We’re not psychics, but we’re guessing you’re thinking about getting a fiberglass pool kit.
Good guess, huh?
While we don’t have mind-reading superpowers, we are pretty knowledgeable about inground fiberglass swimming pools. Since you’re looking for information on fiberglass pool kits, like how much they cost, what they include, and mistakes to avoid, we want to help you out by sharing as much of our knowledge as we can.
In this article, you’ll learn about fiberglass pool sizes, costs, materials, and more, and we hope that it can give you a better idea of whether buying a fiberglass pool kit is the right choice for you. Let’s start by breaking down what’s included in a standard fiberglass swimming pool kit.
What’s included in a fiberglass pool kit?
Your fiberglass pool kit will come with a few essentials, depending on who you buy it from. Typically, it will include:
- The pool shell
- Pump and filter system
- Some hardware
- Dig sheet
- Instructions
Some kits may also include:
- An automatic chlorinator or saltwater chlorinator
- Plumbing equipment
- Chemicals
- Pool cover
- Shipping costs
What’s missing from a fiberglass pool kit?
Depending on who you buy it from, you can get either the bare necessities or almost everything you need to install your pool. However, there’s still a lot that you probably won’t get from any fiberglass pool manufacturer or seller, and these are absolutely necessary to fully complete your inground pool project.
The things that you likely won’t get from a fiberglass pool kit include:
- Backfill material for around your pool
- Concrete
- Coping and patio materials
- Heater or chiller
- Equipment to install the pool
- Water to fill the pool
- Plumbing pipes
- Hand tools
- Extra features like bubblers or waterfalls
While many fiberglass pool kits are comprehensive, including things like saltwater generators, chemicals, or a pool cover, most are pretty basic. You’ll find that almost no fiberglass inground pool kit will include concrete, backfill material, or the actual equipment and tools that you need to get the installation done.
You might think that the patio is an easy DIY job if you’ve worked with concrete, pavers, or other decking materials before, but it’s the coping that’s the tricky part. Be sure to find someone who has done fiberglass pool coping before to help you out.
Fiberglass pool kit prices
To give you a rough idea, a small fiberglass pool shell alone might cost between $10,000 and $20,000, a medium-sized fiberglass pool shell might cost between $20,000 and $30,000, and a large fiberglass pool shell might cost between $30,000 and $40,000.
As you probably figured out, the pool shell is the first major thing that will determine the cost of your fiberglass pool kit. Your swimming pool shell cost will be determined mostly by size, but it also varies by the manufacturer and the quality of their materials.
A quick note on fiberglass pool sizes: Small pools are usually in the 10x20 to 12x24 size range. Medium pools might fall between 15x30 and 16x32 feet, and large pools might be in the 16x40 to 20x40 range (Keep in mind that fiberglass pools can only be about 16 feet wide due to shipping requirements.)
Speaking of shipping...don't forget about shipping costs! Most manufacturers will not transport something as large as a fiberglass pool shell for free unless it's included in the kit price. You can expect to tack on an additional $2,000 to $5,000 or more to ship the pool to your home, depending on where it’s coming from.
As we explained in the first section of the article, not all pool kits include the same things. The price will definitely be affected by the amount of accessories and equipment that come with your pool shell, but at the very least, you can expect to pay up to $2,000 or more for your pump and filter system.
Fiberglass pool kits for DIY projects
People who buy fiberglass pool kits are typically those who want to DIY the pool installation. While this can help you save money, it’s important to keep in mind that you can risk damaging your pool or make critical installation errors, especially if you have no experience. You might also void your warranty if you don't install it according to the manufacturer's instructions.
In our expert opinion, it would be best to hire a fiberglass pool installer or find someone who has lots of experience in this area to help you out.
What are my small fiberglass pool kit options?
A lot of people inquire about fiberglass pool kits because they want to save money. For this reason, the small fiberglass pool kit is one of the most popular because it tends to be the most affordable.
With most fiberglass pool manufacturers, you’ll find a variety of small swimming pool designs to choose from, including freeform and linear. You’ll also find plenty of designs that have built-in features like tanning ledges and spas, even on the smallest models.
