If you’re dreaming of cooling off in your backyard luxury retreat this summer, one of the most pressing questions is: How long does it typically take to install an inground pool?
A well-installed inground pool is more than a backyard upgrade—it’s an investment in lifestyle, health, and home value. However, the installation process can be complex, time-consuming, and challenging to plan. In this comprehensive guide, we’ll walk you through each stage of the pool installation timeline, what factors can influence its duration, and how to ensure your project stays on track.
Understanding the Inground Pool Installation Timeline
Installing an inground pool is a multi-step process that involves planning, excavation, construction, and final touches. The average inground pool installation takes between 6 to 12 weeks, but the actual timeline can vary based on several key factors.
Table 1: Estimated Timeline Summary (By Step)
| Installation Step | Average Duration |
|---|---|
| Design and Planning | 2–4 weeks |
| Permitting and Approvals | 2–6 weeks |
| Excavation | 1–2 weeks |
| Pool Shell Installation | 1–3 weeks |
| Electrical and Plumbing | 1–2 weeks |
| Decking and Final Touches | 2–4 weeks |
Step-by-Step Breakdown of the Installation Timeline
1. Design and Planning (2–4 weeks)
Before any ground is broken, proper planning is essential. This stage sets the foundation for a smooth installation. During this phase:
- You’ll meet with a pool builder to discuss your preferences (shape, size, features, budget).
- A professional landscape designer or engineer may draft a custom design tailored to your property layout.
- Soil testing is often required to determine what kind of structural support your ground can offer.
Some homeowners may take a few extra weeks revisiting ideas, exploring materials, or waiting on quotes, which can extend this phase. Others may make quicker decisions, especially if they have a clear vision of what they want.
2. Permits and Approvals (2–6 weeks)
One of the most unpredictable parts of the timeline is acquiring necessary permits. Local zoning laws, neighbor approvals, utility locates, and building code requirements can extend the permitting process significantly.
In some regions, especially urban or densely populated areas, the waiting time for permits can drag on for a couple of months. Your contractor typically handles this, but it’s important to factor it into your planning.
3. Excavation (1–2 weeks)
Once permits are secured, the excavation process begins. Heavy machinery such as backhoes and excavators are brought in to shape the ground to the exact measurements of the pool.
The duration depends on the pool size, terrain, and soil type:
- Easy soils like sand or loam can speed the process up.
- Rocky or clay soils may slow excavation and even require blasting or special machinery, which can extend this by another 1–2 weeks.
This phase includes digging footers for walls and shaping slopes for drainage.
4. Pool Shell Installation (1–3 weeks)
The actual pool shell is one of the most critical installation phases. How long this step takes depends heavily on the type of pool being installed:
-
Concrete Pools (Gunite or Shotcrete): These are the most labor-intensive and longest to install. It involves building a steel rebar framework, spraying concrete, and then letting it cure. Curing alone can take 2–3 days before any further work can begin, but full structural curing can stretch over a few weeks. Concrete pools typically take 1–3 weeks for shell construction.
-
Fiberglass Pools: These come pre-molded and are set in place by crane. This process can often be completed in a single day. However, adjusting the structure around it and preparing for coating or tiling can stretch the time to about a week, depending on the installer’s pace.
-
Vinyl Liner Pools: These are quicker than concrete but slower than fiberglass. Installation involves placing the steel or polymer wall frame, leveling the base, and securing the vinyl liner. This typically takes 5–7 days.
5. Electrical and Plumbing (1–2 weeks)
After shell installation, the focus shifts to systems—pumps, filters, heaters, and lighting.
Key steps involved:
- Running electrical conduits for pool lights and control panels.
- Installing the filtration and water circulation systems.
- Laying gas lines or electrical heating systems for pool heaters.
- Setting up automatic pool covers or salt chlorination systems if requested.
This portion of the work generally takes 1–2 weeks, depending on complexity and local safety inspections.
6. Decking and Final Touches (2–4 weeks)
Once the pool body is finished, the surrounding area receives attention with:
- Pool deck installation (concrete pavers, stone, wood, etc.)
- Safety fencing or electronic gate installation
- Tile work and coping (edge stones around pool perimeters)
- Water filling and chemical balancing
- Landscaping touches
Decking, especially with premium materials like travertine or flagstone, can take extended time to complete. Additionally, wait times for specific tiles or deck materials can hold up this phase if not ordered early.
Factors that Influence Installation Time
While you can estimate that installation lasts between 6 and 12 weeks, several factors can alter that timeline:
1. Type of Pool
As briefly discussed, the type of pool has a major influence on overall duration. Fiberglass installations typically take the least amount of time (often under 6 weeks total), while concrete/gunite pools may stretch beyond 3 months.
