In-Ground Concrete vs Fiberglass Pools: A Comprehensive Comparison

When it comes to choosing the perfect pool for your backyard, two common options for swimming pool construction come into play: in-ground concrete and fiberglass pools. Deciding which shell you’d like to boast your backyard with is not a seamless decision, especially without the knowledge of an expert.

In this article, we will go into the details of each type of pool—covering their pros and cons as well as providing a simple checklist for choosing between the two.

What’s The Difference?

The main difference between in-ground concrete and fiberglass pools lies in their construction material. Concrete pools are tailor-built during swimming pool construction by pouring concrete into a customized hole or structure and are typically finished with plaster or tile. This type of pool can be shaped and sized according to your preferences.

Fiberglass pools, on the other hand, are made from fiberglass-reinforced plastic that is molded into a preset shape and size and installed as a whole unit into the ground. While they may not have as many design options as concrete pools, they come in a variety of shapes and sizes to suit different needs.

In-Ground Concrete Pools

In-ground concrete pools have been around for centuries and are the most traditional type of pool. Their swimming pool construction involves digging a large hole in the ground and then lining it with concrete. Here are some key points to consider when deciding if an in-ground concrete pool is right for you:


  • Customization: Concrete pools can be designed and shaped according to your preferences, making them a great option for unique or difficult backyard layouts.
  • Durability: Unlike fiberglass pools, which have a lifespan of around 15-30 years, concrete pools can last for decades with proper maintenance.
  • Aesthetics: With the ability to add custom tiles, finishes, and features, in-ground concrete pools offer endless design possibilities.


  • Cost: Due to their complex and sometimes lengthy construction process, in-ground concrete pools tend to be more expensive than fiberglass pools.

Fiberglass Pools

Fiberglass pools are a relatively newer addition to the pool industry. They are pre-made shells that arrive at your home ready to be installed in the ground. Let’s take a closer look at the advantages and disadvantages of choosing a fiberglass pool:


  • Quick Installation: Fiberglass pools are pre-made and simply need to be placed into the ground, making the process quicker than traditional swimming pool construction.
  • Smooth Surface: The smooth surface of fiberglass makes for easier cleaning and maintenance, and provides a gentle feel on skin and swimsuits.
  • Cost-Effective: The initial cost may be lower for a fiberglass pool and its low maintenance and repair costs could save you some money in the long run.


  • Limited Design Options: As they are pre-made, fiberglass pools have limited design options and cannot be customized to the degree concrete pools can.
  • Less Durable: Fiberglass is prone to cracking or bulging due to ground movement, making it a less durable option than concrete pools and potentially costing you more money in the long run for fiberglass repairs.

How to Choose Between Concrete and Fiberglass Pools

If you’re still unsure about which type of pool is right for you, here is a simple checklist to help guide your decision-making process:

  1. Consider Your Budget: If cost is a major factor, fiberglass pools may be the more affordable option in terms of long-term maintenance—but remember that concrete lasts longer.
  2. Installation Time: If you want your pool up and running quickly, fiberglass is the way to go since the construction process can be faster. The typical turnaround time for a fiberglass pool is 3-4 weeks compared to an inground concrete pool spanning around 6-8 weeks.
  3. Customizability: If customizing your pool is important to you, then an in-ground concrete pool may be the way to go.
