It depends on how much water comes out of your shower head.
Some ways to use less water are, turn off the water when you brush your teeth, take a bath instead of a shower, and do not run to much water when you do take a bath!
depends on how much you want, like i have 700 gallons.
You could use a bathroom and use hot water :)
Because to fill up a bath you need to use a lot of water, this water is more then what a typical person would use to shower (showers use less water/min then filling up the bathtube)
to drink, wash things, and to take a shower.
Shower, because you don't need the water below the surface and it is already dirty. It's like sitting in your own used dirty water so you'll be dirty anyways so why use water. If your taking a shower your using clean water and you can turn off the water when you don't need it.
millions of gallons of water
A long shower will take more water than a bath, but a bath will usually use more water than a short shower.
You could put your dog a warm cloth on him / her and quickly go outside and take a shower, if possible use hot water. Or use fire beside... :)
1/4 GAL
The amount of water saved by taking a 5-minute shower instead of a 10-minute shower depends on the flow rate of the showerhead. For example, if the showerhead has a flow rate of 2.5 gallons per minute, a 10-minute shower would use 25 gallons, while a 5-minute shower would use 12.5 gallons. Therefore, you would save approximately 12.5 gallons of water by reducing your shower time by 5 minutes.
