Fiberglass vs Vinyl vs Concrete Pool Comparison Guide: Why San Juan Fiberglass Pools Stand Out
Fiberglass Pools: Pre-Manufactured Excellence
Fiberglass pools are made in a factory and delivered to your home as a one-piece shell. This makes them quick to install and highly dependable. But not all fiberglass pools are built the same—and that’s where San Juan Pools sets itself apart.
At San Juan Pools, we believe in one simple truth: Build the highest-quality fiberglass swimming pools and spas—every time.
For us, this is more than just a slogan. It’s a commitment. It guides every step we take, from material selection to final finishing. We’ve spent decades perfecting our process to ensure each pool we build meets the highest standards in strength, safety, and beauty.
Unlike many fiberglass pool manufacturers, we use 100% hand-laid fiberglass sheets—no shortcuts, no fillers, no compromises. This process is slower and more labor-intensive, but it delivers a far stronger, more durable result. In fact, we go even further by using a powerful blend of:
Hand-Laid Fiberglass Sheets – Each layer is placed with precision and care
Woven Roving Reinforcement – Adds structural strength and impact resistance
Vinyl Ester Resin – Provides top-tier resistance to corrosion, blistering, and water damage
The result? The strongest fiberglass pool shell on the market.
Why choose a fiberglass pool from San Juan Pools?
Fast installation – Most pools are swim-ready in 2–6 weeks
Superior strength – Built to withstand time, weather, and use
Low maintenance – The smooth surface resists algae and reduces chemical use
Beautiful finishes – Choose from a wide range of colors and styles
Proven longevity – Our pools can last 50+ years with proper care
With over 65 years of experience and innovation behind us, we don’t just build pools—we build peace of mind. When you choose San Juan Pools, you’re choosing a company that stands behind every shell we send out, because we know what goes into it.
Vinyl Liner Pools: Budget-Friendly Option
Vinyl liner pools are built on-site using a frame and a flexible liner. The liner is stretched over the shape of the pool and sealed into place.
This type of pool is often chosen for its lower upfront cost. But there are trade-offs to consider.
Pros of vinyl liner pools:
Lower starting price – A good option if your budget is tight.
Soft liner surface – Gentle on feet and skin.
Customizable shapes – Some flexibility in design.
Cons to keep in mind:
Liner replacements – Most liners need to be replaced every 7 to 10 years.
Risk of damage – Liners can tear or wrinkle from sharp objects or pool toys.
More maintenance – Water chemistry must be watched carefully to protect the liner.
Lower resale value – Some home buyers see vinyl pools as temporary or less durable.
We often hear from homeowners who started with vinyl and later switched to fiberglass because they wanted something stronger, easier to care for, and built to last.
Concrete Pools: Traditional Custom Choice
Concrete pools (also called gunite or shotcrete pools) are built by spraying concrete over a rebar frame. This allows for full customization of size, shape, and depth.
If you have a very specific design in mind, concrete gives you nearly unlimited options. But the custom process takes time—and comes with added cost and upkeep.
Benefits of concrete pools:
Fully custom shapes – Great for unique backyards or luxury builds.
Deep end options – Easier to build extra-deep sections.
High-end finishes – Tile, pebble, and other surfaces available.
Drawbacks to consider:
Long install time – It can take 3–6 months to finish.
Higher costs – Both upfront and over the pool’s life.
Frequent maintenance – Algae loves concrete’s porous surface.
Resurfacing required – Usually needed every 10 to 15 years.
Rough texture – Can be hard on feet and skin.
We respect the tradition of concrete pools, but for most families, the time, cost, and care required make them less practical. That’s why we focus on fiberglass—offering you a smoother experience in every way.
Initial Installation: Time, Process, and Complexity
Installing a pool is a big project, but the process can look very different depending on the type of pool you choose. Time, weather, materials, and complexity all play a role.
At San Juan Pools, we’ve seen firsthand how the right pool choice can make installation faster and smoother—not just for us, but for you and your family too. Here’s how each type of pool compares when it comes to getting it in the ground and swim-ready.
