A Step-by-Step Guide to Fiberglass Pool Installation

Are you dreaming of a backyard oasis? Fiberglass swimming pools are popular for their durability, sleek look, and relatively fast installation process. Here’s a step-by-step guide to help you understand what goes into installing a fiberglass pool, from site preparation to the finishing touches. Knowing each stage will make the process smooth and easy for you and help you feel more confident about transforming your backyard.

Step 1: Site Preparation

Before anything else, Pools By Design will visit your property to evaluate the best location for your pool. This involves checking for any underground utilities and measuring the area to ensure the pool fits perfectly. Once that’s done, the site is cleared, and the space is marked for digging.

Step 2: Excavation

Once the site is prepped, it’s time to dig. Excavation is when our crew digs out the area where the inground fiberglass pool shell will sit. The hole must be precisely measured and shaped to fit the pool shell exactly. A well-excavated area ensures the pool sits level and stable, so this step is crucial.

Step 3: Base Layer and Setting the Pool Shell

After excavation, a gravel or sand base layer is added to the hole. This base helps cushion the pool shell and provides a stable foundation. Next, the fiberglass pool shell is carefully lowered into the hole using a crane. This part requires precision, as the shell needs to sit level on all sides. Our crew will adjust it as necessary to ensure a perfect fit.

Step 4: Plumbing and Backfilling

With the shell in place, plumbing for the pool’s filtration and heating system is installed. The pipes are connected to the pool’s skimmers, drains, and returns. Once the plumbing is set, the backfilling process begins. This involves filling the empty space around the pool shell with sand or gravel, helping it stay secure and level.

Step 5: Filling the Pool and Installing the Equipment

As the backfilling is completed, the pool is filled with water. The water’s weight further stabilizes the shell and allows for any final leveling adjustments. Then, the equipment like the pump, filter, and heater are installed and connected to the plumbing system.

Step 6: Final Touches and Landscaping

With the pool structure complete, it’s time for the finishing touches. This includes installing the pool’s coping (the material around the edge of the pool), any surrounding pool decking, and landscaping around the pool area. This final step personalizes your pool and makes it blend beautifully with the rest of your yard.
