How Much Does It Cost to Repair a Hot Tub Yourself?

Depending on the size of the problem, you may be able to handle repairs yourself. Small cracks and leaks, for example, are relatively easy fixes and usually only require you to apply sealant to the problem area. 

Repairing a leak in the hot tub’s shell will cost between $10 and $20 to fix yourself. Find materials and supplies at your local home improvement store and ask the pros there for guidance.

Another easy-to-fix issue is a broken or worn-out filter. You should replace your hot tub filter at least once a year to prevent water quality issues down the road. Filter costs range from $25 to $50 and you can find them at most home improvement or home goods stores.

Most professional hot tub repair experts charge $75 to $125 per hour, so DIYing a small repair can save you hundreds on labor costs.

We recommend calling a pro if your hot tub requires electrical or plumbing work. Attempting a complex repair without the necessary skills risks damaging the tub beyond repair, which will leave you missing your favorite after-work activity. Afterall, installing a new hot tub can cost $16,000 or more.

Hot Tub Repair Cost Breakdown

Factors that determine hot tub repair costs include labor and materials. Costs for each project will vary, but this price breakdown will help you budget.

Labor

Hot tub repair pros charge between $75 to $125 per hour and repair times range from one hour to several. So, overall labor costs will likely cost you between $75 and $750 total

Some workers also charge a diagnostic fee to assess the situation before they begin work, which will cost between $100 and $200. You may be able to get a discount if you hire the same worker who performed the diagnostic inspection to fix the problem.

Materials

On top of the labor costs associated with fixing a hot tub, you’ll also have to pay for materials. A new filter will cost up to $25, while hot tub pumps will be more costly at $200 to $1,200.

Factor in up to $1,200 in material costs when budgeting for a hot tub repair.

Hot tub repair costs will vary depending on the type of problem that needs fixing. Some small issues, like surface leaks, may be DIYed and therefore less costly to complete. Others require a professional.

Here’s a look at how much it costs to repair a hot tub broken down by issue:

Type of RepairAverage Cost of Repair
Leaking Water$25 – $1,500
Jet$75 – $300
Heater$225 – $650
Hot Tub Pump$200 – $1,200
Circuit Board$200 – $700
Hot Tub Blower$175 – $450
Frame or Cabinet Damage$60 – $125

Leak

Several things could cause a leak in your hot tub, including a faulty pump, a connection issue, or simply damage to the shell. You can usually fix a small crack or leak in the shell yourself by applying sealant, which costs around $25 at most home improvement stores.

Larger leaks warrant a call to an expert hot tub repair service. Expect to pay anywhere from $200 to $1,500 for leak repair. If the leak is in a hard-to-reach spot, like near the hot tub frame, the price will increase to at least $2,000.

Jet

You need to replace your jet if it’s not turning on or off, or the water pressure is too high or too low. New jets cost $75 to $100, and the cost to replace them ranges from $150 to $200 per jet.

Feeling confident? Owners can usually replace a broken jet themselves because many models allow you to easily unscrew them. But to be safe, ask an expert for guidance on which jet type to buy before you get to work. 

Heater

Run-down hot tub heaters may fail to heat the water in the tub, or they could lead to issues like improper water chemistry or burned-looking spots on the tub’s shell. Heaters usually last about five years, at which point you’ll need to replace them.

The cost to replace a hot tub heater will vary from tub to tub, depending largely on the make and model. Some hot tubs require high-end heaters to function, while others may be less expensive to replace. 

Hot tub heater replacement costs range from $225 to $650, including the new heater. 

Pump

Several things can indicate a problem with your hot tub’s pump. If there is no water coming out of the jets or if no water is flowing when the pump is making noise, a faulty pump is likely the culprit. Also, watch out for water leaks near the pump.

Hot tub pump replacement cost falls between $200 and $1,200

There are two types of pumps—circulation and two-speed. Circulation pumps cost between $200 and $500 (not including installation) and two-speed pumps cost from $750 to $1,200 to replace.

Circuit Board

A hot tub’s circuit board is essentially its control center. A broken or worn-out circuit board can lead to an array of problems, including inconsistent jet function and lighting issues. Replacing the circuit board will cost between $200 and $700 and will always require an assessment from a spa or pool professional.

Blower

Issues with a hot tub blower can cause erratic jet and blower speeds or problems with the air switch. Hot tub blower replacement costs, including the cost for the replacement part, will be $175 to $450 total.

If your blower needs repair and not replacement, you will pay less. Ask an expert to determine if the issue is fixable or not.

Frame/Cabinet

Building a frame or cabinet around a hot tub gives the area a good-looking boost and enhances its privacy. Consider adding one around yours if your neighbors are too close for comfort or if you live on a busy street.

Rambunctious kids, harsh weather, and normal wear-and-tear can damage the cabinet, so you may need to repair or rebuild it from time to time. Damage to the frame’s structure could cause it to fall onto the hot tub’s shell.

To repair or rebuild your tub’s cabinet, consult a local handyperson or a contractor near you. These pros typically charge between $60 and $125 per hour and can identify weaknesses in the frame and repair them quickly.

  8. An error code appears on the hot tub control panel.

Hot Tub Servicing and Maintenance Costs

  • Tripped breakers

  • Any exterior or structural damage

  • Proper jets function

  • Malfunctioning heating element
