When it comes to renovating or upgrading an existing swimming pool in Australia, one popular choice many homeowners consider is applying fibreglass over a concrete pool. This approach – also referred to as converting a concrete pool with a fibreglass coating – can breathe new life into older structures, improve their surface, and simplify ongoing maintenance. Below, we explore everything you need to know about fibreglassing a concrete pool, what it entails, its potential drawbacks, and its cost-effectiveness.

What is a Fibreglass Concrete Pool?
A fibreglass concrete pool is essentially a traditional concrete pool that has been lined or coated with fibreglass. Instead of building a brand-new fibreglass shell, professionals apply multiple layers of fibreglass laminate over the existing concrete surface. The result? A fibreglass lined concrete pool that combines the strength of concrete with the smoothness and lower maintenance requirements typically associated with fibreglass pools.
Why Convert a Concrete Pool to Fibreglass?
- Smooth Surface: Concrete surfaces can become rough and prone to cracking over time. Fibreglass, on the other hand, offers a sleek, smooth finish that is more comfortable underfoot.
- Reduced Algae Growth: The non-porous fibreglass surface makes it difficult for algae to take hold, reducing chemical usage and maintenance effort.
- Aesthetic Upgrade: Renewing a tired-looking concrete pool with fibreglass can instantly modernise its look and feel.
- Cost-Effective Renovation: When done by professionals, fibreglassing a concrete pool can save you from the expense of building an entirely new structure.
Fibreglassed Concrete Pool Surface
The fibreglassed concrete pool surface is created using layers of fibreglass mat, resin, and a topcoat (gel coat). Professionals at Pools 101 typically follow these steps:
- Inspection and Preparation: We thoroughly inspect your concrete pool for cracks or structural damage. Any weak spots are fixed before the fibreglass coating is applied.
- Surface Cleaning and Roughening: The existing concrete surface is cleaned and abraded to ensure the fibreglass material adheres properly.
- Fibreglass Application: Multiple layers of fibreglass resin and reinforcing material are laid down, creating a strong, watertight shell.
- Finishing: A gel coat or specialised topcoat is applied to seal and protect the fibreglass. This coating can be tinted in various shades to suit your personal style.
Fibreglassed Concrete Pool Problems
While there are many advantages to installing fibreglass over concrete pool structures, there are potential challenges to consider:
- Improper Installation: If the pool is not thoroughly cleaned and prepped before the fibreglass is applied, bonding issues could lead to delamination (where the fibreglass layer starts to peel away).
- Underlying Structural Damage: In cases where the original concrete shell is severely compromised, simply fibreglassing a concrete pool may not solve underlying structural issues. A professional assessment is vital to ensure that the pool can safely support a new fibreglass surface.
- Longer Repair Times: Should the fibreglass layer sustain damage, repairs might require draining the pool, which could be disruptive during the warmer months.
How Much Does It Cost to Fibreglass a Concrete Pool?
The cost of fibreglassing a concrete pool in Australia can vary widely depending on factors such as:
- Size and Shape of the Pool: Larger or irregularly shaped pools require more materials and labour.
- Condition of the Existing Pool: Surface cracks, leaks, or structural damage will need repairing before the fibreglass coating can be applied.
- Customisation: Opting for premium gel coats or additional design features (like mosaic tiling around the edges) can increase overall costs.
On average, a standard-size pool conversion might range anywhere between AUD $8,000 to $15,000 or more. For an accurate quote, it’s best to contact professionals like Pools 101 for an on-site inspection and customised pricing.
How Long Will the Fibreglass Surface Last?
A concrete pool with fibreglass coating typically enjoys a lifespan of 15 to 20 years before needing significant repairs or re-coating. Proper maintenance, including balancing pool chemicals and promptly addressing any repairs, can extend that lifespan even further. Fibreglass surfaces are known for their durability and can handle Australia’s harsh climate and fluctuating temperatures very well.
Fibreglassed Concrete Pool vs. Fibreglass Pool
Fibreglassed Concrete Pool
- Construction Method: Existing concrete shell covered with fibreglass layers.
- Custom Shapes: Retains original shape of the concrete pool, which may be bespoke or more complex than standard fibreglass shells.
- Installation Time: Typically quicker than building a new pool from scratch, but can still be an intensive process depending on the condition of the concrete.
Fibreglass Pool
- Construction Method: Pre-fabricated fibreglass shell installed into an excavated hole.
- Shape and Size: Generally limited to manufacturers’ available moulds, though custom options do exist at a higher cost.
- Installation Time: Often very quick because the shell is pre-made, but ground preparation must be precise.
Both options have unique pros and cons. If you already have a concrete pool and want to upgrade without installing an entirely new structure, applying fibreglass over concrete pool surfaces can be an excellent solution. For new builds, a prefabricated fibreglass pool may be more cost-effective and faster to install.
