Then balance the water, clean the filter, inspect the cover, and follow the spa manufacturer’s instructions to prevent freeze damage. The right plan depends on your climate, expected use, and the specific model.
1. Choose whether to keep the tub running or shut it down
These are different preparation plans, not interchangeable checklists. Consider how often you expect to use the spa, whether freezing weather is likely, whether you can maintain reliable power and monitor the tub, and what your owner’s manual recommends. Jacuzzi’s manufacturer winter-preparation guide covers both operating a spa in winter and shutting it down.

| Consideration | Keep it running | Shut it down |
|---|---|---|
| Expected use | Choose this path if you plan to use the spa during cold weather. | Consider this if you do not expect to use it and want to close it for the season. |
| Cold-weather protection | Maintain water and circulation; use freeze-protection features only as directed for your model. | Drain the spa and clear water from the equipment and plumbing identified in the manual. |
| Owner’s role | Be prepared to maintain and monitor the spa in line with its instructions. | Be able to complete the model-specific draining and winterization steps, or seek help if needed. |
The available guidance does not establish a universal cost or risk advantage for either choice. Local conditions and the spa’s instructions should determine your plan.

2. Test the water and refresh it when due
Fall is a useful time to check water care, but it is not a universal deadline to drain and refill. The Pool & Hot Tub Alliance (PHTA) recommends testing pH, alkalinity, and sanitizer, then adjusting as needed. Its general guidance is to drain and refill every three to four months or as the manufacturer recommends; follow your spa’s schedule and the condition of its water. See PHTA’s consumer maintenance guidance.

A Kansas City dealer recommends an early-fall drain and refill for its local conditions, but that timing is regional—not a rule for every climate or spa. Its advice is available at Pool & Spa Patio’s fall maintenance guide.
3. Clean the filter and check the equipment
PHTA’s general maintenance cadence is to rinse the filter weekly and deep-clean it monthly with filter cleaner. If you are shutting the spa down, Jacuzzi advises removing and cleaning the filters and cleaning the filter basket as part of its preparation procedure. Check your manual for the correct method and any model-specific cautions.

4. Inspect the cover and secure it properly
Check that the cover fits closely and that its latches and seals are intact. Look for cracks, sagging, or signs it has become waterlogged. A well-fitting insulated cover helps retain heat and prevent freezing, according to PHTA; replace yours only if inspection shows a problem, and verify that any replacement fits your spa’s size and model. Jacuzzi advises keeping the cover firmly in place when the spa is not in use and securing it for shutdown. Its guide says: “Place your cover over your hot tub and lock it down.”
5. Use the right freeze-protection plan
If the spa will stay in service
Keep the spa filled and maintain water and circulation as the owner’s manual specifies. Some models have a freeze-protection mode, but features and temperature limits are model-specific. Jacuzzi describes such a mode for the models covered by its guide; do not assume your spa has the same feature or settings.

Bestway’s cold-weather guidance applies specifically to its inflatable spas equipped with its named Freeze Shield system. It is not a general instruction for other inflatable tubs or hard-sided spas. Check the guidance for your exact model before relying on an automatic protection feature.
If the spa will be shut down
Draining the visible water is not enough if water remains in plumbing or equipment: it can freeze. Follow the manufacturer’s winterization procedure, which may call for clearing water from pump fittings and jet plumbing, cleaning the shell, and securing the cover. Jacuzzi Canada also emphasizes clearing residual water from the pump housing, filter canister, heater, and jet piping. The exact components and steps depend on the spa. See its Canadian winterization guidance.

A wet/dry shop vacuum can help remove residual water from fittings and plumbing, as described in Jacuzzi’s U.S. winter-preparation guide, but it is not a substitute for completing every model-specific winterization step. If you cannot confidently drain the required equipment and plumbing, consider professional winterization rather than leaving water in the system.
