Best Water Storage Containers for a House Compared

The best water storage containers for a home are the ones that fit the house you actually have. A family of four needs about 56 gallons for two weeks at a gallon per person per day — the figure the CDC and FEMA both plan around. The four containers below reach that number four different ways: a cheap 7-gallon cube you buy eight of, a 5-gallon stackable kit, one big barrel in the corner of the garage, and a small brick that hides in closets. Which one wins depends on your floor space, your back, and whether you will really rotate water twice a year. Run your own household through our water storage calculator first; the container math below uses the same 56-gallon target.

Seven points cover all four containers, because each one wins somewhere different — the score says how close it is, not which shape your house needs.

What does a two-week supply actually cost in each system?

Most comparisons price one container and stop. A house does not need one container; it needs about 56 gallons. Priced as systems — every container it takes to reach that target, with the accessories each system truly needs — the order changes, and the barrel stops looking expensive and starts looking obvious. Scores above follow our published rubric: evidence 30, cost 25, owner experience 25, fit for an ordinary home 20.

As systems: eight Aqua-Tainers — sold in 2-packs at $53.74 — total $214.96. Two Saratoga kits total $329.90 for 60 gallons, spigots and preserver included. The Augason drum is $139.99, about $2.55 a gallon for the vessel itself, with the pump, bung wrench, and treatment still to buy before it is a finished system. Sixteen WaterBricks are two 8-packs at $188 each — $376 total — before you buy a single spigot, because the spigot is sold separately. The WaterBrick gap narrows when you price packs instead of single bricks. It does not close.

A stored gallon costs $2.55 in the barrel and $6.71 in bricks. The difference buys where the water can live in your house — not better water.

Why does the Reliance Aqua-Tainer win for most houses?

The owner record behind it is broad: 4.6 stars across 548 Amazon ratings on the 2-pack listing, and the same 4.6 across 1,844 reviews at Walmart for the single container. Praise repeats around value and the spigot’s stay-on flow for filling pots and bottles. The complaints repeat too, and they are specific: the spigot and vent cap are where leaks start, a minority of owners report cap threads cracking when overtightened, and the thin walls dent if a full container is dropped — one independent test program failed it on drop and crush where heavier jugs passed. Treat it as furniture, not luggage: fill it where it will live, because at about 60 pounds full, nobody in the house is carrying it far.

Buy it if: you have floor space for a row of cubes and want the lowest cost per gallon. Skip it if: you planned to stack filled containers — see the stacking section below before you do.

When are the Saratoga Farms stackables the smarter buy?

Owners rate the Saratoga stackables 4.5 stars across 987 Amazon ratings. The stories that repeat are the use case itself: a Texas owner who bought twenty jugs before a freeze and carried one at a time indoors, reporting tight lids and fresh-tasting water months later; owners switching from grocery-store gallon jugs that cracked at six months. The recurring complaint is emptying: the jug shape leaves water behind, and a stacked jug cannot be drained where it sits — you unstack, pour, restack. Plan the bottom row as the last row you use.

Buy it if: your storage is a closet or garage wall and you want spigots and preserver handled in one purchase. Skip it if: the budget is the constraint — the Aqua-Tainer stores the same water for roughly half the money.

Who should just buy the 55-gallon barrel?

Owners rate the drum 4.6 stars across 690 Amazon ratings. Praise centers on the drum arriving clean and sealing tight. The honest complaints are about living with a barrel rather than this brand: there is no spigot, so every glass of water comes through whatever pump you add — fine for filling a pitcher, tedious for washing hands — and a new drum carries a factory smell that wants a rinse-and-bleach wash before the first fill. Also settle the location before you fill it. At roughly 480 pounds full, the barrel’s first home is its permanent home, and it should sit somewhere cool and shaded, off bare concrete if you can manage a pallet or boards.

Buy it if: you have the corner and want the lowest cost per gallon of any vessel here, and you are willing to add the pump and wrench that finish the job. Skip it if: you rent, move often, or would need the water upstairs.

When does the WaterBrick earn its price?

Now the costs, stated plainly. Bricks are sold in packs, not singles: the 8-pack is $188 today, about $23.50 a brick and $6.71 a gallon — roughly twice the Aqua-Tainer’s cost per gallon — and the ventless spigot that makes a brick pleasant to pour from is a separate purchase. The owner record on the 8-pack listing is respectable: 4.5 stars across 688 Amazon ratings. Independent reviewers who tested bricks hands-on praise the durability and the stacking, and the complaint that follows the product everywhere is the gasket: seat the lid’s gasket carefully or a brick stored on its side can weep.

