When it comes to installing a residential swimming pool, one of the most pivotal decisions homeowners face is choosing between a fiberglass and a concrete (also known as gunite or shotcrete) pool. A common question that surfaces in nearly every pool buying journey is: Is a fiberglass pool cheaper than concrete? While this seems like a straightforward question, the answer requires a deeper dive into several important factors that influence the overall cost of ownership, installation, maintenance, and long-term value.
In this detailed article, we will examine the complete financial picture of fiberglass versus concrete pools, providing homeowners with expert insights, realistic price comparisons, and useful guidelines to help determine which option offers better value in the short and long run.
Understanding the Basic Difference: Materials and Construction
Before comparing prices, it’s important to understand the structural and manufacturing differences between the two types of pools.
What Is a Fiberglass Pool?
A fiberglass pool is manufactured in a factory using a composite of plastic, reinforced with glass fibers and gel coat. Once completed, it’s transported to the installation site and set into a dug-out hole. The space around the shell is then backfilled and plumbing systems are connected.
Pros of fiberglass pools:
- Quick installation process (often completed in 3–6 weeks)
- Smooth, non-abrasive surface
- Precast parts lead to fewer customization limitations
- Low maintenance due to naturally smooth walls
What Is a Concrete Pool?
Concrete pools are constructed on-site, using rebar reinforcement sprayed with either gunite or shotcrete. Once the structure is formed and cured, it is finished with plaster, pebble, tile, or other finishing materials.
Pros of concrete pools:
- Highly customizable in size, shape, and design
- Can integrate with landscapes, water features, and complex architecture
- Longer lifespan with proper care (often 25+ years)
- Higher initial cost but potentially better ROI over time
Initial Cost Comparison: Fiberglass vs. Concrete
At first glance, it might seem that a fiberglass pool is definitely cheaper than a concrete one. But this isn’t always the case. The upfront cost is influenced by a number of elements.
Typical Price Ranges
Let’s compare a straightforward model of a mid-sized pool (around 16′ x 32′) installed in an average residential backyard with basic decking and landscaping.
| Pool Type | Average Installation Cost | Installation Timeframe |
|---|---|---|
| Fiberglass Pool | $35,000 – $50,000 | 3 – 6 weeks |
| Concrete Pool | $50,000 – $100,000+ | 6 – 12 months or more |
Based on these figures, fiberglass pools are generally cheaper in upfront cost, and they also tend to save on initial labor, materials for finishes, and extended timelines. However, homeowners should be cautious—especially regarding customization and extra features which can change the price dramatically.
Additional Costs to Consider
- Permit fees: Both types require permits, which vary by location.
- Excavation costs: Depending on soil conditions and utility location, excavation costs may be equal.
- Backyard prep: If grading or tree removal is needed, costs increase equally for both pool types.
Long-Term Maintenance Costs: What’s the Real Value?
Many pool buyers overlook long-term expenses, focusing only on the initial investment. However, when determining the overall affordability of fiberglass versus concrete, it’s vital to consider the total cost of ownership.
Maintenance Requirements
| Item | Fiberglass Pool | Concrete Pool |
|——|——————|—————|
| Surface Condition | Smooth, non-porous | Rough, may require acid washing |
| Cleaning | Easier, less algae growth | More effort, requires brushing |
| pH Balance | Easier to maintain | More sensitive to chemical balance |
| Resurfacing Needed? | Rarely (every 15+ years) | Every 7–10 years |
| Chemical Costs | Lower | Higher |
Fiberglass pools generally incur fewer maintenance costs due to non-porous surfaces that resist algae buildup. As a result, less chlorine, fewer cleaning tools, and reduced labor time are required to keep them clean and balanced.
Surface Resurfacing
Conrete pools require regular resurfacing, usually every 7–10 years, depending on maintenance and weather conditions. Each resurfacing can cost $20,000 or more, making this a significant long-term expense.
Fiberglass pool finishes last much longer without degradation or porosity, typically needing only minor touch-ups like seam sealing or localized repairs every 15–20 years.
Energy Efficiency and Heating Costs
Both types of pools can benefit from solar heating, gas heaters, or heat pumps. However, the base temperature retention and conductivity of fiberglass offer a key advantage.
- Fiberglass retains heat better than concrete
- Can reduce heating costs up to 30% in cooler climates
For homeowners living in regions where pools need heating for parts of the year, this heat retention property can significantly affect annual utility bills—making fiberglass a more economical choice in the long term.
Repair and Durability Comparison
Durability of Materials
- Fiberglass pools are highly durable. The gel coat finish resists staining, etching, and cracking better than most concrete finishes.
- Concrete pools, while strong when installed correctly, are susceptible to cracking, especially in areas with expansive soils or seismic activity.
