Which uses more water: A bath or a shower?


Which bathing option is more cost-effective if you want to save money? How do you know? It’s like comparing apples and oranges when you compare a shower to a bathtub. This is because showers are measured by their duration (how long it takes for the water to run while you’re in them), and baths are measured by how much water it takes to fill the tub (regardless of how long it takes). These are just a few factors to keep in mind when deciding which method is more efficient. Which is more efficient: the bath or the shower?

What size is your bathtub? The average person requires 36 gallons of water in order to fill a bathtub, according to the USGS Water Science School. A larger tub will require more water.

Are you sure that your tub is full to the top?

You should also consider how much water your bathtub is consuming. Filling the bathtub to its full capacity takes more water than filling it halfway, or three-quarters full.

Shower duration determines how much water is used.

What length are your showers? Is it one song or a collection of your greatest hits as you shower? The more time you spend in the shower the more water you use.

More water is used when your shower does not run.

You may also consume more if you leave the water running while you are lathering your hair or shaving. Consider this: If you were to wash your hair in the sink at the bathroom, you would turn off the water during the lathering process.

Water use can be costly if you keep repeating the process.

Do you lather for one minute, two minutes or three minutes? You’re wasting water if you only lather for three minutes while the shower runs. Then you rinse again. What is the water-friendlyness of your showerhead?

Your showerhead is another factor that can determine if your shower is wasting water. According to the USGS, an old showerhead can consume up to five gallons per minute. A low-flow showerhead uses only two gallons per minute.

You will save water if you have more shower heads.

This amazing shower has six body sprays and fixed and handheld showerheads. It also features a rain showerhead. You’re likely wasting money if you use all these bells and whistles in your shower.

You can time your showers to assess water usage.

To evaluate how much water you use, you can take a timed bath to determine how long it takes. Let’s assume it was a 5-minute shower. Next day, run the water in the bathtub and adjust the faucet to get the same water flow as in the shower. Set your timer to see if your bathtub level is reached in five minutes or less. You’re likely using more water to fill your bathtub.

If you do decide to go clean, make sure you are aware of how much water you drink.
