Installing an inground pool is a significant investment and an exciting addition to any backyard. Whether you’re looking to create a relaxing backyard oasis or an entertaining space for friends and family, knowing how to install an inground pool is key to achieving your dream outdoor space. There are several types of inground pools, including fiberglass pools, vinyl pools, and gunite pools, each with its own installation process, cost considerations, and benefits. This guide will walk you through the essential steps of installing an inground pool, from the initial planning to the final touches, so you know exactly what to expect.
Step 1: Choosing the Right Type of Inground Pool
Before diving into the installation process, it’s crucial to choose the right type of inground pool for your needs, budget, and yard. The most common types of inground pools include:
Fiberglass Pools: These come pre-made in a variety of shapes and sizes. They offer a quick installation process and are low maintenance due to their smooth, non-porous surface. Fiberglass pool installation typically takes less time than other options.
Vinyl Pools: These pools feature a flexible vinyl liner, allowing for more customization in terms of shape and size. Vinyl pools are cost-effective but require liner replacement every 7–10 years.
Gunite Pools: Made from a mixture of sand, cement, and water, gunite pools are highly durable and offer endless customization options. However, the installation process is longer and more expensive.
Once you’ve chosen the pool type that fits your vision and budget, you’re ready to move forward with the installation process.
Step 2: Preparing the Construction Site
The first step in how to install an inground pool is preparing the construction site. This involves several key actions:
Select the Pool Location: Consider factors such as sun exposure, proximity to your home, and the layout of your backyard. Ensure the chosen spot meets zoning regulations, setback requirements, and is free of trees or underground utility lines.
Obtain Permits: Depending on your location, you’ll likely need to obtain building permits for the pool installation. This step is crucial to ensure your pool complies with local regulations.
Excavation: Once permits are in place, it’s time to dig the hole for your pool. The construction crew will use heavy equipment to excavate the area where the pool will be installed. The size and depth of the hole depend on the type of pool you’re installing.
Excavation can take a few days, depending on soil conditions and the size of the pool. During this phase, excess dirt is removed from the site to make space for the pool shell or frame.
Step 3: Installing the Pool Shell
The process for installing an inground pool depends on the type of pool you’re installing. Here’s a breakdown of the most common installation processes for fiberglass, vinyl, and gunite pools.
Fiberglass Pool Installation
For a fiberglass pool, the pre-fabricated pool shell is delivered to your site via a truck and lifted into place using a crane. Once the shell is positioned in the excavated hole, workers ensure it is level and aligned correctly.
After placement, the pool is partially filled with water to stabilize it while gravel or sand is packed around the outside of the shell. The plumbing system, including the PVC pipe and pool pump, is installed during this phase to ensure the pool’s water features, filtration system, and lights work correctly.
Fiberglass pool installation is known for its speed, with the entire process often completed in just a few weeks.
Vinyl Pool Installation
Vinyl pools require a steel or polymer frame to be installed in the excavated hole. After the frame is secured, a concrete or sand bottom is created to support the vinyl liner. The vinyl liner is then stretched across the pool frame and carefully fitted to ensure there are no wrinkles or air bubbles.
Once the liner is in place, the plumbing system and any additional features are installed. Like fiberglass pools, vinyl pools are relatively quick to install, but the liner will need periodic replacement over time.
Gunite Pool Installation
Gunite pools have a more involved construction process, making them the most customizable but also the longest to install. After excavation, the construction crew installs a rebar framework, which acts as the skeleton of the pool. A mixture of sand, cement, and water (gunite) is then sprayed over the rebar to form the pool shell.
Once the gunite cures, a finish of plaster, tile, or pebbles is applied to the pool surface, giving it a smooth and durable texture. Plumbing, water features, and lighting are also installed during this phase.
Gunite pools are highly durable and long-lasting, but the installation process can take several months from start to finish.
Step 4: Installing the Plumbing and Electrical Systems
No matter what type of inground pool you choose, a crucial step in the installation process is setting up the pool’s plumbing and electrical systems. The plumbing system typically includes the pool’s filtration system, circulation pump, and any additional water features like fountains or waterfalls.
PVC pipes are used to connect the pool to the plumbing system, ensuring that water is pumped into the pool, filtered, and recirculated efficiently. In addition to plumbing, the pool’s electrical system is also installed during this phase. This system powers the pool lights, heating equipment, and any automated features, such as a pool cover.
It’s important to work with licensed electricians and plumbers to ensure all systems are installed safely and up to code.
Step 5: Backfilling and Deck Installation
After the pool shell and systems are in place, the next step is backfilling. This involves filling the area around the pool with gravel, sand, or soil to support the pool structure and prevent movement. For fiberglass pools, backfilling happens gradually as the pool is filled with water to keep the pressure balanced.
Once backfilling is complete, you can move on to installing the deck around your pool. The deck provides a safe, non-slip surface for walking and lounging, as well as enhances the overall look of your backyard. Common deck materials include:
Concrete: A durable and versatile option that can be stamped, colored, or textured to create a variety of looks.
Pavers: These offer a more upscale appearance and come in various colors and shapes to complement your backyard.
Wood or Composite Decking: These materials create a warm, natural look and can be used to integrate the pool seamlessly into your landscaping.
Step 6: Finishing Touches and Landscaping
With the pool installed and the deck in place, it’s time to add the finishing touches. This may include installing water features like fountains, waterfalls, or jets to enhance the aesthetics and experience of your new pool. Additionally, pool lights can be installed to create ambiance and allow for nighttime swimming.
Landscaping is the final step in how to install an inground pool. Incorporating plants, trees, and other landscaping features around your pool will make your backyard feel like a true oasis. When planning your landscaping, consider factors such as privacy, shade, and maintenance. For example, trees with large root systems should be planted away from the pool to avoid damage to the plumbing and structure.
Step 7: Pool Maintenance and Care
After your inground pool is installed, it’s important to maintain it properly to ensure its longevity. Regular maintenance includes cleaning the pool, balancing the water chemistry, and checking the filtration system for any issues.
Different pool types have different maintenance needs. Fiberglass pools, for instance, are relatively low-maintenance due to their non-porous surface, which resists algae growth. Gunite pools, while highly durable, may require periodic resurfacing to maintain their appearance and functionality.
Additional Considerations
Cost: Installing an inground pool is a significant financial commitment. The total cost will vary depending on the type of pool, the size, and additional features such as decking, lighting, and landscaping.
Safety Features: Installing fencing, alarms, or pool covers is crucial for safety, especially if children or pets will be around the pool area.
Property Value: While installing an inground pool can enhance your lifestyle and provide endless fun, it can also increase your property value.
Conclusion: The Right Inground Pool for Your Backyard
Knowing how to install an inground pool helps you understand the complexities and time required for this backyard transformation. Whether you opt for a quick and low-maintenance fiberglass pool, a customizable vinyl liner pool, or a durable gunite pool, each pool type offers unique benefits. From selecting the location and obtaining permits to watching the installation process unfold, creating a backyard oasis with an inground pool is a rewarding investment that adds value to your property and lifestyle.
