So, you’ve made the big and exciting decision to invest in your own in-ground pool at home.  Your next big decision to make is ‘concrete vs fibreglass’.  As leading concrete pool builders in Byron Bay we can tell you that concrete offers an abundance of flexibility in design. However, let’s look at the high level facts for each:

Concrete Pools are long lasting, fully customisable, prices range between $30,000 – $80,000 and they can take up to 3 months from inspection to completion.

Fibreglass Pools are durable, come from pre-made designs, prices range between $30,000 – $85,000 and they can take up to 5 weeks from inspection to completion.

Both are great options and there is no clear winner so it’s important to first consider which is more suited to your own personal needs.  Use the below steps to help you determine which option might be more suitable for you:


  1. First create a vision board so that you can determine how you want your pool to look.  Think about colours, textures, water features and surrounding areas.  Get clarity on what your dream pool looks like and use that vision as a starting point to work from.
  1. Determine how much time you have before you want to be swimming.  If you have already sent out invites to your pool party happening next month, fibreglass will be the way to go.  If you’re in the middle of winter and want to be swimming by summer, concrete will still be a viable option for you.
  1. Think about how much space you have and how big you want your pool to be. Remember you don’t want your pool to overrun the rest of your yard. Keep it in proportion and make sure you leave adequate space for the garden. If you have an awkwardly shaped yard, you might not be able to find a pre-made fibreglass pool to suit it.  And because fibreglass is transported by road, it is limited to approximately 4.2 metres.  Consider the size of your yard, and also logistics around using a crane to lift the pool shell off the truck and into the desired area.
  1. Another very important factor is the condition of your soil. Unstable soil can lead to concrete pools cracking. Fibreglass pools are more durable when it comes to earth movements and in this case would be the best option. If you’re unsure of the condition of your soil, you can arrange for a soil tester to come to your premises and take samples away for analysis. This process can be completed within a week and should be shared with your pool builders so that they can plan a suitable installation process.  Feel free to contact us at Byron Bay Pools if you’d like help arranging your soil test.


  • Concrete pools are fully customisable.  So you can really bring your vision board to life with the ability to decide on size, colour and shape.  They are perfect for creating natural pool-scapes or blending the style into existing landscape designs.  You can also include custom additions into your design such as ledges, alcoves, steps and swim-outs.
  • You have a wide selection of interior surface options including pebblecrete, jewels4pools, painted interior (less common these days), or even a fully tiled pool interior.  All of these interior options can last between 20 to 30 years before needing to be replaced.
  • Depending on the interior surface you decide on, you should keep in mind that pebbles and tiles are more prone to growing mould and bacteria. However, with the right level of maintenance and regular testing of your pool water you can avoid this easily.
  • As concrete pools are built from scratch on-site, you will need to expect the construction to last anywhere from 4 – 6 weeks depending on the complexity of your pool design. However, the flexibility and customisation of a perfect concrete pool may just be worth the wait.
  • Thanks to reinforced steel and concrete combined, concrete pools are structurally stable.


  • Fibreglass pools can be more affordable.  As the pools are pre-fabricated and come with the gelcoat interior, less time is required building, installing and surfacing which can end up approximately 10% cheaper. However, as these are prefabricated the flexibility in design will only extend to the options available to each pool builder.
  • Installation can take up to 3 weeks (up to 5 weeks for the full start-end process).  This means you’ll be enjoying your pool a tad sooner.
  • Pool temperature is normally warmer than concrete pools as fibreglass acts as a natural insulator.  This also means you won’t have to spend as much time or energy heating the pool.
  • Fibreglass pools are pre-made which means your options are limited and you can’t be creative with the style, shape and size.  However, you can customise your pool with water features, tanning ledges, tiles, lighting and finishes.
  • Gelcoat interior surface is smooth to touch and resistant to scratches, UV and treated water.  The interior lasts 10-15 years and can be rejuvenated to bring it back to looking as new.  Steps and tanning ledges have a convenient anti-slip texture that also feels quite smooth to touch.
  • Repairs to a fibreglass pool shell can be a costly exercise, so do take this into consideration should you experience cracks from earth movement.


Before making your final decision, arrange to view some actual pools so that you know exactly what to expect for either option. There’s nothing like being able to touch, feel and see the difference in person. If you head over to our gallery of concrete swimming pool designs you will see how unique each pool is thanks to the flexibility in the material.