Fiberglass Pool Installation Timeline
When it comes to speed and simplicity, fiberglass pools—especially those from San Juan Pools—are hard to beat. Because each pool shell is pre-manufactured in our factory, there’s no need to build it from scratch on your property.
With the help of certified San Juan Dealers, installation becomes fast, professional, and hassle-free.
Here’s how the installation process typically works with San Juan Dealers:
Site Prep & Digging – The dealer prepares your yard and excavates the space based on the selected model.
Delivery & Placement – Your San Juan fiberglass shell arrives in one piece and is gently set into the ground using cranes and precise leveling.
Plumbing & Backfill – Plumbing is installed, electrical connections are made, and gravel or sand is used to backfill the space around the pool shell.
Decking & Finish Work – Concrete decking is poured, landscaping is completed, and final features are added.
Most San Juan Fiberglass Pools are fully installed and swim-ready in just 2 to 6 weeks, depending on weather conditions and site accessibility.
Why fiberglass is faster:
No delays waiting for concrete to cure
No liner to stretch or install
Less yard disruption and mess
Factory-controlled quality = fewer on-site problems
In many cases, families are swimming within days of pool delivery. That’s the kind of speed and quality that comes with working with San Juan Pools and our trusted dealer network.
Vinyl Liner Pool Installation Process
Vinyl liner pools take a little more time and involve more steps on-site. These pools are built in your backyard from the ground up, using panels or walls to create the shape before adding the liner.
Typical vinyl pool installation steps:
Excavation – The hole is dug to fit your planned pool shape.
Wall Construction – Metal or polymer wall panels are bolted into place.
Bottom Work – The pool floor is shaped and smoothed, usually with sand or a cement-like mix.
Liner Installation – A custom vinyl liner is placed, stretched, and sealed.
Plumbing & Backfill – Pipes are installed and the structure is supported.
Decking & Finish Work – Final steps include pouring concrete decking or pavers.
This process usually takes 4 to 8 weeks, depending on complexity, liner availability, and weather.
Downsides to consider:
Weather can delay liner placement
Liners may wrinkle or shift during installation
Future liner replacements mean repeating this process again
While vinyl pools can be a good option for tighter budgets, the longer install time and higher maintenance needs often outweigh the upfront savings.
Concrete Pool Construction Duration
Concrete (also known as gunite or shotcrete) pools are the most complex to build. These pools are poured or sprayed into shape using rebar frames and concrete shells. Every part of the process takes time to cure, set, and finish properly.
A typical concrete pool build involves:
Excavation – Digging the shape of the pool
Steel Reinforcement – Installing a strong cage of rebar
Plumbing Rough-In – Laying pipes before concrete is added
Spraying Concrete (Gunite/Shotcrete) – Concrete is sprayed over the steel frame
Curing – Concrete must cure for 28+ days to gain full strength
Tiling & Finishes – Applying plaster, tile, or pebble interior
Decking & Equipment Setup – Pouring the surrounding deck and installing hardware
Because of all the steps, most concrete pool builds take 3 to 6 months, sometimes longer. And that’s assuming good weather and no permit delays.
Why concrete takes the longest:
Multiple specialized crews
Long curing times
More inspections and delays
Highly customized = more complexity
While concrete offers maximum design freedom, the waiting time, noise, and disruption can stretch over an entire season.
Long-Term Maintenance Requirements
Installing a pool is only the beginning. How much work your pool takes to keep clean, safe, and beautiful over the years is just as important as how it looks on day one.
Different pool types require very different levels of care. From daily cleaning to seasonal upkeep and repair costs, long-term maintenance can affect your time, budget, and overall enjoyment.
At San Juan Pools, we believe a great pool should be fun to own—not a chore to manage. Let’s take a closer look at how fiberglass, vinyl liner, and concrete pools compare when it comes to maintenance.
Fiberglass Pool Maintenance Simplicity
One of the biggest reasons people choose fiberglass is how easy it is to care for. San Juan Pools are built with a smooth, non-porous gelcoat surface that naturally resists algae, dirt, and staining.
