That seems like a more realistic suggestion to me.
If you want to take this further, switch to taking Navy showers: get wet, turn off shower, apply soap, turn on shower to rinse off.
What, all my life I thought that was the normal way of showering. So how do you people actually shower? You leave the tap on while soaping?
Yes, I believe that is the common way of taking a shower. Turn on the water, do whatever you need for approximately 10 minutes, then turn off the water at the end.
