The jet and bubble system of a home swim spa tub allows users to enjoy hydromassage in addition to swimming exercise. Year-round, users can experience muscle relaxation and improved blood circulation, regardless of the season.

If the water in a whirlpool spa hot tub hasn't been changed for a long time, or if the water source itself contains high levels of minerals, organic matter, or trace elements like iron and manganese, it can easily develop an unpleasant odor. Odors are particularly likely to occur under the following conditions: • Imbalanced pH • Excessive minerals • Insufficient disinfectant

Modern spa jacuzzi bathtubs typically use residual current devices (RCDs)/GFCIs. Once a leakage is detected, the system automatically shuts off power, preventing electric shock. Electrical components are typically waterproof, such as the pump body, motor housing, and heater housing, which have IP ratings to minimize the risk of water contacting electricity.
