How to Prepare Your Hot Tub Before Vacation

Vacations require plenty of preparation. Between packing, making travel arrangements, and finding care for pets or plants, it’s easy to overlook one more item at home: your hot tub.

A filled spa should not simply be ignored while you’re away. Without proper circulation and water care, sanitizer levels can fall, water quality can deteriorate, and freezing temperatures may damage the plumbing.

The right preparation depends on your hot tub model, sanitation system, local climate, and the length of your trip. Always begin with the instructions in your owner’s manual.

1. Check and Balance the Water

Test the spa water shortly before leaving. Adjust the sanitizer, pH, alkalinity, and other required levels according to your owner’s manual and water-care system.

Starting with properly balanced water helps the sanitizer work effectively while the spa is not being used.

If the water is already cloudy, foamy, discolored, or difficult to balance, correct the problem before your trip. Depending on its condition, you may need to clean the filters, treat the water, or drain and refill the spa.

2. Clean the Filters

Rinse or clean the filters according to the manufacturer’s instructions. Clean filters support proper circulation and help remove debris while you’re away.

Inspect them for damage or heavy buildup. Replace any filter that is torn, worn, or remains clogged after cleaning.

3. Follow Your Water-Care Instructions

Maintain an appropriate sanitizer level using products approved for your hot tub. Chlorine and bromine are common spa sanitizers, but the correct products and amounts depend on your specific water-care system.

An ozonator, mineral system, or other supplemental system may reduce some maintenance requirements, but it does not replace an approved sanitizer. Follow the instructions provided with your spa and sanitation equipment.

Never mix chemicals, and do not add extra product simply because you will be away. Use only the amount directed by the manufacturer or product label.

4. Shock the Water, if Recommended

If shocking is part of your regular water-care program, treat the water before leaving according to the product label and your owner’s manual.

Spa shock helps oxidize contaminants that can consume sanitizer and contribute to cloudy water or unpleasant odors. After adding it, allow the spa to circulate for the recommended amount of time.

Some treatments require the cover to remain open temporarily so gases can escape. Follow the product directions before closing and locking the cover.

5. Keep a Filled Hot Tub Running

Unless your owner’s manual or a qualified spa professional directs otherwise, do not switch off a filled hot tub before leaving. The spa may need power for filtration, circulation, heating, and freeze protection.

If your model includes a vacation, economy, or away mode, consider activating it. You may also be able to lower the temperature to save energy, provided you remain within the manufacturer’s recommendations.

In freezing weather, maintaining power is especially important. A power outage or equipment failure can allow water inside the plumbing to freeze and cause serious damage.

6. Secure the Hot Tub Cover

Close the cover completely and fasten every locking strap or clip. A properly fitted cover helps:

Keep out leaves, dirt, and other debris
Reduce heat and water loss
Protect the spa interior from sunlight and weather
Discourage unauthorized access

Before leaving, inspect the cover and fasteners for damage. A locking cover is an important safety feature, but it should be used along with any barriers or access controls required in your area.

7. Arrange for Someone to Check the Spa

For a longer trip, ask a trusted person or professional spa-maintenance provider to inspect the hot tub periodically.

Give that person clear instructions for checking:

Water level
Water clarity
Sanitizer and pH
Filter operation
Spa temperature
Error messages
Leaks or unusual sounds
Power to the equipment

Do not ask an inexperienced person to guess chemical amounts. Leave written instructions and only the products required for your spa.

What If You’ll Be Away for an Extended Period?

There is no single number of days that applies to every hot tub. Your sanitation system, climate, water condition, and access to maintenance all affect how long a filled spa can safely remain unattended.

If nobody can check the hot tub during a lengthy absence, contact your dealer or service professional. They can help you decide whether the spa should remain operational or be drained and properly winterized.

Draining is not the same as winterizing. Water may remain inside pumps, jets, and plumbing even after the shell is empty. In freezing conditions, incomplete winterization can cause costly damage. Have the spa professionally winterized if you are not confident in the procedure.

What to Do When You Return

Before using your hot tub again:

Remove and inspect the cover.
Check the water level, clarity, color, and odor.
Confirm that the pumps and filtration system are operating normally.
Test the sanitizer, pH, alkalinity, and other required levels.
Clean the filters if needed.
Adjust or treat the water according to your water-care instructions.

If the water is cloudy, has a strong odor, contains visible growth, or cannot be balanced, do not use the spa. Follow the manufacturer’s troubleshooting process or drain, clean, and refill it before soaking.
