Fiberglass or Concrete Pool: Which One Is Right for Your Bay Area Home?

Installing a pool is a major investment — and choosing between a fiberglass pool or concrete (gunite) pool can feel overwhelming. At Bay Scenery, we’ve helped countless Bay Area homeowners consider the fiberglass vs concrete pool debate to weigh the pros and cons of each type to find the best fit for their budget, lifestyle, and backyard space. The fiberglass vs concrete pool decision is crucial for homeowners wanting the best match.

Making the Right Pool Choice for Your Garden

At Bay Scenery, we specialize in designing and building both pool types — and we’re here to help you decide which option is best for your lifestyle, yard, and budget. When it comes to choosing a pool for your backyard, two popular options are fiberglass pools and concrete/Gunite pools. While both types of pools have their own set of benefits, there are also some significant differences between the two in the fiberglass vs concrete pool comparison.

One of the main differences between fiberglass pools and concrete/Gunite pools is the material they are made of. Fiberglass pools are made of a moldable and durable fiberglass material. Concrete/Gunite pools are made of a mixture of cement, sand, and water (Gunite) that is sprayed onto a steel rebar framework.

One advantage of fiberglass pools is their ease of installation. Because they are made in a factory and delivered to the site in one piece, fiberglass pools can often be installed in as little as a few days. In contrast, concrete/Gunite pools require a more labor-intensive installation process. This process can take several weeks to complete in the fiberglass vs concrete pool installation timeline.

Fiberglass pools are also generally easier to maintain than concrete/Gunite pools. The smooth surface of a fiberglass pool is less prone to algae growth and staining, and it is easier to clean. In contrast, the rough surface of a concrete/Gunite pool can harbor algae and other contaminants, and it may require more frequent cleaning and chemical treatment to maintain water balance.

In terms of durability, both fiberglass pools and concrete/Gunite pools are long-lasting options. Fiberglass pools are resistant to cracking and chipping, and they can last for decades with proper care. Concrete/Gunite pools are also highly durable, with the potential to last for several decades, although they may be more prone to cracking and other forms of damage if not properly maintained.

Cost

When it comes to cost, there is generally a wide range for both fiberglass pools and concrete/Gunite pools. According to a study by HomeAdvisor (https://www.homeadvisor.com/cost/swimming-pools-hot-tubs-and-saunas/inground-pool/), the average cost of a fiberglass pool ranges from $20,000 to $40,000, while the average cost of a concrete/Gunite pool ranges from $35,000 and $65,000. However, it is important to note that these costs can vary significantly depending on the specific features and size of the pool, as well as other factors such as location and labor costs.

In conclusion, fiberglass pools and concrete/Gunite pools are both popular options for backyard swimming pools, each with their own set of benefits and disadvantages. Fiberglass pools are generally easier to install and maintain, while concrete/Gunite pools offer more customization options and are highly durable. The best choice between fiberglass vs concrete pool types will depend on the specific needs and preferences of the homeowner.
