What Are Major Differences Between a Concrete and A Fiberglass Pool?

Installing a swimming pool at your home during summers can be a great idea. However, as a homeowner, you should know that there are various kind of swimming pools with two most popular being concrete and fiberglass pools. This article will brief you the differences between concrete and fiberglass pools.

Difference Between Fiberglass and Concrete Pools

  • Durability

Concrete pools are more durable than fiberglass pools due to difference in construction methods and materials being used. With due cleaning, resurfacing and maintenance, concrete pools can last for years. In order to improve longevity of concrete pools, it is advisable to use good-quality surface finishing materials for sealing the material.

Usually, fiberglass pools last somewhere around 15-20 years depending upon the use and maintenance. However, in all cases, a person needs to reapply interior gel finish of the pool every 10 years. The reason why these pools are less durable than concrete pools are that their pool shell is placed on top of the sand or concrete, which makes it vulnerable to cracking as and when ground shifts or settles. Hence, it is important that you know the duration for which you require pool and according to that select the type you want to build.

  • Installation

It is more difficult to install a concrete pool than a fiberglass pool. This is because concrete pools require mesh, reinforcing bars and formwork. The concrete used in making these pools need to be dry-mixed and then should be blown under pressure. This process leads to production of high-quality concrete, which lasts for decades. Hence, building a concrete pool is a long task which may require months to complete.

It is easier to install fiberglass pools since they are available pre-casted from factories and just need to be installed as a single unit. This pool is build on the top of a sand or concrete base which is made inside a large hole. Installation of these pools is relatively easier and can be finished within 3-5 years.

  • Surface

Surface of concrete pools is rather rough and porous and needs chemical sealant for preventing absorption of moisture. The rough surface of a concrete pool can easily attract bacteria leading to algae growth. Additionally, it can cause cuts and scratches if you accidentally hit the pool during swimming, playing or jumping. Hence, you need to be more cautious while using a concrete pool.

In contrast to a concrete pool, fiberglass pools have smooth surface, much like a bathtub. Moreover, the surface is non-porous meaning there are no chances of bacteria growth. However, it is important to know that fiberglass pools can be a bit slippery when wet. Hence, you need to be very careful while using fiberglass pools, particularly when they’re wet.

  • Maintenance

A concrete pool requires more maintenance than a fiberglass pool. You need to do weekly cleaning and scrubbing in concrete pools to prevent algae. In contrast, fiberglass pools need less maintenance due to their smooth surface.


Hope this guide has helped you understand the differences between concrete and fiberglass pools.