That means:
Less brushing – No rough surface for algae to grip
Fewer chemicals – pH stays stable, so you use fewer additives
Shorter cleaning time – Debris brushes off easily
Lower filter demand – Water stays clearer with less effort
In many cases, our customers can maintain their San Juan Pool with just a few minutes of care per week. This includes:
Skimming leaves
Checking chlorine and pH levels
Running the pump during warm months
Because our fiberglass shells are so durable, they almost never need resurfacing or structure repairs. Many pool owners go decades without needing major work.
"Simple care, clean water, and long-lasting materials. That’s what we aim for with every pool we build."
Vinyl Liner Replacement and Upkeep
Vinyl liner pools require more regular attention—and eventually, more money. The soft liner material is easier to damage and can’t last forever, even with good care.
Key maintenance points:
Liner replacement every 7–10 years – This can cost $4,000–$6,000, depending on size and labor.
Liner repairs – Sharp toys, pets, or pool vacuums can cause tears or leaks.
Algae growth – Vinyl is smooth, but seams and wrinkles can trap bacteria.
More chemical adjustments – Vinyl liners are sensitive to imbalanced water.
Regular maintenance includes:
Weekly brushing and vacuuming
Monitoring chlorine and alkalinity
Checking for wrinkles or discoloration
Covering the pool to reduce liner damage from the sun
While vinyl may start out as the more affordable option, the ongoing upkeep adds up. Many homeowners end up spending thousands over time just to keep it looking new.
Concrete Pool Resurfacing and Chemical Demands
Concrete pools require the most time and effort to maintain. That’s because concrete is porous, which makes it a perfect place for algae, mold, and mineral buildup.
Even with the best equipment, concrete pools demand:
Frequent brushing – Walls and floors need scrubbing 2–3 times a week.
Heavy chemical use – More acid, chlorine, and shock treatments are needed to keep water balanced.
pH swings – Concrete interacts with water chemistry, which causes regular changes in acidity.
Algae control – Concrete surfaces can stain and harbor algae quickly.
Over time, the surface of a concrete pool wears down. This leads to rough spots, fading, or even cracks.
Expect resurfacing every 10–15 years:
Resurfacing can cost $10,000–$20,000
It involves draining the pool and reapplying plaster, pebble, or tile
Delays or poor weather can drag the process out for weeks
For homeowners who don’t want the hassle, concrete often becomes a regret due to its demanding care and expensive maintenance cycle.
Durability and Lifespan Expectations
When choosing a pool, it’s smart to think long-term. A pool isn’t just a seasonal feature—it’s a permanent part of your home. That’s why it’s important to understand how long each type of pool will last and what kind of wear and tear you can expect over time.
At San Juan Pools, we focus on building pools that stand the test of time. Durability isn’t just a promise—it’s built into every pool we deliver.
Let’s look at how fiberglass, vinyl liner, and concrete pools compare when it comes to strength and lifespan.
Fiberglass Pool Longevity
Fiberglass pools are known for being incredibly strong. At San Juan Pools, we take that a step further by using 100% hand-laid fiberglass sheets, woven roving, and vinyl ester resin in every pool shell. This unique combination helps prevent cracking, blistering, or weakening—even after decades of use.
Here’s why fiberglass lasts so long:
Non-porous shell – Resists water damage, algae, and chemical wear
Flexible strength – Fiberglass can handle ground shifts and pressure changes
No resurfacing needed – Gelcoat finish stays smooth for decades
Low chemical impact – Less wear from harsh pool treatments
With proper care, a San Juan Fiberglass Pool can easily last 50 years or more. In fact, many of our early models from the 1960s are still in use today—proof of what true craftsmanship looks like.
"If u want a beautiful and durable pool, please check out the beautiful selection built by a quality company, San Juan Pools. Our San Juan Fiberglass Pool is 42 yrs old and still looks and functions very well we have never had a problem with tiles coming off and it was shipped to us with them already attached." - Lana Forster
Vinyl Liner Replacement Frequency
Vinyl liner pools have a much shorter lifespan, mostly due to the liner itself. While the pool structure may last longer, the liner must be replaced every 7 to 10 years, even with excellent care.
What causes liner breakdown?
