Which is more water-efficient: a shower or a bath? It all depends on how long you shower. A shower puts out roughly five gallons of H2O every minute; so if you take a five-minute shower, you’re using approximately 25 gallons of water. A typical bath uses about 30 gallons of water to fill up the tub. Gallon for gallon, the five-minute-or-less shower is more efficient. But if you prefer to luxuriate and linger when you clean up, the bath becomes the more water-efficient choice.
