A large backyard may seem like a requirement for an backyard pool, but it’s not the only way to create a functional outdoor space. With the right design, even smaller yards can accommodate a pool that fits your lifestyle.
Small fiberglass pools have become a popular option for homeowners who want the experience of a backyard pool, without needing a huge space to make it happen.
If you're working with a smaller yard (or just don’t want something oversized), a smaller pool might be exactly what you’re looking for.
So what are your options, and what should you expect?
What is considered a small fiberglass pool?
In most cases, small fiberglass pools are up to about 26 feet long and 12–13 feet wide.
That might sound small, but these are still fully functional pools. You can swim, relax, entertain, and enjoy all the same features, just in a more space-efficient layout.
You may also come across smaller designs like plunge pools or cocktail pools. These are built more for cooling off and relaxing, making them a great fit for compact backyards.
What shapes work best for small fiberglass pools?
Should your small pool have a linear or freeform style? Depends on your goals.
Linear pools (think rectangles and clean lines) are more structured. If you’re working with limited space and want to make the most of every inch, this style usually gives you more usable swim room.
Freeform pools are all about curves. They feel a little more relaxed and natural, like the pool version of that cozy, slightly oversized sweater you never want to take off. They also tend to blend nicely with landscaping and can soften up a tighter space.
So which one’s better? It depends not just on your style, but also on the space you’re working with.
Some backyards are long and narrow, others are wider or have angles and landscaping to work around. A linear pool can make the most of a tighter, more structured space, while a freeform design can help soften awkward corners or create a more natural flow.
In other words, it’s not just about what you like—it’s also about what fits your yard best.
How much do small fiberglass pools cost?
The cost of small fiberglass pools can vary quite a bit depending on your location, installation needs, and features, but here are general ranges:
- Base packages: roughly $85,000–$135,000
- Turnkey projects: typically $85,000–$200,000+
Smaller pools are usually less expensive than larger ones, but not always by as much as people expect. A lot of costs, like excavation, equipment, and labor, are similar regardless of size.
Still, going smaller can free up budget for things like water features, heating, or patio upgrades.
Pros of small fiberglass pools
Small fiberglass pools come with a few built-in advantages, especially when space and simplicity are top priorities.
More social by design
With less space to spread out, it’s easier for everyone to stay connected, whether you're relaxing, chatting, or just hanging out in the water.
Easier to maintain
You still need to maintain the pool regularly, but less water and surface area equals less to clean, treat, and keep up with.
More budget flexibility
While not drastically cheaper, a smaller pool can free up room in your budget for upgrades like heating, lighting, or water features.
Fits smaller backyards
For tighter spaces, a small fiberglass pool can turn a “maybe not” into a “why not?” and make a pool possible where it otherwise wouldn’t be.
Cons of small fiberglass pools
Of course, going smaller isn’t perfect for every situation. Here are a few limitations to keep in mind:
Limited swim space
If you’re planning to swim laps regularly, a smaller pool may feel restrictive without added features like swim jets.
Shallower depth
Because there isn't enough length for a serious deep end, most small pools run relatively shallow, which is great for relaxing and family use, but less ideal if you’re looking for deeper water.
For example, the 24-ft. model in our D Series is about 5'3" deep, and our 20-ft. R Series model is about 4'4" deep. Compare that to their 40-ft. siblings, which are about 6'6" deep.
Less room to spread out
When you have a full group over, things can feel a bit more crowded compared to a larger pool.
Final thoughts on small fiberglass pools
Small fiberglass pools aren’t about getting less, they’re about using your space differently.
In the right backyard, they can feel just as functional and enjoyable as a larger pool, while being easier to maintain and more flexible in design.
The key is understanding what you want out of your pool and choosing a size and shape that supports that, not just what looks good on paper.
