Fiberglass Pools

Benefits of Installing a Fiberglass Pool

  • It’s easy to clean and maintain: Fiberglass swimming pools have a gelcoat surface that makes for effortless cleaning and maintenance. Unlike concrete, the fiberglass pool surface doesn’t have large pores so it won’t develop algae or mold over time. You also won’t need a lot of chemicals or chlorine to maintain the pH levels of your fiberglass swimming pool.
  • Offers great value for money: Fiberglass swimming pools have an almost non-existent lifetime cost because they require very little upkeep.
  • Quick installation: Fiberglass pools are pre-fabricated which means they’re built and assembled on site at the factory. As a result, fiberglass pool installation can take several days to a few weeks depending on the size. This is a far cry from the amount of time required to install a concrete pool which can take months.
  • Offers different designs: Fiberglass swimming pools may be pre-fabricated but that doesn’t necessarily limit the designs you have to choose from. Most models even come with built-in seating and steps at no extra cost.
  • Has a smooth and non-abrasive surface: Thanks to the gelcoat veneer, fiberglass pools have a very smooth surface. It’s safe for kids to swim in without getting scrapes and bruises and you won’t have to worry about your swimming clothes getting snagged.
  • Beautiful design: Nowadays, fiberglass swimming pools offer some of the most beautiful designs on the market. Some have ceramic tile, gorgeous pool lights, poolside walls, tanning ledges, colored finishes and even elevated spas etc.

Drawbacks of Installing a Fiberglass Pool

  • There’s a limit to the type of shapes that you can design: There’s a limited number of fiberglass pool molds available and this doesn’t allow you to customize your pool completely. So if you’re not happy with the available molds, tough luck.
  • They can never be wider than 16 feet: Fiberglass pools are limited in size and cannot be larger than 16 feet. That’s because they’re shipped on the road and trucks can only carry so much weight.
  • They come with a higher up-front cost: Fiberglass pools demand a higher up-front cost than other models. They usually start at $10, 000 minimum.
  • Repairing them can be difficult: The colored finishes on fiberglass pools are usually unique and once-off creations. This makes it difficult and even impossible to find a matching finish when you need to repair them.

Concrete Pools

Benefits of Installing a Concrete Pool

  • There’s no limit to the size: You can make your concrete pool as big as you want, and there’s no limit to the shape or depth of the pool either.
  • They’re beautiful: You can tailor your concrete pool to match the design of your landscape perfectly and turn your backyard into a real work of art.
  • You can choose any design feature you like: You can customize your concrete pool to the tee and add features like tanning ledges, beach entries and vanishing ledges.

Drawbacks of Installing a Concrete Pool

  • Requires more chemical use when cleaning: Concrete pools have a very porous surface which makes them a breeding ground for algae and mold. The pH levels tend to get off track and alkalinity increases, requiring a constant addition of acid to keep things balanced.
  • They’re very high maintenance: With a concrete pool, it’s essential that you sweep and brush it regularly to prevent algae build-up, which is inevitable due to the porous surface.
  • They take longer to install: Concrete pools usually take about 3 to 6 months to install, during which your backyard will look like a construction site the whole time.
  • They have a higher lifetime cost: Concrete pools need a lot of ongoing renovation over the years. For example, you need to resurface it regularly which can cost $10, 000 to $20, 000 a pop or even higher. Not to mention the expense of regular cleaning to prevent algae build up.
