The present invention relates to a fluid circulation bath. The fluid circulation bath comprises: a fluid storage unit comprising a heater unit to heat a fluid and a temperature sensor to detect a temperature of the fluid; a first valve which is connected to a flow passage of the fluid storage unit and a pump unit, and opens or closes to allow the fluid heated by the heater unit to flow into the pump unit or block the fluid; a filter unit to remove an impurity of the fluid supplied by a pressure operation of the pump unit; a fluid level sensor to detect a level of the fluid supplied to a tub by a spray unit after passing through the filter unit; a second valve disposed on a lower end of the tub and connected to the fluid storage unit; and a control unit connected to the fluid level sensor, the temperature sensor, the heater unit, the first valve, the second valve, and a pump, in which a timer is embedded to set an operational time of the second vale. When the second valve is blocked, the fluid is accommodated in the tub. When the second valve is opened, the fluid is drained from the tub to the fluid storage unit. |
