Fiberglass pools are extremely easy to maintain, can be installed quickly, are very durable, and can be beautifully designed. However, their initial cost can be higher than vinyl liner pools, and the shapes and sizes are not as customizable.
The cons associated with fiberglass pools are primarily related to cost and installation issues. Contrary to popular belief, fiberglass pools aren't cheaper than traditional options like concrete (we'll provide more details in the “Costs” section later on).
Fiberglass is considerably stronger than concrete and will not require re-plastering or acid washes over time. Fiberglass has a smooth, non-porous surface that is very easy to clean and maintain. Fiberglass is an insulator that, coupled with an autocover, can help owners save big on heating costs and maintenance.
Some of the most common include that this pool type floats or pops up, that they look cheap, that they only work in warm climates, that they are are lot more expensive than vinyl liner pools, and that they cannot be customized. Unfortunately, many people shy away from fiberglass pools because they believe these myths.
Most fiberglass pools are known to last 25-30 years, but we take that to the next level. Our manufacturer, Narellan Pools, makes the best fiberglass pools around. Their unique fiberglass formula results in a pool that can last as long as 50 years! Plus, these pools are notoriously easy to maintain.
While they are easier to install, fiberglass pools are nowhere near as durable as a gunite inground pool. The inside surface of this type pool is a gel coat on which the fiberglass has been laminated. The walls of the pool are only ½ to ⅜ inch thick compared to the 8 to 10 inch thickness of a gunite pool.
Luckily, heating is not only an option for fiberglass pools, it's actually a wonderful idea for them. Fiberglass pools are both the easiest type of pool to heat and the least expensive.
Fiberglass pools can craze or check crack from imprecise manufacturing or when the surface is not fully supported, like under the steps or areas where the backfill is eroded. Gelcoat can also crack during transport and installation if it gets bumped around too much.
In contrast, fiberglass tends to be smooth to the touch. The flip side of that is that it can get slippery, a particular concern for pool steps where falls can happen. However, a slippery surface isn't necessarily a flaw in the pool shell, but an indication that there's an algae problem.
Data numbers are based on sales in areas requiring pool permits, which necessarily excludes large market regions where permits are not required — there is ample evidence of a surge in fiberglass popularity.
One of the biggest gripes that we see have to do with the slippery surface of a fiberglass pool. The fact is, this material can be so slick that pool users can actually slip and fall. This can be a real problem for pool steps, where a slip-and-fall accident can be dangerous.
Fiberglass pools are exceptionally durable and can last the lifetime of a home. Vinyl liner pools can also last the lifetime of a home. However, the liner itself will need to be replaced on average every ten years, but provides a unique opportunity to completely refresh the look of your pool.
Fiberglass pools that are 27' to 35' long have depths which range from 3 ½' to 6 ½'. Fiberglass pools that are 35' to 40'+ long the depths can go anywhere from 3 ½' to 8' deep.
Inhaled slivers of fiberglass irritate the alveoli and can cause lung disease. There is some data which suggests fiberglass in the lungs may cause cancer, by slicing DNA and causing cell mutation, in the same way as mineral wool. Some fiberglass still uses formaldehyde as a binder, which leaks out into the air.
Inground swimming pool LED lights will add a truly breathtaking nighttime appeal to your pool. Providing a luminous setting for impromptu get-togethers and evening swims, inground pool LED lights impart an enchanting ambiance to any style of pool.
Many people wonder if their fiberglass pools are strong enough to withstand the extremes of winter weather. The answer is a resounding “Yes!” Cold temperatures are not a problem for fiberglass pools, so long as you properly care for them.
Dogs almost never damage fiberglass and concrete pools, but their claws can puncture a vinyl liner. They need big steps, and a tanning ledge is best.
Cheap materials
Fiberglass pools that are made cheaply are… cheap. Thin side walls can cause unsightly bulges. Low-quality gelcoats can scratch and crack more easily.
The gelcoat surface of a fiberglass pool is smooth and nonporous, leaving little room for unwanted guests like algae. Because of that, it requires less brushing and less overall work. If algae does rear its irritating little head, just shock the pool with the SLAM method.
While there are many myths about fiberglass pools, the one thing you should NEVER EVER do is DRAIN your fiberglass pool without professional help. Let me say that again, NEVER drain your fiberglass pool for any reason. In fact, we recommend NEVER letting the water level drop more than 2-3 inches below the skimmer!
Fiberglass swimming pools are very compatible with salt water systems. If you are using a vinyl liner pool, you must be careful as those pools tend to have metal parts or connections which salt will eat through and corrode.
Fiberglass swimming pools were designed to be affordable, attractive, safe and easy to maintain. Polished concrete makes the perfect surrounds for fiberglass swimming pools, because it shares these same characteristics.
A fiberglass pool is not prone to growing algae, which is one of the main reasons why this pool is easier to maintain. Anyone who is looking for a pool that doesn't require a lot of maintenance may want to consider going with a fiberglass pool.
Lower cost – depending on your preference for shape and size, fiberglass pools inclusive of equipment can range from $55k-$70k. This is often a lower cost option compared with a custom gunite pool.
