Fiberglass Pools: Pros, Cons, and Other Considerations

Fiberglass Pools: Pros, Cons, and Other Considerations

Fiberglass Pool Information  |  Fiberglass vs Concrete vs Vinyl Liner

Thinking about getting an inground pool for your backyard? You've probably been doing quite a bit of research on your options. Right now, you might be trying to narrow your options down to a fiberglass pool... or something else. By the end of this article, you should have a much better understanding of whether or not fiberglass is the best choice for your pool project, as well as the pros and cons of having a pool.


Nothing in life is perfect. Inground pools of any type certainly aren’t, either. We exclusively manufacture and install fiberglass swimming pools at River Pools, but we've been in this business long enough to understand that fiberglass isn't the best fit for every backyard.


We want all pool buyers to make the best choice for their lives and homes. Over the years, we've turned away hundreds of potential customers if they’re clearly looking for something (a certain size, a specific shape, a distinct set of features, or anything else) better suited to a concrete or vinyl liner swimming pool.

At the end of the day, we want families to enjoy time together around their pool -- whether or not they choose to work with River Pools. We believe everyone deserves the swimming pool of their dreams, whether it's made of fiberglass, concrete, or a vinyl liner.


Today, we’ll go over pros and cons of owning a pool whether it’s a vinyl liner, concrete or fiberglass pool. We’ll make our case for fiberglass pools, but you'll also get an honest assessment of the common disadvantages to fiberglass pools. Consider both sides, but always do your own research and consider your sources before making your final choice. This can help you decide “is owning a pool worth it?” Your pool should last as long as you own your home, so you should love whatever pool you get!


Pros and cons of owning a pool



  • A Fun Way to Exercise

What are the advantages of swimming, you might ask? There are many physical and mental benefits of swimming, and swimming pools are a great way to stay fit and work out numerous parts of your body. 

  • A Beautiful Edition to Your Backyard Space

They’re often considered a luxury item for a reason - inground pools add a sense of elegance and beauty to any home and backyard they have found themselves in.  

  • Can Increase Your Home’s Value

Does a pool help or hurt home value? It depends - a lot on where you live and how desirable a pool is in your area. Oftentimes, a well-maintained inground pool can add value to one’s home. We’ll discuss this a bit more later.



  • Expenses Will Go Into Installation and Maintenance

You know what they say, nothing in life is free. Unfortunately, getting your own pool is going to cost you, and how much you pay for installation and maintenance will depend on what type of inground pool you choose. But fear not! We have a guide to give you the have-to-knows for the different inground pools available. You can get your hands on it here.

  • Will Require Time and Effort Throughout the Pool’s Lifetime

Oftentimes, people will ask “Is owning a pool a lot of work?” And we always say: well, it depends. One reason we are passionate about fiberglass is that they are the lowest maintenance inground pool type out there (we’ll get into more detail later)


There are plenty of reasons to get an inground pool that’s all your own, and there’s also reasons why not to get a pool. It’s important to assess these and determine 100% is having a pool in your backyard worth it before moving forward with a decision. This will help prevent you from going through swimming pool buyers remorse. But as we said, our expertise lies with inground fiberglass pools, so we would like to spend our time with you focusing on fiberglass.


The benefits (pros) of fiberglass pools

Let's be up front before we get started: all fiberglass pools are NOT created equal. The advantages we'll cover here apply to high-quality, well-manufactured fiberglass swimming pools.


Virtually everything in this guide has been covered in great detail throughout our comprehensive fiberglass pool buyer's guide. We highly recommend getting a copy (it's a free eBook you can download and read anywhere) so you'll have everything you might need or want on your pool-buying journey in one handy place.

Fiberglass pools are durable

One main advantage of fiberglass swimming pools is their high durability -- inside and out.


Both the structure and the surface of a high-quality fiberglass pool can last a long time, provided you take good care of it.


A well-made fiberglass pool can last at least 50 years, with less maintenance required to keep it useful and enjoyable decade after decade. Speaking of maintenance...


