A folding clamshell shower has a body containing a water passage, a water diversion unit and an outlet unit. The outlet unit is rotationally and pivotally connected with the body to form the folding clamshell structure. The outlet unit is provided with at least two outlet functions; the water diversion unit is mounted at the rotary pivot joint site of the outlet unit and the body, and comprises a water diversion body; the rotation of the water diversion body relative to the body can be driven by the rotation between the outlet unit and the body, the relative rotation between the water diversion body and the body controls outlet functions of the shower to pause or switch.
