Can A Plunge Pool Be Above Ground?

At Plunge Pools Melbourne, we help homeowners design and build durable, beautiful above-ground plunge pools that fit perfectly with their space, style, and budget — pools that not only look incredible but last for years to come.

In this guide, we’ll show you everything you need to know about choosing an above-ground plunge pool that matches your home and lifestyle. Ready to explore your options? Let’s dive in!

What Is an Above-Ground Plunge Pool?

An above-ground plunge pool is a compact, deep pool built above the ground, requiring no excavation. It’s installed on a solid base like a concrete slab or reinforced deck, offering a faster, more affordable alternative to inground pools—perfect for small spaces and quick setup.

Make It Look Lik

• Melbourne homeowners love the convenience of installing above-ground plunge pools on challenging terrain — from tight courtyards to sloped gardens where traditional pools aren’t feasible.
• Melbourne families often choose above-ground pools because they can go from bare yard to swim-ready in just a week—perfect for enjoying the summer without waiting months.
• With no excavation or heavy machinery required, above-ground options offer a smart, cost-effective way to enjoy a pool without the $50K+ in-ground price tag.
• From timber decking to stone cladding, homeowners can elevate the look of their pool area with design touches that match their outdoor aesthetic—without breaking the budget.
• Smaller and more efficient, above-ground pools use less water, fewer chemicals, and lower energy—great for Melbourne’s eco-conscious households.

Above-Ground Plunge Pool Installation

An above-ground plunge pool is faster and easier to install than an inground plunge pool — but skip the planning, and you’ll regret it. Installing a plunge pool the right way means choosing the best location, preparing a solid foundation, and ensuring proper setup. Here’s how to do it right.

Step 1: Pick the Right Spot

• Solid Ground – Level and compact so the small plunge pool doesn’t shift.
• Good Drainage – Water should flow away from your house, not toward it.
• Sunlight – More sun = warmer water = lower heating costs.
• Easy Access – You’ll need room for maintenance and entry.
• Privacy – Unless you like putting on a show for the neighbors.

Step 2: Pick the Right Material 

Your plunge pool will be fibreglass pools, concrete, or vinyl liner. Each has pros and cons. Pick wrong, and you’ll pay for it.

Best for Melbourne? Fibreglass or concrete. They last longer and need less maintenance. No-brainer.

Step 3: Build a Rock-Solid Foundation

Your pool is heavy. Without a strong base, it won’t last. Here’s what works:

• Concrete Slab – The strongest, longest-lasting option.
• Reinforced Timber Deck – Great for elevated swimming pools, but must hold serious weight.
• Compacted Gravel Base – Cheaper, but needs expert prep to stay stable.

Step 4: Place and Lock Down the Pool

Once the base is set:

• Crane or forklift to move the swimming pool shell into place.
• Level it up so it stays put—no shifting!
• Add steel framing for that extra muscle.

Step 5: Plumbing, Filtration & Electrical Setup

Water stays clean and safe with a solid filtration system.

• Install a pump and filter (sand or cartridge).
• Pick a sanitation method – chlorine, saltwater, or mineral.
• Set up heating – solar, gas, or electric heat pump.
• Get a licensed electrician for wiring—don’t risk it. Electrical installations for swimming pools must be completed by a licensed electrician in accordance with AS/NZS 3000:2018 Wiring Rules, which outline key safety requirements like bonding, RCDs, and installation clearances.

Step 6: Make It Look Like a Million Bucks

A pool without the right finishing touches? Looks unfinished. Here’s how to level it up:

• Decking – Timber, tile, or composite for a seamless, high-end look.
• Landscaping – Plants, lighting, and paving turn it into a backyard oasis.
• Fencing – According to Victorian pool safety regulations, fencing is mandatory for pools under 1.2m in height.

What Melbourne Homeowners Are Saying

“We needed a pool that could go in quickly without tearing up our backyard. The team installed our plunge pool in under 7 days—and it looks incredible. Zero regrets.”
— Henry & Shiela S., Altona VIC

Above-Ground vs. Inground Plunge Pools: Which One Wins?

