What is a fibreglass pool?

A fibreglass pool is a type of swimming pool that is pre-formed in a factory using fibreglass-reinforced plastic. These pools come in a variety of shapes and sizes and are installed into a pre-dug hole in the ground. Fiberglass pools have become popular due to their durability, low maintenance requirements, and relatively quick installation process compared to traditional concrete pools. They are also known for their smooth finish and resistance to algae growth.

What are the advantages and disadvantages of fibreglass pools?

Fiberglass pools offer several advantages and disadvantages compared to other types of swimming pools like concrete or vinyl:


  1. Quick installation: Fiberglass pools are manufactured off-site and installed as a complete unit, which can significantly reduce the installation time compared to other types of pools.
  2. Low maintenance: The smooth gel coat surface of fibreglass pools is resistant to algae growth, reducing the need for frequent cleaning and chemical treatments.
  3. Durability: Fiberglass pools are less prone to cracking and damage compared to concrete pools, which can be susceptible to cracking over time.
  4. Smooth surface: The gel coat finish of fibreglass pools provides a smooth surface that is gentle on the skin and feet, reducing the risk of abrasions.
  5. Energy efficiency: Fiberglass pools often have better insulation properties than concrete pools, which can help retain heat and reduce heating costs.


  1. Limited customization: Fiberglass pools are typically available in a range of pre-designed shapes and sizes, limiting the level of customization compared to concrete pools.
  2. Transportation limitations: Fiberglass pools are prefabricated and transported to the installation site, which may pose logistical challenges depending on the size and location of the pool.
  3. Initial cost: While fibreglass pools may have lower long-term maintenance costs, they often have a higher upfront cost compared to vinyl or concrete pools.
  4. Surface repair limitations: While fibreglass pools are durable, they can still be susceptible to surface damage, and repairs can be more challenging and expensive compared to other pool types.
  5. Limited lifespan: While fibreglass pools are durable, they may not last as long as properly maintained concrete pools, which can potentially last for decades.

Overall, the choice between fibreglass, concrete, or vinyl pools depends on factors such as budget, desired customization, and maintenance preferences.

How long do fibreglass pools last?

The lifespan of a fibreglass pool can vary depending on factors such as the quality of construction, maintenance practices, and environmental conditions. However, properly installed and maintained fibreglass pools can last for several decades.

On average, fibreglass pools are expected to last between 25 to 30 years or even longer with proper care. Regular maintenance, such as keeping the pool clean, maintaining proper chemical balance, and addressing any repairs promptly, can help extend the lifespan of the pool.

It’s essential to follow the manufacturer’s guidelines for maintenance and care to ensure the longevity of the fibreglass pool. Additionally, factors such as UV exposure, freezing temperatures, and ground movement can affect the lifespan of the pool, so proper installation and maintenance are crucial.

What can damage a fibreglass pool?

Fiberglass pools are generally durable, but several factors can potentially cause damage over time:

  1. Improper installation: Poorly installed fibreglass pools can lead to structural issues, such as bulging or cracking. It’s essential to hire experienced professionals for the installation to ensure proper placement and support.
  2. Ground movement: Shifting soil or ground movement can put pressure on the fibreglass shell, leading to cracks or structural damage. Ensuring proper soil compaction and drainage during installation can help mitigate this risk.
  3. Impact damage: Heavy objects or sharp items can cause surface scratches or punctures in the fibreglass shell. Care should be taken to avoid dropping or dragging heavy objects across the pool surface.
  4. Chemical imbalance: Improperly balanced pool water can corrode the gelcoat surface of the fibreglass shell over time. Regular testing and maintenance of water chemistry are essential to prevent damage to the pool surface.
  5. UV exposure: Prolonged exposure to sunlight can cause fading and degradation of the gel coat surface. Using a UV-resistant coating or applying a protective sealant can help mitigate UV damage.
  6. Freezing temperatures: In areas with cold climates, freezing temperatures can cause the water in the pool to expand, potentially leading to cracking or damage to the fibreglass shell. Proper winterization procedures should be followed to protect the pool during the colder months.
  7. Chemical exposure: Certain chemicals, such as strong acids or solvents, can damage the fibreglass surface if they come into contact with the pool shell. It’s essential to handle and store pool chemicals properly and avoid using harsh cleaning agents on the pool surface.

Should I change from a concrete pool to a fibreglass pool?

Whether you should change from a concrete pool to a fibreglass pool depends on various factors, including your preferences, budget, and the condition of your current pool. Here are some points to consider:

  1. Maintenance: Fiberglass pools generally require less maintenance than concrete pools due to their smooth surface, which is resistant to algae growth. If you’re looking to reduce the time and effort spent on pool maintenance, switching to a fibreglass pool could be advantageous.
  2. Durability: Fiberglass pools are known for their durability and resistance to cracking, unlike concrete pools, which can develop cracks over time. If your concrete pool is showing signs of deterioration or requires frequent repairs, switching to fibreglass could offer a more durable and long-lasting solution.
  3. Cost: The initial cost of installing a fibreglass pool may be higher than resurfacing or repairing a concrete pool. However, fibreglass pools can be more cost-effective in the long run due to lower maintenance and repair costs. Consider your budget and the overall cost of ownership when making your decision.
  4. Customization: Concrete pools offer more flexibility in terms of customization, allowing you to create a unique shape, size, and design. If you value customizability and have specific design preferences, sticking with a concrete pool may be the better option.
  5. Aesthetics: Fiberglass pools come in a variety of shapes and sizes, but they may not offer the same level of aesthetic options as concrete pools. Consider whether the design and aesthetics of a fibreglass pool align with your preferences and the overall look of your outdoor space.
  6. Installation time: Fiberglass pools are typically quicker to install compared to concrete pools, which require more time for construction and curing. If you’re looking for a faster installation process, switching to fibreglass could be beneficial.

Ultimately, the decision to switch from a concrete pool to a fibreglass pool depends on your specific needs, preferences, and circumstances. It’s essential to weigh the pros and cons carefully and consult with pool professionals to determine the best option for you.
