Bath water cools off because it starts off warmer than its environment. Nature tends to have forces in play that even extremes out and this is no exception. The heat leaves the tub by several routes:
a bath full of cold water
The cold water room was called the "fridgedarium".

your body is cold because the air around you is colder than the water in a shower or bath unless you are taking a hot bath.---------------------AND when water evaporates it absorbs heat, taking that heat away from you.
Running a bath involves using a larger volume of water compared to just using cold water for other purposes, such as for drinking or washing hands. If your cold water runs out during a bath, it may indicate that your water heater is not able to keep up with the demand for hot water needed to fill the tub, or that the hot and cold water supply in your home is imbalanced. This can be due to various factors such as the size and capacity of your water heater, the water pressure in your plumbing system, or issues with your plumbing fixtures.
