Selecting the right in-ground pool for your yard is an important process. In-ground pools are an investment, and whether you’re interested in a concrete, fiberglass, or vinyl pool, you want to make sure you’re happy with your decision. From maintenance and installation costs to style and design, here are the three most common types of in-ground pools and how to choose between them.
Factors To Consider When Choosing an In-Ground Pool
Unlike most above-ground pools, in-ground swimming pools and spas are a permanent installation, making them a more lasting feature of your yard. That means it’s even more important to consider what you want out of your in-ground pool before you start landscaping. Here are some things to keep in mind:
- Budget: How much are you willing to spend on installing an in-ground pool?
- Appearance: Different types of in-ground pools will look different in your yard. Concrete pools with tile or stone are endlessly customizable, while vinyl pools offer a classic appearance.
- Longevity: Some in-ground pools will last longer than others. A concrete pool can last up to 50 years or more, but a vinyl pool liner requires replacement every 5 to 9 years.
- Installation Time: Are you willing to wait for the perfect pool to be installed, or are you looking to dive in ASAP?
- Maintenance Requirements: Are you looking for a low-maintenance option, or a pool you can invest more time and money in down the line?
- Size and Shape: Some pool styles are limited in the size and shape you can choose.
- Chlorine vs. Saltwater: While chlorine pools can come in all varieties, saltwater pool systems work best in fiberglass or vinyl pools.
3 Common In-Ground Pool Types
If you have a crystal-clear vision of what you want from your in-ground pool, it’s time to choose what type to install. Here are the three most common types of in-ground pools, and some pros and cons for each.
- Fiberglass
- Vinyl Liner
- Concrete
Fiberglass

Fiberglass pools are sold as one-piece fiberglass shell units in different shapes and sizes. These are delivered to your home and installed by crane into the excavated hole for your pool. Because they come pre-made, there are some limitations on the appearance of your pool, and custom options are rare. Installation typically occurs in less than 2 weeks.
Fiberglass pools also won’t need acid washing or deep resurfacing like concrete pools. However, fiberglass pools may require a topical recoating depending on how well you maintain the pool over the years.
Fiberglass swimming pools are a good option for saltwater systems.
Cost
Their shipping and delivery system means that fiberglass pools are expensive to install upfront, with an average cost $47,000, and a typical range between $24,335 and $70,000. Over time, though, you’ll spend less on maintenance, as the slick, non-porous surface is resilient and resistant to algae. If properly maintained, a fiberglass pool will last 30 years or more.
Pros of a Fiberglass Pool | Cons of a Fiberglass Pool |
Low maintenance costs over time | High upfront installation costs |
Saltwater compatible | Only available in certain shapes and sizes |
The fiberglass surface resists algae growth | Usually won’t last as long as a concrete pool |
Fastest installation time | Some fiberglass pool finishes are slippery |
Lasts longer than a vinyl-liner pool | May eventually require resurfacing, depending on how well the pool is maintained. |
Does not require acid washing | |
More durable than vinyl liner pools | |
If properly maintained, you might never need to resurface your fiberglass pool |
Vinyl Liner

Vinyl liner pools are mounted into metal frames supported by a pool of sand in the bottom, as well as “coping” that seals in the liner at the top. You can customize their shape and size – especially if you’re looking for a more complex pool design that a fiberglass pool can’t offer.
Vinyl pools can also be saltwater compatible. However, if the pool has aluminum or steel walls, the saltwater may damage the metal.
Compared to fiberglass pools, vinyl liner pools typically have high maintenance costs. Why? Because their liners deteriorate easily. The average vinyl pool lining will last between 5 and 9 years, and liner replacements add up over time. On average, vinyl liner replacement costs between $2,250 and $4,535.
Vinyl pools aren’t as durable as fiberglass or concrete pools, so keep pets away from the pool. Otherwise, their sharp claws may tear the liner.
Pro Tip: Precise chemical balancing of your chlorine levels can extend the life of your vinyl pool liner, and opting for a model with fungus and UV protectors can also help.
Cost
Vinyl liner pools are the cheapest type of in-ground pool to install upfront, meaning you’ll save money, time, and headaches on pool construction. Typically, vinyl pool installation costs between $24,000 and $44,000. It takes about 2 to 5 weeks to install a vinyl pool, which is longer than fiberglass installation, but shorter than concrete.
Pros of a Vinyl Liner Pool | Cons of a Vinyl Liner Pool |
Cheapest in-ground pool type to install | Higher maintenance costs than fiberglass pools |
Customizable shape and size | Needs precise chemical balancing to protect the vinyl liner |
Opting for fungus/UV protectors can extend pool life | Not as durable as fiberglass or concrete |
Takes less time to install than a concrete pool | Not pet-friendly |
Does not require acid washing | Takes longer to install than a fiberglass pool |
Can be saltwater compatible | Requires vinyl liner replacement every 5 to 9 years |
Vinyl liner is susceptible to algae growth |
Concrete

Concrete pools or gunite pools are the most sought-after variety among prospective pool owners, as these are the most durable and long-lasting pool types. These pools consistently balance pool cost with durability and appearance. To build them, concrete is laid into your backyard pool excavation site, where it’s supported by steel rods and sculpted into whatever shape you wish.
Concrete pools can last 50 years or more if maintained properly. Concrete pools are susceptible to algae and are rather high maintenance. Expect to pay for an acid wash every 3 to 5 years, with costs typically ranging between $525 and $1,775.
Cost
Concrete pools are expensive to install. Most homeowners pay $52,990 on average, with concrete pool installation costs typically ranging between $31,000 and $71,665. You’ll need to take good care of your pool to make the most out of this investment, with regular cleaning, brushing, and chemical balancing. Expect to replaster the pool every 10 years.
Pros of a Concrete Pool | Cons of a Concrete Pool |
Highly durable | High maintenance costs |
Easily customizable in shape, size, and color | High installation costs |
Doesn’t corrode/oxidize; becomes stronger over time | Installation may take 6 to 12 weeks or more |
Has multiple finish options, including tile, plaster, exposed aggregate, and stone. | May require replastering every 10 years |
Can last up to 50 years or more | Susceptible to algae growth |
Typically has a rough surface texture that can scrape swimmers | |
Saltwater can damage the concrete |

FAQ About In-Ground Pools
The best pool for you depends on your needs and priorities in an in-ground pool. Concrete pools tend to balance durability with customization. Fiberglass pools are quick to install and have low maintenance costs. If you’re on a tight budget and want to customize the pool’s shape and size, vinyl liner pools might be the answer.
On average, professional pool maintenance costs homeowners $2,000 to $4,035 per year.
Fiberglass pools are the easiest pool type to maintain, as they aren’t prone to algae growth. Their maintenance costs are low in the long-term, considering you have to replace a vinyl pool’s liner every 5 to 9 years, acid wash a concrete pool every 3 to 5 years, and replaster a concrete pool every 10 years. Resurfacing a fiberglass pool is sometimes necessary, but not always.
