Thinking about transforming your backyard into a personal oasis? Installing an inground pool is one of the most exciting upgrades a homeowner can make—but it’s also one of the most complex. One of the first questions people ask is: how long does it actually take to install an inground pool?
The answer depends on several factors, including the type of pool, your location, weather, permits, and custom features. Let’s break it down.
Typical Installation Timeline
Here’s a general overview of how long each phase might take:
| Phase | Estimated Time | Details |
|---|---|---|
| Planning & Design | 1–4 weeks | Includes choosing pool type, layout, features, and getting quotes. |
| Permits & Approvals | 2–6 weeks | Varies by municipality; some areas move faster than others. |
| Excavation | 1–3 days | Digging the hole for your pool. |
| Pool Shell Installation | 1–3 weeks | Depends on pool type: fiberglass is fastest, concrete takes longest. |
| Plumbing & Electrical | 1–2 weeks | Installing pumps, filters, heaters, lighting, etc. |
| Decking & Landscaping | 1–3 weeks | Concrete, pavers, fencing, and final touches. |
| Filling & Final Inspection | 1–3 days | Water fill, chemical balance, and safety checks. |
Total Time: 6–12 weeks on average, but it can stretch longer depending on complexity and delays.
Pool Type Matters
- Fiberglass Pools: Pre-molded and dropped into place. Fastest option—can be done in 3–6 weeks.
- Vinyl Liner Pools: Moderate timeline—typically 6–8 weeks.
- Concrete (Gunite) Pools: Most customizable but slowest—often 8–12+ weeks due to curing time.
Factors That Can Delay Installation
- Weather: Rain, snow, or freezing temps can halt progress.
- Permit Delays: Some cities take longer to approve plans.
- Custom Features: Waterfalls, spas, lighting, automation, and landscaping add time.
- Contractor Availability: Peak season may mean longer wait times to start.
Final Thoughts
Installing an inground pool is a journey—but one that ends with endless summer memories. If you’re planning for a specific season, start early. Spring installations often begin in winter, and fall installs may need summer planning.
