How much does a spa cost in Australia? [2026 Price Guide]

Picture this: you're out at a friend's place, it's a cool autumn evening, and there's a spa bubbling away in the corner of the backyard. You've been thinking about getting one yourself for ages, but you've got no idea how much the project would cost. 

Depending on what you get, spa installation costs in Australia range from around $500 for a basic inflatable you can set up yourself to $35,000 or more for a custom in-ground build. Type, size, and material, and other variables would dictate the total cost for your dream home spa. 

This guide breaks down how much a spa costs so you can set a realistic budget before you start getting quotes.

What is a swim spa?

A swim spa is a compact pool with a built-in current that lets you swim in place. Some models have a split design, with a hot tub zone at one end and a swimming area at the other. 

Swim spa costs in Australia range from around $19,000 for entry-level models to $55,000 or more for premium dual-zone options.

Spa vs hot tub vs Jacuzzi: What's the difference?

In Australia, "spa" and "hot tub" are used interchangeably. Both refer to a heated, jetted tub used for relaxation or hydrotherapy. "Jacuzzi" is a brand name that has become a catch-all term for the premium end of the market, in the same way "Esky" became shorthand for any cooler.

Average spa installation costs by city

The type of spa you choose is the single biggest cost variable, but where you live also plays a role through differences in labour rates, site conditions, and local permit fees. Here's a snapshot of average spa pool costs in Australia by city.

Type

Jet type affects both the feel of the spa and its price. Options range from air-and-water rotating jets to directional jets and pulsing massage jets. The more sophisticated the system, the higher the price tag.

Material

The material affects both upfront cost and long-term durability. Inflatable soft tubs are the most affordable and the easiest to set up yourself. Meanwhile, fibreglass and concrete cost more upfront, but they last considerably longer.

Size

Larger spas cost more to install, and many suppliers price by seating capacity. A 1–2 person tub is significantly cheaper than one designed for 5–6 people, so it's worth being realistic about how many people will actually be using it at once.

Location and excavation

In-ground spas require excavation, and the more digging involved, the higher the cost. Talk to your installer about the best spot in your yard before work begins, as some locations are significantly cheaper to excavate than others.

Indoor vs outdoor

An indoor spa lets you use it year-round regardless of the weather, but it typically calls for home modifications, including improved ventilation and reinforced flooring to handle the weight. All of that adds to the overall cost. On the other hand, outdoor spas are simpler and cheaper to install, though you'll need a cover to protect the tub when it's not in use.

In-ground vs above-ground

An above-ground spa costs around $2,000 for a portable model. In-ground spa costs in Australia typically range from $10,000 up to $25,000, depending on size and finish. This is just slightly cheaper than a full pool build.

Electrical and plumbing

Your electrical setup’s complexity scales directly with the power of your spa. While it might be tempting to save money, never attempt to DIY the electrical hookup; it is illegal in every Australian state and genuinely dangerous. Most installations begin with a consultation from a licensed electrician to determine which of these three paths your project requires:

• At the simplest level are Plug-in (10A) models. These smaller, single-pump spas are designed to run from a standard outdoor power point. Installing a new weather-protected point typically ranges up to $300.

• Mid-range spas often require a Dedicated 15A circuit. These units draw more current than a standard household appliance, so an electrician must run a dedicated line from your switchboard to the spa. You can expect to pay between $300 and $600 for a professional installation.

• For larger multi-pump or premium units, a Hardwired (32A) connection is mandatory. This is the most complex setup, often requiring trenching for underground cables and a dedicated isolation switch. Costs for this level of work generally range from $900 to $2,500. Keep in mind that if your home has an older switchboard, an upgrade may be necessary to safely handle the new load, adding an additional $800 to $1,500 to the total.

Accessories

A spa cover is crucial for retaining heat, keeping debris out, and ensuring safety. In most states, your cover must meet AS1926.1 child safety requirements. A quality lockable hard cover starts from around $650 to $975 for standard spa sizes, with larger models running $1,400 or more. Budget covers (solar bubble blankets) start lower but don't meet safety barrier requirements on their own.

