Fibreglass Pool Dimensions, Layout and Size

May 13, 2023


It can be tricky to know which pool to choose – much of your decision will depend on its dimensions, layout, and size, plus the space you have to work with and, of course, your personal preferences. But, if you follow our simple guide, it’ll be much easier than you think.

Choosing the right pool for your home comes down to deciding on four major things:

  • The best size for your backyard and budget
  • The right shape for your yard
  • Your preferred color
  • The best installer

Remember, figuring these things out can be a fun journey, and we’re here to help you along the way. This handy guide will walk you through figuring out the shape and size options. If you’d like to jump ahead, though, go ahead and browse the sizes and pricing for our range.

Common layout and size for the 3 most common pool types

When considering the layout and size of your pool, always ask yourself two things: how will you best fit a pool within your yard, and what is the best use of your space?

For example, if you love to swim laps, consider a long, thin lap pool. A plunge pool, on the other hand, comes in more shapes than other types because they’re quite a bit smaller. A standard rectangular pool will maximize or make the best use of your space. Keep reading to learn more about each type and typical sizes.

Layout or Shape

While pool sizes and shapes vary along with budget considerations, a typical home will generally have a pool that falls into one of three categories:

Regular, Rectangular Pools

Rectangular is the shape and style most of us envision when we think of a backyard swimming pool. These pools often have more than enough room to cool off, play games, entertain, and get some exercise in.

Lap Pools

As the name suggests, lap pools are designed for swimming laps! They are a long, narrow shape with minimal features so you can swim your laps unobstructed. This pool type is great for exercise but generally less family-friendly.

Plunge Pools

Plunge pools are smaller and designed for relaxing, cooling off and entertaining, rather than swimming. Flexible in shape and size, they typically have a flat bottom, sit somewhere between the size of a spa and a regular pool, and are ideal for those with limited space who still want an ideal place to escape the heat.

Round Pools

Round pools are generally the smallest of all. Closer to a spa or jacuzzi than a regular rectangular or even plunge pool. Round pools are made for sitting in rather than swimming. They have a flat bottom and feature a bench around the entire rim. These pools deliver a brilliant space to converse with friends and family while staying cool.

Frequently asked questions

Still have questions about the dimensions, layout or size options for your new fibreglass pool? Below is an overview of the most common questions we see. If we’ve missed anything, feel free to get in touch with our friendly team, we’d love to help out!

What are standard pool sizes?

A typical rectangular backyard pool in Australia is around 14m x 6m (84m2). Other popular options are lap pools (around 12m x 2.5m or 30m2) and plunge pools (around 3m x 3m or 9m2).

What is the best size pool for a family of 4 or 5?

Assuming space and budget are suitable, a larger pool like our Valentina is your best option. At 8m x 4m with a ledge along one side, this model is ideal for families with children – from toddlers learning to swim up to older kids wanting to play with their friends.

What shape of pool is best?

In most situations, a rectangular pool is your best option. This is why it’s the most common. While bespoke shapes have their place, the long, straight sides of a rectangular design generally make for a more versatile pool. Rectangular pools often fit perfectly into most yards, since a typical block is also rectangular.

The three most common pool styles in Australia are rectangular pools, lap pools and plunge pools. See the information above for more information.
