What is a Fiberglass Pool?
A fiberglass pool is a pre-molded, one-piece swimming pool made from reinforced fiberglass material. Unlike concrete pools, which require months of on-site construction, or vinyl liner pools, which need frequent liner replacements, fiberglass swimming pools arrive ready for installation, significantly reducing setup time.
These pools are factory-built using a durable gel coat finish, making them smooth, non-porous, and resistant to algae buildup. They come in a variety of pool styles, from modern rectangular designs to plunge pools and large family-friendly options.
Since they require minimal maintenance, they’re a great choice for anyone looking for a hassle-free backyard swimming pool experience.
Benefits of Inground Fiberglass Swimming Pools
Unlike other types of pools, fiberglass swimming pools stand out for their durability, low maintenance, and fast installation. Whether you want a simple backyard swimming pool or a luxury fiberglass pool design, these pools offer advantages that make them a smart, long-term investment.
1. Fast Installation
If you’re excited to dive into your new inground swimming pool, you don’t want to wait months for construction. Unlike concrete pools, which take 3-6 months to build from scratch, fiberglass pools arrive as a pre-molded shell, ready for quick installation. In many cases, the entire process—from excavation to water fill-up—takes 2-4 weeks.
Since fiberglass pools are manufactured in a controlled factory setting, there are no weather-related delays during construction.
Rain, snow, or extreme heat won’t interfere with the production process. Once d
elivered, installation is straightforward—place the inground fiberglass pool into the pre-dug space, connect plumbing, and add finishing touches.
2. Low Maintenance
No one wants to spend their weekends scrubbing a pool. The smooth, non-porous surface of a fiberglass swimming pool naturally resists algae growth, unlike concrete pools, which have rough, porous surfaces that trap bacteria. This means fewer chemicals, less scrubbing, and easier upkeep.
In contrast, vinyl liner pools require frequent liner replacements, and concrete pools need acid washing, resurfacing, and heavy chemical use. With fiberglass pool designs, you get a hassle-free backyard swimming pool that stays clean with minimal effort.
3. Built for Comfort
Swimming should be enjoyable, not painful. If you’ve ever swum in a concrete pool, you might have scraped your feet or felt rough patches on the floor. Fiberglass pools, on the other hand, feature a soft, gel-coated surface that feels smooth underfoot.
This comfortable texture makes fiberglass pools ideal for families with kids, elderly swimmers, or anyone who enjoys lounging in the water.
You don’t have to worry about rough edges, sharp corners, or irritating pool surfaces. Whether you’re floating, playing, or simply soaking in a built-in spa, the experience is effortless and relaxing.
4. Energy Efficient & Long-Lasting
A fiberglass pool is a long-term investment that saves you money in multiple ways. First, fiberglass retains heat better than concrete pools, reducing energy costs if you use a pool heater. This means your inground fiberglass swimming pool stays warm longer without running your heater constantly.
Second, fiberglass pools are incredibly durable. Unlike concrete pools, which crack over time due to ground movement, fiberglass flexes with the soil, preventing structural damage.
This makes them ideal for regions with temperature fluctuations, where freeze-thaw cycles can cause other pools to deteriorate.
5. Stylish & Customizable
Your backyard swimming pool should match your style, and fiberglass pools come in various designs, sizes, and features to create the perfect outdoor space. You can choose sleek, modern rectangular designs or freeform, resort-style pools with built-in spas and tanning ledges.
Additional features like inground pool lights, waterfalls, and decorative tile finishes allow homeowners to create a custom look that enhances their outdoor space.
Whether you want a family-friendly pool or a luxurious, high-end retreat, a fiberglass pool design can be tailored to your vision.
How Are Fiberglass Pools Made?
The process behind fiberglass swimming pools ensures quality, durability, and precision. Here’s how it’s done:
- Mold Creation: Each pool model starts with a carefully shaped mold to define its structure.
- Gel Coating: A smooth, waterproof gel coat is applied to form the interior finish.
- Fiberglass Layering: Multiple layers of fiberglass and resin reinforce the structure for strength and flexibility.
