How Small Can a Fiberglass Pool Be?

If you’re in the market for a new pool, you should become acquainted with all of your possibilities. Fiberglass pools are a popular alternative to concrete and vinyl liners these days because they provide several distinct advantages.

But exactly what are fiberglass pools? What distinguishes them from other styles? Here’s what you should know:


What Exactly Is A Fiberglass Pool?

A fiberglass pool is constructed with a reinforced fiberglass shell that is covered in protective gel coatings. The shell is built off-site and erected in a single piece.

What Distinguishes Fiberglass Pools From Other Types Of In-Ground Pools?

Fiberglass pools have a one-piece fiberglass shell and, unlike vinyl pools, no liner that needs to be replaced every few years.

They are also different from concrete pools, which are made by pouring concrete over steel rods to make the pool’s shell, which is then finished with other materials like plaster.

Why Should You Consider Fiberglass Pools?

Some of the distinct advantages of fiberglass pools are as follows: 

1. Simple installation 

Fiberglass pools are easy to build because they are built in one piece. Once the shell has been built, it can usually be placed in a matter of days. Installing a vinyl pool can take many weeks. If you want a bespoke concrete pool, you’ll have to wait a few months for it to be completed.

2. Maintenance-free 

Because fiberglass is incredibly durable and non-porous, it is considered almost maintenance-free. Concrete pools, on the other hand, are extremely porous and require significantly more upkeep to keep them clean and attractive. In addition, unlike vinyl pools, fiberglass pools do not have a liner. 

3. Durability 

When using a vinyl pool, be careful not to puncture the liner. Fiberglass pools are far more durable and less prone to damage. 

4. Lower long-term ownership costs

While fiberglass pools have a greater initial cost than vinyl liners, they cost much less in the long run due to the low maintenance required.

Why Should I Not Desire Fiberglass?

As previously said, fiberglass pools have a greater initial installation cost, but they will cost less to maintain over the life of the pool.

Furthermore, if you want a custom-shaped pool, fiberglass may not be the best option because the shells are not changeable. You can, however, select from a variety of styles and shapes.

What Are The Largest And Smallest Fiberglass Pool Sizes?

Fiberglass pools are typically 20 feet long by 10 feet wide, while they can be found as short as 15 feet long and 8 feet wide.

They can also grow to be up to 16 feet long and 40 feet wide, but not much larger. They are brought by highway to your backyard and must adhere to the size regulations.

Most manufacturers, for example, produce shell sizes in the 10’x20′ range. So, whether it’s a kidney, rectangle, roman, or free-form design, the industry has lots of small sizes. 

However, when it comes to pool sizes, keep in mind that size does not always determine play area. Diving pools, for example, may be large, but they do not make good play pools because there is only around 13′ of the play area and the rest is either a hard slope or a diving well area. 

 Also, while steps, benches, and seats are fantastic for relaxing, they limit the amount of play area within the pool.

When you enter, you dive immediately into the “deep” end. This deep end, though, isn’t very deep; it’s approximately shoulder height.

Is it safe to work out in my tiny fiberglass pool? 

While simply relaxing in the pool is enjoyable, many people desire a swimming pool to work out. Small fiberglass pools are designed to be used for exercise even if you have limited pool space.

A plunge pool’s continuous depth makes it perfect for low-impact aerobics or even underwater fitness equipment. The buoyancy of the water relieves pressure on your muscles and joints, making it ideal for those suffering from arthritis or fibromyalgia. Water resistance, on the other hand, contributes to a wonderful exercise.

Of course, you can do a similar workout in a tiny swimming pool. So, if you want a swimming pool that can support various types of exercise, a small fiberglass pool is ideal.
