I drink tons of water as does the rest of my family. Tap water, even in the best cities, still often has lots of junk in there that tastes bad and may not be that good for you either. A few years ago, we decided to get a water cooler for our house and have never looked back. Although it may seem a bit weird to have an office-grade cooler in your home, I highly recommend it if you drink lots of water. A cooler is a much cheaper solution than buying liter-sized bottles of water and does not produce tons of empty plastic bottles.
I like Sparkletts best: good taste, reliable delivery, healthy product, and a super-friendly and reliable staff who gets us our water on-time.

I'm completely down with the idea of putting a cooler in the home, but I do wish they'd make them a little cuter.