Sun exposure – UV rays weaken the material over time
Chemical erosion – High chlorine levels can dry and crack the liner
Tears and punctures – Sharp toys, pets, or pool equipment can cause damage
Wrinkles and shrinkage – Liners shift or stretch with changes in water temperature and ground movement
Replacing a liner isn’t just inconvenient—it’s also expensive. A full replacement can cost $4,000–$6,000 or more, depending on your pool’s size.
Some pool owners find themselves replacing the liner multiple times over 20 years, which adds up in both cost and hassle.
Concrete Pool Aging Process
Concrete pools are strong, but their surface is their weak point. Over time, the plaster, tile, or pebble finish begins to wear down. This leads to staining, rough patches, and eventually, cracks or leaks.
Common issues as concrete pools age:
Surface erosion – Water and chemicals slowly break down plaster or tile
Cracks – Ground shifts and freeze/thaw cycles cause hairline cracks
Rebar rusting – Metal inside the concrete can rust and cause stains or bulging
Higher porosity – As concrete ages, it becomes more porous and harder to clean
Most concrete pools need resurfacing every 10 to 15 years, which usually costs between $10,000 and $20,000. If structural cracks appear, repairs can be even more costly—and disruptive.
While concrete can last for decades with proper care, it comes with more effort and expense than fiberglass.
Aesthetic Options and Design Flexibility
Your pool should do more than just cool you off. It should also fit your style, enhance your outdoor space, and reflect your personal taste.
While all three pool types—fiberglass, vinyl liner, and concrete—offer visual options, they differ in how much design freedom you actually have. At San Juan Pools, we believe beauty shouldn’t come with stress. That’s why our fiberglass models are made to be both elegant and easy to install.
Let’s explore how each pool type compares in terms of shape, color, and overall customization.
Fiberglass Pool Shapes and Finishes
Fiberglass pools may not be custom-built from scratch, but that doesn’t mean they lack variety. In fact, San Juan Pools offers over 100 pre-designed models, giving you a wide selection of shapes, sizes, and features—all crafted with precision and style.
Our fiberglass pool options include:
Modern rectangles – Perfect for sleek, clean backyard designs
Freeform curves – Ideal for a natural or tropical look
Roman ends or kidney shapes – Classic style that never goes out of fashion
Built-in features – Beach-entry, tanning ledges, and swim-out bench
Every San Juan Fiberglass Pool is finished with a high-gloss gelcoat that comes in a range of stunning colors, from blue lagoon to granite. These finishes don’t just look good—they’re also UV-resistant, smooth to the touch, and easy to maintain.
Because our pools are built in factory molds, each design has been tested and refined for beauty, balance, and performance. You get a polished, designer look without the risk of trial-and-error construction.
Vinyl Liner Pattern Choices
Vinyl liner pools offer moderate flexibility in terms of appearance. You can choose from a variety of liner patterns and colors, which help personalize your pool’s look.
Common vinyl liner design features:
Printed tile borders – Mimic the look of stone or ceramic tile
Blue and gray color tones – Some styles offer textured or marbled effects
Seamless look – When properly installed, liners can create a smooth visual flow
However, there are limitations:
Fixed liner patterns – You’re limited to what manufacturers offer
Color fading – Sun exposure and chemical use can dull the design over time
No structural add-ons – Features like tanning ledges or benches must be built separately, not part of the liner shell
While vinyl liners can look nice initially, the visual appeal can wear down quickly, especially in sunny or high-use environments. If appearance is a long-term priority, fiberglass or concrete will likely give you more value.
Concrete Pool Customization Potential
Concrete pools are known for their unmatched design freedom. Because they’re built entirely on-site, concrete can be poured and shaped into nearly any form imaginable.
With concrete, you can customize:
Any shape or size – From classic to artistic and one-of-a-kind
Depth variation – Easy to add diving zones or beach entries
Material finishes – Choose from plaster, tile, pebble, quartz, or stone
Integrated features – Custom water features, vanishing edges, or swim-up bars
This level of flexibility comes at a cost—both in terms of money and time. Custom concrete pools often take months to complete, and complex features can increase the chance of construction delays or problems.
