A Slimline Plunge Pool Built for Small Backyards
Looking for a plunge pool that fits a narrow block without compromising on style or function? The Billabong Plunge Slimline is a slimline fibreglass plunge pool purpose-built for small backyards, courtyards and tight outdoor living areas. It’s the answer for Australian homeowners who want a swim-and-relax pool experience but don’t have the space for a full-sized backyard pool.
Rather than squeezing a standard pool into a small yard, the Billabong Plunge Slimline is engineered from the ground up as a narrow plunge pool design — proving that compact backyard pools don’t need to feel like a compromise.
Why Choose a Slimline Plunge Pool?
Small yards, courtyard homes and high-density blocks are becoming the norm across Australian suburbs — and traditional pool shapes simply don’t fit. The Billabong Plunge Slimline solves this with a narrow, elongated footprint that slots neatly along fence lines, side yards and alfresco zones, delivering the cooling, relaxation and lifestyle benefits of a plunge pool in spaces where a conventional pool never could.
If you have a little more room to play with, it’s worth comparing this range against Barrier Reef Pools’ broader plunge and slimline options:
- The non-slimline Billabong Plunge range, for extra swimming width
- The Billabong Slimline range, for a longer narrow pool with more layout options
The original Billabong pool range, for larger backyards
Smart Design Features for Compact Outdoor Spaces
Every element of the Billabong Plunge Slimline has been considered to make the most of a narrow footprint, without sacrificing comfort or usability.
- Slimline Plunge Design — A streamlined, space-efficient shape purpose-built for courtyards, terraces and small backyard pools
- Lengthwise Bench Seating — A full-length seated relaxation zone running alongside the pool and entry area, with the option to add spa jets for a resort-style upgrade
- Flat 1.6m Depth — Deep enough for light exercise and active use, while still comfortable for relaxed soaking
- Compact Footprint — Purpose-built for smaller, higher-density blocks where space is at a premium
The result is a small plunge pool that still delivers the depth, seating and everyday usability of a much larger pool.
Plunge Pool Sizes and Installation Options
The Billabong Plunge Slimline is available in two sizes, so you can choose the best fit for your available space:
| Length | Width | Flat Bottom |
| 4.20m | 2.60m | 1.60m |
| 4.20m | 1.60m | 1.60m |
Dimensions are in metres, external and approximate. Pool coping is 100mm. The 4.2m x 1.6m size does not include a side seat.
Each size is available as either an in-ground pool or an above-ground pool, giving you the flexibility to install on flat blocks, sloping sites or otherwise tricky terrain — making it one of the more adaptable plunge pool ranges for challenging backyards.
Add a Spa for a Resort-Style Backyard
Want to take your small backyard pool to the next level? Pair your Billabong Plunge Slimline with one of Barrier Reef Pools’ square spa designs. Integrated overflow openings create a cascading water effect from the spa into the pool (or an adjoining water feature), turning a compact backyard into a private day-spa retreat.
