$7,000 – $25,000 average installed cost
Average semi-inground pool cost
A semi-inground pool costs $7,000 to $25,000 installed on average. The cost of semi-inground pool materials is $2,000 to $15,000, while the labor cost for semi-inground pool installation is $2,000 to $10,000. Semi-inground pools are ideal for sloped yards but not as customizable or long-lasting as fully inground pools.
|National Average Cost||$16,000|
|Average Range||$7,000 to $25,000|
Semi-inground pools typically refer to partially buried above-ground pools.
Some contractors raise an inground pool and surround it with a retaining wall, but that option costs more than average.
Semi-inground pool cost by size
The cost of a semi-inground pool installation depends mostly on its size:
|Pool size||Average cost (materials only)|
|12' round||$800 – $1,100|
|15' round||$900 – $1,800|
|18' round||$1,100 – $2,600|
|24' round||$1,700 – $3,200|
|12'x24' oval||$1,500 – $2,000|
|12'x24' rectangle||$1,500 – $4,500|
|18'x33' oval||$2,600 – $3,000|
Semi-inground pool cost by material
Steel is the strongest and most affordable material for semi-inground pools, while fiberglass and concrete are the most expensive. Inflatable or flexible above ground pools may cost less, but these pools are not strong or sturdy enough for semi-inground designs.
|Material||Average cost (materials only)||Details|
|Steel||$800 – $3,000||Durable but prone to rust|
|Resin||$900 – $3,500||Doesn’t rust but can fade or crack|
|Aluminum||$1,000 – $4,500||Lighter than steel but expensive|
|Vinyl||$6,300 – $8,400||Liner needs to be replaced regularly|
|Fiberglass||$10,500 – $26,400||Low maintenance and long-lasting|
|Concrete||$16,500 – $28,800||Most expensive option|
Semi-inground pool cost calculator
The cost to build a semi-inground pool depends on the materials, labor rates, shape, and other factors:
|Materials||$2,000 – $15,000*|
|Labor||$5,000 – $10,000|
|Total cost||$7,000 – $25,000|
*Including the pool and any retaining wall materials
Factors that affect the cost of installing a semi-inground pool include:
Shape – Small, round semi-inground pools tend to cost less than oval and rectangular pools.
Location – The construction team will be using large equipment. Costs increase if the path is too narrow, the slope is too extreme, or if there are obstacles in the way.
Time of year – Installing a pool during the fall or winter may cost less than during the pool industry's busy season.
Liner – A vinyl pool liner costs $3,000 to $7,500 for a replacement. Pools with liners typically need a replacement every 6 to 10 years.
Water –The cost to fill a pool with water is $4 to $10 per 1,000 gallons when you use a garden hose or $30 to $100 per 1,000 gallons for a water delivery service.
Maintenance – Professional pool maintenance costs $80 to $150 monthly. Smaller swimming pools require fewer chemicals, which reduces the overall maintenance cost. The support wall around semi-inground pools may also need maintenance or repairs over time.
Permit – Pool permits cost $100 to $300 on average. Contractors typically include the permit costs in their labor fees.
The labor to install a semi-inground pool costs $5,000 to $10,000 on average. Dropping an above-ground pool into the ground a few feet takes less work than constructing an inground pool and adding a retaining wall.
The installation may also require excavation, along with a plumber to run a water line and an electrician to run power to the pool pump.
Consider which features or add-ons you may want before hiring a contractor:

Semi-inground pool FAQs
What is a semi-inground pool?
A semi-inground pool is made by either partially burying an above-ground pool or partially raising an inground pool. They are popular in homes with sloped yards and take less time and money to install than fully inground pools.
How deep are semi-inground pools buried?
Installers typically bury semi-inground pools about 2 to 3 feet in the ground for a total depth of 3 to 8 feet on average. Some semi-inground pools have a shallow and deep end, while others have a single depth across the bottom.
Are semi-inground pools worth it?
Semi-inground pools are worth it if you want the appearance of an inground pool but the affordability of an above ground pool. Semi-inground pools typically cost less for excavation and installation, and you'll spend less to fill in the space if you choose to remove it later.
How long does it take to install a semi-inground pool?
Installing a semi-inground pool takes 2 days to 5 weeks to excavate, place the pool, and add a wall or enhancements. The project will take longer if you're building a deck or fence around the pool at the same time.
How long do semi-inground pools last?
Semi-inground pools last 7 to 15 years for quality above-ground pool materials with durable walls. If you use inground pool materials, they could last up to 75 years.