So, if you really want to invest in a small fiberglass pool kit, you’ll have no shortage of options to choose from a variety of fiberglass pool manufacturers.
Where can I get a fiberglass swimming pool kit?
Here’s one thing that you may find while shopping around for a fiberglass pool kit: not all manufacturers offer pool kits for sale. While every manufacturer sells swimming pools, you’ll find that some will only sell the pool if it’s going to be installed by a professional. This is a policy that is normally instated to ensure that the customer gets the best experience possible with their fiberglass swimming pool.
Keep in mind: A fiberglass pool installation is not an easy DIY project. We would compare it to building a house. This project will require a lot of equipment, plumbing work, electrical work, and other hidden factors that can turn your fun DIY project into a major headache. It takes practice and expertise to do it right.
But don’t get us wrong! If you’re a home improvement king or queen and you have the resources and experience to do it, we won’t deny you the savings or bragging rights that you get from installing your own pool. Just consider getting help from an experienced contractor if you have any doubts.

Frequently Asked Questions About Fiberglass Pool Kits
Are fiberglass pool kits worth it?
Fiberglass pool kits can save money upfront, but they come with challenges. If you have excavation, plumbing, and concrete experience, a kit might work for you. Otherwise, mistakes during installation can lead to costly repairs that outweigh the savings.
How much does a fiberglass pool kit cost?
Expect $10,000–$20,000 for small shells, $20,000–$30,000 for medium, and $30,000–$40,000 for large. Add $2,000–$5,000 for shipping and $2,000+ for pump and filter systems. Costs increase with accessories and additional equipment needed for installation.
Can I install a fiberglass pool kit myself?
You can, but it’s complex. Installing a fiberglass pool requires excavation, precise leveling, plumbing, electrical work, and backfilling. DIY installation risks cracking or improper leveling, and many warranties require professional installation to stay valid.
How long does it take to install a fiberglass pool kit yourself?
If you have experience, a DIY fiberglass pool installation might take 2–4 weeks, depending on weather, inspections, and your schedule. For first-time installers, delays can extend the timeline significantly due to equipment issues, mistakes, or learning curves.
Will I actually save money installing a fiberglass pool kit myself?
You may save on labor, but costs for equipment rental, materials, and potential mistakes can add up. Many homeowners find the upfront savings are offset by long-term issues if the pool is not installed correctly, impacting the pool’s lifespan and warranty coverage.
What are the most common mistakes with fiberglass pool kits?
Common issues include improper leveling, inadequate backfill compaction, plumbing mistakes leading to leaks, cracking due to ground movement, and coping errors. Many homeowners underestimate the precision required for a successful installation.
What sizes do fiberglass pool kits come in?
Fiberglass pool kits range from 10x20 feet to 16x40 feet, with 16 feet being the widest due to shipping limitations. You can find small, medium, and large designs with various depths, shapes, and integrated features like tanning ledges or built-in spas.
Do fiberglass pool kits include warranties?
Most fiberglass pool shells come with a manufacturer’s structural warranty. However, DIY installation errors can void this warranty if the installation doesn’t meet the manufacturer’s guidelines. Always confirm what’s covered before purchasing a kit.
Is a fiberglass pool kit the best choice for me?
If you want a lower upfront cost and have significant DIY skills, a fiberglass pool kit could be an option. However, professional installation often ensures warranty protection, correct leveling, and long-term peace of mind for your investment.

From the Manufacturer
At River Pools, we design and manufacture premium fiberglass pool shells, but we do not sell them for DIY installation projects. Why? Because we believe that proper installation is just as important as the quality of the shell itself.
Installing a fiberglass pool requires specialized knowledge, heavy equipment, and exacting methods that impact long-term performance. That’s why we work exclusively with installers who understand the intricacies of installing fiberglass pools.
We know the idea of installing your own pool can be appealing, and we’re here to help you understand the process. But if you choose to go the DIY route, it’s important to do your research and know what’s involved, because shortcuts during installation can lead to costly problems down the road.
