What is a DIY Fiberglass Pool?

- Quick installation: Typically takes 1-2 weeks compared to months for concrete pools.
- Long-lasting: Fiberglass pools last for decades with minimal maintenance.
- Lower maintenance: Smooth surface prevents algae buildup, reducing chemical use.
- Energy efficiency: Less heating is required to be compared to concrete pools.

How to Install a DIY Fiberglass Pool
1: Choose the Right DIY Fiberglass Pool Kit
Before starting, select the right fiberglass pool kit based on the following:
- Size & Shape: Consider backyard space and depth requirements.
- Features: Some kits include skimmers, plumbing, and filtration systems.

2: Prepare the Site
- Obtain Permits: Check local zoning laws and acquire necessary approvals.
- Mark the Pool Area: Use stakes and rope to outline the pool shape.
- Excavate the Ground: Dig according to the pool’s dimensions, ensuring an extra 12-inch depth for the base.
- Level the Ground: Add a layer of gravel (6 inches) to support the pool shell.
3: Place the Fiberglass Pool Shell
- Use a Crane: Carefully lower the fiberglass pool shell into the hole.
- Check for Leveling: Adjust positioning to ensure a perfectly level installation.

6: Finalizing the Pool
- Install Decking & Coping: Choose concrete, stone, or wood decking.
- Adjust Water Chemistry: Test pH, chlorine, and Water balance levels.
