Growing up we had a walk in shower, the way it was setup there was no way to reach in and not get hit by cold water. Especially a short kid with short arms, you were getting a full blast cold water trying to go "out" of the shower. The tap was the push-pull type and very difficult to modulate so limiting to low pressure trickle was basically a game of russian roulette. The best I could do was hug the wall and let it only get whatever corner of my body I wanted to sacrifice to temporary hypothermia that morning.
