What is the Process of Fiberglass Pool Installation?

Table of Contents

Fiberglass pool installation has become a popular choice for many homeowners in recent years due to its speed and durability. This process, though technical, is fairly consistent, often leading to a quicker completion compared to other pool types. Here, we will delve into what the pool installation entails, and explain some of the fundamental concepts that you will encounter during the process.

What is Fiberglass Pool Installation?

Fiberglass pool installation is the process of incorporating a pre-manufactured shell made of fiberglass—a composite material made of thin glass fibers embedded in a resin matrix—into a pre-dug hole on a property. This installation method is recognized for its low maintenance, aesthetic flexibility, and quick turnaround time.

Basics of Fiberglass Pool Installation

The basic process of fiberglass pool installation starts with obtaining the necessary permits for the pool installation. Following this, the area where the pool will be placed is excavated. A compacted gravel base is prepared and the fiberglass pool is delivered and set onto the base. Ensuring the pool’s levelness is crucial at this stage.

Afterward, the pool is backfilled and filled with water concurrently to maintain balance. Once the pool is set, plumbing is run and the type of deck—be it concrete or pavers—is decided upon. The process typically takes two to three weeks to complete, depending on the specific conditions of the site and the chosen design. We will discuss more about these processes in the following sections.

Starting the Fiberglass Pool Installation: Permitting Process

Having a permitted plan is critical for a seamless fiberglass pool installation. This plan includes detailed diagrams and specifications of the pool, ensuring that it aligns with local codes and zoning regulations. A well-detailed plan minimizes potential legal issues down the road.

Obtaining Permits for Fiberglass Pool Installation

Obtaining permits requires submitting your plan to local authorities. These permits verify that the proposed pool installation follows the set rules and guidelines, keeping the installation process smooth and hitch-free.

The Role of a Licensed Contractor in Johnson County

A licensed contractor is essential in the fiberglass pool installation process. Besides having the technical know-how, they understand the local permitting process, ensuring the fiberglass pool installation is up to code and professionally done.

Excavation and Dirt Management

After permits have been secured, the next step is the physical transformation of your yard. The process involves excavation and dealing with the excavated dirt.

Excavating the Site for Pool Installation

Excavation involves digging out the space where the fiberglass pool will be placed. It’s important that the excavation aligns with the dimensions of the pool to ensure a perfect fit.

Handling of Excavated Dirt: Hauling off or Grading

Once the hole is excavated, the dirt removed needs to be managed. This may involve hauling it away or grading the yard, depending on the landscape and the homeowner’s preferences.

Preparing the Base

Preparing a solid base for your pool is a vital step in fiberglass pool installation. This base is meant to support the weight of the pool and prevent any structural issues.

Importance of a Well-Prepared Base

A well-prepared base is essential to ensure the longevity and durability of the pool. It serves as a solid foundation, preventing the pool from shifting or cracking over time.

The recommended base for fiberglass pool installation is a half-inch compacted gravel base. It provides the necessary firmness and allows for adequate drainage, supporting the pool’s structural integrity.

Pool Delivery and Placement

After the base is set, the next step is the delivery and positioning of the pool. This stage is crucial in determining the stability and aesthetic appeal of the pool.

Role of the Crane in Pool Delivery

A crane is typically used to transport the fiberglass pool shell from the delivery vehicle to the excavated hole. The use of a crane ensures precise placement and minimal damage to the pool and property.

Hoisting and Setting the Pool: The Key Steps

Hoisting and setting the pool involve moving it over the property and carefully placing it in the excavated hole. This needs to be done accurately to ensure a perfect fit.

Ensuring Levelness: A Critical Aspect of Pool Installation

Once the pool is placed, it’s crucial to ensure its levelness. A pool that’s not level can lead to uneven water distribution and potentially damage the pool structure.

Backfilling and Filling the Pool

Once the pool is in place, the backfilling and filling process begins. These two steps work together to maintain the balance and stability of the pool.

The Backfilling Process

Backfilling involves filling the space around the pool with soil or gravel. It’s a crucial process that helps support the pool shell and prevent shifting.

Filling the Pool Concurrently with Backfilling

The pool is filled with water simultaneously with backfilling. This ensures that the pressure inside and outside the pool is balanced, preventing structural strain.

Running Plumbing and Choosing the Deck

With the pool firmly in place, the next steps involve running the plumbing and choosing the type of deck for the pool. Both steps are crucial for the functionality and aesthetics of the pool.

Running the Plumbing in the Newly Installed Pool

Running the plumbing involves installing the necessary pipes for the pool’s filtration and heating systems. This ensures that your pool remains clean and comfortable for use.

Deck Choices: Concrete or Pavers?

The type of deck chosen for your pool can greatly influence its look and feel. Options typically include concrete or pavers, each offering unique advantages in terms of cost, maintenance, and appearance.

Completing the Fiberglass Pool Installation Process

Once all these steps have been completed, it’s time to finalize the fiberglass pool installation process. This involves opening the pool and understanding the overall time frame for a standard installation.

Opening the Pool: The Final Step

The final step is opening the pool. This includes adding necessary chemicals, starting up the filtration system, and checking everything for proper operation.

Overall, the process for a standard fiberglass pool installation typically takes two to three weeks. However, this can vary depending on specific site conditions, the complexity of the design, and other factors such as weather and permit approval times.


In conclusion, fiberglass pool installation is a complex yet highly efficient process. Its popularity has grown significantly in recent years due to the numerous benefits it offers:

  • Quick Installation: Fiberglass pools typically take two to three weeks to install, much less than concrete pools.
  • Low Maintenance: Fiberglass pools have a nonporous surface, which reduces the growth of algae and reduces the amount of cleaning needed.
  • Durability: Fiberglass is resistant to cracking and chipping, making it a long-lasting choice.
  • Smooth Surface: Unlike concrete, fiberglass pools have a smooth surface, reducing the risk of scrapes and blisters.
