1. DIY Stock Tank Plunge Pools ($3,795–$6,000)
The most budget-friendly option is the Stock Tank Pools Australia range. Their galvanized steel plunge pools start at around $3,795 and can be installed yourself over a weekend. You'll need to add things like a pump, filter, and decking if you want a more polished finish, but it's easily the cheapest way to get a durable, great-looking pool that will actually last.
2. Corrugated Steel Plunge Pools ($13,000–$18,000)
The Outback Plunge Pools and Designer Plunge Pools are made from high-grade corrugated 316 stainless steel or COLORBOND® and lined with a commercial-grade vinyl liner. These pools offer increased height and durability compared to stock tanks, making them a popular choice for those seeking a more permanent and aesthetically pleasing solution.
Outback Plunge Pools: Prices range from approximately $13,000 for the smallest 2.2m (4,000L) pool to around $18,000 for the largest 3.4m (13,000L) pool. These prices include the completed pool but exclude delivery, site preparation, and permit costs. outback.com.au
Designer Plunge Pools: Their pricing varies based on size and customization options. For detailed pricing, it's best to consult their pricing guide or contact them directly.
3. Precast Concrete Plunge Pools ($12,000–$28,000)
These are the next step up. They come ready-made and can be craned into your backyard. The benefit is speed, since they can be installed in a few days instead of weeks. Expect to pay on the lower end for smaller fiberglass models, and closer to $25,000–$28,000 for something precast in concrete like the Plungie Studio or Max models. You’ll also need to factor in delivery, site preparation, and crane hire.
4. Fully Installed Concrete Plunge Pools ($35,000–$68,000)
Custom concrete plunge pools are the premium option. They’re built from scratch on-site and can be finished with tiles, plaster, or render to suit your space. They’re the most expensive but also the most flexible. You can choose your exact shape, depth, and finish. These are what you’ll typically see in high-end architectural homes or design-focused builds.

Which Option Is Best?
If you want a simple, affordable way to cool off, the DIY stock tank from Stock Tank Pools Australia is unbeatable value. Their Family Plunge model comfortably fits a few adults, looks great with timber cladding, and costs a fraction of the price of a traditional pool.
If you're looking for a more polished look and can spend more, the Outback or Designer Plunge Pools offer a higher-quality finish and increased durability. These are great options if you're aiming for a more permanent and aesthetically pleasing addition to your backyard.
For high-end builds, the Plungie Arena (around $30,000–$40,000 before installation) is a great option that's fast to set up and built to last.
