Concrete Pools V Fiberglass Pools, What’s the best type of pool to build?

Building a pool is a big decision. One of the most common questions we are asked is “What type of pool is best to build for my home, a Concrete Pool or a Fibreglass Pool?” 

The truth is, there is no ‘better’ type of pool. They both have differences, each with their own unique positives and negatives. So the real question should be “Which type of pool is best for YOU?”

So, let’s break it down so you can understand the pros and cons to help you identify what pool is going to be best for your situation.

Fibreglass Pools Pros

Fibreglass pools come off the shelf and can be a simple, quicker solution. Fibreglass has an advantage that you can see your pool design before you purchase it, but has limitations to site conditions like sloping sites, difficult access or yards that receive water overflow. 

Fibreglass Pools Cons

Unfortunately for fibreglass they have a difficult time holding down Hydrostatic pressure during intense rain and can suffer catastrophic failure if the height of the pool has been assessed too low to the ground or! Sub- Terranean drainage systems have not been constructed under the floor of the pool shell to allow for drainage to flow to the relief valve (Hydrostatic Valve)

However, this does not mean Fibreglass is bad. They can be a great solution, however, the problem we see is that too much focus is placed on the shell construction and NOT enough on the installation process.

  Overall, If you are considering a fibreglass pool, ensure your contractor really understands the principles involved with Hydrostatic pressures. Be very sure to examine your chosen contractors depth of knowledge before you select your company.


Next, let’s take a look at concrete pools…

Concrete Pool Pros

Concrete pools are an entirely different method of construction with a long list of advantages. Concrete pools are not subject to the same effects fibreglass suffer as they are built on 100-150mm of 20mm drainage gravel that allows for water pressure to flow easily and quickly to the main drain where your hydrostatic valve is placed.

The site conditions don’t impact the possibility of construction any site anywhere is possible for a concrete pool. Design options are endless, custom-built to suit the homeowner and their family.

Concrete Pool Cons

The main drawback of concrete pools is the cost. On average, a concrete pool can set you back 10-20% more than a fibreglass pool. There is also a slightly longer installation time when working with concrete because of the time required to poor, shape and set. 

  Overall, concrete pools offer a lot of advantages over fibreglass. Although the cost to install one is slightly higher than its alternative, in almost all cases – it is a worthwhile investment. A concrete pool will be a solid lifelong investment that will add to the value of your home for many years to come.



Either pool has the ability to suit the owner, there are some mitigating factors to be considered. But to get the best understanding we always recommend you reach out to a Pool Building to come to your home so they can give you a custom quote and guide you on what type of pool will be best for your needs.
