How Much Does It Really Cost to Run a Hot Tub in 2025?

Owning a hot tub can bring joy and relaxation. But many hesitate, worrying about hidden costs¹. This guide simplifies everything you need to know about expenses.

Understanding costs can help you decide whether a hot tub fits your lifestyle and budget.

Let’s dive into detailed breakdowns, energy usage tips, and cost-saving strategies.

What Is the True Monthly Cost of Owning a Hot Tub?

Buying a hot tub is just the beginning. The monthly costs can add up, including energy, maintenance, and chemicals². It’s important to know what to expect.

On average, monthly costs range from $50 to $100 depending on usage and energy efficiency.

A closer look at the costs:

Key Expenses Breakdown:

Expense Type	Estimated Monthly Cost
Energy Usage	$30–$50
Chemicals (e.g., chlorine, pH balancers)	$15–$25
Maintenance (e.g., filters, repairs)	$10–$30

These numbers vary by location, energy rates, and hot tub type. Investing in efficient models³ can reduce long-term expenses significantly.

How Does a Hot Tub Impact Your Electricity Bill in 2025?

Electricity is a significant part of owning a hot tub. Heating water consumes most of the energy, especially during colder months.

A typical hot tub adds $20–$50 per month to your electricity bill⁴, depending on usage.

Factors Affecting Energy Costs:

• Insulation Quality: Better insulation reduces heat loss.
• Pump Efficiency: High-efficiency pumps use less energy.
• Cover Usage: A quality cover prevents heat escape.

Investing in energy-efficient models can save hundreds annually.

Are Hot Tubs Expensive to Maintain Over Time?

Maintenance costs include cleaning, water treatment, and occasional repairs. Neglecting these can lead to higher expenses later.

Over time, maintenance can cost $500–$1,000 annually⁵, depending on how well you care for the hot tub.

Essential Maintenance Tips:

1. Clean filters regularly to ensure proper water flow.
2. Test water chemistry weekly to avoid imbalances.
3. Schedule professional inspections to detect issues early.

Spending a little on maintenance saves big on potential repairs.

Do Hot Tub Jets Use More Electricity Than Expected?

Hot tub jets are powered by pumps, and their energy use depends on the number of jets and the pump’s efficiency.

Running jets during heating increases energy usage, but the impact is moderate.

Understanding Jet Usage:

• Standard Jets: Use around 2–3 kWh per hour.
• High-Performance Jets: May consume up to 5 kWh per hour.

Opt for models with variable-speed pumps to control energy use.

How Much Electricity Does It Take to Run a Hot Tub Monthly?

Electricity use varies by hot tub model, climate, and frequency of use. Efficient models consume less energy overall.

Most hot tubs use between 200–400 kWh per month.

Energy Usage Comparison:

Usage Type	Estimated kWh/Month
Basic Hot Tub	200–250
High-End, Insulated Tub	150–200
Poorly Insulated Tub	300–400

Selecting the right hot tub can make a big difference in energy savings.

What Are the Most Energy-Efficient Hot Tubs in 2025?

Energy-efficient hot tubs are designed to minimize energy use without compromising performance. They are ideal for environmentally conscious buyers.

Top models in 2025 include advanced insulation, energy-efficient pumps, and smart controls.

Features to Look For:

1. Full-Foam Insulation: Reduces heat loss significantly.
2. Energy-Saving Covers: Traps heat when not in use.
3. Smart Controllers: Adjust settings remotely for efficiency.

Investing in these features saves money and supports sustainability.

Is a Hot Tub Cheaper to Run Than a Swimming Pool?

Comparing hot tubs to swimming pools depends on size, usage, and energy needs. Hot tubs are often more cost-efficient for personal relaxation.

A swimming pool can cost $150–$300 monthly, much higher than most hot tubs.

Key Differences:

Feature	Hot Tub	Swimming Pool
Heating Costs	Lower	Higher
Maintenance Effort	Moderate	High
Space Requirements	Compact	Large

For small households, hot tubs offer better value for money.

Can Installing a Hot Tub Boost Your Home Value?

A hot tub can enhance your property’s appeal, especially in colder climates or luxury markets.

While not guaranteed, well-maintained hot tubs often increase property value by 3–5%.

Tips to Maximize Value:

• Keep the hot tub in excellent condition.
• Choose models that match your property’s aesthetic.
• Highlight energy-efficient features to appeal to buyers.

Should You Leave Your Hot Tub Running All the Time?

Hot tubs are designed to maintain consistent temperatures. Keeping them running can sometimes be more energy-efficient than reheating.

Leaving a hot tub running costs about $1–$2 daily in electricity.

Best Practices:

1. Use a high-quality cover to retain heat.
2. Lower the temperature when not in use for long periods.
3. Schedule heating during off-peak hours to save costs.

What Are the Cheapest Ways to Run a Hot Tub in 2025?

Reducing operational costs doesn’t have to be complicated. Small adjustments can lead to big savings over time.

Using energy-efficient components and smart habits can reduce costs by 20–30%.

Cost-Saving Strategies:

• Use solar-powered heating systems⁶.
• Turn off jets when not in use.
• Regularly clean and maintain filters to improve efficiency.

Does Running Jets While Heating a Hot Tub Save Money?

Running jets while heating distributes heat evenly, but it uses additional electricity. The savings are minimal, so it depends on personal preference.

Jets improve heating efficiency but increase electricity usage.

Key Takeaways:

• Use jets sparingly to balance efficiency and cost.
• Prioritize energy-efficient models for long-term savings.

Conclusion

Hot tubs offer relaxation, but understanding costs is essential for ownership. From monthly expenses to energy-saving tips, planning ensures a stress-free experience.
