Durability and Longevity
Both fiberglass and concrete pools are built to last, but their lifespan and resistance to wear and tear differ significantly.
Fiberglass Durability
Fiberglass is inherently durable and flexible. It can withstand shifting soil and minor ground movement, reducing the risk of cracking. The gelcoat finish is resistant to corrosion and chemical degradation.
Lifespan:
A fiberglass pool, with proper care, can last anywhere from 25 to 30 years. In some cases, with regular maintenance, the lifespan can exceed 40 years.
Maintenance:
Because the surface is smooth and non-porous, algae buildup is less frequent. That means less time scrubbing and fewer chemicals needed to keep the pool clean and balanced.
Concrete Durability
Concrete pools are incredibly strong once they harden, but their longevity depends heavily on regular maintenance. Over time, the plaster finish wears away and must be redone every 7–10 years.
Lifespan:
A high-quality concrete pool, with proper maintenance and periodic resurfacing, can last 50+ years.
Maintenance:
Concrete pools are porous and can harbor algae if not maintained properly. They require more frequent brushing and balancing of chemicals. Additionally, resurfacing can cost thousands of dollars every 7–10 years.
Customization Options
Customization is often a deciding factor when comparing fiberglass and concrete pools.
Fiberglass Customization
Fiberglass pools come in standardized shapes and sizes manufactured in a factory. While this limits flexibility, it ensures a consistent outcome. There are, however, a range of models to choose from, and you can add features like:
- Swim jets for lap swimming
- Beach entries and tanning ledges
- LED lighting and water features
- Custom decking and landscaping
Concrete Customization
Concrete pools allow for nearly unlimited design possibilities. You can shape the pool exactly how you want. This makes them ideal for homeowners looking to integrate unique architectural elements, built-in spas, waterfalls, vanishing edges, or intricate tile designs.
Concrete also offers a wide range of finish options:

While fiberglass requires significantly less maintenance over time, concrete pool owners can manage the workload with automation systems and professional maintenance contracts.
Environmental and Climate Considerations
Where you live can play a pivotal role in whether a fiberglass or concrete pool is more suitable.
Fiberglass in Cold Climates
Fiberglass pools are well-suited for cold regions because the shells are reinforced to absorb freezing and thawing cycles. However, winterizing is still crucial to prevent pipe damage and water freezing.
Concrete in Cold Climates
Concrete pools must be professionally winterized to prevent cracking from ice expansion. In regions with particularly harsh winters, some homeowners prefer fiberglass due to its resilience against freeze-thaw cycles.
Tropical and Warm Climates
Concrete pools are well-suited to warm climates because they can be customized to include deep ends, shade areas, and built-in water features that help manage pool temperatures. Fiberglass pools also fare well, and in fact, their ability to retain heat can be a plus in moderately warm areas.
Lifestyle Factors to Consider
Pool ownership should enhance your lifestyle and fit your daily habits, entertaining style, and family needs.
Entertaining Potential
Concrete pools, with their ability to be uniquely shaped and combined with spas, lounging areas, and custom tile work, tend to offer larger and more luxurious entertainment spaces.
Fiberglass pools, though often smaller and more uniform, can still provide a great space for gatherings—especially with added tanning ledges, in-pool seating, and LED lighting.
Family-Friendly Features
Fiberglass pools typically have a smoother finish that is friendlier to children’s skin and feet. They also tend to have shallower, safer sections integrated into the design.
Concrete pools can be designed with zero-entry points and safe water depths, but the surface can be rougher without upgrades.
Swimming and Use Frequency
If you’re an avid lap swimmer or plan to use your pool daily, you might consider adding swim jets or creating a lap pool shape. Fiberglass models are available for this, but concrete pools offer more flexible design options if you prefer a dedicated lap area.
Resale Value and Homebuyer Appeal
In real estate, a backyard pool can either boost or reduce your home’s appeal, depending on how well it was built and maintained.

What are the main differences between fiberglass and concrete pools?
Fiberglass and concrete pools differ significantly in terms of construction, customization, and maintenance. Fiberglass pools are pre-molded shells that are manufactured off-site and then installed in a prepared hole. They come in a variety of standard shapes and sizes, which makes them quicker to install and less labor-intensive. On the other hand, concrete pools (also known as gunite or shotcrete pools) are built on-site using a framework, steel rebar, and a concrete spray. This construction method allows for a high level of customization, enabling homeowners to create a pool that fits their exact specifications and landscape needs.
The materials also contribute to differences in surface texture and maintenance. Fiberglass pools have a smooth, non-porous surface that is resistant to algae growth and requires fewer chemicals and less scrubbing. Concrete pools, being more porous, require regular brushing and more frequent chemical balancing to keep the water clean and clear. Additionally, concrete pools can be finished with various materials like tile, stone, or plaster to enhance aesthetics, while fiberglass pools have a fixed finish that can fade or become stained over time if not properly maintained.
Which type of pool lasts longer, fiberglass or concrete?
Both fiberglass and concrete pools are durable, but they have different longevity considerations. Fiberglass pools are known for their resilience and typically last 25 to 30 years or more without major repairs. Because the shell is manufactured in a controlled environment, it is less prone to structural issues such as cracking. However, the color and finish of fiberglass pools can fade over time, especially when exposed to intense sunlight and improper water chemistry. That said, the structural integrity of the pool remains intact, and with proper installation and maintenance, it can provide decades of reliable service.
