Fiberglass Pools

What is a Fiberglass Pool?

A fiberglass pool shell is factory molded structure made entirely of fiberglass. Fiberglass pools can be constructed out of various fiberglass materials melded together. The pool shell typically ends up being around ⅜ inches thick compared to vinyl pools which are normally 4 inches thick and gunite pools which are typically 5-6 inches thick including the rebar.

Wait a sec, you may be thinking – if they are less thick, doesn’t that mean they are less durable? No, fiberglass is actually an ultra durable material. There are fiberglass pools that were installed in the 1960’s that are still in working operation today!

A fiberglass pool shell may travel by truck across the country to be delivered to the homeowners residence. On delivery day a pool contractor will schedule a crane to lift the pool shell over the excavation area.

Workers will manually hand fit the shell into the hole. The pool is then set and leveled. After plumbing has been run and connected to the pool equipment that will run the pool, it’s normally back filled. Tile and coping can come next and then the pool is filled and should be ready to swim after being properly treated.

Fiberglass pools are not like gunite pools and vinyl liner pools. They require a specific skillset. Many times pool contractors specialize in a particular pool type for a reason.

It’s important to ask your pool contractor the right questions before hiring a builder to install your fiberglass pool. Ask your pool contractor how they dealt with any of the following issues:

  • Leaks in plumbing lines and around jets and other pool fittings
  • Separation between the pool and patio
  • Bulges in the side walls of the pool
