If you want to achieve a therapeutic or deep relaxation effect with a spa hot tub, a regular model is difficult to achieve, while a dedicated hydrotherapy spa hot tub is the true hydrotherapy equipment.

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.
