A user may then selects and operates a first control system, or a second control system, or a combination of both. The first control system comprises motor speed regulation, which allows for setting of the operation speed of a motor and when the control system is activated, an operation timing process starts, wherein the operation timing process is a time countdown process. When the timing process is done, it may be re-started or a water-feeding process starts. When water-feeding process is selected, a water feeding timing process and water feeding detection start. When the water level is lower than a predetermined threshold, a force cleaning process is started, which drains residual water in the massage bathtub. It is also provided with magic color light control and light color setting control. The magic color light is used to provide variable lights of different color and brightness whereby a soft light mentally and physically relaxes a user. The color setting fixes the color of the magic light to have the magic color light to continuously emit light of the fixed color.
