This article will guide you through the primary types of inground pools—concrete (gunite), fiberglass, and vinyl liner—breaking down their benefits, drawbacks, costs, and ideal use cases to help you make an informed, confident choice that’s perfect for your backyard lifestyle.
Understanding the Main Types of Inground Pools
Before diving into the pros and cons of each type, it’s crucial to understand what makes each type of inground pool unique. The primary options available are:
- Concrete (gunite or shotcrete) pools
- Fiberglass pools
- Vinyl liner pools
Each offers a distinct blend of durability, customization, cost, and maintenance. Choosing the best type of inground pool for you depends heavily on your budget, personal preferences, and how much work you’re willing to put into pool maintenance.
1. Concrete (Gunite or Shotcrete) Pools
Concrete inground pools, often referred to as gunite or shotcrete pools, are the most popular and durable options for custom designs.
Construction Process
Concrete pools are formed by spraying a mixture of cement and sand (gunite) or wet concrete (shotcrete) onto a rebar framework. Once it hardens, the structure is finished with plaster, tile, aggregate, or other surfacing materials.
Advantages of Concrete Pools
- Premium Customization: These pools can be built in nearly any shape, size, and style, allowing unmatched creativity.
- Durability: Built to last over 50 years, with the proper maintenance.
- Resale Value: Concrete pools tend to boost the resale value of a home more than other types.
- Surface Upgrades: The interior finish can be repaired or updated over time to suit aesthetics or needs.
Disadvantages of Concrete Pools
- Higher Cost: They are typically the most expensive upfront, often ranging from $50,000 to $100,000 or more.
- Maintenance: Because they offer porous interiors (especially with plaster), they need more intensive chemical balancing and regular resurfacing every 7–12 years.
- Longer Installation Time: Installing a concrete pool can take several months, depending on the design and weather conditions.
Who Are Concrete Pools Best For?
Concrete pools are ideal for homeowners seeking a completely customized backyard oasis with a long-term investment in mind. They suit luxury design elements such as infinity edges, multiple depths, and integrated spas.
2. Fiberglass Inground Pools
Fiberglass pools have grown increasingly popular over the past decade, especially among homeowners prioritizing low maintenance and relatively quick installation.
Construction Process
Fiberglass pools are pre-manufactured by fabricating a one-piece unit composed of layers of fiberglass-reinforced polymer. These units are then delivered to the site and installed inside a dug-out excavation.
Advantages of Fiberglass Pools
- Much Lower Maintenance: Smooth, non-porous surfaces resist algae growth and limit chemical demands.
- Quick Installation: Can often be completed within 3 to 6 weeks from start to finish.
- Cost-Effective Long-Term: Though initial costs hover around $40,000–$80,000, their lower upkeep saves money over time.
- Longer Lifespan than Vinyl: Fiberglass shells can typically last 25+ years with minimal degradation.
Disadvantages of Fiberglass Pools
- Limited Design Options: Shapes and sizes are predesigned, offering less flexibility for customization.
- Transportation Costs: Larger pools may incur additional fees for shipping, especially in remote areas.
- Cracking and Repairs: While rare, structural movement or poor installation can lead to cracks that are difficult to repair.
- Initial Shading Sensitivity: The glossy finish can accentuate water ripples, and the color of the pool bottom can affect how sunlight is reflected.
Who Are Fiberglass Pools Best For?
Fiberglass pools are best for homeowners who want a long-term low-maintenance pool with a quick installation time and clean design that fits common aesthetic preferences. They’re also great for families seeking a hassle-free entry into pool ownership.
3. Vinyl Liner Inground Pools
Vinyl liner pools are another popular choice due to their affordability and relatively straightforward installation.
Construction Process
The structure is built using aluminum, steel, or polymer wall systems surrounding a hole filled with sand or a cradled base. Once the structure is in place, a customized vinyl liner is fitted inside to hold the water.
Advantages of Vinyl Liner Pools
- Affordable: Often the most cost-effective, with average installation ranging from $35,000 to $65,000.
- Flexible Design: Unlike fiberglass, vinyl pools can be shaped almost anyway, including steps, ledges, and benches made from the steel or polymer structure.
- Easier to Repair: Damages to the liner can be repaired with patches; full liner replacement is affordable compared to concrete resurfacing.
