Buying and installing a semi-inground pool costs $7,000 to $24,000 or $11,700, on average. Your total will depend on your pool’s size and shape, the materials used, and additional features such as decks or patios. Semi-inground pools sit partially below ground and are ideal for homes with sloping landscapes. Prices fall between those for inground and above-ground models.
Your pool’s materials, brand, landscape, location, and permits are the biggest price factors.
There are two ways you can install a semi-inground pool:
Sinking an above-ground pool: Less expensive, but with less durability and visual appeal.
Raising an in-ground pool: More expensive, but with better durability and visual appeal.
The method you choose will affect your options for pool materials. Materials for an in-ground pool will cost $25,000 or more. Above-ground pool installation costs vary depending on which material you choose:
Above-Ground Pool Materials
In-Ground Pool Materials
Vinyl liner: $21 per sq. ft.
Fiberglass: $35–$66 per sq. ft.
Concrete: $55–$72 per sq. ft.
Different pool brands vary in quality, and higher-quality pools tend to cost more than low-quality pools. Only some above-ground brands make pools suited to work semi-inground. Check with each manufacturer to see the unit’s capabilities before trying to place part of it underground, and talk with a semi-inground pool dealer to find the cost for each brand.
The bigger your pool, the higher your costs due to the increase in materials and labor required to excavate and install. If you’re looking to save, try converting a small above-ground pool kit or opt for a smaller in-ground style.
|Size in Feet||Average Cost|
|12x52 round||$2,250 – $4,000+|
|15x52 round||$2,400 – $4,500+|
|21x52 round||$2,700 – $5,400+|
|15x24x52 oval||$3,500 – $6,700+|
|17x32x52 oval||$4,800 – $7,900+|
If part of your property’s terrain makes installation difficult for the type of pool you’ve selected, your pool installers may need to adjust the slope or grade of your yard to get the ground properly prepared. Semi-inground pools tend to work well in sloped yards, with the slope adding to their visual appeal.
If the site where you want to build a pool is difficult to access, it will be harder for your installation pros to get the work done. This will increase the time required, as well as your labor costs, especially if your pro needs special equipment such as a crane to complete the job.
Chances are, you need a permit to install a semi-above-ground pool. Check with your local government to learn about required permits for this project and how much building permits cost.
Total semi-inground pool prices range from $7,000 to $24,000, including materials and labor. This includes the price to excavate land, install the pool, wire electricity, pour cement, and add decorative elements such as lights, heaters, water features, retaining walls, bar space, stamped concrete, stonework, and more. These can push the price of your project toward the higher end.
To get a more accurate estimate for your partial in-ground pool cost, consider the costs of the following factors specific to your project.
Chemicals, cleanings, and professional pool services will cost around $115 per month. Costs vary depending on the frequency of cleaning and whether you have a raised in-ground pool or a sunken above-ground pool. The average pool owner spends $1,080 to $1,800 per year on professional pool services, but you can save if you do pool maintenance as a DIY job.
Apart from the pool itself, you can pay more for a few add-ons and create a relaxing retreat around your pool. Some common semi-inground pool add-ons include:
Decking: $10–$30 per sq. ft.
Heater (Above-Ground Pool): $170–$2,200
Heater (In-Ground Pool): $1,840–$6,490
Enclosures: $200 per sq. ft.
You can use a variety of landscaping techniques to create the perfect backyard space around your semi-inground pool. Some common landscaping installation costs around pool areas include:
Retaining Walls: $4,030–$8,720
Pathways: $10–$30 per sq. ft.
Flower Beds: $650–$3,000
Trees and Bushes: $25–$3,000
Outdoor Kitchen: $5,060–$17,280
Sod Lawn: $0.90–$1.80 per sq. ft.
Labor alone for a semi-inground pool installation is $3,000 to $7,000 or more, on average, so you could save thousands doing the project as a DIY. However, a semi-inground pool should never be a DIY project unless you have specific training and experience with the heavy machinery required.
Even with experience, hiring a pro remains the wisest option; the work is highly labor-intensive, and mistakes can cause major property damage.
Although not recommended, if you do wish to attempt a DIY semi-inground pool installation, you’ll need to cover the cost of the pool materials, equipment rental, and landscaping for your project. You’ll also need to account for the time you’ll spend digging out the hole, assembling the pool, and backfilling your yard. These costs can add up quickly, which is another reason it’s a better idea to hire a professional poll installer.
Above-ground pools cost from about $2,150 to $6,660. It costs an extra $4,660 to $18,350 to convert an above-ground model to a semi-inground unit on average.
A semi-inground pool is worth it if you want to save on the cost of an in-ground pool. Semi-inground pools cost more than above-ground pools, but they offer greater aesthetic appeal and durability.
Semi-inground pools typically last 10 to 20 years with adequate maintenance. Lifespan varies based on material and manufacturer. The average above-ground pool lasts seven to 15 years, while an in-ground concrete pool can last 50 years or more.
Pros can install semi-inground pools at various depths, ranging from three feet to an eight-foot deep end. Depth depends on the shape and size of the pool you choose to build, so talk to your pool installation professional about your goals and what’s possible within your budget.
