Using Your Bathtub for Emergency Water Storage

It doesn’t take much to make your local water supply undrinkable; in fact, boil orders and even do-not-drink orders are pretty common occurrences during a natural disaster. That’s why you need to take emergency water storage seriously.

During most disasters, water is going to be one of your top priorities. If you haven’t started stockpiling water, you need to get on it soon – it’s literally is a matter of life or death!

Converting Your Bathtub into an Emergency Water Storage Container

A bathtub is the perfect setup to quickly add some last-minute water to your emergency stockpile. While I would never rely on this as my primary means of water, I do think it’s a great option to supplement your supply, and should be something you do the moment things start to go bad.

If you have warning, or suspect your water supply may become compromised, you need to kick your bathtub storage plans into gear.

Commercial Bathtub Water Storage Systems

While you can simply turn on the tap and fill the tub, I advise buying a commercial storage kit like the waterBOB – it’s a lot safer and it will keep your water free from contamination.

WaterBOB Bathtub Water Storage Container

The waterBOB is made from heavy duty food grade plastic and can hold up to 100 gallons of water. The system is incredibly easy to use; just place the liner in any standard bathtub, attach the fill sock to the faucet and fill the WaterBOB to capacity. When you need the water, just use the included siphon pump to dispense the water into a jug.

Remember, water should be on the top of your emergency preparedness list. At minimum, you need to stockpile two weeks’ worth of emergency water. 1 Gallon Per Person, Per Day.

  1. I have one of these and gave many away for Christmas. I took a small piece of PVC pipe and wrapped a few feet of gorilla tape to it and put in the box so you won’t have to take the time to go get it, or hold the filler to the tub spout while you fill up other pots or…
    Set an alarm or make sure you check it so it doesn’t over flow though.

  2. Don’t forget the water heater.
    Turn off the water at the main and flip off the breaker/Turn of the gas to the heater.
    Open the hot water spigot in a sink to avoid vacuum.
    Open the relief valve at the bottom of the water heater into a container.
    My water heater has fifty gallons. 30 to 50 gallons is the usual for water heaters.
    Over a month of clean water for one person.
