Concrete vs Fibreglass Pools: Which Pool Is Best for Your Backyard in Australia?
When planning a new swimming pool, one of the biggest decisions homeowners face is concrete vs fiberglass. Both options have their advantages, but the right choice depends on your block, your vision, and how you want to use the pool.
At Cloud 9 Pools, we specialise in custom concrete pools, often on challenging sites where flexibility and precision matter most. Here’s a clear breakdown of how the two pool types compare.
1. Design Flexibility
Concrete Pools
Concrete pools are completely custom-built. This means the pool can be designed to suit any shape, size, or depth, making them ideal for unique backyards or architectural homes.
You can incorporate features such as:
- Integrated spas
- Beach entries
- Custom bench seating
- Infinity edges
- Water features
- Portholes or viewing windows
Fibreglass Pools
Fibreglass pools are pre-manufactured shells. They come in set shapes and sizes, which limits how much the design can be tailored to your space.
If your backyard suits one of the available moulds, fibreglass can be a good fit. But if you want something truly unique, options are limited.
Winner: Concrete (for design freedom)
2. Installation Process
Fibreglass Pools
Fibreglass pools are manufactured in a factory and delivered as a single shell. Because of this, installation is generally quicker.
However, access to the site is crucial. The shell must be transported by truck and lifted into place by crane.
Concrete Pools
Concrete pools are built on-site, allowing them to be constructed even in difficult locations — including tight access blocks, sloping sites, or areas with obstacles.
While construction takes longer, it allows for far greater precision and customization.
Winner: Fibreglass (for speed), Concrete (for accessibility and flexibility)
3. Durability and Strength
Concrete Pools
Concrete is known for its structural strength and longevity. With proper construction and maintenance, concrete pools can last for decades.
They also handle ground movement and complex engineering requirements better than prefabricated shells.
Fibreglass Pools
Fibreglass pools are durable but rely on the integrity of the shell. Over time, surfaces can fade or require resurfacing.
Because they are a single moulded piece, repairs can sometimes be more complicated if structural issues arise.
Winner: Concrete
4. Surface Finish
Concrete Pools
Concrete pools can be finished with a range of interior surfaces, including:
- Glass bead finishes from Designer Beadcrete
- Fully tiled pools
These finishes provide beautiful textures and colours that can dramatically enhance the look of the pool.
Fibreglass Pools
Fibreglass pools come with a gelcoat surface, typically in a limited range of colours.
While smooth and comfortable, they don’t offer the same level of customisation as concrete finishes.
Winner: Concrete
5. Cost Considerations
Fibreglass Pools
Fibreglass pools are often marketed as the more affordable option, largely because the shell is mass-produced and installation can be quicker.
However, Many fiberglass pool prices you see advertised are base packages. Once you begin adding the same inclusions commonly found in concrete pools- such as custom lighting, heating, premium filtration systems, water features, coping and spas- the price can increase significantly. Lets also not forget the crane cost.
By the time these upgrades are included, the overall cost of a fiberglass pool can become like for like with a concrete pool.
Concrete Pools
Concrete pools generally have higher upfront price of paper, because they are individually engineered and built to suit each property.
However, they already include the customisation and flexibility that many homeowners end up adding to fiberglass pools later. When comparing two pools with similar features and finishes, the final costs are often closer than many people expect.
Winner: Often closer than it first appears.
6. Best Choice for Difficult Sites
Many properties across the Illawarra and south coast region have:
- Sloping blocks
- Tight access
- Sewer or drainage infrastructure
- Complex landscaping requirements
Concrete pools are often the best solution for challenging sites because they can be engineered and built around these constraints.
Which Pool Is Right for You?
If you want a fast installation and a standard shape, a fibreglass pool may suit your needs.
But if you want a luxury pool designed specifically for your backyard, lifestyle, and home, a custom concrete pool offers unmatched flexibility, durability, and visual impact.