Fiberglass pools are low maintenance

Fiberglass swimming pools really are as low-maintenance as you've heard.


For example, the non-porous surface (the gelcoat) of a fiberglass pool resists algae growth and won't react with the chemicals commonly used to sanitize pool water. This simply means you won’t have to spend as much time adding and balancing chemicals or scrubbing the walls.


You won’t have to worry about acid washing or patching holes in your fiberglass pool's surface as you might with other pools.


Fiberglass pools require less ongoing labor

Continuing from our last section, you’ll spend a lot less time and energy keeping your fiberglass pool in good shape.


Fiberglass pools don’t need to be acid washed, won't develop any wrinkles you'll need to smooth out, and they're also free from many of the other common maintenance chores you might need to tackle with other inground pool types.


If you hate pool chores, you might want to explore fiberglass pool maintenance in more detail to see what you’ll actually need to do.


You can always hire a professional cleaning service -- and it might cost less simply because your pool cleaning pro won't have as much work to do each week.


Fiberglass pools have a smooth surface

That non-porous surface --the gelcoat -- is quite smooth, but it's still slip-resistant.


Remember scraping your knees and toes when you were a kid hanging out at your neighborhood's public pool? You don’t have to worry about that with a fiberglass pool.


If you've ever gotten into the shallow end of a pool and scraped your foot on a rough surface, the gelcoat surface of a fiberglass pool could be perfect for you.


Fiberglass pools rarely need resurfacing

While we're on the subject of pool surfaces, a fiberglass pool’s gelcoat can last its entire lifetime without needing replacement or resurfacing.


This isn't true of every fiberglass pool in every backyard, of course.


Some people may find they'll need to resurface their fiberglass pool -- but this is often after years of enjoyable pool ownership.


Compare this to vinyl liners, which need to be replaced about every 5-9 years on average, and concrete pools, which may need complete resurfacing done every 10 years or so.


If your fiberglass pool is well-maintained, you may never need to resurface it.


However, if you ever find yourself needing to replace your fiberglass pool's surface, it can be done with a product like ecoFINISH -- a durable polyethylene powder coating with a wide range of colors and multiple textures. (Read our ecoFINISH review here.)


Fiberglass pools are algae-resistant

Algae is ugly. What's worse is that it forces you to use more chemicals to get rid of it. and algae often forces you to run your pump and filter more often as well.


A fiberglass pool's non-porous surface helps prevent algae from sticking to its walls, which makes algae much less likely to become a problem in your pool -- provided you maintain it regularly!


Other inground pool types may allow for more algae growth due to porosity of the surface. That’s why you have to scrub your pool surface with a steel brush regularly.


Fiberglass pools have lower lifetime costs

All that acid washing, resurfacing, repairing, and liner replacing costs money over the life of your pool ownership.


Because a fiberglass pool doesn't need this sort of work, and because your ongoing maintenance costs will be lower overall, you can often save thousands of dollars over the years over what you might have spent to upkeep other inground pool types.

Fiberglass pools have faster installation times

Want your concrete pool fully built, in the ground, and full of water in two days?


It ain't happening. Unfortunately for concrete (gunite) pool fanatics, concrete pools are built from scratch, with long periods of time for the concrete to cure, thus leading to longer installation times.


However, putting in a pool of the fiberglass variety tends to yield faster installations. The fiberglass pool shell -- which is basically the entire structure you'll swim and lounge in once it's in the ground -- arrives at your home completely manufactured and ready to be installed.


Once it’s in the ground and we begin backfilling the pool, we must also fill the pool with water to equalize the pressure on both sides of the shell. This mandatory backfill-and-fill process results in a much faster installation process overall.


In most cases, your pool project should be wrapped up, with patio installation and everything else you've asked for beyond the pool itself, within just two to six weeks on average.


On average, concrete pools typically take three to six months for full installation.


Vinyl liner pools often take six to eight weeks on average.


Of course, your pool builder will need to be available before your pool can be installed, no matter which type of pool you get. The last two years have seen significant disruptions to both the supply of materials needed to build and install pools (it's much tighter) and the demand for new pool installations (it's much higher), which has resulted in longer wait times for new pools across the country and around the world.

