Fibreglass vs Concrete: Which Pool Builder Option is Right for You?

Home » News » Fibreglass vs Concrete: Which Pool Builder Option is Right for You?

Choosing to install a swimming pool is one of the biggest investments you can make for your home and lifestyle. Not only does it transform your backyard into a place for family and friends to gather, but it also adds long-term value to your property. One of the first decisions you’ll need to make when working with a pool builder is whether to go with a fibreglass pool or a concrete pool.

Both options are popular across Australia, but if you’re in Darwin, the choice carries extra weight. The Top End climate brings unique challenges, extreme heat, heavy rainfall and seasonal storms, so it’s crucial to work with a pool builder in Darwin who understands how different pool types hold up in these conditions.

At Darwin Pools, we specialise in fibreglass pools. We’ve chosen to focus on fibreglass because it consistently delivers the best results for local families. This blog will explore the differences between fibreglass and concrete, helping you decide which option is right for you.

Installation Time

One of the first questions most homeowners ask their pool builder is, “How long will it take?”

  • Concrete Pools: Concrete pools are built from scratch on-site. The excavation, steelwork, concreting, curing and finishing are a long process, often stretching over several months. Add in wet season delays and it can feel like an endless wait before you’re swimming.
  • Fibreglass Pools: A fibreglass pool shell is pre-manufactured and delivered to site. Once excavation and preparation are complete, the shell can be craned in within a day. The entire project, including council approvals, concreting, fencing and finishing touches can take just a few weeks. While it’s not an overnight job, fibreglass is still considerably faster and less disruptive than a concrete build.

Verdict: Fibreglass pools win for efficiency and shorter timelines.

Durability in Darwin Conditions

  • Concrete Pools: Known for strength, but in Darwin’s climate, concrete is prone to cracking over time. Intense heat and shifting soil can take their toll, leading to costly repairs.
  • Fibreglass Pools: Fibreglass pools are manufactured with flexibility in mind. The gel-coated surface is UV-resistant, smooth and less likely to develop structural issues in the Territory’s conditions. With the right care, a fibreglass pool lasts decades with minimal maintenance.

Maintenance and Cleaning

  • Concrete Pools: Concrete is porous, which means algae and bacteria can cling to the surface. Owners often need to scrub regularly and add more chemicals to keep water clear.
  • Fibreglass Pools: The smooth, non-porous surface of fibreglass naturally resists algae. This reduces the need for harsh chemicals and makes pool maintenance faster and easier.

Comfort and Safety

  • Concrete Pools: The rough surface of concrete can be hard on skin. Kids (and adults) often end up with grazes or scratches after hours of play.
  • Fibreglass Pools: The smooth interior of fibreglass pools makes swimming more comfortable. No sharp edges, no grazes, just a safe environment for family fun.

Design and Customisation

  • Concrete Pools: The big advantage of concrete is flexibility. Your pool builder can design any size, shape or depth you like. However, this comes with higher costs and longer installation times.
  • Fibreglass Pools: Fibreglass pools come in pre-designed shapes, but the variety available today is extensive. From plunge pools to large family designs, lap pools to spa pools, there’s an option for almost every backyard. Add-ons like seating ledges, steps, lighting and water features allow plenty of personalisation.

Cost Considerations

  • Concrete Pools: Concrete pools tend to be the most expensive to install. On top of the upfront cost, you’ll also face higher ongoing expenses for cleaning, maintenance and resurfacing.
  • Fibreglass Pools: Fibreglass is generally more affordable to install and cheaper to maintain in the long run. The durability and low upkeep save money over the pool’s lifetime.

Real Experiences: What Darwin Customers Say

Nothing says more about a pool builder than the feedback of happy customers. Here’s what Brendan Pringle, a Darwin local, had to say:

“Booked our pool in for installation, the whole process was easy, and Gary really spent the time explaining all of our options, provided recommendations which took into account our circumstances rather than just going for the biggest and most expensive sale. We were booked and swimming within a couple of weeks with no issues whatsoever. Cannot recommend these guys enough and have created many great memories with our little ones in the pool already.”Brendan Pringle, Local Guide
