Filling a bathtub uses a fixed volume of water. Reducing the flow rate has no impact on the amount of water used for a bath. Consequently there are few conservation measures directed at bathtub use.
Below are some tips to maximize efficiency in your bathtub:
- Only fill the bathtub as much as you need. Bathing babies, small children and pets requires much less water.
- Make sure that your bathtub drain plug doesn’t leak. Replace the plug or plug washer if necessary.
- Don’t overfill only to force the unneeded water into the overflow drain.
- In a drought, don’t let the used bathtub water go down the drain! Reuse bath water outdoors on your landscape.
- Bathtub water may not be useful water on all types of landscape as high concentrations of phosphates, nitrates and boron from soap may harm sensitive plant types such as citrus.
