What Defines a Plunge Pool and How Does It Work?
Small. Deep. Built for relaxation, cooling off, and light exercise—not laps, not big gatherings, just pure, efficient use of space. A plunge pool gives you the luxury of a pool without the hassle of a full-sized one.
Here’s what matters:
- Size – Compact. 4 to 7 metres long, 2 to 3 metres wide. Perfect for small backyards.
- Depth – 1.2 to 2.4 metres. Deep enough for full-body immersion, shallow enough to be safe.
- Materials – Fibreglass, concrete, or acrylic—each with its own durability, cost, and aesthetic appeal.
- Installation –In-ground, above-ground, or pre-built. Custom or ready-to-go.
- Features – Hydrotherapy jets, heating, built-in seating, LED lighting. Make it a spa, a statement, or both.

What Are the Downsides of a Plunge Pool?
Plunge pools are efficient, stylish, and low-maintenance, but they’re not for everyone. If you’re expecting a lap pool, a party space, or a dive-friendly deep end, think again. Here’s what you need to consider:
1. Limited Space & Functionality
- Plunge pools are smaller than traditional pools, making them unsuitable for lap swimming unless equipped with resistance jets.
- Not ideal for big gatherings. Limited space means fewer people can enjoy it at once.
- No diving, no water games. The depth is designed for soaking, not high-energy activities.
2. Unexpected Installation Costs
- Excavation and groundwork can still add up, especially on tricky terrain.
- Permits and council approvals may be required, depending on location.
- Upgrades cost money. Heating, jets, and filtration systems aren’t free.
From Our Experience: One of our clients in Merewether needed additional drainage work due to a sloped yard, which increased installation time by a week. This is a common issue in hilly suburbs around Newcastle.
3. Heating Costs for Year-Round Use
- Cold water isn’t for everyone. Heating is optional but often necessary.
- Electric and gas heating add to your energy bill.
- Insulation and covers help, but they’re another upfront expense.
4. Safety Considerations
- Deep water + kids = potential risk. Fencing and safety covers are a must.
- Slippery surfaces increase the chance of falls.
- Compliance with local regulations may require extra investment.
Plunge pools aren’t for fitness swimmers, large families, or those wanting a full-sized pool experience. They’re for homeowners who want to maximise their outdoor space with a relaxing, efficient, and stylish water feature—without the bulk and maintenance of a traditional pool.
How Do Plunge Pools Compare to Hot Tubs, Swim Spas, and Lap Pools?
Plunge pools are small, efficient, and built for relaxation—but they’re not the only best option. Depending on your needs, a hot tub, swim spa, or lap pool might be a better fit. Here’s how they stack up:
Comparison Table: Plunge Pools vs. Other Pool Alternatives
| Feature | Plunge Pool | Hot Tub | Swim Spa | Lap Pool |
|---|---|---|---|---|
| Size | Small (4-7m) | Very small (2-3m) | Medium (4-6m) | Large (10m+) |
| Purpose | Relaxation, cooling off, light exercise | Relaxation, hydrotherapy | Swimming, exercise, relaxation | Fitness and lap swimming |
| Maintenance | Low | Low | Medium | High |
| Installation | Quick (1-8 weeks) | Fast (1-2 days) | Moderate (2-4 weeks) | Long (4-12 weeks) |
| Space Needed | Small | Very small | Medium | Large |
| Swim Capability | Limited (with jets) | No | Yes | Yes |
| Year-Round Use | Yes (if heated) | Yes | Yes | Depends on heating |
| Water Depth | 1.2-2.4m | 1m | 1.2-1.5m | 1.2-2m |
| Best for | Small backyards, relaxation | Relaxation, hydrotherapy | Swimming, therapy, fitness | Fitness, lap swimming |
Who Should Get a Plunge Pool and Who Shouldn’t?
A plunge pool isn’t for everyone. It’s built for relaxation, not laps. It saves space, costs less than a full-sized pool, and requires minimal upkeep. But if you’re after a traditional swimming experience, you might need something bigger.
Who Benefits Most?
A plunge pool is a smart choice if you:
- Have limited space. Small backyards, courtyards, tight outdoor areas—it fits where others won’t.
- Want low maintenance. Less water, fewer chemicals, minimal cleaning.
- Prioritise relaxation. Hydrotherapy, stress relief, and cooling off—all in one.
- Need a cost-effective option. A fraction of the price of a full-sized pool.
- Want year-round use. Heat it up in winter, cool off in summer.
Who Might Need an Alternative?
Skip the plunge pool if you:
- Need a pool for exercise. No laps unless you install resistance jets.
- Host big gatherings. Small size means limited guest capacity.
- Have young children. Depth can be a safety risk without proper precautions.
- Want a traditional swimming experience. No diving, no water games, no sprawling swim space.
If a plunge pool doesn’t match your needs, consider a swim spa, lap pool, or traditional pool instead.

Book a 15-Minute Call ➔Understanding Local Council Approval for Plunge Pools
Installing a plunge pool isn’t just about choosing the right size or shape—it’s also about navigating the rules that govern where and how it can be placed. In Australia, local council regulations are not mere bureaucratic formalities. They are essential design constraints, embedded with the intent to protect people, property, and the environment.
In Newcastle, for example, the approval process is guided by the NSW Swimming Pools Act 1992 and Swimming Pools Regulation 2018. These rules are not arbitrary—they are the product of decades of design failures, safety incidents, and environmental considerations.
Why Approval Matters
It’s easy to think of a plunge pool as a simple backyard addition. But from a regulatory perspective, it’s a structure with serious implications: it holds a large volume of water, poses a drowning risk, alters stormwater flow, and changes land use. The council’s approval process ensures that:
- Setback rules are observed—your pool must sit a certain distance from property boundaries and structures.
- Fencing requirements meet safety codes—childproof, climb-resistant, and properly gated. This regulation outlines the requirements for pool safety, including fencing standards, barrier specifications, and compliance procedures. It’s essential for homeowners and builders in Newcastle and across New South Wales to familiarize themselves with these regulations to ensure their plunge pools meet all legal safety standards
- Drainage and water runoff are managed to avoid flooding or erosion on adjacent properties.
This is more than compliance—it’s responsible design.
The Newcastle Approval Process in Practice
- Planning Approval: Some plunge pools are exempt from planning approval under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. But only if they meet specific criteria—distance from boundaries, location relative to sewers and easements, and so on. Otherwise, a Development Application (DA) is required.
- Building Approval (Construction Certificate): Whether exempt or not, you’ll likely need a Construction Certificate from a private certifier or the council. This covers structural safety and environmental management.
- Final Inspection & Compliance Certificate: Once installed, your plunge pool must be inspected and certified as compliant. This includes fencing, gate latching, and CPR signage.
What Most Homeowners Get Wrong
Most non-compliance issues don’t arise from rogue builders—they arise from assumptions. Homeowners often assume that a smaller pool means fewer rules. In fact, councils view plunge pools through the same safety lens as full-sized ones.
A Better Approach
Think of council approval not as a hurdle, but as part of the user-centred design process. The rules reflect learned lessons—sometimes painful ones—about what works and what doesn’t in real-world conditions. When approached early and thoughtfully, the approval process can actually improve your design: better drainage, safer access, smarter use of space.
Conclusion
There you have it—the real pros and cons of owning a plunge pool. Less maintenance, less cost, less space—but still all the benefits of having your own private water retreat.