2. Permit Delays
Depending on where you live:
- Heavily regulated areas like Los Angeles or New York can experience delays due to permit requirements.
- In rural areas, approvals may be faster but access to licensed contractors may extend other stages.
3. Seasonality and Weather
Pool installation is best done in the spring and early summer for a few practical reasons:
- Weather is dry, increasing safety and speed during excavation.
- Contractors are in high demand during this season, so scheduling earlier is crucial.
- Rain or soil instability can delay work and push back timelines significantly.
4. Location Accessibility
If your property has limited access (narrow gateways, tight backyard space, or a home built on retaining walls), installation can be more labor-intrusive, making heavy machinery setup and movement difficult.
This can add anywhere from a few days to 2 extra weeks.
5. Design Features and Customizations
Inground pools can include numerous extras, which all influence timelines:
- Integrated spas
- Waterfalls or fountains
- Custom tile designs
- Automated chemical systems
- Underwater lighting
Each of these can add extra days to the installation schedule or delay the project until specialty materials are delivered.
What You Can Do to Speed Up the Process
While some steps—like local permitting or weather—are outside your control, other actions can keep the project on schedule.
1. Start Planning in the Off-Season
Begin your design and contract planning during the fall or winter when pool contractors are less busy. This can give you:
– A better opportunity to customize your pool design.
– Quicker responses from contractors for scheduling.
– Priority access once the busy spring installation season begins.
2. Choose Fiberglass or Standard Concrete Designs
Opting for simpler, off-the-shelf fiberglass shell designs allows your contractor to schedule earlier and complete the installation faster. Custom concrete pool shapes with curved walls or multiple elevations will take longer to construct.
3. Secure Permits Proactively
While your contractor manages the permit process, you can assist by:
- Getting neighbors’ signatures in advance for Homeowners Association (HOA) notifications, if required.
- Promptly providing site maps or legal documents.
- Tracking progress to stay on top of local inspectors’ schedules.
4. Order Materials Early
Tile colors, deck materials, lighting systems, and liners can have lead times. To avoid delays:
– Finalize your color selections and extras early.
– Order materials before construction begins.
5. Minimize Last-Minute Changes
Requests to alter the pool layout, add features, or change materials mid-installation can cause scheduling holdups. Once excavation begins, major changes are costly and time-consuming.
Realistic Expectations by Pool Type
To help you determine the expected duration for your project, here’s a breakdown by pool type:
1. Fiberglass Inground Pools
- Total Average Duration: 6–8 weeks
- Main Time Drains: Permit delays and decking time
- Fastest Completion Time: As little as 4 weeks during off-peak months
Fiberglass pools come prefabricated and are quickly installed using a crane. While prep work still takes time, fiberglass installation skips many labor-intensive steps like pouring and curing concrete.
2. Concrete (Gunite or Shotcrete) Inground Pools
- Total Average Duration: 8–16 weeks
- Main Time Drains: Multiple curing intervals and elaborate design phases
- Slowest Completion Time: Occasionally exceeds 16 weeks depending on complexity
Concrete is the gold standard for luxury inground pools but involves the longest timelines. Once the shell is sprayed on-site, it needs multiple curing stages before plastering or tiling can begin.
3. Vinyl Liner Inground Pools
- Total Average Duration: 6–10 weeks
- Main Time Drains: Waiting for special-order vinyl liners
- Most Variable Component: Material order timing
Vinyl liner pools aren’t as long-lasting as concrete or fiberglass, but they offer a lower upfront cost and faster installation times depending on local labor availability.
Hiring the Right Contractor Matters
The experience and dependability of your contractor are central to the pool’s total installation timeline. A top-rated contractor can streamline scheduling, coordinate subcontractors, and proactively address delays.
When choosing a builder, look for:
– Online reviews and reputation
– Proper licensing and local code familiarity
– Past projects that resemble your dream pool
– Transparent communication and schedule visibility

How long does it typically take to install an inground pool?
The average time to install an inground pool is between 6 to 12 weeks, depending on several factors such as the type of pool, size, design complexity, weather conditions, and local permitting processes. Concrete pools usually take the longest, often 8 to 12 weeks, due to the time required for curing the material and finishing the surface. Vinyl liner and fiberglass pools can be completed faster, sometimes in as little as 3 to 6 weeks, especially when pre-manufactured components are used.
