The Great Pool Debate
When Perth homeowners start thinking about adding a pool, the first question is almost always the same: fibreglass or concrete? Both have their place, but after years of building pools across the Perth metro area, we've seen first-hand why fibreglass consistently wins on value, speed, and long-term satisfaction.
Here's an honest comparison to help you decide.
Installation Time
Fibreglass: A typical fibreglass pool installation takes 3 to 5 weeks from excavation to swim-ready. Because the shell is manufactured off-site and arrives as a single piece, there's no curing time, no tiling, and no plastering on-site.
Concrete: Expect 3 to 6 months minimum. Concrete pools are built from scratch on-site — excavation, steel reinforcement, shotcrete, curing, waterproofing, tiling, and finishing. Every step depends on weather and trades scheduling.
The verdict: If you want to be swimming sooner rather than later, fibreglass is the clear winner.
Cost Comparison
Fibreglass: Entry-level fibreglass pools in Perth start from around $35,000 to $45,000 installed, with premium options (larger sizes, landscaping, equipment upgrades) ranging up to $80,000+.
Concrete: Concrete pools typically start at $50,000 to $60,000 and can easily exceed $100,000 depending on size, shape, and finishes.
The verdict: Fibreglass offers a lower upfront cost and significantly lower lifetime maintenance costs.
Maintenance and Running Costs
This is where fibreglass pools really stand out. The smooth gelcoat surface is non-porous, which makes a noticeable difference when it comes to ongoing care and costs.
- Less chemical use because algae find it much harder to cling to the smooth surface
- Lower energy bills thanks to the natural insulating properties of fibreglass, which help retain heat
- Less cleaning required as there are no rough or porous areas for algae or calcium to build up
Fibreglass pools are also built for long-term durability and typically come with a lifetime structural warranty, giving you added confidence in your investment.
Over a 20 year period, many homeowners find that a fibreglass pool can save between $20,000 and $40,000 in maintenance costs compared to concrete.
Design & Customisation
Concrete has historically had the edge here — you can build any shape, any depth, any feature. However, modern fibreglass manufacturing has closed the gap dramatically.
Narellan Pools (our manufacturing partner with over 50 years of expertise) offers six distinct pool ranges with multiple sizes, built-in seating, splash decks, and entry steps. Each design has been engineered for structural integrity and aesthetic appeal.
The reality is that 90% of Perth homeowners will find exactly what they want in a well-designed fibreglass range.
Perth's Sandy Soil Conditions
Perth's sandy, often reactive soil conditions are another reason to consider fibreglass. A fibreglass shell is a single, flexible structure that can handle minor ground movement without cracking. Concrete, being rigid, is more susceptible to cracking in reactive soils — and repairs are expensive.
Our Recommendation
For most Perth families, fibreglass is the smarter choice. It's faster to install, easier to maintain, gentler on your budget, and built to handle our local conditions.
