In a dry indoor environment with a temperature maintained between 15°C and 30°C, a spa hot tub can typically be left unused for 2-3 months without significant damage. If exposed to the outdoors, wind and sun will accelerate the aging of the casing and seals. Even with a dust cover, it is recommended not to leave it unused for more than 4-6 weeks.

Swim spa tubs are not "only" placed on concrete floors, but they must be placed on floors that meet the requirements for load-bearing capacity and stability. Concrete floors are simply the easiest way to meet these requirements.

The water temperature is typically maintained at 37–40°C. Full-body immersion causes peripheral vasodilation and accelerated circulation. This not only helps with overall relaxation but also improves nasal blood flow, gradually reducing swollen mucosa and alleviating nasal congestion.

If the swim spa tub is primarily used for aquatic exercise or rehabilitation training, the ideal temperature is 26°C–30°C. This temperature range helps maintain alertness, prevents overheating, and preserves athletic performance.

If multiple people use it daily, it is recommended to test and add chlorine as needed daily. If used occasionally, adding chlorine 2–3 times per week is sufficient. In summary, in most cases, it is recommended to test the water quality of a swim spa tub at least every 2–3 days and add chlorine as needed.

Most countries and regions have clearly defined maximum temperatures for hydrotherapy hot tubs. The U.S. Consumer Product Safety Commission (CPSC) recommends a maximum temperature of 104 degrees Fahrenheit to balance comfort and safety.
