How much water does a bath waste?

Taking a bath typically uses more water than taking a shower. The amount of water used in a bath can vary depending on the size of the bathtub and the depth of the water. On average, a standard-sized bathtub can hold around 40 gallons of water. If the bathtub is filled halfway, it can use around 20 gallons of water. In comparison, a 10-minute shower with an average flow rate of 2.5 gallons per minute can use around 25 gallons of water.

To conserve water, it's generally recommended to take shorter showers instead of baths whenever possible. If you do choose to take a bath, you can save water by filling the tub only partway or using a low-flow showerhead. You can also collect the bathwater and reuse it for watering plants or cleaning.
