How Much Does A Semi-Inground Pool Cost?
The installation of a semi-inground pool typically comes with a price range spanning from $7,000 to $25,000, with an average expenditure of approximately $12,000. If you opt to lower a small above-ground pool to create a semi-inground configuration, the cost averages around $5,000, while elevating an in-ground pool to transform it into a semi-inground pool can run you up to $27,000.
This term, “semi-inground,” is used because the majority of the pool is situated below ground level, with just a few inches protruding above the surface. While this concept might appear unconventional to some homeowners, it offers a blend of benefits. In essence, it grants you the resilience and quality associated with traditional in-ground pools, combined with the cost-effectiveness found in above-ground pools.
This comprehensive pricing guide will delve into the various factors that influence the overall cost and explore additional services that can enhance your new semi-inground pool experience.

Breaking Down the Costs of Semi-Inground Pools
Semi-inground pools strike a balance—both figuratively and literally—between above-ground and inground pool options. They sit within a price range, level of permanence in your yard, and excavation time that falls somewhere in between these two alternatives. These pools are particularly well-suited for homeowners who aren’t quite ready to dive into the expenses of an inground pool, as well as those who appreciate the unique aesthetics they offer. Let’s delve into the details of estimating their costs.
Above Ground vs. Inground Pool Installation Comparison
Let’s clarify some common misconceptions. The category of semi-inground pools encompasses two distinct variations:
- Semi-above ground pool models, which are partially submerged into the ground.
- Semi-inground pools raised several feet above the ground.
Each of these options has its own set of advantages and disadvantages. When you sink an above ground pool into the ground, it provides a somewhat more permanent appearance, allows for greater pool depth, and tends to be more cost-effective on average. However, they typically lack the durability and longevity of inground pools that are raised and enclosed by a retaining wall. Raised inground pools offer a wider range of design possibilities, boast a longer lifespan, and integrate more seamlessly with your overall landscaping.
Labor
Typically, around one-third of the total installation cost is allocated to labor when installing a pool. On average, labor costs for semi-inground pool installation range from $3,000 to $7,000. It’s worth noting that sinking an above-ground pool a few feet into the ground generally requires less labor compared to constructing an inground pool raised above ground level.
Labor charges may also vary depending on additional factors such as plumbing, electrical components, and design elements that necessitate the expertise of a mason or retaining wall specialist. When contacting local pool installers, it’s advisable to obtain estimates from at least three different companies.
Materials
To better understand the cost breakdown of semi-inground pools, it’s essential to consider the materials used, specifically the liner and construction materials. Given the availability of both above-ground and inground pool designs, let’s examine the material costs associated with each category.
Types of Inground Pools
As reported by HomeAdvisor, the materials required for constructing a fully inground pool typically range from $21 to $72 per square foot. For the three common types of pool liners, the costs are somewhat lower when the pool doesn’t require extensive excavation.
Vinyl
Vinyl pool liners are adaptable, fitting a variety of unique pool shapes, and they come with a more budget-friendly installation cost. For a semi-inground pool liner made of vinyl, you can expect to pay an average of $25 per square foot. Keep in mind that vinyl liners typically require replacement every 10 to 15 years, with an average replacement cost of $2,500.
Fiberglass
Fiberglass semi-inground pool liners fall within the price range of $35 to $70 per square foot. Fiberglass pools offer a lifespan of up to 25 years, require less maintenance, and provide a moderate-cost option for semi-inground pool installation. It’s worth noting that custom shapes may incur additional expenses due to size and shape restrictions.
Concrete
Concrete pools boast the longest lifespan, lasting up to 75 years. However, they come with the challenge of demanding and expensive maintenance. Expect to invest between $55 and $75 per square foot for semi-inground concrete pools. On the upside, concrete pools offer extensive customization options, allowing you to enhance your pool’s aesthetics with tiles and stone.
Types of Above-Ground Pools
Many homeowners prefer a more permanent installation for their above-ground pools, offering affordability in materials while complementing their landscape. The average cost of an above-ground pool, including installation, ranges from $1,000 to $6,500. Typically, you’ll encounter flat-rate pricing for above-ground pools, rather than calculating costs on a per-square-foot basis.
It’s important to note that while lower-cost options like inflatable above-ground pools are available, only robust frames made of materials such as steel, resin, and aluminum are suitable for semi-inground designs. Additionally, be aware that semi above-ground pools often incur higher long-term maintenance expenses and have shorter lifespans.
Steel
Materials for an average-sized steel-framed pool generally cost between $800 and $3,500. Steel is not only the most budget-friendly option but also offers robust support for semi-inground installation, although it may be susceptible to rust over time.
Resin
Resin materials for semi-inground pools typically fall within the range of $1,000 to $3,500. The advantage of resin is its resistance to rust and oxidation, as well as its ability to avoid overheating, unlike steel. However, it can be more prone to cracking and wear over time.
Aluminum
For an investment ranging from $1,000 to $5,000, aluminum pools provide the same rust-resistant benefits as resin and even greater strength against extreme temperatures.
Pool Size
As expected, the size of your semi-inground pool directly influences the expenses for both labor and materials. Typically, pre-fabricated pool shapes in standard sizes tend to be more budget-friendly compared to custom measurements. Generally, semi-inground pools range from three to eight feet in depth, allowing for customization based on your preferences.
When it comes to selecting your pool design, size plays a crucial role. Let’s explore the most prevalent dimensions for both inground and above-ground pools.
Inground
Standard inground pool dimensions encompass shapes such as squares, rectangles, circles, and ovals. Assuming an average cost of $50 per square foot for semi-inground pool materials and $5,000 for labor, here’s an estimate of what you can expect to pay for some common shapes and sizes.

