Soap scum on the rocks anyone?


A lot of times when I have asked my friends and family about their preps, when it comes to water storage they almost always have the same answer.  Well, I have a few bottles of water stored and I can always just fill up the tub.

This is a great idea… until you think about it.  The bath tub is where you go to wash away dirt from the day’s adventures… not exactly the first place I would choose to drink from in a survival situation.  I’ve searched for different ways to effectively turn my bath tub into a storage container for water and unfortunately none of them worked very well.

I placed a tarp in my tub and while it shielded the water from the base of the tub it wasn’t completely sterile and allowed contaminants to fall into the tub from the top (dog hair, dust, etc.).

I was speaking to one of my fellow preppers and he introduced me to the WaterBOB.  It’s a neat tool that works basically like a large scale version of a hydration bladder found in your typical Camelbak pack. After seeing the WaterBoB in action at a self-reliance tradeshow, I just had to give it a shot. Here is what I found.


Compact and light- the box that this comes in takes up barely any space and can be kept under the sink

Fits almost any standard tub; you may have issues with round tubs or ones that are extra deep

High capacity- depending on the size of your tub, it can hold up to 100 gallons of water (this is enough for one person to survive for over 30 days on 3 gallons of water, or for 4 people to survive on 1 gallon for 25 days)

Sealable- the top has a screw on cap that can be placed on it to keep fresh water in it for up to a month

It comes with a syphon to quickly and easily get the water into a more accessible container


Not portable- this is something that you would only use in a bug in situation. If you are forced to leave, you would then be at the mercy of how much water you could carry

Seemingly a onetime use – it looks as though this item would be next to impossible to completely dry out after its initial use (If you have any ideas on how to dry it please let me know)

Cheaply made syphon – this syphon is the same type I can get from harbor freight or some other store.  I’ve used these in my warehouse and have never found them reliable in the long term

Bottom line

At only around $30.00,I find the WaterBoB well worth having; it doesn’t take up much space at all, and when it comes to survival, 100 gallons of clean, safe, drinking water can make a world of difference.  This of course only matters if your plan is to Bug-In.

    Just use the water in the tub for washing things and not for drinking. Buy your water to drink and water purification tablets to make the water drinkable. Good Luck.

    First, it is important that the bathtub be scrubbed before putting in the WaterBob! Also, put some type of cloth over the drain. Filling one is a small learning process, but very doable. After filling, I placed towels over it to shield from sun (and our cats!). I filled one during hurricane Irene and afterwards, pumped the water into 5 gallon containers in order to not waste it. To reuse, I hung it upside down with clothes pins and after it drained, I used a hair dryer to finish the drying process. Folded and put away for future use!

    I will suggest you obtain a water pasteurization indicator for $20 since water can be rendered potable by pasteurizing it at 145 degrees for 6 minutes. Do a Google search for water pasteurization to get the details. In my experience stored water gets skunky over time especially if stored in plastic. The Red Cross emergency water put up by Anheuser Busch and Miller in sealed cans also gets skunky. A pack of coffee filters from Dollar Tree will filter your water before you pasteurize it.

    There is now a same type bag that is made to go into a wheelbarrow
    Available at ACE and other similar stores.. Apx $20-25
    Works well

    We have one of these, have not used it yet. In our neck of the woods (desert, halfway between Phoenix & Tucson) likely not to have the time to fill it. Any power outage here would be pretty sudden, not like being in a major storm area. The good news is we have our own well and 1500 gallon storage tank. Neighbors have a 250 gallon water tank on a small trailer, which on my advice they keep full and chlorinated, 8 drops to the gallon. They aren’t terribly expensive here.

    Thinking about building a container for it in the pickup if we have to BO. Will fill when we have time and find source.

    The Global Sun Oven I have just ordered comes with a water pasteurization meter…$289 at PatriotStock

    Getg a waterbed! Great for an apartment. Rinse it out first. Put in a little clorox if you wish.

    A guess. What about using a clean vacuum cleaner
    to dry out WATERBOB.
