A massage bathtub, also known as a jetted bathtub or hydrotherapy bathtub, is a specialized bathroom fixture designed to combine the basic function of bathing with therapeutic massage effects. It integrates modern hydraulics, electronics and material science, and is widely used in homes, hotels, spas and other places, becoming an important part of modern healthy and comfortable living.

The core principle of a massage bathtub is to use a built-in motor to drive the water pump, extract the water in the bathtub, mix it with air, and then spray it out through the nozzles installed on the缸 wall and bottom at a certain pressure. The impact of the water flow and the vibration of the bubbles act on the human body, simulating the effect of manual massage, thereby relieving muscle tension, promoting blood circulation and achieving the purpose of relaxation and health care.

The main components of a massage bathtub include three parts: the缸 body, the massage system and the control system. The缸 body is the main carrier, commonly made of acrylic, cast iron, artificial stone and other materials, with different shapes such as rectangle, ellipse and fan to adapt to different bathroom spaces. The massage system is the core part, including water pump, nozzles, pipelines and motors. The nozzles are divided into water jet nozzles and air jet nozzles, which can target different parts of the human body such as the back, shoulders and feet for massage. The control system is used to adjust the water flow intensity, massage mode, water temperature and other parameters, and the modern massage bathtub also supports intelligent control methods such as APP remote control and voice operation.

Unlike ordinary bathtubs, massage bathtubs pay more attention to the therapeutic and relaxing effects. Its design fully considers the ergonomics, so that the human body can maintain a comfortable posture during bathing, and the distribution of nozzles is also based on the acupoints of the human body to maximize the massage effect.
