We know it’s tempting to just go with the pool type you can get the soonest—resist the urge! Fiberglass pools are an inground pool option that is both worth the wait and fits a wide array of buyers’ lifestyles. You may have questions: Is a fiberglass pool worth the money? How long do fiberglass pools last? What is the downside of fiberglass pools? In this blog post, we’ll discuss fiberglass pools pros and cons. 


Fiberglass Pools Pros and Cons

The Pros:

  1. Design Options. At one time, fiberglass pool design options were limited. Modern fiberglass pools come in various shapes, sizes, and colors that complement any backyard design. Go sleek and contemporary or free-flowing and laid back – there is a design and size for every situation. You can easily customize them with tilework that matches your personality and aesthetic.
  2. Built-in High-End Features. Fiberglass pool shell designs include some of the hottest trends in inground pools. Depending on your chosen model, many desirable and artful features like tanning ledges, swim-outs, and wrap-around benches are built-in. Elements once considered only for the realm of resort pools, like beach entries (zero entries), are now built into fiberglass pools.
  3. Smooth, Non-skid Finish. Concrete(gunite) inground pools tend to have a porous, rough finish,. and vinyl pools are often very smooth to the touch but can become slippery when wet. With a fiberglass pool, you have a gel coat finish that looks polished and shiny but is non-skid and non-snag! Of course, any pool type can pose a fall risk, so always be careful as you enter and exit the pool!
  4. Durable. Don’t be fooled by the “glass” in the word fiberglass. While not all fiberglass pools are equal, we build Thursday Pools fiberglass pools with nine layers of strength, with both the structure and surface lasting for decades with less maintenance required than other pool types. Non-porous fiberglass inhibits algae and other minerals that break down other pool-type finishes. Whereas a vinyl liner typically needs to be replaced every eight to ten years on average and a gunite pool needs replastering after 10 to 15 years on average, a fiberglass pool can last a lifetime with proper pool maintenance!
  5. Lowest Maintenance. It’s generally accepted that fiberglass pools have the lowest maintenance cost of all three pool types. A fiberglass pool’s ten-year maintenance costs could be around $3,750 on average, whereas other pool types maintenance costs can be much higher. A big part of long-term gunite pool maintenance costs involves steel brushing the surface every week, acid washing an average of every three to five years, and resurfacing an average of every 10 to 15 years. For vinyl liner pools, replacing the liner every five to nine years or so will need to be factored into maintenance cost plans. Because there is seldom a need to resurface fiberglass, and fiberglass pools require fewer chemicals, you can anticipate lower maintenance costs over the pool’s lifetime.
  6. Quick to Install. Vinyl and gunite pools are built on-site and are subject to the elements and potential delays that inclement weather brings to construction projects. Fiberglass pools are constructed in a controlled factory environment. When it arrives at your home, it is ready to be put into place. The process can occur in as few as three weeks during non-peak seasons. Compare that with concrete pools that typically take three to six months to  install and vinyl liner pools that could  take six to eight weeks.
  7. Pet-friendly. Concrete inground pools can be rough on your pet’s paws, and vinyl inground pools can be slick, causing slips or tears when they come in contact with pet nails. The durable, non-skid surface of fiberglass resists scratches and tears from toenails and prevents slipping when your pet attempts to get out of the pool. 
  8. Increased Home Value. As home resale value varies by location and condition, a home with a pool’s resale value also varies by type of pool installed. Because of the lower long-term maintenance costs, fiberglass pools tend to be preferred by homebuyers and can increase the value of your home.
  9. Environmentally More Friendly. Non-fiberglass pools can leach chemicals and rust back into the groundwater. And acid-washing can result in harm to the environment. Fiberglass pools don’t pose these types of environmental problems. If you go with a fiberglass pool manufacturer committed to the environment, you are taking steps to contribute to a greener world.


The Cons:

  1. It’s not a DIY Home Project. We recommend that an independent dealer installs your fiberglass pool. If you go with a non-licensed installer, the performance and durability of your pool can suffer. With a DIY approach,  you may not get to enjoy your pool until you fix all the mistakes. Common problems people have when trying to install a fiberglass pool on their own are getting the pool level and pouring coping around the fiberglass pool. These can be expensive errors to correct.
  2. Size Limits. Gunite and vinyl pools are built on-site, so there is flexibility if you want to go big with your pool. One of the disadvantages of fiberglass pools is that they are generally limited in size and shape by what can be transported from the factory to your backyard. Road restrictions limit the size of a fiberglass pool to approximately 16′ wide x 40′-41’ long.
  3. Customizability. Fiberglass pool designs are surprising in their breadth of features and shapes, but they are pre-built, so the manufacturer’s parameters can limit you. For example, if you have your heart set on building a guitar-shaped pool, you’ll likely need to look into gunite. Additionally, if the fiberglass pool design you want comes with a tanning ledge that you don’t want, you will also need to look at another pool type.
  4. Access/Space for Installation. Because we transport a fiberglass pool shell in one piece to your backyard, you must have backyard access and space. Installers often use cranes and other heavy equipment to get the pool to its destination and this need for access and freedom to move a large object can be a dealbreaker.
