Maybe I'm missing something here, but I don't see the need for a beer specifically designed for drinking while taking a shower. Your typical shower takes what, 10 Minutes? If you can't go ten minutes without a beer, you're probably not showering much anyway.
“Your typical shower takes what, 10 Minutes?”
Depends a lot on who you’re with.