Concrete pools, when built and maintained correctly, can last even longer—often 30 to 50 years or more. The primary challenge with concrete pools is their susceptibility to cracking due to ground movement, freeze-thaw cycles, or poor construction practices. Regular maintenance, including surface recoating every 10 to 15 years and monitoring for structural issues, is essential to ensure a long lifespan. While they require more ongoing care, concrete pools offer a robust and long-term investment for homeowners who are willing to commit to maintenance and occasional upgrades.
Are fiberglass pools more expensive than concrete pools?
Initial installation costs are often lower for fiberglass pools when compared to concrete pools. Fiberglass pools typically range from $20,000 to $40,000, depending on the size, shape, and additional features such as waterfalls or lighting. Because the shell is pre-made and installation time is shorter, labor costs are reduced, which contributes to their lower overall price. Additionally, ongoing maintenance costs tend to be lower due to the smooth, non-porous surface that reduces chemical use and cleaning frequency.
Concrete pools, by contrast, generally have higher upfront and ongoing costs. Installation can range from $50,000 to well over $100,000, depending on the level of customization, materials used, and site preparation requirements. The on-site construction process is labor-intensive and takes longer, which drives up labor expenses. Furthermore, because of the porous nature of concrete, maintenance costs—such as water balancing chemicals and regular brushing—are typically higher. While the first investment is greater, many homeowners find the customization and long-term durability worth the additional expense.
Which type of pool offers more design flexibility—fiberglass or concrete?
Concrete pools offer the greatest freedom when it comes to design customization. Since they are built on-site, they can be crafted to suit any size, shape, or style. Homeowners can incorporate unique features like rock formations, custom tiling, integrated spas, and intricate water features. This makes concrete pools a popular choice for those looking to create a one-of-a-kind backyard oasis that complements their home’s architecture and landscape. Additionally, the choice of final surface finish—plaster, quartz, or pebble—allows for a high degree of aesthetic customization.
Fiberglass pools, on the other hand, are limited by the molds used by manufacturers. Although improvements in design have expanded the range of available shapes and styles, homeowners are still selecting from pre-fabricated options rather than creating a fully custom design. While some customization in terms of coping, deck design, and additional features is possible, the overall form of the pool is fixed. Fiberglass is best suited for those who want a stylish and functional pool quickly, with less emphasis on completely tailoring the design to their property.
Which pool type requires less maintenance: fiberglass or concrete?
Fiberglass pools generally require less maintenance than concrete pools due to their smooth, non-porous surface that resists algae growth and staining. This means less scrubbing, fewer chemical treatments, and often longer intervals between maintenance tasks. The water in fiberglass pools tends to remain clearer for longer periods, which reduces the reliance on costly pool chemicals and labor-intensive cleaning routines. For homeowners looking for a low-maintenance option that can be enjoyed with minimal effort, fiberglass is often the preferred choice.
Concrete pools require more consistent upkeep because their surface is more porous, which can allow algae and dirt to accumulate more easily. Frequent brushing, regular chemical balancing, and periodic acid washing are necessary to keep the pool in good condition. In addition, the finish of a concrete pool—whether plaster, quartz, or pebble—may need to be redone every 10 to 15 years. While proper maintenance can mitigate these challenges, the nature of the material makes concrete pools more labor and time-intensive compared to fiberglass pools.
Are fiberglass pools prone to cracking or fading?
Fiberglass pools are designed to be highly durable, with cracks being relatively rare if the pool is properly installed and maintained. A high-quality fiberglass shell is reinforced with layers of resin and glass fibers, making it flexible enough to withstand normal ground movement without sustaining structural damage. However, poor installation practices—such as not properly supporting the shell during installation or improper backfilling—can cause stress and lead to cracks. Additionally, exposure to harsh chemicals or extreme water conditions can weaken the gel coat finish over time, potentially causing brittleness or cracking.
Fading can occur with fiberglass pools, especially if they are exposed to prolonged sunlight or if water chemistry is not regularly maintained. Most fiberglass pool manufacturers now use UV-resistant gel coats to minimize fading, but over time, color changes may still become noticeable, particularly in darker shades. This fading is typically a cosmetic issue rather than a structural one and may affect resale value or appearance. To extend the longevity of the finish, pool owners are advised to maintain balanced water chemistry, use appropriate cleaning products, and consider using a pool cover when the pool is not in use.
What factors should I consider when deciding between a fiberglass and concrete pool?
When choosing between a fiberglass and concrete pool, it’s important to consider your budget, timeline, design preferences, and maintenance tolerance. Fiberglass pools often have a lower upfront cost, quicker installation time, and lower ongoing maintenance needs, making them ideal for homeowners who want a cost-effective and hassle-free option. Meanwhile, concrete pools come with a higher price tag and longer installation period but offer unmatched customization in shape, size, and features. If you have a specific vision for your outdoor space and are willing to invest time and money in upkeep, a concrete pool may be the better option.
Equally important is considering your climate, soil conditions, and intended usage. Fiberglass pools are sensitive to ground movement and may not be ideal in regions prone to earthquakes or severe freeze-thaw cycles unless installed with proper support. Concrete pools, while more durable in varied soil conditions, may require additional structural engineering in unstable soil environments. For heavy usage or commercial settings, concrete pools are often more resilient. Ultimately, evaluating your personal priorities—whether it’s aesthetics, budget, ease of maintenance, or longevity—will determine which pool type aligns best with your lifestyle.
