Fiberglass Pools vs Concrete Pools: Which is the Best Investment?

I am very often asked by customers and friends to compare fiberglass pools with concrete pools. I know that when it comes to choosing the best pool for your investment, the decision between fiberglass and concrete pools can be challenging. Both have their unique advantages and considerations, so let’s dive in and explore the benefits and drawbacks of each option to help you make an informed choice.

1. Installation and Construction

Fiberglass Pools: Fast and Efficient

Fiberglass pools are pre-manufactured in factories before arriving at your property. The installation process involves digging a hole, setting the pool in place, and backfilling around it. Compared to concrete pools, this process is significantly faster and can often be completed in a matter of days. Moreover, the smooth surface of a fiberglass pool inhibits algae growth, leading to lower maintenance requirements and chemical usage. I know very well both the installers of polyester pools and the teams that comprehensively deal with the construction of concrete pools. There is no denying that the assembly of a polyester pool is definitely faster and easier. You do not need such professional skills and specialized equipment as in the case of a concrete pool.

Concrete Pools: Customizable Masterpieces

You can choose from many sizes and shapes of fiberglass pools. Sometimes I have the impression that this choice is too wide for some manufacturers and it’s hard to decide with dozens of designs to choose from (Read my tips on choosing the optimal model of a polyester pool). But still, if you have very individual expectations as to the shape, stairs, seats, etc., then the construction of a concrete pool will allow you to fully implement them. Since concrete pools are constructed on-site, you have the freedom to design any shape, size, or depth you desire. Concrete pools are an ideal choice if you have a uniquely shaped backyard or specific design preferences.

2. Durability and Maintenance

Fiberglass Pools: Low Maintenance Wonder

Fiberglass pools are incredibly durable and can withstand various weather conditions without cracking or fading. The smooth, non-porous surface prevents algae from adhering to the pool walls, reducing the need for extensive cleaning and chemical treatments. While they may require occasional resurfacing after several decades, overall maintenance costs for fiberglass pools are relatively low. Every pool needs to be looked after. I have seen both polyester pools and concrete pools that were in a dilapidated state. I have also seen those that were very well made and installed, which looked very good with little effort and financial resources.

Concrete Pools: Strength and Longevity?

Concrete pools are known for their strength and longevity. With proper construction and regular maintenance, a well-built concrete pool can last for decades. However, the porous nature of concrete can make it more susceptible to algae growth, resulting in higher maintenance requirements. Additionally, over time, concrete pools may develop cracks due to ground movement or freeze-thaw cycles, necessitating repairs. I always thought a concrete pool was more durable and solid. After all, concrete is concrete. Before I connected my professional life with fiberglass pools, I did not think that they could be so durable and long-lasting. Many times I had to deal with difficult situations during the unloading of polyester pools, their assembly or service. I rubbed my eyes many times in amazement how resistant to damage and external factors a well-made polyester pool can be.

3. Cost Considerations

Fiberglass Pool is cheaper to make than a concrete pool

Despite the constantly rising prices on European markets, the price differences between the construction of a polyester and a concrete swimming pool are still significant. The amount of work, materials and specialist knowledge make the final price of a concrete pool several dozen percent higher.

4. Environmental Impact

Fiberglass Pools: Eco-Friendly Option

Fiberglass pools have a lower carbon footprint compared to concrete pools. The manufacturing process of fiberglass pools consumes fewer resources and produces less waste. Additionally, the reduced need for chemicals and lower energy consumption during operation make them a more eco-friendly choice. The production of concrete and the construction process for concrete pools can be more resource-intensive and generate more waste. Additionally, the need for more chemicals to maintain water quality can have a higher impact on the environment.


Certainly, the topic is inexhaustible and many more issues can be considered. It is important that you form your own opinion and your choice is fully conscious. Because it is your investment and the satisfaction of making and implementing it will also be yours. If you want my opinion, here’s what comes to mind. Such things as the construction of dpmu, swimming pool, finishing the apartment are one of the largest and very time-consuming projects in our lives. I believe that technological possibilities are so advanced today that it is worth shortening the time to do these things in order to be able to enjoy them longer and more fully. Therefore, I am fully satisfied with my investment in a polyester pool and I think it is a great solution as a garden pool.
