Are Hot Tubs Expensive to Maintain Long Term?

Owning a hot tub can be a fantastic experience — whether you’re relaxing after a long day, enjoying time with family, or soaking your muscles after exercise. However, many people are surprised by the ongoing costs associated with owning and maintaining a hot tub. While you may be familiar with the initial cost of purchasing the tub itself, there are several hidden costs that often get overlooked. At Hydropool, we believe in transparency, which is why we want to help you understand the full financial picture of hot tub ownership.

In this article, we’ll break down the hidden costs that come with owning a hot tub, so you can prepare yourself for the long-term investment and enjoy your hot tub without any surprises.

Here’s what we’ll cover:

• Initial Purchase Costs
• Ongoing Maintenance and Operational Costs
• Energy Costs
• Water Care and Chemicals
• Replacement and Repair Costs
• Insurance and Permitting Fees

Initial Purchase Costs

While the price of a hot tub varies depending on the brand, size, and features, it’s essential to consider the initial investment. In 2025, the typical cost of purchasing a Hydropool Hot Tub ranges between $7,000 to $20,000 USD, depending on the model and features. Additional costs might include delivery and installation, which can add a few hundred to a few thousand dollars to the final price tag. For example, the cost of installing a hot tub may require hiring a contractor for electrical work or modifying your backyard.

Before committing to a hot tub, be sure to budget for these initial costs. It’s also wise to set aside some extra money for landscaping, decking, or any other backyard modifications that might be required.

Ongoing Maintenance and Operational Costs

Once your hot tub is installed, the ongoing maintenance and operation costs can add up over time. It’s important to plan for the following:

1. Energy Costs

Keeping your hot tub heated and ready for use comes with an energy cost. Depending on your usage and the size of your hot tub, you can expect to pay anywhere from $20 to $50 USD per month for electricity to run the heater and jets. Hydropool models are designed to be energy-efficient, which helps reduce operational costs.

2. Maintenance Costs

Regular maintenance is key to keeping your hot tub in good working condition. Maintenance costs include cleaning, replacing filters, checking the water’s pH, and using chemicals to keep the water balanced. On average, you can expect to spend about $300 to $800 USD per year on maintenance. With Hydropool’s Self-Cleaning Hot Tubs, maintenance is further simplified, but you’ll still need to replace the filters periodically and occasionally service your hot tub.

Water Care and Chemicals

Water care is essential for maintaining clean, safe, and comfortable water in your hot tub. The right chemicals and treatments help prevent algae, bacteria, and other contaminants, ensuring your tub remains safe to use. Here’s a breakdown of what you’ll need:

1. Chemicals

To keep your water balanced, you’ll need a variety of chemicals, including:

• Sanitizers (e.g., chlorine or bromine) to kill bacteria and maintain safe water.
• pH balancers to ensure your water is neither too acidic nor too alkaline.
• Algaecides to prevent algae growth.
• Clarifiers to keep the water clear.

On average, the annual cost of chemicals for a hot tub can be around $100 to $300 USD, depending on how often you use it and the type of chemicals you prefer.

2. Water Changes

While hot tubs generally require fewer water changes than pools, it’s still necessary to drain and refill the water every 3-4 months. You’ll need to budget for the cost of water and possibly a water filter replacement. This can cost anywhere from $50 to $150 USD per year.

Replacement and Repair Costs

Hot tubs are designed to last, but like any mechanical system, they require occasional repairs or part replacements. Some of the components that might need replacement over time include:

• Filters: Typically need to be replaced every 12-18 months, costing around $50 to $150 USD.
• Heater Elements: Over time, heater elements may degrade and need replacing, costing anywhere from $200 to $500 USD depending on the model.
• Jets: If a jet becomes damaged or malfunctions, replacing it can cost between $50 to $150 USD.

It’s a good idea to set aside a small budget for unexpected repairs or parts replacements, especially if your hot tub is older.

Insurance and Permitting Fees

Though not always a consideration for everyone, some homeowners might need to account for insurance or permits related to hot tub ownership:

1. Homeowners Insurance

Some insurance companies may require you to update your homeowners insurance policy to include your hot tub. This can result in a slight increase in your premiums, usually ranging from $50 to $200 USD per year, depending on your provider.

2. Permitting Fees

In some areas, you may need a permit to install a hot tub, particularly if electrical work or extensive plumbing is required. Fees for these permits can vary widely, but they typically range from $50 to $500 USD, depending on local regulations.

Understanding the Hidden Costs of Hot Tub Ownership

While owning a hot tub can be an enjoyable and relaxing experience, it’s important to factor in the hidden costs of ownership. Beyond the initial purchase price, ongoing costs for maintenance, energy, chemicals, and repairs can add up over time. However, by planning for these costs in advance, you can ensure that your hot tub remains a source of enjoyment for years to come.
