Updated November 2026
An installed fibreglass plunge pool commonly costs about $25,000 to $55,000 in 2026, depending on its size and the site. Precast concrete shells cost about $22,000 to $27,000 before delivery and installation. Custom concrete plunge pools usually start around $50,000. Plunge pools are smaller, usually 2 to 6 m long and about 1.1 to 1.6 m deep, but they need the same approvals and barrier as a full-size pool.

These ranges come from a Queensland plunge pool installer's published 2026 prices. One Brisbane builder lists a 4 × 2.5 m fibreglass plunge pool from $47,939 installed, including excavation, crane, equipment, approvals and engineering.
Concrete plunge pools
- Precast concrete: bare shells are listed at about $22,000 (2.5 m) to $26,500 (4 × 2.5 m), with extra for glass bead or tiled finishes. Delivery, crane and installation are extra.

What is included?
Check whether the quote includes excavation and spoil removal, the crane, filtration and plumbing, electrical work, coping, approvals, engineering and fencing. Heating is often added to plunge pools so they can be used year-round. Budget about $5,000 to $10,000 for a heater, and see our pool heating guide to compare systems.
Why plunge pools are not always cheap
A plunge pool uses less material, but many costs are fixed: approvals, the crane, equipment, electrical work and the barrier. Small courtyards can also mean difficult access. As a result, a plunge pool rarely costs half as much as a full-size pool.
Approvals and fencing
Plunge pools that can hold 300 mm of water or more need approval and a compliant pool barrier. See our pool safety laws guide for the rules in your state.