Disadvantages of Vinyl Liner Pools
- Shorter Lifespan: Vinyl liners typically require replacement every 5–9 years, depending on usage and care.
- Prone to Tears: Sharp objects or poor installation can puncture the liner.
- Less Durable Finish: Though the structure is strong, the vinyl lining isn’t as resilient as concrete or fiberglass interiors.
- Higher Chemical Needs: Liners sometimes lead to uneven chemical mixes, especially if not well-maintained.
Who Are Vinyl Liner Pools Best For?
Vinyl liner pools work well for budget-conscious buyers looking for a more flexible design and are prepared for scheduled liner replacement every several years.

Other Considerations When Choosing the Best Inground Pool
Climate and Weather Conditions
Depending on where you live, the local climate can impact the best pool type for your yard.
- In colder climates, fiberglass pools may experience fewer freeze/thaw issues due to the flexible shell, while vinyl pools have a higher risk of liner shrinkage or expansion.
- In consistently sunny areas, concrete pools are more durable in high UV environments but may require more water and chemical maintenance due to higher evaporation rates.
- Areas with poor soil drainage or frequent flooding might benefit from fiberglass due to the quicker installation and non-porous bottom.
Soil Conditions and Yard Grading
Before you begin pool construction, a professional must evaluate the ground quality and water table level.
- Fiberglass can be vulnerable to shifting or buoyancy if installed in areas with a high water table.
- A concrete pool provides better weight distribution and resistance to such issues if reinforced properly.
- Vinyl liner pools are also at risk if the water table is high unless there is an adequate hydrostatic relief system in place.
Aesthetic Preferences and Personal Style
Visual appeal is an important consideration.
- Do you enjoy bold design features? Go with concrete.
- Prefer clean lines and modern elegance? Fiberglass is a sleek solution.
- Desire an affordable option that still looks good? Vinyl liner, with the help of a skilled builder, can also look fantastic.
Which Type of Inground Pool Yields the Highest Return on Investment?
Real estate experts and pool contractors alike debate this question constantly, but data shows that a well-constructed pool consistently provides added value. That said, not all types deliver equally.
Concrete Pools: Highest Resale Value
Concrete pools add the most property value because of their durability, permanency, and attractive designs. According to Zillow, a pool can add about 8% of the home’s value, especially in the right markets, such as in California, Florida, and Texas.
Fiberglass and Vinyl Liners
Fiberglass and vinyl options can increase property value, but they have less of an ROI than concrete because they are not considered as permanent by potential buyers. However, when well-maintained and stylish, both types still offer a return—particularly in more modest home markets.
Bottom Line
If investment return is your primary concern, concrete is the most favorable choice. That said, other types can still perform well in certain housing markets and lifestyles.

What are the main types of inground pools available?
There are three primary types of inground pools: vinyl liner, concrete (gunite), and fiberglass. Each has its own set of benefits and potential drawbacks. Vinyl liner pools are generally the most affordable and offer a smooth surface and flexibility in design. Concrete pools provide the greatest customization in size, shape, and finish, but require more maintenance and have longer installation times. Fiberglass pools are pre-manufactured shells that are installed in the ground, known for their durability and low maintenance requirements.
The choice largely depends on budget, personal preferences, and long-term maintenance willingness. While vinyl liners need to be replaced every 5 to 9 years, concrete pools may require resurfacing every 10 years or so. Fiberglass pools, though less customizable, tend to retain their finish for decades with minimal care. Understanding these distinctions is key to determining which type fits your lifestyle and landscape needs the best.
How much does each type of inground pool cost?
Cost is one of the most influential factors when choosing an inground pool. On average, vinyl liner pools are the least expensive, typically ranging from $35,000 to $65,000. Concrete pools are on the higher end, often starting at $50,000 and easily exceeding $100,000 depending on size and custom features like waterfalls, spas, or tanning ledges. Fiberglass pools fall somewhere in the middle, generally costing between $45,000 and $85,000, including installation and basic features.
These prices can be affected by site preparation, location, local labor rates, and added extras such as decking, fencing, and heating systems. Vinyl may offer lower initial costs, but ongoing replacements of the liner add to the lifetime expense. Concrete pools tend to have the highest starting cost and ongoing maintenance, while fiberglass, though moderately priced, often includes more features out of the box. Budgeting for both installation and long-term operating costs is crucial when deciding on a pool type.
