How Long Does it Take to Install a Fiberglass Pool?

pool installationYou’ve chosen the perfect new fiberglass pool for your family and approved the pool builder’s plans. You’ve scoured the internet for the coolest pool toys, floats and games. You’ve reviewed the rules of pool safety with the kids, so now you are wondering, “When will the pool be done?” 

The good news: fiberglass pools are often the quickest to install.

When it comes to getting a new quality fiberglass inground pool, the waiting is the hardest part. But relative to other pool types, fiberglass is a quick install. In fact, your new fiberglass pool could potentially be swim-ready in as little as three weeks! Vinyl liner pools can take up to eight weeks, and a concrete (gunite) pool can take up to six months. (But remember, every project is different, and your actual results may vary.)

So, let’s take a look at the fiberglass pool installation process overall, along with some guidelines for approximately how long each phase might take. However, you’ll also need to keep in mind that every pool installation is unique, and there are lots of variables, such as the accessibility of your site, your soil conditions, the weather, and local code requirements and inspections that can impact the process and your timeline.

Pre-Installation: Permit application and approval

Permit application and approval can take as little as a few weeks or as long as several months, depending on where you live. Since this part happens prior to any actual excavation, we don’t count it as part of how long it takes to install the pool. However, it’s important to allot time in your schedule for this process. It’s definitely not something that should wait until the last minute. Your pool builder should be handling the acquisition of the permits for you as part of the installation process, but they’ll need some documentation from you to get started.

Phase One (2-3 days, depending on weather): Site excavation and setting the pool 

Your pool builder will outline the pool’s dimensions for excavation using the dig specs for your pool design that the fiberglass pool manufacturer has provided them.

  • The excavated area will be dug about four inches deeper and about a foot larger than the diameter of the pool than necessary to allow for backfill material to be added under and around the pool.
  • Your pool builder will add the base material that your fiberglass pool shell will rest on and carefully level it.
  • Generally, pre-plumbing will be done at this time as well.
  • Your fiberglass pool shell will be set in the hole, using an excavator or a crane.

Phase Two (2-3 days, depending on weather): Installing the remaining plumbing, electrical and filtration system 

  • Your pool builder will install the pool pump and filtration system lines, as well as valves, and any other wiring needed for lights and other water features.

Phase Three (2-3 days, depending on weather): Backfilling the shell and filling the pool 

Your pool installation team will now add backfill around the outside of the pool shell while simultaneously adding water to the pool. It’s essential that these happen in tandem so that the pressure on the shell is equalized.

  • If you have purchased a fiberglass pool with a built-in tanning ledge that does not have the Backfill Eliminator ® technology, you’ll need to allow an extra day or so for the backfill process, as it’s more difficult to backfill the tanning ledge than any other part of the pool.
  • If you’re planning to have waterline tile, it would be installed at this point as well, which might add a day or two to your timeline.

Phase Four (Timing can vary greatly, based on your local government agencies’ schedules): Inspection 

  • Your pool installation must now be inspected by your local building and inspections department.

Phase Five (3-5 days, depending on weather): Coping, decking and auto-cover installation 

Your pool installation team will now install the coping around the edge of your pool.

  • If you’re having an automatic pool cover installed, they will complete the “pre-pour” portion of your pool cover installation.
  • Your pool area is now ready for whatever type of decking or pool patio you have chosen.
  • Once the concrete is poured and while it’s curing, your pool installation team will begin to clean up the site.
  • Once the concrete is cured, the post-pour installation of the automatic safety cover will be completed.

Phase Six (2-3 days): Clean up, water balancing and other add-ons 

  • Your pool installation team will remove their equipment and clean up the construction materials from your pool area.
  • Before you can swim, you need to make sure your pool water is safe, clean and healthy for your family. If your pool builder also offers pool maintenance service, you might ask them to help you get your water balanced for the first time. Otherwise, you may need to bring in a pool service pro to help you.

It’s done. Have a blast and make amazing memories with your family in your new fiberglass pool!
