This article was created using automation technology and thoroughly fact-checked and edited by an Angi Editor in accordance with our AI policy.

In 2026, the national average annual cost to run a hot tub is $700, with most homeowners spending between $350 and $1,100 depending on tub size, type, and insulation quality. Costs can climb as high as $1,500 for larger, custom-built tubs, while smaller standard models tend to land at the lower end of that range.

Hot Tub Cost Factors: What Affects the Price?

Several variables shape what you'll spend to run a hot tub, from the type and size of the tub to your local climate and the materials it's made from. Knowing which factors carry the most weight helps you make smarter choices before and after purchase.

Type

The type of hot tub you own is one of the biggest drivers of monthly running costs, with portable acrylic models costing $40 to $70 per month and swim spas reaching $90 to $120 per month. Aboveground and portable models are generally less expensive to operate than in-ground hot tubs, which run $80 to $100 per month. 

Inflatable tubs sit at the low end at $30 to $50 per month, though poor insulation can push their operating costs higher over time. Features like powerful jets, advanced lighting, and high-capacity heaters increase energy draw regardless of tub type, so costs vary by configuration as well. Hot tub monthly running costs vary by type, as the breakdown below shows:

Size

Hot tub size, measured by water capacity and seating, directly affects both energy and chemical costs, with small tubs running $30 to $50 per month and large tubs reaching $80 to $120 per month. Hot tub costs vary by configuration, as the table below shows:

Materials

The materials your hot tub is made from affect both its long-term durability and its ongoing energy costs. Acrylic shells paired with quality insulation trap heat effectively and help keep monthly bills lower, while vinyl and rotomolded plastic options are more affordable up front but tend to lose heat faster, which can increase heating expenses over time.

Hot tub material type affects both running cost and durability, as the comparison below shows:

Labor

Professional installation and maintenance labor costs vary by region and job complexity, with electricians and plumbers typically charging $50 to $150 per hour. Hot tub technicians may bill a flat fee or an hourly rate for setup and repairs, and scheduling regular servicing helps prevent the kind of breakdowns that lead to much larger repair bills.

Prep

Site preparation adds to your up-front investment and can include pouring a concrete pad, reinforcing a deck, or upgrading your electrical service. Permit fees, inspections, and the initial water fill round out the prep costs you should budget for before your tub is ready to use.

Tipping

Tipping hot tub delivery and installation crews is standard practice, with a typical range of $20 to $50 per crew member, or roughly 5% to 10% of the total installation cost. For ongoing service professionals, tipping is appreciated but not always expected; $10 to $20 is a reasonable amount for exceptional work.

Additional Cost Factors

Beyond the basics, several other factors can influence your total expenses:

• Removing and disposing of an old hot tub if you're replacing one

• Cleaning and debris removal after installation

• Additional permits and inspections for electrical or structural upgrades

• Modifying a foundation or deck for support

• Building framing or enclosures for in-ground or built-in models

• Adding landscaping, privacy screens, or fencing for safety and aesthetics

• Upgrading with steps, handrails, or custom exterior finishes

• Installing automation systems, lighting, or integrated sound systems

Ongoing Costs

Let's look at the recurring costs that make up your hot tub's total yearly expense, from routine maintenance to electricity, repairs, and insurance.

Maintenance

Routine maintenance keeps your hot tub safe and enjoyable, covering tasks like weekly water testing ($5 to $10 per month), monthly filter cleaning, and regular chemical additions. Some homeowners opt for an annual maintenance plan, which runs $350 to $600 per year, for added convenience and peace of mind. Hot tub maintenance costs vary by task and frequency, as the breakdown below shows:

Operating Costs

Electricity is your largest ongoing operating expense, running $20 to $60 per month, depending on your local utility rates, tub size, and how frequently you use it. Water refills add $2 to $10 per month, with higher costs if you drain and clean your tub several times a year, and heating costs range from $10 to $40 per month, depending on your heat source. Hot tub operating costs broken down by category are shown below:

Repairs

Heater and pump issues are the most common (costing up to $700), followed by leaks, jets, and control panels. Emergency service calls can add $100 to $200 on top of repair costs, so budgeting for unexpected expenses is a smart part of hot tub ownership. Hot tub repair costs vary by component as shown below:

Insurance

On average, expect your annual premium to increase by $50 to $150, depending on your policy terms and location. Adding a hot tub can affect your homeowner's insurance, with some providers requiring additional coverage for damage or liability.

DIY Hot Tub Operation vs. Hiring a Pro

Deciding between DIY and professional installation or maintenance affects both your wallet and your peace of mind. DIYers can save on labor costs by handling setup and routine care themselves. For installation, this might mean savings of $500 to $2,000, depending on complexity. Maintenance tasks like cleaning filters or testing water require basic tools and safety gear but are manageable for many homeowners.

However, professional installation ensures all electrical and plumbing connections meet safety codes. Improper setup can void warranties and lead to costly repairs down the road. DIY maintenance saves money, but lack of experience can lead to errors, higher long-term costs, or even safety hazards.

Consider hiring a pro for:

• Electrical and plumbing installation

• Major repairs or troubleshooting

• Annual deep cleaning or servicing

For most homeowners, a combination of DIY upkeep and local hot tub installation pro servicing offers the best balance of savings and safety.

Hot Tub Operation Add-Ons

Enhancing your hot tub with add-ons can improve comfort, safety, and energy efficiency. Here are some popular upgrades and their typical costs:

• Upgraded insulated cover: $200 to $600

• Locking cover: $100 to $300

• Steps and handrails: $100 to $500

• Water features (fountains, waterfalls): $200 to $1,000

• LED or underwater lighting: $100 to $400

• Exterior lighting: $100 to $600

• Sound system or entertainment features: $300 to $1,200

• Ozonator or saltwater system: $250 to $1,000

• Automation or smart controls: $200 to $1,000

• Custom enclosure or gazebo: $2,000 to $10,000

• Energy-efficient pump or heater: $400 to $1,500

• Winterizing kit or accessories: $100 to $300
