What are the Key Steps for Installing a Fiberglass Pool?

Many people want their own backyard swimming pool oasis, but dread the often times length process of installation. Fiberglass swimming pools offer a quick installation option that is gaining huge popularity in New Jersey. However, to guarantee a seamless and long-lasting installation, it requires meticulous preparation before execution. Every phase, starting with site preparation to final touches is very important in producing a magnificent, durable fiberglass pool that lasts a lifetime. This post will discuss the essential requirements for building a fiberglass pool, giving you the required knowledge to transform your backyard into an aquatic paradise.

Prepare the Site and Dig

Preparing the location for a fiberglass pool installation is a critical step in ensuring a timely installation as well as the pool’s stability and lifespan. The procedure starts with clearing the site of any existing trees, large plants, debris, or buildings that may interfere with the excavation.

Steps to install a fiberglass pool

Once the hole has been dug, also referred to as excavated, a base layer of compacted gravel or crushed stone is placed down to give a sturdy and robust foundation as well as to provide for proper drainage underneath the fiberglass shell. At this point, your installation crew will ensure that the hole is to the right elevation and size depicted in the zoning and construction plans.

Positioning & Distribution

The proper delivery and placing of the pool shell, also known as the setting of the pool, is the next critical step in building your fiberglass swimming pool. Well-executed transport guarantees that the pool arrives intact and ready for installation, with no damage or misalignment. The placement of the pool on the prepared base is equally important since it influences the pool’s levelness and general alignment with the surrounding landscape. Improper alignment can result in uneven water distribution, early structural damage, and a less than satisfactory pool experience.


Backfilling the fiberglass pool shell properly provides the essential stability that prevents settling or sinking. The excavated area around a fiberglass pool is filled with crushed stone and soil to ensure the pool’s sturdiness, increased lifespan, and general performance. It also helps maintain the pool’s shape and prevents cracks or warping caused by uneven pressure distribution. Additionally, well-compacted backfill enhances soil drainage, allowing water to escape and preventing hydrostatic pressure, or pressure from underneath the pool shell, from damaging the pool or its surrounding structure.

Plumbing Installation

Marking and cutting precise locations for skimmers, returns, and main drains (or side wall suctions) are done prior to setting the fiberglass pool shell. These locations are carefully determined by considering desired water flow and equipment placement. Next, use rigid PVC and solvent cement for secure, leak-proof connections. Heat-bend pipes or use sweep elbows if necessary to maintain smooth, gradual turns for optimal hydraulics. Finally, pressure test the entire equipment system before burying it, ensuring a stress-free pool experience.

Electrical Work

Leaving this critical stage to skilled specialists ensures a worry-free, code-compliant pool experience. A licensed electrician will follow all safety requirements and municipal laws to ensure your pool is safe and efficient. These professionals evaluate your current electrical panel capacity and decide whether improvements are required to manage the added demand from the pool equipment. They will then run wiring through previously installed watertight conduit to the specified equipment location from the panel, followed by proper grounding and connection of pumps, filters, and lighting with protected outlets for additional safety.

Filling & Balancing

Your new fiberglass swimming pool will be filled via water tanker the day of installation. This will ensure its will not shift or move once placed in the hole. Using a tanker also provides better balanced water than what often times comes from the homeowners hose. Unbalanced water promotes the spread of harmful bacteria, causing potential health risks like eye or skin irritation. Also, it has the potential to corrode a pool’s surface, shortening its lifespan and necessitating costly repairs. Monitoring and adjusting the pH, sanitizer levels, and essential balancers like calcium keeps the water in perfect harmony, ensuring everyone can take the plunge with confidence and relish the refreshing comfort of their sparkling new oasis.

Decking & Surroundings

Fiberglass pool placement entails more than simply the shell’s location. Decking as well as its surroundings play a crucial role in both functionality and aesthetics. Place the pool in such a way that it receives the most sunlight during your primary usage hours. Ensure ample room around the perimeter for comfortable deck space, considering lounging chairs, sun umbrellas, and potential future additions like hot tubs. Don’t forget to create walkways for easy entry and exit points, especially near steps or built-in seating. Remember safety regulations regarding fencing and leave enough space for its installation without compromising usable deck area.

The successful completion of a fiberglass pool installation requires a number of carefully planned stages, all of which are essential to the project’s success. Be sure to discuss each phase with your pool builder, ask about any subcontractors who will be involved, and set up a realistic timeline for installation. As with any swimming pool, before allowing anyone to use your pool, be sure it’s safe for use.
