Installing a Semi-Inground Pool

Updated: Jul 3, 2024

The average cost of installing a semi-inground pool is $12,000, with a typical range between $7,000 and $20,000. Several cost factors influence the final price, such as the pool's size and the materials used. Semi-inground pools are suitable for small yards, can be installed on steep slopes, and may even be a more cost-effective option than fully inground pools. Below are tips for obtaining an accurate estimate of your semi-inground pool installation costs.


Factors Affecting the Cost of Semi-Inground Pools

Semi-inground pools provide a practical middle ground between above ground and inground pools, offering advantages in terms of affordability, durability, and installation efficiency. They are an ideal option for homeowners who are uncertain about the investment required for an inground pool or who value their aesthetic charm. Below are some suggestions to assist you in improving your cost assessment.



Comparison Between Above Ground and Inground Installation

Let's clarify some confusion regarding semi-inground pools, which can be categorized as follows:





  • Semi above ground pool models partially submerged into the ground.

  • Semi-inground pools elevated several feet above the ground.

Both scenarios have their advantages and disadvantages. Submerging an above ground pool gives it a more permanent look, allows for deeper pool depths, and is generally more cost-effective. However, they are not as durable and long-lasting as raised inground pools with a surrounding retaining wall. Elevated inground pools offer more design flexibility, have a longer lifespan, and blend better with the landscape.

Considering the extra effort required to elevate an inground pool above ground level, this option usually comes with a higher price tag.




Labor

Typically, around one-third of the total cost of a semi-inground pool is allocated to labor expenses. The average cost for labor alone in installing a semi-inground pool falls between $3,000 and $7,000. If you opt for sinking an above ground pool a few feet into the ground rather than building an inground pool higher above ground level, the labor required will be less, potentially resulting in lower costs. Labor charges may also vary based on additional factors such as plumbing, electrical work, and specific design elements that necessitate


expertise from a mason or retaining wall specialist. When contacting local pool installation companies, it is advisable to obtain estimates from a minimum of three firms to compare prices and secure the most favorable offer.







Material



To pinpoint semi-inground pool expenses more precisely, focus on the liner and construction materials used. Considering the availability of above ground and inground pool options, let's examine the costs of pool materials in each category..



Pool Material

Total Cost

Aluminum

$4,000

Concrete

$22,000

Fiberglass

$15,800

Resin

$4,000

Steel

$3,000

Vinyl (liner)

$7,000



Size of the Pool

It goes without saying that the bigger your semi-inground pool is, the higher the costs for labor and materials will be. Prefabricated pools in standard sizes tend to be more affordable than custom-made ones. Typically, semi-inground pools range from three to eight feet in depth, based on your personal preferences.

Size plays a crucial role in selecting your swimming pool design. Here are the most popular semi-inground pool sizes and their average expenses.

Pool Size (diameter)

Average Cost

10 ft.

$7,000

12 ft.

$9,000

16 ft.

$14,000

20 ft.

$20,000

22 ft.

$22,000

24 ft.

$25,000



Costs for excavating a residential area for an inground swimming pool usually fall within the range of $400 to $1,500. Opting for a semi-inground pool is generally cheaper than a fully inground one, but if you select a semi-above ground pool because of sloped terrain, you might incur additional expenses to level the ground for the pool.

These pool designs are ideal for sloped lawns due to the wall's extreme stability, but you may need to call in a local specialist to ensure that the ground is sturdy and level enough to hold the water and structure.



Site Accessibility

Keep in mind that your construction crew will require access to the site using large equipment. If your yard has a steep slope or numerous obstacles hindering access, you may incur additional costs for manual excavation and pool installation instead of using heavy machinery.


Building Permits


The cost of building permits for outdoor projects like a semi-inground pool can range from $250 to $2,000. Normally, your pool installation contractor will take care of this expense and manage the required paperwork. However, if you are overseeing the installation personally, be sure to confirm the permit rules and expenses at your town's local office.
