make a big difference to both your budget and the final look of your backyard. A thoughtfully planned pool area not only enhances your property’s value but also transforms your outdoor space into a resort-style retreat.
For inground pools, integrating the pool seamlessly with your landscape can create a dream pool that feels like a natural extension of your home. Features such as retaining walls can help manage sloped sites, while water features and LED lighting add a touch of luxury and ambiance, perfect for evening swims or entertaining guests. If you’re considering a fibreglass pool or a concrete pool, the pool type will influence how easily you can customise the layout and add features.
Above ground pools offer a different approach, often paired with stylish decking to provide safe and easy access. This can be a cost-effective way to achieve a resort style living feel without the higher price tag of extensive excavation. The choice between ground pools and above ground options will depend on your backyard’s ground conditions, your desired lifestyle, and your budget.
By carefully planning your pool area—whether you opt for a simple, functional design or a more elaborate resort style setup—you can create a pool that suits your lifestyle, complements your property, and delivers lasting value.
How to Keep Pool Costs Down (Without Sacrificing Quality)
If budget is a priority, here’s how to reduce costs smartly: Making smart choices can help you save money without sacrificing quality.
✔ Choose a rectangular or square shape
✔ Keep the size modest
✔ Limit custom curves and angles
✔ Use standard coping and finishes
✔ Design the pool to suit your site (not against it)
✔ Tailor the design to customers’ needs for satisfaction and cost-effectiveness
At the same time, it’s important not to compromise on build quality or compliance.
By focusing on the right options, you can create your own pool that fits your budget and lifestyle.
Pool Permits and Safety Compliance in NSW
Before you start your pool installation in New South Wales, it’s crucial to understand the safety standards and permit requirements that apply to every swimming pool project. NSW has strict regulations in place to ensure that all pools are safe for families and meet the highest safety standards.
Working with a licensed pool builder is the best way to navigate the permit process and ensure your new pool is fully compliant. From the initial application to final inspection, your builder will help you meet all legal requirements, including proper fencing, self-closing and self-latching gates, and the use of approved cleaning equipment. These measures are designed to protect your family and visitors, making your pool area a safe and enjoyable space.
Additionally, regulations cover ongoing responsibilities such as water top ups and regular maintenance, so it’s important to factor these into your planning. By staying informed and working with experienced professionals, you can enjoy peace of mind knowing your pool installation meets all New South Wales safety standards and is ready for years of family fun.
Best Value Option for NSW Homes
While rectangular pools are the cheapest shape to build, many NSW homeowners choose rectangular concrete pools because they offer:
- Long-term durability (30–50+ years)
- Timeless, modern design
- Strong resale appeal
- Better integration with landscaping
- Excellent value over time
- A great option as a family pool, providing enjoyment and safety for all ages
A well-designed rectangular concrete pool delivers the best balance between upfront cost and long-term value.

Real-Life Examples: NSW Pool Projects on a Budget
Across New South Wales, many Australian families have turned their backyard dreams into reality with cost-effective swimming pool projects. Take, for example, a Sydney family who chose a fibreglass pool paired with a sleek deck, creating a perfect pool area for both relaxation and entertaining. By selecting a variable speed pump and an energy-efficient heating system, they kept ongoing costs low while enjoying a comfortable swim even on cooler days.
In Newcastle, another homeowner opted for a compact plunge pool with a minimalistic surrounding area—ideal for cooling off on hot summer days without the expense of a larger installation. Their choice of a low maintenance, robotic cleaning system made pool care simple and affordable, freeing up more time to enjoy their new outdoor space.
These real-life stories show that, with careful planning and the right pool type—whether it’s an above ground pool, a fibreglass pool, or a smaller inground option—it’s possible to create a high-quality, low maintenance pool area that fits both your lifestyle and your budget. By focusing on essential features and smart equipment, NSW families are proving that the perfect pool doesn’t have to come with a hefty price tag.
