Concrete (Gunite) Pools: Custom, but Costly
Concrete (often called gunite) pools are frequently marketed as the most “customizable” inground option. And it’s true — they can be built in almost any shape or depth. However, that flexibility comes with important trade-offs in timeline, maintenance, and lifetime cost.
Unlike fiberglass pools that arrive as a factory-finished shell, gunite pools are built on-site through multiple construction phases. That process can deliver a highly customized look, but it also increases the chances of delays, weather impacts, and long-term surface upkeep.
Key Characteristics
- Built on-site using steel rebar and sprayed concrete
- Long construction timelines (often 3–6 months or longer depending on scope and weather)
- Porous surface that can encourage algae growth and increases chemical demand
- Typically requires resurfacing every 10–15 years (varies by finish and water chemistry)
Pros
- Nearly unlimited shape and depth customization
- Can accommodate complex designs, edges, and integrated features
- High-end aesthetic potential when new or freshly resurfaced
Cons
- Highest upfront and long-term ownership cost
- Rougher surfaces can be abrasive on skin and swimwear
- Higher chemical use and brushing requirements due to porosity
- Ongoing repairs may include cracks, plaster, tile, and coping maintenance
Best for: Homeowners prioritizing total design freedom and willing to accept higher costs and more maintenance over the life of the pool.
Vinyl Liner Pools: Lower Entry Cost, Ongoing Replacements
Vinyl liner pools are often selected because they typically have a lower upfront price than other inground pool types. But many homeowners don’t fully account for the long-term reality: the liner is a wear item, and replacement is a normal part of ownership.
While vinyl can feel smooth and comfortable, liners are vulnerable to tears, fading, and punctures. Over time, recurring liner replacements can narrow the cost gap versus other options—especially if you plan to stay in your home for the long haul.
Key Characteristics
- Built with steel, polymer, or concrete wall systems
- A vinyl liner is stretched to form the interior surface
- Liners typically need replacement every 7–12 years (varies by use, sun exposure, and chemistry)
- Susceptible to punctures from pets, sharp debris, toys, and improper cleaning tools
Pros
- Lower initial investment compared to most inground options
- Smooth surface feel for swimmers
- Faster build timeline than many concrete (gunite) projects
Cons
- Recurring liner replacement cost every 7–12 years (typical)
- Greater risk of tears, wrinkles, and fading over time
- Fewer step/bench design options than many fiberglass pool models
- May contribute less to long-term resale value than other pool types
Best for: Homeowners prioritizing lower upfront cost who understand that liner replacement is an expected ownership expense over time.
Fiberglass Pools: The Modern Standard for Smart Homeowners
Fiberglass pools have become the fastest-growing segment of the inground pool market—and for good reason. Unlike pools built entirely on-site, fiberglass pools are manufactured in a controlled facility and delivered as a single, fully engineered shell.
This manufacturing process results in a pool that is structurally consistent, factory-finished, and designed for decades of use. Homeowners benefit from faster installation timelines, dramatically lower maintenance, and predictable long-term performance across a wide range of climates and soil conditions.
Key Characteristics
- One-piece factory-built shell engineered for strength and longevity
- Installed in weeks instead of months once site prep is complete
- Smooth, non-porous gelcoat surface that resists algae and staining
- Designed for long-term use with minimal structural maintenance
Advantages
- Lowest lifetime ownership cost among inground pool types
- Minimal chemical usage due to non-porous surface
- Excellent resistance to algae growth and surface staining
- Fast installation reduces backyard disruption
- Comfortable, slip-resistant surface for all ages
- Ideal for saltwater pool systems
Considerations
- Shell shapes and sizes are pre-engineered rather than fully custom
- Requires proper site preparation and experienced installation
- Access is needed to deliver the pool shell to the backyard
At Rainforest Pools, our fiberglass pools are American-made and engineered to perform in challenging environments—including high water tables, variable soil conditions, and freeze-thaw climates. This makes fiberglass an ideal solution for homeowners across the Southeast, Mid-Atlantic, and expanding national markets.
Best for: Homeowners who want the best balance of durability, beauty, speed of installation, and long-term value with minimal maintenance.
Cost Comparison: Fiberglass vs Concrete vs Vinyl Pools Over Time
When comparing pool types, it’s easy to focus only on the upfront number. But the true cost of ownership includes maintenance, repairs, and surface replacements over time. Below is a practical way to think about real-world costs for fiberglass, concrete (gunite), and vinyl liner pools.
Typical Initial Installation (Ranges)
- Fiberglass Pools: $55,000 – $155,000
- Concrete (Gunite) Pools: $80,000 – $200,000+
- Vinyl Liner Pools: $45,000 – $85,000
These ranges vary based on size, access, excavation needs, decking, and upgrades.
30-Year Ownership Reality
- Concrete pools often cost 2–3× more than fiberglass over time due to resurfacing, higher chemical demand, and ongoing repairs.
- Vinyl pools typically require multiple liner replacements, which can narrow the gap versus other options if you own the pool long-term.
- Fiberglass pools generally maintain the lowest lifetime cost thanks to their durable, non-porous surface and reduced maintenance burden.
Bottom line: If you’re planning to stay in your home for many years, the lowest sticker price doesn’t always mean the lowest lifetime cost. Comparing ownership costs—not just installation—helps you choose the pool type that fits your goals and budget.
Maintenance Differences Between Fiberglass, Concrete & Vinyl Pools
Ongoing maintenance and water chemistry play a major role in the true cost and enjoyment of pool ownership. The surface material of your pool directly affects chemical demand, cleaning frequency, and how easily algae can take hold.
| Maintenance Factor | Fiberglass Pools | Concrete (Gunite) Pools | Vinyl Liner Pools |
|---|---|---|---|
| Chemical Demand | Low | High | Moderate |
| Brushing Required | Rare | Weekly | Occasional |
| Algae Growth Risk | Minimal (non-porous surface) | Frequent (porous surface) | Moderate |
| Surface Staining | Resists staining | Common over time | Possible with age |
| Saltwater Compatibility | Excellent | Poor | Good |
Why this matters: Pools that require less brushing and fewer chemicals are not only easier to own, but also more predictable in monthly operating costs—especially in warm climates where algae growth is more aggressive.
Which Pool Type Adds the Most Home Value?
Beyond personal enjoyment, many homeowners consider how an inground pool may impact resale value and buyer appeal. While all pools can enhance lifestyle and curb appeal, not all pool types are viewed equally by future buyers.
Fiberglass Pools
Fiberglass pools consistently rank highest for resale appeal thanks to their low maintenance requirements, smooth surfaces, and modern design options. Buyers are often attracted to the idea of owning a pool without the burden of intensive upkeep.
- Strong buyer appeal due to ease of ownership

- Typically ages well with minimal visible wear
Concrete (Gunite) Pools
Concrete pools can add value, particularly in high-end custom homes, but they may also raise concerns for buyers familiar with the ongoing maintenance and resurfacing costs. Older concrete pools can sometimes become negotiation points during resale.
- High-end appearance when new or recently resurfaced
- Potential buyer hesitation due to maintenance expectations
- Condition at time of sale plays a major role
Vinyl Liner Pools
Vinyl liner pools generally contribute the least to long-term resale value. Buyers often factor in the cost and timing of liner replacement, which can reduce perceived value at the time of sale.
- Lower buyer confidence in long-term durability
- Liner age and condition heavily influence resale impact
- Often viewed as a short- to mid-term solution
Key takeaway: Fiberglass pools tend to deliver the strongest balance of enjoyment, durability, and resale appeal—making them a popular choice for homeowners thinking long-term.