Deciding between above-ground and in-ground? It comes down to cost, install time, and flexibility. Here’s why above-ground crushes it:

Why Go Above-Ground?

Whether you’ve got a sloped backyard, a tight inner-city courtyard, or just don’t want weeks of construction noise—above-ground pools offer unmatched flexibility for Melbourne homes.

• Got limited space? One family in Altona installed theirs on a compact rear deck—finished in under 7 days, no excavation needed.
• Renovating later? Take the pool with you or reposition it—perfect for homeowners who might extend or move.
• Tough terrain? Above-ground designs thrive on rocky or uneven ground where in-ground pools aren’t even an option.
• Want peace of mind? With higher walls, these pools naturally reduce risk for small kids and pets.

And unlike traditional pools, there’s no waiting around—just install, heat it up, and jump in.

The Downsides of Above-Ground Plunge Pools (Know Before You Buy)

• Doesn’t Blend In as Easily – small Inground swimming pools look more built-in.
• Needs a Solid Base – Requires a reinforced deck or concrete slab.
• Not as Deep – Usually 1.2m to 1.5m, shallower than inground.
• Aesthetic Upgrades Required – May need decking, cladding, or landscaping for a polished look.

Above-Ground vs. Inground Plunge Pools: Side-by-Side

Verdict?

Want a fast, affordable, and flexible pool? Go above-ground.
Want a permanent, high-end backyard feature? Go inground.

Both work. Pick what fits your lifestyle.

How to Keep Your Above-Ground Plunge Pool Clean & Running Like New

Skip maintenance? Enjoy a green, bacteria-filled swamp. Do it right? Crystal-clear water year-round. Here’s how:

Routine Cleaning & Water Treatment

• Test water weekly – pH, chlorine, alkalinity. Get it right.
• Vacuum or skim debris – Leaves, dirt, bugs? Gone.
• Shock the pool – Every few weeks to kill bacteria and keep it fresh.

Seasonal Maintenance Cheat Sheet

• Summer – Run the filter longer. More people = more dirt.
• Winter – Lower chlorine. Cover the pool. Keep the junk out.
• Spring/Fall – Check for leaks, cracks, and filter issues before they get worse.

Heat Your Pool Without Burning Cash

• Solar Heating – Free energy from the sun. Great if you get enough sunlight.
• Heat Pump – Runs efficiently year-round. No weather excuses.
• Gas Heater – Fast heating, but your wallet feels it too.

Keep Algae Out & Water Clear

• Use algaecide – Especially in humid months (or risk swimming in slime).
• Run filtration 6–8 hours daily – Still water = bad news.
• Cover the pool – Less debris. Less cleaning. More swimming.

1. Finishing Materials

Frequently Asked Questions

1. Can you put an above-ground plunge pool on a deck?

Yes—but your deck better be strong enough. Use steel framing or concrete footings to handle the weight. Get a structural engineer to sign off before installation, or risk a disaster.

2. Do above-ground plunge pools need fencing?

In Australia, pool fencing requirements are governed by the Australian Standard AS1926.1-2012. Generally, any pool with a depth greater than 300mm (including above-ground pools) must have a compliant safety barrier. The standard specifies that the baplumrrier must be at least 1.2 meters high, with no gaps exceeding 100mm, and must include a self-closing, self-latching gate.

It’s important to note that regulations can vary by state and territory. For detailed information, refer to the Swimming Pool & Spa Association of Australia’s overview of pool fencing rules

3. Can you heat an above-ground plunge pool?

Absolutely. Use solar panels (cheap), heat pumps (efficient), or gas heaters. Add a thermal pool cover to lock in heat and cut energy costs. Swim all year—even in Melbourne winters.

4. What are the structural requirements for an above-ground pool?

Your pool weighs tonnes. Weak foundation? Big problem. Here’s what works:

• Concrete Slab – Strongest. Most stable. Built to last.
• Compacted Gravel – Cheaper, but needs expert prep.
• Reinforced Decking – Great for elevated pools, but must handle serious weight.
