I$ a $hower is more efficient than a bath?

Unless you like your bath water to be freezing cold, a shower is probably a more efficient use of energy.  To determine if this is actually so, try this simple test to see if you are using less water by taking a shower or a bath:  When taking a shower, plug the drain, bathe as usual
When done, check the height of the water in the tub--if it is less than you normally use when bathing then a shower is the more efficient route for you!
