Fiberglass or Gunite Pool

When researching a pool, what’s very obvious is the wide variety of materials you have to choose from. Two of the most popular pool options are gunite vs fiberglass pools. This article is a comparison between these two popular pool materials by discussing the advantages and disadvantages of fiberglass pools and gunite pools. Read on to learn the difference between fiberglass and gunite pools.

Fiberglass Pools

Fiberglass pools are large, single-piece inserts that are dropped in to a hole dug on your property. They are less expensive than Gunite, but require more property to allow installation.


  • Easy to Clean and Maintain– smooth surface makes cleaning dirt and grime easy.
  • Easier on Pumps and Filters– A fiberglass pool’s surface makes it easier for pumps and filters to keep it clean.
  • No Liner– Fiberglass inserts are one continuous waterproof surface that doesn’t require a liner that needs replacing.
  • More Affordable– Fiberglass pools are the less expensive of the two options, usually costing between $9,000 and $15,000, depending on pool shape and size.


  • Prefabricated– Fiberglass pools are prefabricated inserts, so they can’t be customized beyond the shapes and sizes commonly available.
  • Difficult Installation– The fiberglass insert is large and has to be dropped in place. Installation of a fiberglass pool requires enough space for a flatbed truck and a crane.

Gunite Pools

Gunite (or concrete) pools are made of a concrete/sand mix with an underlying rebar structure. They are the most stable and permanent type of pool, but are also the most expensive.


  • Customizable– Poured concrete can be customized to endless possibilities. This is the best pool option for those looking for a truly unique pool that is truly them.
  • Durable– Gunite pools are made of concrete, one of the sturdiest materials on the planet. When properly installed and maintained, a Gunite pool will last a lot longer than other materials.


  • More Expensive– Gunite pools require professional installation and run on average between $15,000 and $40,000 with prices going up depending on size, depth, and shape.
  • Installation Time– A properly installed Gunite pool takes about 8-12 weeks to complete. During this time, be prepared for your yard to be a disaster area until the installer is done and cleaned up.
  • Concrete Maintenance– Gunite pools are made of concrete and can withstand a lot of pressure, but in the event of a leak, you’ll need to drain the pool and fix the crack before you can continue swimming in it.
