Fiberglass vs. Gunite Pools: Understanding the Differences

When embarking on the journey of pool ownership, the array of choices available can be overwhelming, particularly when it comes to the materials from which to construct your backyard centerpiece. Two of the most popular options on the market are fiberglass and gunite pools, each with a unique set of features that cater to different needs and preferences. In this blog, we’ll explore how these pools differ in terms of installation, maintenance, durability, cost, and customization potential.

1. Installation: Speed vs. Flexibility

Fiberglass pools boast an advantage regarding installation speed. As these pools are factory-manufactured and arrive pre-formed, they can be installed in a matter of days once the site is prepared. This quick turnaround is a major plus for families eager to dive into their new pool.

Gunite pools, on the other hand, offer unparalleled design flexibility. They are not your “out of the box design” like fiberglass, but rather it gives you the upmost in flexibility and creativity in designing your backyard oasis. The construction of a gunite pool is an on-site project that involves creating a steel framework which is then sprayed with a concrete mixture. This labor-intensive process takes time to cure and to add finishing touches.

2. Maintenance: Ease vs. Commitment

Maintenance is a consideration for any pool owner. Fiberglass pools have a gel-coated surface that is non-porous and smooth, making it resistant to algae and easier to clean. This translates to fewer chemicals and less elbow grease to keep the pool clean.

Gunite pools demand a little more attention due to their porous nature, which creates a more susceptible surfaces for algae and bacteria to adhere. As such, they can require additional brushing and chemical treatments to stay clean.

3. Durability: Longevity in Different Coats

Durability is where gunite pools shine. They are known for their robustness and longevity, often lasting decades with proper care. The strength of gunite pools also allows for more intricate and dramatic designs with overhanging and vanishing edges, custom steps, waterfalls and integrated and elevated spas.

While fiberglass pools might not match the lifespan of their gunite counterparts, advances in manufacturing have enhanced their durability. Subject to less wear and tear, fiberglass pools can last for many years, although they may eventually need a new gel coat after a number of years.

4. Cost: Initial vs. Long-Term Investment

The upfront cost of a gunite pool is often higher than a basic fiberglass pool due to the extensive pool construction processes. However, the reduced long-term maintenance costs and durability can counter balance the initial investment over the pool’s lifetime.

In contrast, a fiberglass pool typically has a lower initial price point, but owners should be prepared for the long-term costs of regular maintenance, repairs, and eventual resurfacing all of which adding to the cost of ownership over the years.
