In general, whether an exterior jacuzzi tub can be used when it rains depends on several factors, such as the design of the jacuzzi tub, weather conditions and safety precautions. If it is a light drizzle or short precipitation, there are no strict restrictions on the use of an exterior jacuzzi tub.

The main components of garden jacuzzi tub foam are organic matter in the water, such as body oils, cosmetic residues, and other impurities. Shock treatment can quickly decompose these organic substances by increasing the concentration of oxidants in the water, making them lose the ability to form foam.