- Curing & Inspection: The fiberglass pool is left to cure before undergoing a quality check to ensure it meets industry standards.
- Shipping & Installation: The inground fiberglass pool is transported to the homeowner’s site and placed into a pre-excavated area.
How to Choose the Right Fiberglass Pool for Your Backyard
Choosing the best inground fiberglass pool goes beyond looks. Your yard size, usage needs, and climate all play a role in finding the right fit.
Consider Your Backyard Space
Your outdoor space will determine the pool size and shape. A plunge pool or compact fiberglass pool design works well for small yards, while a lap pool or family-sized swimming pool suits larger areas.
Think about placement—do you want your fiberglass pool near the patio for convenience or further away for a private retreat? Also, consider sun exposure, landscaping, and how the pool integrates with your yard.
Think About Who Will Use It
Families with kids may prefer tanning ledges or shallow play areas, while those seeking luxury might enjoy a built-in spa or LED lighting. If you’re into fitness, a rectangular fiberglass pool with a deep end is great for lap swimming.
Climate Considerations
In cold climates, fiberglass pools are more resistant to freeze-thaw cycles than concrete pools, reducing cracking risks. In hot areas, a lighter-colored fiberglass pool helps keep water cooler. A pool cover can help retain heat and reduce evaporation, saving energy costs.
Customization Options
Enhance your backyard swimming pool with features like waterfalls, tanning ledges, built-in spas, or LED inground pool lights. Whether you prefer a sleek modern look or a natural freeform design, there are plenty of customization options.
Budget & Long-Term Value
While fiberglass pools may cost more upfront than vinyl liner pools, they offer long-term savings thanks to low maintenance, energy efficiency, and durability. Looking beyond initial costs will help you make the best investment for years of enjoyment.
Installation and Maintenance of Fiberglass Pools
Installing a fiberglass swimming pool is much faster than concrete pools, which can take months to build. Once installed, fiberglass pools require far less upkeep, making them a low-maintenance choice for homeowners.
Installation: What to Expect
A fiberglass pool can be installed in as little as 2 to 4 weeks, thanks to its pre-molded shell. The process is straightforward and efficient:
- Excavation – The site is carefully dug to fit the inground fiberglass pool, ensuring a secure and level placement.
- Pool Placement – The fiberglass swimming pool is lowered into position using specialized equipment, with adjustments made for proper alignment.
- Backfilling & Plumbing – Sand or gravel is added around the pool for stability while plumbing and electrical systems, including filtration, heating, and inground pool lights, are installed.
- Finishing Touches – Decking, landscaping, and optional features like tanning ledges or built-in spas complete the project.
Maintenance: Keeping Your Pool in Top Shape
Fiberglass pools are easy to maintain, requiring less work than vinyl liner or concrete pools. Routine care ensures a clean and long-lasting swimming experience.
- Regular Cleaning – Skim leaves and debris weekly. Occasionally brush the walls, though fiberglass pools resist dirt buildup better than concrete.
- Chemical Balance – Test and adjust pH, chlorine, and alkalinity levels to keep the water clear and safe. Fiberglass pools require fewer chemicals than other pool types.
- Winterizing – In colder climates, lower the water level, drain plumbing lines, and cover the inground swimming pool to prevent damage from freezing temperatures.
- Filter & Pump Maintenance – Clean or replace filters regularly. Inspect the pump, heater, and pool lights to keep everything running smoothly.
How Much Does an Inground Fiberglass Pool Cost?
The cost of an inground fiberglass pool varies widely based on factors like pool size, depth, additional features, and site preparation. Unlike a simple product with a set price, pool installations involve multiple variables, making it impossible to give a one-size-fits-all estimate.
Instead of relying on generic pricing ranges, it's always best to get several bids from reputable contractors who can assess your specific project.
Our screened swimming pool contractors take into account everything from excavation needs to custom add-ons like inground pool lights, tanning ledges, or built-in spas, ensuring you get a fair and accurate quote that fits your vision and budget.
