Planning your dream backyard pool, one of the most common questions is, "How long will it take?" If you're weighing concrete vs fibreglass pools, understanding the installation timeline is crucial. While both offer stunning results, their build processes are very different—each with its own pace, stages, and potential delays.

This article dives deep into the installation timelines of fibreglass and concrete pools, comparing their construction stages, time estimates, and what can speed things up—or slow them down.

Understanding the Basics: Concrete vs Fibreglass Pools

Before jumping into the timeframes, let’s briefly explore the core differences between the two types of pools.

Fibreglass Pools

• Pre-moulded shells delivered in one piece

• Installed in the ground using a crane

• Smooth gelcoat finish

• Limited design flexibility (but fast turnaround)

Concrete Pools

• Custom-built on-site

• Fully customizable in size and shape

• More durable in the long term

• Higher time and cost investment upfront

These structural differences have a huge impact on installation timelines. Let’s break it down.

Fibreglass Pool Installation Timeline

Fibreglass pools are often favoured for their speedy installation. Since the shell is pre-manufactured off-site, there’s no need for curing or complex on-site construction.

Typical Installation Time: 2 to 4 weeks

Here’s a step-by-step look:

1. Design & Permits (1–2 weeks)

• Choose your pool shape and size from available models.

• Apply for necessary council or municipal permits.

• Site inspection and approval timelines may vary by region.

Note: In some cases, this stage can take longer due to council delays or zoning issues.

2. Excavation (2–5 days)

• The hole is dug according to the shell dimensions.

• Soil type and site access can influence duration.

3. Pool Shell Delivery & Installation (1–2 days)

• The pre-made fibreglass shell is craned into position.

• Base leveling and shell positioning are done quickly.

4. Plumbing & Backfilling (3–5 days)

• Plumbing and filtration systems are connected.

• The shell is backfilled and secured.

5. Coping, Tiling & Surrounds (1–2 weeks)

• Installation of tiles, paving, decking, or landscaping.

• Depending on your design choices, this can be fast or more detailed.

Final Touches & Handover

• Electrical systems are connected.

• Water is added, and chemical balance is adjusted.

What Can Slow It Down?

• Rain and weather delays

• Permit approvals

• Poor access to the site

• Shell supply shortages

Concrete Pool Installation Timeline

Concrete pools, while customizable and durable, come with a significantly longer build time due to their complexity and curing requirements.

Typical Installation Time: 8 to 12 weeks (can extend to 16+ weeks)

Let’s walk through the process.

1. Design & Engineering (2–3 weeks)

• Tailored design consultations to create your custom pool.

• Engineers may need to assess soil conditions and prepare detailed plans.

2. Permits & Approvals (2–4 weeks)

• More paperwork is often required for concrete pools due to custom designs and site-specific engineering.

3. Excavation (3–7 days)

• Similar to fibreglass, but may be more involved for complex shapes or deeper pools.

4. Steel Reinforcement & Formwork (1 week)

• Steel rebar is installed to create the pool’s skeleton.

• Formwork is set up for concrete pouring.

5. Concrete Spraying & Shaping (1–2 days)

• Shotcrete or gunite is sprayed and shaped.

• This stage is fast but messy.

6. Curing Period (4 weeks minimum)

• This is where time really adds up.

• Concrete needs at least 28 days to cure properly for strength and integrity.

Pro Tip: Rushing this stage compromises structural durability.

7. Waterproofing, Tiling & Coping (2–3 weeks)

• Finishing touches like tiling, waterproof membrane, coping stones, and surrounds are applied.

8. Plumbing, Electrical & Handover (1 week)

• All systems connected and tested.

• Final water fill and balancing.

What Can Slow It Down?

• Weather (especially during concrete curing)

• Custom design changes mid-project

• Permit delays

• Skilled labour shortages

Concrete vs Fibreglass Pools: Installation Time Comparison at a Glance

Which Pool Type is Right for Your Timeline?

The decision between concrete vs fibreglass pools depends on more than just installation time—but it’s a major factor, especially if you’re trying to swim by summer!

Choose Fibreglass if:

• You want a pool installed quickly

• You’re happy with standard shapes and sizes

• Your site is easily accessible for crane delivery

• You want a smooth, low-maintenance finish

Choose Concrete if:

• You want a fully customized design

• Your site has unique challenges (slopes, small spaces)

• You’re not in a rush and are planning long-term

• You want a luxurious, high-end look

Can a Concrete Pool Be Installed Faster?

Technically yes—but usually not without cutting corners. Some builders may claim faster timelines for concrete pools, but that often means reducing curing times, which can impact the pool’s longevity and surface quality.

It’s always smarter to invest in proper construction standards, especially with something as permanent as a concrete pool.

Conclusion: Concrete vs Fibreglass Pools – Installation Matters

When comparing concrete vs fibreglass pools, installation time is one of the biggest differentiators. Fibreglass wins hands-down for speed, often going from dig to dip in under a month. Concrete pools, while slower, offer unmatched customization and durability if you’re willing to wait.

Your decision should balance time, budget, and long-term goals. Whether you’re after quick summer fun or a luxurious backyard showpiece, knowing what to expect in terms of installation time can help you plan smarter—and swim sooner.
