The moment when you and your family decide to invest in an in-ground pool is exciting for everyone. A pool is so much more than a place to simply cool off. It’s also perfect for entertaining, serving as a much-needed oasis away from the hustle and bustle of life, or just bringing loved ones together for some conversation and an afternoon swim. This is why it is so important to select the right pool installation for your home and your budget.

When it comes to in-ground pools, the three most common styles are vinyl-lined, concrete (often called Gunite) and fiberglass. All three have their pros and cons so before making your final decision, it’s essential to understand the basic structure and installation process for each.

Vinyl Pools: A vinyl-lined pool is structurally similar to an above-ground pool, but is installed beneath the ground. This style is made using a custom sheet of vinyl, which is installed between the water and the pool structure. A track system is used to hold the liner in place while it covers the sand or cement floor. The walls are typically constructed using galvanized steel or thermoplastic.


  • Lower initial cost when compared to other pool installations.
  • Design flexibility with it comes to colors and patterns of the liner.


  • Liner replacement can cost upwards of 4-6K (however, some liners can last anywhere from 10 to 20 years).
  • Decline in aesthetic allure as the liner fades over time, especially with chlorine pools.

Gunite Pools: A Gunite pool is one of the most popular pool installations because it is durable and also offers a lot of design flexibility. Since this type of in-ground pool uses a rebar framework, which is overlaid with a sand and concrete mixture, the homeowner can select whatever shape suits their yard.


  • Highly durable and built to last.
  • Built and installed at your home, which makes the design possibilities endless.
  • Available in an array of finishes to match decking or an outdoor living space.
  • Great selling point when and if the time comes to put your home on the market.


  • Installation time can be long so it’s important to plan ahead.
  • Maintenance costs are higher compared to other pool installations.

Fiberglass Pool: A fiberglass pool is constructed completely offsite and installed as one piece upon arrival. Like a Gunite pool, fiberglass installations are also durable since the material uses a reinforced plastic composed of glass fibers embedded in a resin matrix.


  • Easy and fast installation.
  • Require fewer chemicals due to its plastic construction.


  • Initial installation costs are much higher when compared to vinyl-lined or Gunite pools.
  • Width and depth restrictions since the pool is constructed off-site.
  • Limited shapes and finishes.

Whatever pool installation you ultimately choose, it is important to understand each style and what it has to offer. Consulting a trustworthy pool contractor for advice and guidance is a great first step. To learn more about Shoreline Pools services and designs, visit Our Services.
