FIberglass Pools and Spa 101


So, you want to get a fiberglass pool but are confronted with the dilemma of which design you like best.
We get that.
As fiberglass pool manufacturers, we see many people get stuck on which pool model they want to install, and it’s not hard to see why.
Each fiberglass pool model has a unique shape and set of features that you won’t find anywhere else. Fiberglass pools can also last 50 or more years and become a permanent part of your home.
If you’re not sure which pool design will work for you, this article can help you learn more about your options and explore some of the pros and cons of the different fiberglass pool design features.
Let’s quickly dive into fiberglass pool shapes and sizes, and then we’ll cover popular features and installation options.

Fiberglass Pool Shapes and Sizes 
To give you a brief overview, fiberglass pool models typically range from around 10 by 20 feet to 16 by 40 feet. You can find fiberglass pool models smaller than 10 by 20 feet, but the majority will be around this size or larger. Because of shipping limitations, you’ll also find that fiberglass pool models aren’t typically wider than 16 feet or longer than 40 feet.
As far as pool shapes go, you’ll have a wide range of options across all fiberglass pool manufacturers, but swimming pool shapes fall into two main categories:

  • Rectangle
  • Freeform

Each pool shape comes with its pros and cons, and you’ll find that there’s much more to choosing a pool shape than aesthetics alone.
For example, freeform pools have a lot of character, but they don’t always work with automatic pool covers. Rectangle Pools are compatible with most if not all pool covers types, but some shoppers may find the design to be a little too plain.
Now that we’ve covered the basics of shapes and sizes, let’s get into some of the features that you may find on a fiberglass pool model.

Fiberglass Pool with Tanning Ledge (Built-In) Pros and Cons

  • More lounging space
  • Good for in-pool furniture
  • Good for children and pets


  • Sacrifices some swim space

Fiberglass Pool with Spa
Are you looking for a pool and spa combo? You’ll also find many fiberglass pool models with the spa built into the design. This is a great way to save space for those who want a pool and spa but have very small backyards.
Like with tanning ledges, many fiberglass pool manufacturers offer seperate spas that can be added to the side of any fiberglass pool installation.

Fiberglass Pool with Spa (Built-In) Pros and Cons 

  • Saves space
  • Looks nice


  • Sacrifices some swim space
  • Requires additional maintenance

Fiberglass Pool with Seats
Let’s face it – swimming is a workout. Even casually floating or paddling around for an hour can be tiring. Most fiberglass pools come with some type of seating (not the pool steps), offering a place to rest and relax for one or more swimmers. This means that your kids can sit comfortably between games instead of hanging on to the sides of the pool.

 You can also install bubble inside your pool on steps and tanning ledges. A pool bubbler is a small fountain of bubbling water that can be placed in any shallow area of the pool surface.


What’s the Best Fiberglass Pool Design for You?

If you’ve read the entire article and still aren’t sure which fiberglass pool design is best for your home, you can answer the following questions to help clarify your wants and needs.

  1. Do you like the look of a tanning ledge, or do you want in-pool furniture?

If you answered “yes”, then you might want to consider a model with a tanning ledge or you can talk to your pool builder about adding a separate one to your project.


  1. Would you like to have a spa as well? Do you have additional space for a spa?

If you answered “yes” to both questions, you can take your pick among all pool models with built-in spas, as well as separate spa add ons. If you would like a spa, but you don’t have the extra space, we would suggest narrowing your search to a pool with a built-in spa.


  1. Which pool do you like more?

  1. Is your yard on a slope, or do you have problems with flooding and groundwater in your area?

If you said “yes” to any of these, you might want to consider a pool with a retaining wall or even a semi-inground or fully above ground pool.