Repair Frequency and Cost
| Repair Type | Fiberglass Pool | Concrete Pool |
|————-|——————|—————-|
| Crack repair | Rare, but can cost $1,000 – $2,500 if needed | Common and could cost $2,000 – $10,000+ |
| Re-plastering | Generally never needed | Every 7–10 years; $30,000 average |
| Tile replacement | Minimal | Common near waterline |
| Leak repairs | Less frequent | Often tied to cracks or plumbing |
The lower rate of repairs and the reduced complexity of fixes in fiberglass pools contributes significantly to their cost efficiency over decades of ownership.
Installation Timeline and Lifestyle Impact
The fiberglass pool installation timeline is much shorter—typically around 3–6 weeks from start to finish. Concrete pools, by contrast, can take anywhere from 3–12 months, depending on complexity, weather, supply chain issues, and contractor availability.
A shorter installation period:
– Decreases labor costs
– Reduces the impact on landscaping
– Minimizes permit and planning fees
This not only results in real cost savings but also less disruption to daily family life and outdoor usability during construction.
Customization and Design Limitations
Because fiberglass pools are premanufactured, they have less flexibility when it comes to unique shapes or exact spatial adaptations. However, modern fiberglass pool manufacturers offer a diverse range of models, many of which include built-in seating, swim-outs, and spas.
Fiberglass Design Options
– Several standard shapes and sizes available
– Custom color and finish options (e.g., quartz-infused gel coats)
– Limited but growing integration with LED lighting, jets, or tanning ledges
– Can include in-floor cleaning systems in some cases
Concrete Pool Advantages in Customization
– Entirely customizable shape
– Seamless integration with surrounding architecture
– Can include infinity edges, grottos, waterfalls, and elaborate deck features
– Full control over plaster colors and textures
While concrete offers more creative design freedom, that creativity comes at a cost—both in initial outlay and ongoing maintenance. For homeowners who prioritize design flexibility, concrete may be worth the higher financial investment.
Return on Investment and Resale Value
If you’re considering a future resale, a pool can either enhance your home’s value or, in some cases, not offer the full cost recoupment.
While both fiberglass and concrete pools add value to a home, concrete can sometimes command higher aesthetic appeal in luxury homes or open-end design contexts. Fiberglass pools typically have lower ROI due to the perception of being prebuilt.
However, given their long-term durability and lower maintenance costs, fiberglass pools may appeal to families looking for hassle-free recreation rather than showcase design features.
Climate and Regional Considerations
Your geographic location can also affect which type of pool provides a more cost-efficient option.
Cold Weather Climates
Fiberglass pools are better suited for climates with freezing winters because:
– The non-porous surface reduces cracking from freeze-thaw cycles
– Simpler winterization process
– Less damage when water is properly winterized
Hot and Dry Climates
Concrete pools can fare well in drier climates where resurfacing and algae management are more frequent concerns, especially if calcium buildup is a risk.
So, while regional climate should not be the sole deciding factor, it can tip the balance depending on average temperatures and how much time is spent using the pool yearly.
Professional Installation Matters
A significant point often overlooked is the **importance of proper installation**—for both fiberglass and concrete pools.
For fiberglass, poor installation practices—such as improper base preparation, incorrect backfilling, or poor plumbing integration—can lead to bowing, cracking, or circulation issues.
For concrete, improper curing, incorrect rebar support, or poor plaster application can lead to uneven finishes, water leakage, and early resurfacing needs.
Investing in experienced installers familiar with your desired pool type can prevent costly future issues and extend the life and performance of your pool.
In Summary: Fiberglass Is Cheaper Than Concrete—But It’s Not That Simple
To answer the original question directly: Yes, fiberglass pools are generally cheaper than concrete pools when comparing initial costs. However, the difference between these two options extends far beyond how much you spend when first installing the pool.
Here’s a final breakdown of how the two pool types compare:
Total Cost Comparison

Final Thoughts: Affordability Means More Than Just the Price Tag
When asking, “Is a fiberglass pool cheaper than concrete?”, the answer isn’t only about dollars and cents. It’s about long-term value, usability, maintenance demands, and how the pool fits into your lifestyle and budget long after installation.
For the average homeowner, fiberglass pools offer a balanced blend of affordability, durability, and ease of maintenance—making them a smart investment in today’s busy, eco-conscious world. If you don’t require full customization and want a pool that provides value for decades, fiberglass is hard to beat.
By considering the overall costs—initial outlay and long-term maintenance—you can now confidently make the decision that complements not only your backyard but your wallet as well.
Are fiberglass pools generally cheaper than concrete pools?
Yes, fiberglass pools are typically cheaper than concrete pools when considering the initial installation cost. This is mainly because fiberglass pools are pre-manufactured and installed as a single piece, reducing labor time and expenses. On average, a fiberglass pool installation can cost between $20,000 and $40,000, whereas a concrete pool can range from $35,000 to $65,000 or more depending on size, design, and additional features. The lower labor costs associated with fiberglass pools also contribute significantly to the overall savings.
However, the upfront cost is not the only factor to consider. While concrete pools are more expensive initially, they offer greater flexibility in design and can be customized to fit a wider range of backyard spaces and personal preferences. Despite the higher initial investment, some homeowners may find the aesthetic and structural benefits of concrete pools to be worth the additional cost, depending on their priorities and long-term plans for the property.