However, this timeline can vary significantly based on the level of customization, availability of labor and materials, and any unexpected site challenges such as rocky terrain or water table issues. Delays in obtaining permits or inspections can also add time to the process. Homeowners should discuss the expected timeline with their pool contractor to understand the specific schedule that applies to their project and location.
What factors influence the installation time of an inground pool?
Several key factors can affect how long it takes to install an inground pool. The type of pool is one of the most significant—fiberglass pools generally take less time to install compared to concrete or vinyl pools. The size and design of the pool also play a role, with larger or more complex shapes requiring more labor and planning. Soil type and site preparation can add days or even weeks, particularly if excavation is difficult or soil stabilization is needed.
External factors like weather and permit approvals can also slow down the project. Heavy rain or freezing temperatures can delay excavation and concrete pouring. Simultaneously, delays in obtaining city permits or passing inspections may push back the start of construction. Lastly, the efficiency and scheduling of the contractor and their subcontractors can influence the length of the project, so choosing a reputable and well-organized company is crucial.
Does the type of inground pool affect installation time?
Yes, the type of inground pool significantly affects installation time. Fiberglass pools are usually the fastest to install because they arrive pre-manufactured and can be placed into a prepared hole within a few days once excavation and site prep are complete. This process can be completed in roughly 3 to 6 weeks. Vinyl liner pools are typically installed in about the same timeframe, but this can increase if extensive framing and leveling are required for the structure.
Concrete (gunite or shotcrete) pools take the longest due to the need for building the structure from scratch, allowing time for the concrete to cure, and finishing the surface with plaster or other materials. The entire process can span from 8 to 12 weeks or more, especially if custom features or design elements are involved. Choosing the type of pool that balances your design preferences with time constraints is important when planning your installation.
Can weather impact the installation time of an inground pool?
Weather can have a considerable impact on the installation schedule of an inground pool. Heavy rain can cause delays by making the job site muddy and unsuitable for excavation or concrete pouring. Similarly, extreme heat can cause materials to dry too quickly, affecting the curing process and requiring adjustments in construction methods. Cold weather, especially freezing temperatures, can prevent the proper setting of concrete and plaster, which means installation must often pause during unfavorable conditions.
Contractors typically account for possible weather delays when providing a timeline, but unforeseen climate conditions can still prolong the installation process. Homeowners should be prepared for occasional setbacks and maintain open communication with their contractor to stay updated on any schedule shifts due to weather. Scheduling construction during milder seasons can help reduce the likelihood of weather-related delays.
Are permits required for installing an inground pool, and do they add time to the process?
Most municipalities require permits for the installation of inground pools to ensure that construction meets local safety, zoning, and building code requirements. Obtaining a permit can add anywhere from a few days to several weeks to the overall installation timeline, depending on how quickly the local government processes permit applications and whether any revisions are requested. Some areas may require additional approvals for electrical, plumbing, or fencing related to the pool as well.
To minimize delays, it’s best to have your contractor handle the permit process, since they are typically more experienced in navigating the requirements. Be sure to factor permit time into your project scheduling and plan any backyard events or personal timeframes accordingly. Being proactive in submitting documents and answering local officials’ questions can expedite the process.
Can a pool be installed during winter?
It is possible to install a pool during the winter, but it can present several challenges that may affect the installation time. Freezing temperatures can interfere with concrete curing and make excavation more difficult if the ground is frozen or muddy from rain or snow. Many contractors avoid starting projects during colder months unless the job site is properly maintained and heated when needed. Project timelines might also extend due to unfavorable weather conditions.
However, some homeowners begin planning and preparing during winter for a spring or summer installation. In areas with milder winters, construction can continue with minimal disruption. If you’re considering a winter installation, it is important to work with an experienced contractor who can manage cold-weather conditions effectively and ensure that all materials cure correctly. Communication and flexibility are key for ensuring a successful project under these circumstances.
Does working with a contractor affect how long it takes to install an inground pool?
Yes, the contractor you choose can play a significant role in the duration of your inground pool installation. A well-organized, experienced contractor with a reliable team and schedule can help ensure the installation moves efficiently and on time. They understand how to coordinate subcontractors, manage logistics, and handle permitting to reduce delays. Reputable companies can also anticipate obstacles and find solutions quickly to avoid unnecessary hold-ups.
On the other hand, working with an inexperienced or overbooked contractor could lead to miscommunication, scheduling conflicts, and poor time management, which can extend the installation period by weeks or even months. It is essential to review potential contractors thoroughly—checking references, verifying licenses and insurance, and reviewing project timelines—to ensure a smooth, timely installation. A reliable contractor is one of the most valuable elements in a successful pool-building experience.
