PROBLEM TO BE SOLVED: To provide a jet bath system capable of suppressing an idling rotation of a pump and improving the freedom degree of a design even if a suction port and a nozzle are attached at positions lower than a non-self-suction pump.
SOLUTION: This jet bath system includes: a non-self-suction pump 7 sucking, pressurizing and discharging bathtub water; a bathtub 1 provided at a position lower than an operable water level of the pump and having a suction port 5 for sucking the bathtub water; and a conduit pipe 6 guiding the bathtub water sucked from the suction port 5 to the non-self-suction pump 7; and jets the bathtub water discharged from the non-self-suction pump 7 to the interior of the bathtub 1. A conduit line of the bathtub water discharged from the non-self-suction pump 7 has a second pipe 9 which is branched from a first pipe 8 provided at a position higher than the operable water level and guides the bathtub water to a nozzle 12 provided at a position lower than the operable water level, and a third pipe 10 which is branched from the first pipe 8 and has its downstream end provided at a position higher than the first pipe 8.