What are the long-term maintenance costs of fiberglass vs. concrete pools?
Fiberglass pools generally have lower maintenance costs over time. The smooth surface of fiberglass is less prone to algae growth, which means less frequent brushing and lower chemical usage. In addition, because fiberglass resists corrosion and staining, homeowners are less likely to face major resurfacing or repair costs, which are common with concrete pools every 7 to 10 years.
Concrete pools require more regular maintenance due to their porous surface, which can encourage algae growth and staining. This often results in higher chemical costs, more frequent cleaning, and the need for acid washing or resurfacing over time. Additional maintenance like coping and tile replacement, plus more frequent pH balancing, adds to the long-term expenses. While fiberglass pools still require consistent upkeep, their overall maintenance burden and associated costs are typically lower than those of concrete pools.
Do fiberglass pools depreciate more than concrete pools over time?
Fiberglass pools generally retain their value well, but they may not add as much to a home’s resale value as a concrete pool in some markets. This is because concrete pools are often viewed as permanent, luxury features that can attract high-end buyers. However, this can vary based on location and buyer preferences, and in many suburban areas with families, a fiberglass pool is still seen as a desirable and low-maintenance backyard upgrade.
Fiberglass pools have the advantage of long-term durability with less repair and maintenance required. This can make them more appealing to buyers who are wary of the potential headaches associated with concrete pools. While some buyers might prefer the custom look of concrete, others may favor the ease of ownership that fiberglass offers. As such, the depreciation or appreciation of a fiberglass pool versus a concrete one will depend on market trends and buyer demand in your specific area.
Is a fiberglass pool as durable as a concrete pool?
Fiberglass pools are extremely durable, especially when installed correctly and maintained properly. The material is resistant to cracking, chipping, and corrosion, which are common issues with concrete pools over time. Fiberglass also flexes slightly with ground movement, reducing the risk of structural damage. With proper care, a fiberglass pool can last 25 years or more and often comes with manufacturer warranties that add an extra layer of protection.
While concrete pools are very strong and can last 30 to 40 years with maintenance, their longevity is largely dependent on the quality of construction and maintenance. Because concrete is porous, it requires more regular upkeep, like replastering every 7 to 10 years, to prevent leaks, cracks, and staining. Fiberglass offers a more maintenance-friendly alternative while still providing durable performance. The key to longevity with either option is working with experienced professionals and following regular maintenance routines.
Can I customize the shape and size of a fiberglass pool?
Fiberglass pools come in a range of pre-molded shapes and sizes, but they are not as customizable as concrete pools. While manufacturers offer various models to suit different backyard layouts and preferences, changes to the design—like deepening the pool or altering the shape—can be challenging and may void warranties or increase costs. However, many modern fiberglass pool models are designed to look more like custom pools, offering attractive, contemporary designs.
Concrete pools offer nearly limitless design options, making them the go-to choice for homeowners who want a unique shape, size, or integrated features like waterfalls or benches. If your focus is on a completely tailored look and maximizing the use of your backyard space, concrete may be the better option. That said, the growing popularity of fiberglass has led to more diverse and customizable options, giving homeowners a broader selection to choose from while still benefiting from the material’s many advantages.
Are fiberglass pools quicker to install than concrete pools?
Yes, fiberglass pools typically take less time to install than concrete pools—often in just a few weeks rather than months. The installation timeline for fiberglass is shorter because the pool shell is manufactured off-site and then delivered and installed in one piece. This eliminates the need for lengthy construction phases such as pouring concrete and waiting for it to cure. In many cases, the entire process—from excavation to filling the pool with water—can be completed in 3 to 6 weeks.
Concrete pools require extensive on-site labor to form and pour the structure, which takes time to cure properly before finishing touches can be applied. Depending on the complexity of the design and weather conditions, installation can take 3 to 6 months or longer. This longer timeline means a greater disruption to the yard and home environment, making fiberglass pools a more convenient option for those eager to enjoy their pool sooner.
Will a fiberglass pool look as high-end as a concrete pool in my backyard?
Many modern fiberglass pools are designed to mimic the luxurious aesthetics of custom concrete pools, offering sleek lines, attractive finishes, and contemporary features like integrated spas and tanning ledges. While earlier models were known for more basic designs, today’s fiberglass pools are available in a wide variety of styles that can complement both traditional and modern homes. The perception of quality has improved significantly, and many homeowners find that fiberglass pools look just as upscale as their concrete counterparts.
However, some buyers still prefer the unique architectural detailing and natural finish of concrete pools, which can be tailored to the exact specifications of the landscape. For those looking to make a bold visual statement or integrate intricate design elements like rock formations or custom tile work, concrete may offer more flexibility. Overall, the aesthetic gap between the two has narrowed, and fiberglass pools are increasingly regarded as visually appealing and high-end, especially when paired with quality decking, lighting, and landscaping.
