Foot massage baths with rotary knob
Rotary knob
— the most basic control method involves a rotary switch, allowing users to select from pre-defined operating modes for the bath, such as "vibration massage," "vibration + bubble," or "vibration + bubble + IR heating." While this control option offers fewer features compared to push-button control (as described in the relevant section), it aligns well with the limited functionality of the models in which it is employed, making it a suitable choice rather than a significant drawback.| rotary knob | clear | Save List |
