Unlike a traditional rectangular pool, freeform swimming pools are irregular in shape and no fixed rules as to their dimensions or proportions.

A swimming pool inspired by nature

Fluid in their design, freeform swimming pools are inspired by nature. While some blend the naturalistic feel with a contemporary look by surrounding the pool with paving, others opt for a lagoon style aesthetic. In this case, the pools often incorporate rocks, waterfall features and even planting to resemble a natural waterhole, pond or lake.

Freeform swimming pools can be constructed of vinyl, fibreglass or concrete. More often than not, they are built from concrete with a process similar to that of a geometrically shaped pool. The shape is marked out on the site, the ground excavated and the framework is constructed before the concrete is poured.

The benefits of a freeform swimming pool

Freeform swimming pools can be a great option for a tricky site or to create a naturalistic feel

While freeform swimming pools aren’t as popular as a modern rectangular design, they do come with their benefits, including:


As freeform swimming pools don’t need to conform to any particular proportions they offer flexibility. This is particularly beneficial for those who have a tricky shaped backyard or a small space as you can decide on the best shape for your block.


Freeform swimming pools can add a degree of softness in a boxy space or one dominated by straight lines. The juxtaposition between the straight and curved lines can help provide visual relief.


A more curvaceous style swimming pool may better suit a rural property or one with a wilderness-like landscape than a modern geometric design. This may allow the pool to blend in more effectively into the site.


The fluid design of a freeform swimming pool creates natural indentations which provide you with the flexibility to blend in poolside seating, a shallow beach area, a spa, waterfalls or landscaping.

How to choose the right shape for your pool

Still undecided if a freeform swimming pool is right for you? Here are a few tips to help you decide what is the right shape for your pool.

1. Analyse your site

Assess the size of your site and its relationship with your house. Take a copy of your plan and draw a few different options to see what fits the space best. Let your imagination go wild and don’t feel confined to any particular form.

2. Establish your budget

Natural swimming pools can be more expensive than a simple rectangular design as the process of framing and finishing is typically more involved.

3. Determine your needs

Decide what you want from a swimming pool. Is it for leisure or do you want to use it for laps? A freeform swimming pool is ideal for relaxation and play but doesn’t function so well for swimming for exercise.

4. Consult an expert

It’s good to do your homework, but one of the best ways to establish whether your chosen swimming pool shape will work in your space is by consulting with an expert. They’ll help determine the right dimensions and proportions as well as choose the appropriate finishes and add-ons for your pool.
