Building Your Dream Pool: Yes or No to Fiberglass?

When considering a new pool build you have a couple of materials in which to chose from. The most common materials being concrete/ gunite, vinyl or fiberglass. Fiberglass pools have been around for a long time. They’re reliable and easy to install, so it’s not surprising we get a lot of questions regarding fiberglass builds. Below we’ve put some of these questions to rest with a simple list describing the pros and cons of fiberglass pool ownership.


  • Quick Install
    The average install for a fiberglass pool is 3-5 days. This means that you don’t have any delays due to construction or unexpected issues that can arise during a concrete or vinyl build. In less than a week you can have a functional pool without any headaches.
  • Growing options
    Over the course of the last decade fiberglass pools have become much more customizable. They have varied shapes and improved options such as: tile, wall color etc. This improves aesthetics and gives fiberglass pool owners a custom look without appearing to be manufactured.
  • Non porous surface
    Fiberglass is the smoothest pool surface option currently available. This is great for two reasons. One, it never wears at your feet the way that concrete pools do. Two, because the surface is smooth and non-porous, algae has nothing to grab a hold of. This reduces algae growth, therefore reducing maintenance and chemical costs.
  • Cost
    Where other pools require resurfacing or replacement liners, fiberglass pools do not. Fiberglass pools are highly durable and require little to no maintenance after initial install. This can save pool owners thousands of dollars and reduce the overall maintenance pool ownership.


  • Repairs
    Although fiberglass pools are quite durable, they don’t come without problem. If repairs are needed, it can be problematic to get an exact color match to your fiberglass shell.
  • Size Limitations
    Concrete/ gunite or vinyl pools can be as big and grand as you desire, but fiberglass pools have limitations due to the way their constructed. The largest fiberglass pool that you’ll find will be around 16’ x 40’. For most pool owners this is a pretty sizable pool, but depending on your needs, this may be a deterrent.
  • Customization
    Over the years more options have become available to customize fiberglass pools, but some options remain limited. Large customized options such as boulders, rock slides and grottos options when considering concrete or gunite builds, but can be problematic when integrating with the shell of a fiberglass pool. Depending on the look and feel of your dream pool, the lack of the available features may be a deal breaker for you.
  • Cost
    In the case of fiberglass pools this can be both a pro and a con. As mentioned above, the cost to maintain a fiberglass pool can be much cheaper. However, the initial cost is not. The up-front cost is comparable to what one would pay for a custom concrete pool with the lack of customization.


Overall, fiberglass pools can be a great option if you’re looking for a lower maintenance pool that you can have up and running quickly, but if your looking for a large pool with a lot of custsomization, fiberglass may not be the material for you.
