If you're someone who likes to soak in the tub to get clean, be sure to stopper the tub as soon as you turn on the water. Trust us - we want your bath to be warm, but you'll be able to heat up the initial cold water in time before you and your rubber ducky hop in for a swim. This way, you won't have perfectly good water rushing down the drain, only to be wasted. Your savings - both in terms of water and your water bill - will be remarkable. For extra points, do this when you shower, too.
