Compare amounts of hot water to that of cold water used during a comfortably warm shower?

During a comfortably warm shower, the amount of hot water used typically surpasses that of cold water. This is because the hot water is mixed with cold water to achieve a pleasant temperature, with the hot water often constituting around 75-90% of the total flow. The exact ratio can vary based on personal preference, the desired water temperature, and the efficiency of the showerhead. Thus, while cold water is necessary for mixing, hot water generally dominates in volume.
