A gas mist pressure bathing system, which integrates a gas introduction part for increasing the supply pressure of a gas mist with a gas mist generator and enables the structure to be simplified and costs to be reduced, is provided. The gas mist pressure bathing system is provided with a gas supply means (10), a gas mist generating means (30), and a living body cover member (50). The gas mist generating means (30) is provided with, in an integrally formed manner: a connection part that connects to the gas supply means (10); a branched part that forces the gas flow from the connection part to branch off; a liquid storage part; a nozzle that discharges one of the gas flows that branched off at the branched part; a liquid-suctioning tube that transfers the liquid to the nozzle tip; a collision member that generates a gas mist by causing the liquid blown upwards by the gas flow discharged by the nozzle to collide; a merging part that merges the gas from above with the gas mist that was generated; a gas introduction part that guides the other gas flow that branched off at the branched part to the merging part; and a gas mist discharge part that collects and discharges the gas mist and gas that were generated.
