While it may appear like baths use up more water than showers, that may not be the case. There are two factors to consider: (1) water pressure/efficiency of your shower head, and (2) length of shower time.
The following is a quick summary from the book, "Is It Really Green", by Georgina Wilson-Powell.
- The average tub holds 36 gallons (136L)
- The average shower pumps 5 gallons (19L) of water per minute (unless you have a water-saving shower head)
- The math = If you shower for more than 7 minutes, you are using more water than a bath tub (the average person showers for 9+ minutes)
We recommend soaking in your bath for 30+ minutes and we do not recommend filling up the entire way (more like half of your bathtub), so you're definitely getting a lot out of your water usage. For those who do not have bathtubs, we are coming out with foot soaks in the near future!