Fiberglass pools are compatible with salt water systems

You might think, "salt water systems can work with any swimming pool."


But just because you can do something doesn't mean that you should.


You can use a salt system with other pool types, but we don't recommend using salt chlorine generators if you have metal pool walls.


Salt plus metal equals corrosion, and that just shortens the lifespan of your pool.


If you have a plaster-based surface in your pool, the salt could wear it down faster than it would wear down on its own (just using chlorine). More wear and tear on this type of surface means you’ll probably have to resurface your pool a lot sooner... and that can get rather expensive.


Fiberglass pools, on the other hand, work well with salt systems. The same surface qualities that make fiberglass low-maintenance and algae-resistant also help its surfaces hold up to salt water. If you'd like to install your own salt system, click here to check out our review of some top salt water systems for pools of all sizes.


Fiberglass pools are attractive

This might be more of a subjective opinion than an unarguable fact... but we'd love for you to browse our pool gallery, so you can see for yourself just how beautiful a high-quality fiberglass pool can really be.


Fiberglass pools (at least those made here at River Pools) come with multiple surface color options, and can also be customized with your waterline tile of choice.


Fiberglass pools also have sleek, smooth surface finishes and can utilize a range of attractive coping options.

Fiberglass pools have built-in features

Want a tanning ledge, bench seating, or a built-in spa?


That may cost extra when you buy other inground pool types.


Fiberglass pools include these features for no additional cost -- if you choose a model that happens to have them as part of their design. This means that you can get a pool with all the hottest features without worrying about racking up unexpected additional costs.

Fiberglass pools are manufactured in a controlled environment

Do you live in a "weird" or just plain unpredictable climate? Are you worried about how the weather might impact the construction of your pool? Bad weather can have a real and generally unwelcome affect on pool construction depending on the type of pool.


The largest part of a fiberglass pool -- the pool shell -- is manufactured off-site in a controlled environment, so even the worst weather won’t affect the final quality of the swimming pool installed in your backyard.


We also allow our gelcoats to cure in a secure space at controlled temperature and humidity levels to achieve optimal strength and durability.


This process ensures every pool shell, for every model we sell, comes out of our warehouse with the same superior quality, whether it's going down the street or all the way to Utah.


Fiberglass pools can increase the resale value of your home

Not all swimming pools increase the value of your home. Fiberglass pools often do.


A pool considered to be more permanent often can contribute to the value of your home.


A fiberglass pool can increase your home’s value by around 5%. This always varies by home, region, and other factors, though.

Fiberglass pools can be installed above ground or semi-inground

Can’t decide if you want your pool fully inground, semi-inground, or completely above ground with a wrap-around deck?


A fiberglass pool can be installed practically anywhere and any way you want, even on the roof.

Fiberglass pools are more environmentally friendly

Fiberglass pools can save you lots of money in chemicals by helping you avoid the lifelong battle with algae that can plague other types of pools.


A nice byproduct of this benefit is it's easier on the environment, too.


If and when you decide to remove or replace your pool, the old fiberglass in your pool shell can even be recycled.


Fiberglass pools save money

Fiberglass is pretty durable, which helps you save a lot on long-term maintenance costs.


And because you never have to drain your pool to acid wash the surface or replace the liner, you won’t have to spend money to refill your pool either.


Fiberglass pools are flexible and strong

The earth doesn’t just move when there’s an earthquake.


In fact, it’s perfectly normal for the earth to shift subtly over time, which is often the reason structural and/or cosmetic cracks can appear in concrete pools.


Fiberglass is strong, but it's also flexible enough to withstand the earth's movement without any major damage to the pool shell.




Fiberglass Pool Cons

As we said, fiberglass pools aren’t perfect, and even if they were, they wouldn't be perfect for everyone.


Let's be up front about some common drawbacks fiberglass pools can present to pool buyers. We think you should know as much as possible about your pool before you buy it.


