This was at my grandfather's house, there was no flowing water, the water was coming from a manual pump, hot water was only there if my grandmother had done it on the stove. So mostly we used cold water.
At the army i started with a finishing cold shower as long it would not be uncomfortable. Now i not need warm water, only at the bathtub. But after long bicycle distances a cold bathtub is the best. Others use ice inside the water, i haven't.
