How Much Does It Cost to Run a Spa in Australia? (2026 Guide)

If you're thinking about buying a spa, one of the first questions you'll probably ask is:

"How much does it actually cost to run?"

The good news is that modern, well-built spas are far more energy efficient than many people think.

In fact, choosing a quality Australian made spa with excellent insulation can make a significant difference to your electricity bills compared to a cheaper imported model.

At Pool World Australia, we're often asked about running costs for our Australian Made Sapphire Spas, so we've put together this guide to help you understand what to expect.

The Short Answer

For a quality, well-insulated spa that's maintained at temperature year-round, most Australian homeowners can expect to spend approximately:

• $1.50–$3.00 per day
• Around $45–$90 per month
• Approximately $540–$1,080 per year

Actual running costs will vary depending on your electricity tariff, local climate, spa size, how often it's used and the quality of its insulation. Heating is the largest contributor to energy use, so efficient insulation and a quality cover make a big difference.

What Affects Spa Running Costs?

Not every spa costs the same to operate.

Here are the biggest factors that influence your electricity bill.

1. Insulation Makes the Biggest Difference

Think of your spa like a thermos.

The better it's insulated, the less heat escapes—and the less often the heater needs to switch on.

A poorly insulated spa loses heat quickly, meaning it uses more electricity to maintain your chosen water temperature.

This is one of the biggest reasons we recommend Australian Made Sapphire Spas.

They're engineered with premium insulation systems and quality thermal covers to help keep heat where it belongs—in your spa.

2. Your Location

Living in Perth is actually an advantage.

Our relatively mild winters mean spas generally use less energy than they would in colder parts of Australia.

While winter running costs will be a little higher than summer, Perth homeowners can still enjoy their spa all year without excessive electricity bills.

3. How Often You Use Your Spa

Many people assume using their spa more means dramatically higher running costs.

In reality, once the water is already at temperature, enjoying your spa regularly doesn't add as much to your power bill as most people expect.

Heating cold water from scratch uses far more energy than maintaining the correct temperature.

That's why most manufacturers recommend keeping your spa heated if you use it regularly.

4. Your Spa Cover

Your spa cover works harder than you might think.

Most heat escapes through the top of the spa.

A thick, insulated cover helps:

• Reduce heat loss
• Lower electricity consumption
• Keep debris out
• Reduce water evaporation

Replacing an old or damaged cover can significantly improve efficiency. Industry guidance consistently identifies a well-fitting insulated cover as one of the easiest ways to reduce running costs.

5. Water Temperature

The hotter you keep your spa, the more energy it will use.

Most owners find a temperature between 37°C and 38°C provides the perfect balance between comfort and efficiency.

Even reducing the temperature slightly when you're away for several days can help save electricity.

Why Sapphire Spas Are Designed to Save You Money

Not all spas are built the same.

A cheaper spa may seem like a bargain initially, but poor insulation and lower-quality components can result in higher running costs year after year.

Sapphire Spas are designed with energy efficiency in mind, featuring:

✔ Premium insulation
✔ Quality thermal hard cover
✔ Efficient heating systems
✔ High-quality plumbing and components
✔ Australian engineering for Australian conditions

Better insulation means less heat loss, reduced energy consumption and lower ongoing ownership costs.

How to Keep Your Running Costs Low

Here are a few simple ways to maximise efficiency:

• Always keep your insulated spa cover on when not in use.
• Maintain clean filters so water flows efficiently.
• Keep your water balanced to reduce strain on equipment.
• Service your spa regularly.
• Position your spa in a sheltered location where practical.
• Check your cover regularly for damage or waterlogging.

Small maintenance habits can make a noticeable difference over the life of your spa.

Is It Worth Buying a Quality Spa?

Absolutely.

When comparing spas, many people focus only on the purchase price.

However, it's the long-term cost of ownership that really matters.

A quality Australian made spa may cost a little more upfront, but can reward you with:

• Lower electricity costs
• Greater reliability
• Better insulation
• Fewer repairs
• Longer lifespan
• Easier access to parts and service

That's value you can enjoy for many years.

Frequently Asked Questions

Does a spa use a lot of electricity?

Modern, well-insulated spas are much more efficient than many people expect. Running costs depend on insulation, usage, climate and electricity prices, but quality models are designed to minimise energy consumption.

Is it cheaper to leave a spa on all the time?

If you use your spa several times a week, maintaining the water temperature is generally more efficient than repeatedly heating it from cold.

Are Australian made spas cheaper to run?

Many Australian made spas, including Sapphire Spas, are built with high-quality insulation and efficient components that can help reduce energy use compared with poorly insulated alternatives.

Can I reduce my spa running costs?

Yes. Using a quality insulated cover, keeping filters clean, maintaining balanced water and servicing your spa regularly can all help improve efficiency.