Fiberglass pool designs can be limited

There are a wide range of fiberglass pool designs to choose from. However you, as a customer, won’t get to take part in the process of designing your pool.


You can still choose the surface color and add-ons you want with your fiberglass pool shell, but you can't create your own custom shape, or have your pool built to a specific size and/or depth.


Let's say you want our L36 pool, but you'd rather not have a tanning ledge, and you want it to be a foot deeper. Unfortunately, we can't do this without building a whole new pattern and mold.


A lot of work goes into building a mold.


Each mold can produce hundreds of pools over its lifetime. It would be costlier for both the fiberglass pool manufacturer and the customer if a brand new pattern and mold were to be built for every person who wants to modify their pool design.


Fiberglass pools can’t be wider than 16 feet

Have you ever driven behind one of those trucks with an "oversize load" sign? This means whatever's hitched to the truck (i.e., a swimming pool, mobile home, etc.) is more than 8.5 feet wide. Shipping containers are built to stay within this limit, but many truck loads are nonetheless too big to fit in a container.


To get our oversize-load pools from our manufacturing plant to your home, we have to get permits and follow certain transportation rules.


Anything that exceeds 16 feet in width is classified as a superload.


Superloads are much harder to transport. They face significantly more regulations than oversize loads, require a more extensive government approval process, and may possibly even need a police escort. This is the main reason fiberglass pools are typically no more than 16 feet wide.


However, staying within these mandated width limitations allows us to ship our pools all over the country without much hassle.


Fiberglass pools are harder for DIY-ers

Fiberglass pools can be installed DIY, but we don’t recommend it since the process can be more challenging than it is for vinyl liner pools (despite the fact that fiberglass pools essentially come in one piece).


For starters, it's often tricky to get the pool level (and it’s important!).


Pouring coping around a fiberglass pool can also be a challenge. We always recommend you at least consult with someone who has experience building fiberglass pools, if you really want to DIY the installation. In most cases, the money you might save by doing it yourself simply isn't worth the risk of an improper or incomplete fiberglass pool installation.


DISCLAIMER: While some fiberglass pool manufacturers do sell direct to homeowners, River Pools fiberglass pools are not available to purchase for DIY projects.


Fiberglass pools usually cost more than vinyl liner pools

On average, fiberglass pools generally cost between $40,000 to $100,000, and can easily cost more for a turnkey professional installation. A professionally installed vinyl liner pool, on the other hand, typically costs between $45,000 and $70,000 on average, with turnkey packages potentially running more.


If your main goal is to have an inground pool for as little money as possible, vinyl liners might be a more attractive option. However, it’s important to keep in mind the lower lifetime costs of fiberglass pools, and also their potential to increase the resale value of your home.

Repairs on some colored finishes don’t always match

If your gelcoat needs a small repair for any reason, the repaired area may not exactly match the color on the rest of your pool shell.


Fiberglass pools can fade slightly over time, and the repaired area might stand out a bit more than you might like it to be. A fiberglass pool's gelcoat may fade very slightly and at a very slow rate, but a fresh gelcoat patch can be obvious, depending on its placement (and other factors).


You can’t resurface the entire pool with gelcoat

You might be able to make small gelcoat repairs on your fiberglass pool, but it's really impractical to resurface the entire pool with a fresh gelcoat.


Gelcoat provides a durable and attractive finish, but to cure properly, it needs to sit, or cure, at a certain temperature -- approximately 77 degrees Fahrenheit -- in a controlled environment.


Since your pool is already in the ground (and is probably) outdoors, this won’t be an option.


Fiberglass pools can get osmotic blisters

Osmotic blisters remain a problem for many fiberglass pool manufacturers. We’ve found a way to beat this... but what is an osmotic blister, anyway?


Osmotic blisters are usually described as small bumps or bubbles in the surface of a pool shell.


They form when water molecules get trapped behind the gelcoat layer, causing a chemical reaction with resin in the pool shell. Osmotic blisters won't compromise the structure of a fiberglass pool, but they do degrade its finish and can be rather unattractive.
