If you've ever recoiled in terror at the germs you might be subjected to when flushing your toilet, you could, uh, clean the bathroom a little more regularly... or if that's not in the cards, get yourself a new Touchless Toilet kit from Kohler, and finish your business with a motion-activated whoosh.
The $100 kit allows you to retrofit nearly any existing porcelain throne with a special battery-powered mechanism in the top tank, which activates the flush when you swipe your hand above a small motion sensor. And the best part? No need to get your creepy plumber involved — it's designed for novice DIYers, and should only take about 20 minutes.