Additionally, over time, concrete surfaces may lose their beauty without regular resurfacing or repairs. What starts as a showpiece can become a maintenance-heavy project.
At San Juan Pools, we respect what concrete can offer. However, we’ve found that most homeowners prefer the balance of elegance, ease, and efficiency that fiberglass delivers—especially when they see our range of model designs.
Swimming Experience and Feel Differences
A pool should look great, but it should feel great too. After all, your family and friends will be walking, sitting, and swimming in it for years to come.
Different pool materials create different touch sensations, which affect both comfort and safety. From soft finishes to rough edges, the surface feel plays a bigger role than most people realize.
At San Juan Pools, we believe every swim should feel smooth, safe, and relaxing. Let’s explore how fiberglass, vinyl liner, and concrete pools compare when it comes to daily use.
Fiberglass Pool Comfort and Safety
Fiberglass pools are known for their ultra-smooth finish. At San Juan Pools, we take this to the next level with our gelcoat surface, which is designed to be soft on skin and naturally slip-resistant.
Here’s what makes fiberglass so comfortable:
Silky-smooth gelcoat – Gentle on hands, feet, and swimsuits
No sharp edges – Rounded steps and benches for safer entry
Non-abrasive surface – No scrapes or raw skin after long swims
Slip resistance – Especially around steps, ledges, and tanning shelves
Because fiberglass is non-porous, it doesn’t hold onto dirt or algae. This keeps your pool surface cleaner and more hygienic—less slimy build-up means a better swimming experience.
And when it comes to safety, fiberglass offers peace of mind. There are no exposed seams, no sharp tiles, and no abrasive textures. That’s one of the many reasons families choose San Juan Pools for young children, seniors, and anyone who values comfort.
Vinyl Liner Texture and Experience
Vinyl liner pools have a soft, flexible surface, which can feel pleasant underfoot. The texture is generally smooth, and many swimmers enjoy the gentle feel—at least at first.
However, there are a few important factors to consider:
Pros:
Soft texture – Feels nice for lounging or light swimming
Smooth seams – When well-installed, liners can appear almost seamless
Less abrasive – Won’t scratch skin like rougher surfaces can
Cons:
Wrinkles and folds – Over time, liners can shift, causing ridges that feel uncomfortable
Punctures – Sharp objects or rough play can tear or dent the liner
Fading – The surface can become rough or dull with age and sun exposure
Seam sensitivity – Some swimmers feel the liner seams underfoot, especially near steps
Vinyl can be comfortable, but it doesn’t always stay that way. As the liner ages, the material can become brittle, and seams may lift or bubble. For families looking for a longer-lasting, consistently smooth feel, fiberglass offers more reliability.
Concrete Pool Surface Feel
Concrete pools may offer maximum design freedom, but their surface isn’t always swimmer-friendly. These pools are usually finished with plaster, pebble, or tile, all of which can feel rougher than fiberglass or vinyl.
Key surface traits:
Textured finish – Rougher material may scrape feet, knees, and hands
Plaster erosion – Over time, plaster can become sharp or pitted
Higher friction – Increases wear on swimsuits and pool toys
More brushing required – Concrete holds onto algae and dirt
If not maintained regularly, a concrete pool surface can deteriorate, creating a gritty feel and potential safety concerns. While higher-end finishes like pebble can offer a smoother texture, they still don’t match the soft, even feel of a fiberglass pool.
At San Juan Pools, we’ve had many customers switch from concrete to fiberglass because they were tired of rough surfaces and constant resurfacing.
Conclusion: Making the Right Pool Choice for Your Lifestyle
Choosing the right pool isn’t just about materials or price—it’s about finding the best fit for your home, lifestyle, and long-term happiness. Whether you’re building your first backyard oasis or upgrading from a high-maintenance model, the type of pool you choose will shape your experience for years to come.
After walking through the pros and cons of fiberglass, vinyl liner, and concrete pools, one thing becomes clear: not all pools are created equal.
At San Juan Pools, we believe the right pool should:
Be quick and easy to install
Require minimal long-term maintenance
Feel great to swim in, every time
Offer beauty and durability that lasts decades
Bring more joy than stress into your life
