depends on how much you want, like i have 700 gallons.
Average shower heads use about 2 gpm, so a 5 minute shower is 10 gallons.
How big is the shower?
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)
It depends on how much water comes out of your shower head.
1 gallon
millions of gallons of water
It depends how long you are in the shower for. A quick shower is more efficient than a bath. A power shower for a long period ( i.e. 10 mins ) may not be more efficient than a bath, depending uponm how much water it uses.Also, some people share bath water, making it ultimately more efficient than showering.It depends on how long you are in the shower for, if it is just you that has to wash, and whether you have a power shower or not.Generally however, for single persons having a quick wash, they are more efficient. If there is more than 1 person, a bath (all use the same water)If just one then a quick shower. Long showers (20min+) are worse than baths, even for just one person.
1/4 GAL
A shower head would use between 60 to 75 gallons for a 30 minute shower.
You can make the whole shower experience a game. For example, who can get to the shower first, use the water toy guns to play a shooting game with your child. Use dye to dye the water in the water gun. Tell your child he will get a treat at the end if he/she behaves in the shower.
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!
It depends on the shower heads, bath heads, and the person. If you take a long shower, and use little water for a bath, bath is better. If you use a lot of water for a bath and take short showers with water saving heads, a shower would be better.
switch off lights when your not using them only boil as much water that you need don't use too much water in the shower switch off the PC when not in use
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.
