Concrete vs fibreglass pools

Concrete vs fibreglass pools: Hobart pool builder edition

If you’re thinking about purchasing a pool, one of the main considerations for the project will be the materials you choose to build it with. If you haven’t given it much thought, it can seem like a daunting decision to make. With each material offering its own advantages and disadvantages, it can be difficult to know what material will work best for you. To help you make the right choice, we’ve put together the complete guide on concrete vs fibreglass pools. We’ll dive into the benefits and the drawbacks of each pool, analysing and comparing their differences.

Concrete pools

Concrete is a mix of water, cement, sand, and coarse aggregate. A concrete pool shell is created by spraying either gunite or shotcrete onto a reinforced support frame. Gunite is a dry mix of concrete combined with water in a large sprayer. Shotcrete on the other hand is already wet before it’s applied. Both of these application methods produce the same final result, providing a smooth, natural feel to your concrete. After the concrete has been sprayed on, it needs time to strengthen. Over time, it becomes harder and stronger in a process called curing. As a concrete pool builder in Hobart, we are consistently curing concrete. For a typical concrete pool shell that we install, this may take around 28 days.

Advantages to concrete pools

Design flexibility
The shape that you choose to design your pool is completely flexible and customisable when you opt for a concrete pool. Unlike a prefabricated fibreglass pool, you can choose to design your pool in whichever way you would like. You also have complete control over the colour options, as well as any additional features you may want to add including ledges, alcoves and swim-outs.

Aesthetic appeal
The look of a concrete pool is also very hard to beat. With so many appealing finish options available, concrete pools are known for their aesthetic value. From various stone and pebble tiles, there are thousands of possible designs that will bring your pool a sense of style and opulence.

Strength and durability
Concrete pools are also known for their strength and durability. From a structural point of view, they are extremely hard to damage and are not prone to the common warps, bulges and breaks that fibreglass pools experience over time. As a concrete pool builder in Hobart, we have full faith in the strength and structural integrity of our pools.

Disadvantages to concrete pools

They take longer to install

Concrete pools can take longer to install than a typical fibreglass pool. Fibreglass pools simply need to be installed into a hole in the ground, whereas concrete pools need to be physically built within the hole. It also takes additional time for the cement to cure. However, an extra month in waiting time is definitely worth it in the long run if you’re going to receive a high-quality concrete pool. 


Concrete pools are also generally more expensive than fibreglass pools. They are usually more detailed in their custom designs, which takes more time and therefore costs slightly more than an average fibreglass pool. However, you get what you pay for in terms of quality, design and craftsmanship. A concrete pool costs more than a fibreglass pool because it’s more customisable, durable and better looking. 

Fibreglass pools

A fibreglass pool is a single one-piece structure made from fibreglass that is installed into a hole in the ground. Fibreglass pools come in many different shapes and colours, with options available to suit everyone. However, these fibreglass pools come pre-fabricated in different ranges and models, meaning that they cannot be customised too much beyond their existing design.

Advantages to fibreglass pools

Slightly cheaper than concrete pools

Fibreglass pools cost slightly less to install than a concrete pool. The materials used are cheaper, and the labour time is reduced due to the ease of dropping the prefabricated fibreglass shell into a hole. If the price is the most important factor for you, then a fibreglass pool may be for you. Just ensure that you factor in all of the considerations before choosing the cheapest option. 

Quicker installation time

On average, a fibreglass pool installation may take around one month to two months, whereas a concrete pool could take up to 3 months or more depending on the scope of works. Most of the work manufacturing the pool is done in a factory so by the time it arrives at your house, it’s ready to be installed. 

Disadvantages to fibreglass pools

Limited in customisation

As they come pre-fabricated, fibreglass pools are limited in their shape and colour options. You have to choose from a range of models rather than designing each aspect of your pool as you would with a concrete pool. If you’re looking for complete control over your pool design, a fibreglass might not be the option for you. 

Access issues

In order to install your fibreglass pool, it will need to be transported into your backyard. Depending on the size of your pool and the orientation and space available in your backyard, it can be a challenge to carry a giant pool shell over your fence and install it. Installers will often require a crane to lift the shell over the roof of your house if access is limited. This can also result in additional costs. 

Strength issues 

Fibreglass pools often experience warping due to the shells being pre-fabricated. They may not sit in the ground as perfectly as the pool builders would like. This causes issues with bending, bulging and warping during the backfill process. As concrete pools are built with a solid material directly into the shape of the hole, they don’t experience these issues.
