Best Emergency Water Storage for Home: Barrels, Bathtub Bladders and Stackable Containers

Best overall water container for most homes

Sportsman's Warehouse: $26.99, in stock, ships to home · Holds: 7 gal · Cost per gallon: $3.86 · Full weight: about 58 lb of water · Owner rating: 4.1 from 15 reviews

If you buy one kind of container, make it a rigid 7-gallon jug, and the Reliance Jumbo-Tainer 2.0 is the one we'd start with. Seven gallons covers one person for a week at the CDC's 1-gallon-a-day minimum. Full, it's light enough for most adults to move, and it's built to be refilled for years. Reliance lists it as FDA approved and BPA free, with a leak-proof hideaway spigot that stores inside the cap and two handles for pouring and tie-down. It measures 15.3 x 8.5 x 18 inches, and Reliance calls the slim shape good for fitting under shelves and counters.

It's the most-reviewed water container at Sportsman's. Owners like the dual handles; one bought six because his older Reliance jugs were "still going strong after 5 years of water storage with no leakage," and he weighed one full at 61.2 pounds. Others are blunt about the problems. One owner had two units leak when laid on their side, another says two of three cracked after a couple of years, and a third advises you to "test the spigot for leaks upon purchase." Fill it, set it on its side for a day, and check before you put it in the closet.

It isn't made to stack when full (owners mention this), so a closet of them takes floor space. Want water you can pump while the jug stands upright? Reliance's Anti-Gravity Water Pump ($14.99 at Sportsman's) replaces the spigot on most of its rigid containers.

Best barrel for long-term storage in small spaces

Sportsman's Warehouse: $64.99, in stock, ships to home · Holds: 15 gal · Cost per gallon: $4.33 · Full weight: 130 lb (listing) · Owner rating: 4.5 from 10 reviews

A barrel is how you get past a few days of water without a wall of jugs. Most people picture a 55-gallon drum, but those weigh well over 400 pounds full and need a spot where they'll sit for good. A 15-gallon barrel is the compromise: enough water for one person for about two weeks at the listing's ration (2 quarts for drinking and 2 for light cooking and sanitation), in a footprint that fits a closet or garage corner. Sportsman's lists it as heavy-duty, thick food-grade polyethylene, BPA free, in dark blue that "restricts light and helps control growth of harmful algae and bacteria."

Owners rate it well: 7 of 10 Sportsman's reviews are five stars. "Well made," says one, and another has his barrels "filled and stored. No leaks." One shopper who wanted a 55-gallon found that "2 15's work quite well," and reminds buyers to sanitize with a bleach solution before filling and to add a preservative for multi-year storage.

Plan for two things. First, it has no spigot: an owner bought a pump because pouring a 130-pound barrel isn't realistic, so budget for a siphon or drum pump. Second, the handles are for the empty barrel. One owner warns, "Don't try to lift it by the handle when it is full of water it will come off." Fill it where it will live.

Best bathtub bladder for a storm that's on the way

Maker list price: $39.00 (waterbob.com showed it out of stock on November 10, 2026; check Amazon for current availability) · Holds: up to 100 gal · Cost per gallon: about $0.39 to $0.65 · Reuse: one-time use (maker)

This is the product behind this month's search spike: "bathtub bladder water storage" is up 1,900% on Google. The idea is simple. When a hurricane or ice storm is a day or two out, you lay the WaterBOB liner in your bathtub, attach its fill sock to the faucet and fill it. WaterBOB says filling takes about 20 to 30 minutes and the liner holds up to 100 gallons, though it adds that most standard tubs hold about 60 to 70. That's more water than every other pick here combined, for about the price of one jug.

WaterBOB says the liner is heavy-duty 10 mil food-grade LLDPE plastic, and a siphon pump is included to fill pitchers and jugs. Why not just fill the tub? An open tub collects dust, soap residue and whatever the dog drops in. The sealed liner keeps the water separate. WaterBOB says the water stays fresh for up to 16 weeks, depending on humidity and temperature, if you keep sunlight off it with a towel or sheet. For well water it recommends treating the water right after filling.

Know the limits. It's designed for one-time use, so it's a short-notice tool, not long-term storage. It only works if your taps still run when you fill it, which is why it belongs with a few sealed jugs rather than in place of them. And stock is thin: WaterBOB's own site was sold out on November 10, and rival AquaPod's kits were too. If you live in hurricane or ice-storm country, buy one before the forecast turns. We couldn't confirm Amazon's stock or price, so the price here is WaterBOB's list price.

