According to the Environmental Protection Agency, the average American takes an eight minute shower. That seems like plenty of time to get clean, but if you've ever trekked five blocks in a snowstorm, you know that a shower's purpose goes beyond good hygiene. The shower is an antidote to the cold, a standing sauna, and a place to think and make plans. So go ahead and replace that worn-out shower head. While you're at it, treat yourself to new shower curtains that amp up the style—and your mood.
