Abstract: Provided are a treating liquid providing unit capable of predicting a temperature change of a substrate treating liquid by adding an inflow amount or consumption amount of the substrate treating liquid as a control factor, and a substrate treating apparatus including the same. The treating liquid providing unit includes a treating liquid storage module for storing the substrate treating liquid, a treating liquid heating module for heating the substrate treating liquid, a treating liquid discharging module for discharging the substrate treating liquid, a treating liquid supplying module for supplying the substrate treating liquid to the treating liquid storage module when the substrate treating liquid is discharged, and a control module for predicting the temperature of the substrate treating liquid remaining in the treating liquid storage module based on the inflow amount of the substrate treating liquid.