You'll also need a solid base. A standard 100mm reinforced concrete slab typically costs $800 to $2,500, depending on size and site conditions. If you're planning a deck around the spa, it needs to be engineered to handle the load.

Ongoing maintenance

It's worth factoring in running costs before you commit. Regular draining, scrubbing, and chemical treatment can be done yourself or handed off to a pro. A well-insulated spa adds roughly $30 to $50 a month to your electricity bill in summer and $60 to $100 in winter, plus several hundred dollars a year in chemicals and filter upkeep.

Spa costs by type

The most affordable option. Portable spas are easier to install and straightforward to move if you need to. Entry-level models start from around $500, with mid-range options typically sitting between $1,000 and $3,000. Installation costs are lower than for in-ground options, though you'll still want a licensed electrician for the hookup.

Custom-built spa

Custom spas let you design around your space and style. Think integrated lighting, water features, or a shape that wraps around an existing pool. Expect to pay between $10,000 and $35,000 for a custom build, with more complex projects sitting toward the higher end.

In-ground spa

An in-ground spa is a permanent fixture that can add real value to your property, especially when it’s paired with a pool or quality landscaping. Prices generally ranges from $10,000 to $20,000.

Above-ground spa

Above-ground spas range from $3,000 to $18,000. They're technically portable, but most weigh over 100 kilos once filled, so moving one after installation is no small job.

Spa costs by material

Fibreglass

A fibreglass spa for 1–4 people typically costs between $4,000 and $8,000. Family-sized models cost several thousand more. Fibreglass is the most popular choice in Australia for its balance of durability and price.

Concrete

Concrete spas require excavation, which adds to the overall cost depending on the scope. Purchase prices generally fall between $5,000 and $15,000.

Timber

A timber spa costs between $4,000 and $10,000. Acrylic models tend to run a little higher, up to $15,000.

Inflatable

The most budget-friendly entry point. Inflatable spas start from around $330 to $500 at the lower end, with better-quality models ranging up to $3,000. They're easy to set up yourself, but they're less effective at retaining heat and more vulnerable to punctures than hard-shell options.

Outdoor vs indoor spa costs

Outdoor

Outdoor spa costs for installation (labour only, not including the tub) typically run between $3,000 and $7,000, depending on how much site preparation and excavation is needed.

Indoor

Installing a spa indoors usually means structural modifications: ventilation upgrades, reinforced flooring, and potentially dedicated drainage. Budget between $10,000 and $25,000 for those changes alone, though simpler setups with less prep will sit toward the lower end.

Spa removal costs

If you’re replacing an existing spa, factor in removal costs. Most companies charge a flat rate of $300 to $800 for standard spa removal. If the spa just needs fixing, you can expect to shell out $90 to $200 for repairs.

Hiring a spa installer

Installing a spa requires careful planning and the right experts to ensure safety and compliance. Here are some tips to help you find a good service provider. 

Getting an accurate quote

• Get a separate quote for excavation, as it's often the biggest variable in the total cost for in-ground installations.

• Ask a licensed electrician for a quote before committing, since an electrical setup is required for most spa types, and the price varies more than people expect.

• For indoor spas, ask upfront exactly what structural modifications are needed so there are no surprises once work starts.

• Compare at least two or three providers before deciding, since prices and warranty terms vary significantly across the market.

Permits and licensing

Most states require a building permit to install a spa, and the rules vary. In Western Australia, for example, a compliant barrier is required for any pool or spa deeper than 300mm. 

Your installer should know your state's requirements inside out. If they seem vague on this, take it as a warning sign. Contact your local council to confirm what's needed before any work begins.

Keeping costs down

• If financing is offered, work out the total repayment amount before signing anything. Interest can add thousands to the final cost and change whether a premium model is actually a better value.

• Hire a licensed electrician for the electrical hookup. DIY electrical work on a spa is dangerous, and fixing it later will cost more than getting it right the first time.