Buy it if: small, scattered spaces are what you have and 30-pound units are what your household can move. Skip it if: you have room for cubes or a barrel — you will pay about twice as much per gallon to solve a space problem you do not have.

Can you stack water containers when they are full?

It depends on the container, and getting this wrong is how a closet ends up flooded. The Saratoga Farms jugs and WaterBricks are built to stack filled — flat, interlocking shapes, within the makers’ height guidance. The Reliance Aqua-Tainer is not: Reliance rates it stackable when empty only, and owners who stacked filled Aqua-Tainers two high have reported the bottom unit leaking. Round barrels do not stack at all. If a roundup tells you the Aqua-Tainer “stacks,” it is repeating the box copy without the qualifier that matters.

Which full container can one person actually carry?

The WaterBrick, at about 30 pounds, is the only unit here most adults can carry comfortably. A full Saratoga jug is about 42 pounds — a two-handed, short-distance carry. A full Aqua-Tainer is about 60 pounds, which is a lift-and-shuffle for most people and a two-person job for many. The barrel, at about 480 pounds, does not move. Fill everything where it will live; the carry question is really about rotation day, when containers come to the sink one at a time.

How long can stored water sit before you rotate it?

Water does not expire, but home-filled containers should be dumped and refilled about every six months — the CDC’s guidance — or every 6 to 12 months by the Red Cross’s. Water preserver, included in the Saratoga kit and the Augason kit, is the makers’ route to stretching that interval, with claims up to five years. Read that as a claim, not a measurement we can verify from reviews. The workload choice is real either way: untreated water in Aqua-Tainers or WaterBricks means a rotation chore twice a year; treated water in the kits means trusting the treatment and marking the date on the container either way.

What are the honest caveats?

Three. First, every plastic container here degrades in sunlight — Reliance prints the warning on the Aqua-Tainer itself: prolonged direct sun makes the plastic brittle and leak-prone. Store water cool, dark, and off bare concrete, away from gasoline and pesticides, whose vapors can pass through plastic over time. Second, never store drinking water in a used drum of unknown history or in milk and juice jugs, which cannot be cleaned well enough and are not built to last; the barrel above is a new, food-grade drum, and that word “new” is doing real work. Third, leave headspace if a container might freeze — water expands about 9 percent, and a brim-full jug in a cold garage can split. Fill to about 90 percent where winters bite.

Frequently asked questions

How much water should I store for emergencies?

Plan on one gallon per person per day for drinking, cooking, and basic hygiene. Three days is the minimum officials suggest; two weeks is the sturdier target. For a family of four, two weeks is 56 gallons — the target every system in this comparison is priced against.

How long can you store water before it goes bad?

Water itself does not go bad, but home-filled containers should be emptied and refilled about every six months for taste and safety. Water preserver products claim to stretch storage to as long as five years. Either way, write the fill date on the container so the rotation actually happens.

Do I need to treat tap water before storing it?

City tap water is already treated with chlorine, so most households can store it as it comes from the faucet. Well water, or water you want extra insurance on, can be treated with about eight drops of plain, unscented household bleach (around 6 percent) per gallon, then left to sit before sealing.

What is the best container for long-term water storage?

For most houses, the Reliance Aqua-Tainer at about $3.84 a gallon, stored where it will not be stacked full or left in sun. If your space is a wall of closet, the Saratoga Farms stackables earn their higher price. If you have a garage corner, one 55-gallon barrel kit is the cheapest finished system of all.

Can I stack water containers when they are full?

Only the ones built for it. Saratoga Farms jugs and WaterBricks stack filled within their makers’ height limits. The Reliance Aqua-Tainer stacks empty only — Reliance says so, and owners who stacked them full report leaks. A round barrel never stacks. When in doubt, assume a container stacks empty until the maker says otherwise in writing.

Will stored water freeze and crack the container?

It can. Water expands roughly 9 percent as it freezes, and a container filled to the brim has nowhere for that expansion to go. In garages and sheds that drop below freezing, fill to about 90 percent and leave the headspace. A container that survives winter is also easier to carry in spring.

Which one should you choose?

Choose the Aqua-Tainer if your house has floor space and your budget has limits — eight cubes, about $215 all-in, is the two-week answer for most families. Choose the Saratoga Farms kit if your storage is vertical and you want spigots and preserver settled in the same box. Choose the Augason barrel if you have a garage corner and want the lowest cost per gallon of any vessel here, plus a pump and a wrench to finish it. Choose WaterBricks if you live in an apartment, your storage is scattered, and a 30-pound unit is what can actually be moved around your home — and go in knowing you are paying for the fit, at about twice the cost per gallon. Whichever shape you pick, size it with the water storage calculator so the gallons match your household and your climate, and see the rest of this shelf on the Water hub.
