If you’re dreaming of a backyard pool but aren’t ready to commit to the cost or construction time of a traditional inground option, a semi-inground pool may be the perfect solution. Combining the benefits of both above-ground and inground pools, semi-inground designs offer flexibility, aesthetic appeal, and cost-efficiency—especially for sloped yards or smaller spaces.
At Matley Pools, we regularly help Massachusetts and Southern New Hampshire homeowners explore their options and make informed decisions about pool installation. If you’re considering this style, understanding the true semi-inground pool cost and what influences it is crucial to planning your project. This guide covers what you can expect to spend, how to budget, and tips for building a pool that fits both your yard and your finances.
What Is a Semi-Inground Pool?
A semi-inground pool is installed partially below ground and partially above. This design offers several advantages, including:
- Better integration with uneven or sloped landscapes
- A more natural appearance than an above-ground pool
- Easier access and less excavation than a full inground pool
- Compatibility with decking and landscaping for a custom look
Semi-inground pools can be made from various materials, including steel, aluminum, or resin frames, and often feature vinyl liners. Some fiberglass models can also be adapted for semi-inground installation.
Average Semi-Inground Pool Cost
The cost of a semi-inground pool varies based on factors such as size, materials, installation complexity, and added features. However, most homeowners in Massachusetts can expect costs to start at $10,000 – $25,000 for a professionally installed semi-inground pool and go up from there depending on add-on features.
Factors That Influence Semi-Inground Pool Cost
1. Pool Size and Shape
Larger pools naturally require more materials, more excavation, and longer installation times, which increases the total cost. Round pools tend to be more budget-friendly than oval or rectangular shapes due to simpler framing and liner designs.
2. Material and Construction Type
Semi-inground pools come in a variety of construction types. Steel and aluminum wall pools are typically the most cost-effective, while fiberglass and high-end resin options come with a higher price tag but longer durability and aesthetic appeal.
3. Site Preparation and Access
Yard accessibility plays a major role in cost. A sloped yard may be ideal for a semi-inground pool, but difficult terrain, trees, or tight access can increase excavation or labor charges.
4. Permits and Local Regulations
In Massachusetts, building codes require specific permits for pool installations, including safety fencing and electrical inspections. These fees can vary depending on the town and project scope.
5. Features and Upgrades
Custom decking, water features, LED lighting, and automation systems all add to your project’s overall cost. While not essential, these features can greatly enhance your pool’s functionality and appearance.
Tips for Budgeting Your Semi-Inground Pool
Set a Clear Budget
Before choosing a pool, determine what you’re comfortable spending overall. Be realistic about what’s included in your budget and where you might want to prioritize additional features or upgrades.
Request a Site Evaluation
Have a professional evaluate your backyard before starting your project. At Matley Pools, our team provides onsite assessments to help determine what your property can accommodate and what installation challenges may affect cost.
Prioritize Essential Features
If you’re working within a tight budget, focus on essential components first—like a high-quality pool shell, durable liner, and a reliable pump and filter system. You can always add custom decking or lighting down the road.
Ask About Maintenance Costs
Semi-inground pools generally require similar upkeep to other pool types. Make sure you understand the ongoing costs of pool maintenance, including chemicals, electricity, and professional services.
Installation Process: What to Expect
A typical semi-inground pool installation follows these steps:
1. Planning and Permits
We begin with a consultation to discuss your vision, take measurements, and recommend the right pool type for your space. Once a plan is finalized, we handle the permitting process for you.
2. Excavation and Site Prep
Our team prepares your yard by leveling the area and removing soil for partial in-ground placement. The depth of excavation depends on the desired pool height above and below ground.
3. Pool Assembly and Wall Installation
Once the site is ready, we install the pool walls, floor, and support structures. This is followed by plumbing and electrical work for filtration, circulation, and lighting systems.
4. Liner and Water Fill
The custom vinyl liner is fitted into the pool shell, vacuum-sealed for a smooth finish, and the pool is slowly filled with water.
5. Decking and Landscaping (Optional)
Once the pool is operational, we can add decking, fencing, steps, or landscaping to complete the look and ensure safety.
Is a Semi-Inground Pool Right for You?
