The other day, I had a delightfully long bath and did not let the water out of the tub at the end of it. There’s gotta be a use for that water, despite not being connected to a grey-water recovery system, where wash water can be reused for other purposes (laundry, for instance) or watering the terrain.
Of course, then I get the No Doubt “Bathwater” song stuck in my head.

Here are things you can do with your old bath water before you pull that plug:

  • While it’s still warm, if you are so ambitious, you can mop the floor. Just add vinegar.
  • You can wait and mop the floor another time, by adding a blast of hot water to the mop bucket.
  • You can wait until it is cool, and then water your plants with it. You can even dunk your plants for bottom-feeding if you let out all but 2 inches of the tub.
  • You technically could transfer it by bucket to a top-loading washing machine and do a load of laundry.
  • You can also flush the toilet with it. The flush happens because of the sudden influx of water – it doesn’t matter if the influx comes from the toilet tank or from a bucket.

All of these measures protect fresh water that you take from the tap that has been treated for drinking, and conserve the amount of water your home uses. If your home is on a water meter, it’ll save you a few gallons over the long run – even if baths do not use that much more water than a non-army veteran’s shower.
