Step-by-Step Fiberglass Pool Installation

Step 1: Plan and Get Permits

Look up utility lines so you don’t dig in the wrong place. This is the first and most important step in putting in a fiberglass pool.

Step 2: Excavate and Prepare the Site

Mark your digging area. Rent a digger or hire someone to excavate the hole. Dig it a little deeper than the pool height to allow for the base.

Level the bottom using sand or gravel. This helps support the pool shell and keeps it stable.

Step 3: Place the Pool Shell

When the pool shell arrives, use a crane or forklift to place it in the hole. Make sure it is level. Pool shell placement must be exact. Check levels from side to side and end to end.

Step 4: Connect Plumbing and Electric

Step 5: Backfill and Fill the Pool

As you fill the pool with water, also add sand or gravel around the outside. This keeps pressure on both sides. It stops the shell from moving.

Add water in layers. Watch for leaks. Keep checking the level.

Step 6: Finish with Coping and Decking

Step 7: Final Checks and Chemical Balance

Check everything again. Clean the water and balance the chemicals. Your pool is now ready.