Which inground pool is the easiest to maintain?
Fiberglass pools are widely regarded as the easiest to maintain due to their non-porous surface, which resists algae growth and requires fewer chemicals and less cleaning. They also don’t need resurfacing like concrete pools or liner replacements like vinyl pools. Maintenance typically includes regular water testing, filter cleaning, and occasional vacuuming. The smooth finish also makes them comfortable for swimmers and less abrasive on swimwear and skin.
Concrete pools, by contrast, require more diligent care due to their tendency to harbor algae and mineral buildup. They also require surface acid washing or resurfacing every 10 to 15 years. Vinyl liner pools, while easier than concrete in some respects, demand careful monitoring of chemical balance to extend the life of the liner and prevent punctures. Between the three, fiberglass provides the best mix of durability and low maintenance, making it ideal for homeowners who want a straightforward pool-ownership experience.
Can inground pools be customized in shape and design?
Concrete (gunite) pools offer the highest level of customization in terms of shape, size, and design features. Since the structure is built on-site using sprayed concrete, nearly any vision can be realized, from freeform lagoons to geometric lap pools. This makes them the preferred choice for homeowners who want a unique, tailored backyard oasis complete with custom spillways, vanishing edges, and integrated spas or water features.
Vinyl liner pools also offer some degree of customization through different panel designs and pre-constructed pool walls, but they are limited compared to concrete options. Fiberglass pools come in pre-molded shapes and sizes, which means customization is more limited in terms of layout and features. However, many fiberglass models are designed with modern aesthetics and functional elements such as tanning shelves and built-in seating. For total design freedom, concrete is the top choice.
How long does each type of inground pool last?
The lifespan of an inground pool varies by type and maintenance. Fiberglass pools are among the most durable, lasting 25 to 30 years or more with proper care. Their shells are resistant to cracking and fading in well-maintained environments. Concrete pools can last even longer—often 50 years or more—if properly maintained, though their surfaces may require resurfacing every 10 to 15 years. Vinyl liner pools typically last 15 to 20 years, with the liner itself needing replacement every 5 to 9 years depending on usage and condition.
These lifespans can be affected by local climate, water chemistry, and how well the pool is winterized in colder regions. Concrete pools are more susceptible to structural issues if not installed correctly or if seismic activity occurs. Fiberglass pools hold up well in varying climates and resist shifting due to their flexibility. Vinyl liners, while cost-effective initially, are more vulnerable to UV damage, punctures, and wear over time. Planning for long-term use and maintenance is important for maximizing your pool’s longevity.
Which type of pool offers the best resale value?
Concrete pools are often considered to offer the best resale value due to their durability and the perception of luxury they convey. High-end installations with unique designs and premium finishes can significantly increase curb appeal and attract potential buyers who are looking for a custom-built pool. However, the maintenance demands and potential need for resurfacing can be a drawback for some buyers.
Fiberglass pools, while offering excellent long-term savings and ease of ownership, may not impress buyers who prefer concrete’s customizable appeal. Still, they hold their value well, especially when installed with quality craftsmanship and modern features. Vinyl liner pools, being the most cost-effective initially, often have less impact on resale value, partly because of concerns about liner wear and upcoming replacement costs. Ultimately, the best resale value depends on the local market and buyer preferences, but concrete and fiberglass are seen as better long-term investments.
What factors should I consider before choosing an inground pool type?
When deciding on an inground pool, several key factors should be taken into account: budget, customization desires, maintenance preferences, and long-term value. The initial investment can vary widely, and it’s important to account for not just installation but also lifetime expenses such as chemicals, repairs, and energy for heating or pumping. If you envision a completely unique design, concrete is likely the best option, while fiberglass and vinyl suit those wanting more straightforward, functional designs.
The climate and geography of your location also play a role—fiberglass pools are great for areas with fluctuating temperatures due to their resilience, while concrete pools may crack in areas prone to ground movement. You’ll also want to factor in how often you’re willing to perform maintenance, and whether you prefer professional help or DIY care. Lastly, consider the impact on your daily life and backyard layout, including space availability and how you intend to use the pool. Taking all these into account ensures you make the best choice for your home and lifestyle.
