Round Above Ground Pools

Round above ground pools are the most popular choice for Massachusetts homeowners — and for good reason. They're affordable, easy to install, and offer the most swimming area per dollar of any pool shape. At Aquarian Pool & Spa, we carry a range of round above ground pools in sizes from 12 to 33 feet in diameter.

Round pools are structurally simpler than oval pools because the water pressure is distributed evenly around the entire circumference. This means no support braces are needed, making installation faster and less expensive. The circular shape also allows for excellent water circulation with a single return jet.

Whether you're looking for a small pool for the kids or a large pool for the whole family, round above ground pools offer great value and versatility.

Advantages of Round Above Ground Pools

More Affordable

Round pools cost less per square foot of swimming area than oval pools, and installation is simpler.

Better Water Circulation

The circular shape allows water to circulate naturally, keeping the pool cleaner with less effort.

No Support Braces

Unlike oval pools, round pools don't need buttress systems, reducing cost and complexity.

Easier Installation

Simpler assembly means faster installation — often completed in a single day.

Structural Strength

Even water pressure distribution makes round pools inherently strong and durable.

Choosing the Right Round Pool Size

Choosing the right pool size depends on several factors:

  • Yard space: Measure your available area, accounting for setbacks and equipment access.
  • Family size: Allow about 15 square feet of surface area per person.
  • Budget: Larger pools cost more for the pool itself, more water, more chemicals, and a larger filter system.
  • Usage: Think about how you'll use the pool — relaxing, exercising, kids playing, or entertaining.
  • Wall height: Pools come in 48", 52", and 54" wall heights — taller walls mean deeper water.