Above Ground
Above-ground pools are usually available in predefined shapes. We’ll provide their standard pricing based on size, along with an average labor cost of $5,000.
Site Preparation
For residential excavation associated with an inground swimming pool, the typical cost falls within the range of $400 to $1,500. In the case of a semi-inground pool, the average cost is generally lower than that of a fully inground pool. However, you might incur additional expenses for land leveling, especially if your terrain is uneven. These pool designs are well-suited for sloped lawns because of the wall’s exceptional stability. Nonetheless, it’s advisable to consult a local specialist to ensure that the ground is robust and level enough to support both the water and the pool structure.
Location
Keep in mind that your construction team will require access to the site with large equipment. If your lawn has a steep slope or obstacles hindering access, you may end up paying more in terms of time and labor for your team.
Permits
The cost of obtaining building permits for outdoor projects typically ranges from $250 to $2,000. In most cases, your pool installation contractor will include this cost in their overall fee and handle the necessary paperwork with local authorities. However, if you plan to undertake the installation yourself, be sure to check with your local town office for permit requirements and associated fees.

Upgrades and Additional Features
When it comes to enhancing your semi-inground pool, you have a range of exciting options to consider. Here’s a closer look at some common upgrades that you might want to factor into your budget.
Pool Deck
The cost of a pool deck typically averages around $5,000 for a 900-square-foot deck, although the final price will depend on the deck’s material and size. You can opt to have the pool deck installed at the same level as the water or, alternatively, you can choose to accentuate the elevated wall of your semi-inground pool by keeping the deck at ground level.
Pool Fence
Pool fences are essential for safety, and in many cases, they are required by insurance companies. On average, you can expect to spend between $1,500 and $10,000 for a pool fence. Mesh pool fences are the most economical option, costing only $7 to $10 per linear foot, whereas a wrought-iron fence can range from $20 to $35 per linear foot.
Pool Lighting
Pool lighting design not only enhances the aesthetic appeal but also contributes to safety during your swimming sessions. The average cost for pool lighting installation falls between $450 and $1,700. It is advisable to incorporate lighting into your initial pool design to avoid the need for costly drainage and rewiring of the pool area at a later stage.
Pool Cover
Outdoor pool covers come at a price range of $750 to $2,500, contingent upon the material and closing mechanism employed. Even semi-inground pools require protection from the elements during the winter and periods of non-use. For added safety, you can consider a walkable pool cover, which typically costs between $600 and $2,300.
Pool Heater
The cost of a pool heater varies depending on factors such as the type and size of your pool, as well as the heater’s fuel source. Above-ground pool heaters typically range from $200 to $2,200, whereas inground pool heaters may cost between $1,800 and $6,500.
Pool Enclosures
Semi-inground pools are just as compatible with enclosures as other pool types. Constructing a complete pool enclosure has an average cost of $10,200. However, you have the option to select simpler, more economical enclosures starting at around $5,000. For those seeking a more advanced solution, retractable enclosure prices can reach up to $140,000.
Pool House
If you desire a space to relax between swims with refreshments, consider constructing a pool house adjacent to your semi-inground pool. The cost for a pool house typically ranges from $48,000 to $180,000 for a standard 300-square-foot area, encompassing both materials and labor. Prefabricated pool houses are available, starting at approximately $26,600.
Water Features
Additional water features such as fountains, waterfalls, and grottos generally add an average cost of $400 to $2,000. Slides and diving boards are also popular additions, contributing anywhere from $1,000 to $15,000 to the overall project cost.
Installing a Semi-Inground Pool on Your Own
Certainly, eliminating labor expenses can result in an average cost reduction of $5,000. However, it’s crucial to possess experience in handling excavation equipment before taking on such a project. Opting to forgo professional assistance may also entail the risk of creating an uneven or structurally compromised poolscape. If you plan to undertake any part of the installation yourself, it’s advisable to seek guidance from a professional.
Comparing DIY Installation Costs to Hiring a Professional
If you have the capability to install the semi-inground pool independently, the primary portion of your expenditure will be attributed to pool materials, which can range from $1,000 to $20,000. DIY excavation expenses will involve approximately $2,200 per week for renting the necessary equipment, in addition to the costs associated with obtaining local permits.