Best stackable water storage for apartments and closets

Maker list price: $54.50 for a 2-pack (on backorder at waterbrick.org and sold out at Survival Frog on November 10, 2026; check Amazon for current availability) · Holds: 3.5 gal each · Cost per gallon: $7.79 · Full weight: about 27 to 30 lb each (maker)

If you live in an apartment, floor space is the problem, not money. WaterBricks are 3.5-gallon blocks, 9 x 18 x 6 inches, that cross-stack like building bricks up to 4 feet high, according to the maker, so 10 of them (35 gallons) can fill a closet floor or slide under a bed. WaterBrick says the container is HDPE, the lid polypropylene and the gasket TPE, all BPA free and FDA compliant, with UV protectant.

Other things to like: each brick weighs about 27 to 30 pounds full (the maker's two pages differ), so anyone in the family can carry one, and the handle comes off for stacking. The 3¼-inch lid opening is wide enough to reach into, so a brick can store rice or beans instead of water. WaterBrick sells a spigot separately for $19.95.

The catch is price. At $7.79 per gallon, it costs about twice as much per gallon as the Jumbo-Tainer. It's also hard to get right now. The maker lists the blue 2-pack on backorder, and Survival Frog had every WaterBrick variant sold out on November 10. The price shown is WaterBrick's own list price; we couldn't confirm Amazon's stock or price.

Best budget pick (and best for a car or go-bag)

Sportsman's Warehouse: $10.99, in stock, ships to home ("only a few left" on November 10) · Holds: 5 gal · Cost per gallon: $2.20 · Empty weight: 0.65 lb · Owner rating: 3.7 from 10 reviews

For about $11, this is the cheapest way to hold 5 gallons, and empty it folds flat enough to keep in a trunk, a bug-out bag or a kitchen drawer. Reliance makes it from high-grade polyethylene, BPA free, with a leak-proof on/off spigot and a fold-down handle, and says it stays flexible in extreme cold.

Owner reviews tell you how to use it. One has had his "since late 1990's" without a crack. Others report problems over time: one says about half of his were "leaking in <18 months," and another had two crack at the corners after winter storage. One owner says he's "not sure I would store water in them for long periods." Our read: collapsibles are great for filling up when a storm is coming, carrying water home from a distribution point, or hauling water to a car or camp. For water that sits in a closet for six months, buy a rigid jug.

Stock was low on November 10. Reliance's newer Fold-A-Carrier 5 Gallon ($11.49, clear so you can see the water level, no reviews yet) and the Alexapure 5 Gallon Collapsible ($16.99 at My Patriot Supply) are the alternatives.

Best sealed, grab-and-go drinking water

My Patriot Supply: $39.99 for 64 pouches, available November 10, 2026 · Holds: about 2.1 gal (64 x 4.227 fl oz) · Cost per gallon: $18.95 · Shelf life: up to 5 years (maker)

Water you store yourself has to be swapped out every six months, according to both the CDC and Ready.gov. Commercially sealed water lasts longer and needs no thought, which is why the CDC calls unopened bottled water "the safest and most reliable source of water in an emergency." Ready Hour's pouches are the prepper version of that. Each one holds 4.227 ounces of reverse-osmosis purified water in a BPA-free, four-layer pouch that's 6 x 4 x ½ inches. Ready Hour rates them for up to five years, and a case of 64 packs into a 13 x 9⅞ x 6¾-inch box.

It's the top seller in My Patriot Supply's water containers collection when sorted by best-selling. Pouches are good for the places a jug won't go: a go-bag, each car, a desk drawer at work, a kid's school kit.

Don't treat it as your main supply, though. At $18.95 per gallon it's the most expensive water here, and a case is roughly two gallons, about two days of the CDC minimum for one person. Use it alongside the jugs and barrels, not instead of them.

Best add-on: keep stored water fresh longer

My Patriot Supply: $19.99, available November 10, 2026 · Treats: up to 60 gal per pack (listing) · Cost per gallon treated: about $0.33 · Type: two-part chlorine dioxide

This isn't a container, but it belongs in the same order as one. Aquamira's two-part kit is a chlorine dioxide treatment (Part A) plus a phosphoric acid activator (Part B). You pre-mix equal parts in a cup and add it to stored water. The listing says one pack treats up to 60 gallons and gives the doses: 1 teaspoon of each part per 5 gallons, 2 tablespoons of each per 30 gallons, and 4 tablespoons of each per 60 gallons. It carries EPA Reg. No. 71766-1, it's made in the USA, and it's the top seller in My Patriot Supply's water treatment collection.

Two honest notes. My Patriot Supply's copy says the treatment helps keep stored water from spoiling but doesn't give a storage time, so follow the CDC's six-month rotation unless the product label says otherwise. And the listing says to clean and disinfect the container and lid before treating. That matches the CDC's steps below.

If you want a way to make questionable water drinkable after your stored water runs out, add Potable Aqua purification tablets ($9.99 for 50 at Sportsman's) or a filter from our water filter guide. Ready.gov notes that boiling is the safest treatment method if you have the fuel.
