I’m always thinking about ways of making my bathroom more spa-like. Sometimes I dream of adding a bigger tub. Other times, I wonder what it would be like to have my own sauna. If I lived somewhere that only got a few hours of sunlight each day, I might even consider adding a tanning bed like Republican Vice Presidential candidate Sarah Palin. These options are well out of my budget right now, but fortunately there are more affordable ways to give your bath the feel of a spa.
