I don’t understand. Everyone faces the shower to begin with when they’re adjusting the temp. It seems like a bit of an effort to turn the shower on, wait for it to be the right temperature whilst the front of your body gets comfortably adjusted to the water to then just turn away. You can’t see the flow of water if your back is away from it and you can’t turn it off/nor adjust the temperature in an instant. You also have more nooks and crannies on the front of your body so it’s helpful to see the flow of water. It’s also less wasteful when you don’t make the water a blind spot.
The math ain’t mathing.
