As Winter Storm Fern barrels toward neighborhoods across the country, a surprisingly low‑tech prep step is suddenly trending: people are turning on the tap and filling their bathtubs. It looks a little odd until the power flickers, pipes freeze, and the faucets go quiet. Then that tub becomes one of the most useful “appliances” in the house.
The basic idea is simple. When a major winter system threatens to knock out electricity or water service, having a bathtub full of clean water gives homeowners a backup for flushing toilets, washing up, and even limited drinking once it is properly treated. It is cheap, fast, and, as Fern reminds everyone, often the difference between riding out a storm comfortably and scrambling once the lights go out.
Fern, frozen pipes, and why everyone is suddenly talking about bathtubs
Winter Storm Fern has people in cold‑prone states racing through their checklists, and the bathtub has moved near the top. Forecasts tied to Fern describe “extremely cold air” trailing the system, the kind that locks roads in ice and pushes infrastructure to the breaking point. In guidance shared with millions of residents, meteorologists warned that this blast could prolong dangerous travel and infrastructure problems into the following week, a scenario that has already led emergency managers to urge households to store extra water before the worst of the storm hits, including by filling tubs ahead of what has been described as one of the worst storms in decades.
That advice is landing. In coverage of Fern’s approach, homeowners have been shown running taps and stocking up on water in bathtubs and buckets, treating it as basic insurance in case pipes seize up or municipal systems falter. One report on Fern’s imminent arrival described how residents were urged to prepare for the possibility that a major issue could arise with their water supply and highlighted that people were already filling tubs in anticipation of Winter Storm Fern. The logic is straightforward: if the storm knocks out power or freezes lines, the water already in the tub is still there, ready to use.
The simple physics of frozen pipes and stalled taps
The rush to fill bathtubs is rooted in how brutally cold air treats plumbing. When temperatures plunge below about twenty degrees Fahrenheit, exposed or poorly insulated pipes can freeze solid, blocking flow and sometimes bursting outright. Reporting on recent cold snaps has underscored that when temperatures drop below that threshold, water in pipes can quickly turn to ice, leaving households without running water and forcing them to scramble for alternatives once the pipes freeze.
Experts who walk homeowners through pre‑storm prep point out that people often focus on food, flashlights, and phone chargers while forgetting the plumbing that quietly keeps daily life running. One guide to winter readiness notes that one of the things people often neglect is their pipes, even though a frozen line can instantly cut off access to clean water and create expensive damage when it thaws, which is why the checklist now routinely includes filling a bathtub as a way to remove dangerous buildup and keep water on hand before the snow hits, advice that has been shared by Jan experts.
From toilets to dishes, what that tub of water actually does for you
Once the pipes freeze or the power fails, the first surprise is often the toilet. Without pressure in the lines, tanks do not refill after a flush. That is where the bathtub stash becomes essential. Homeowners preparing for Fern have been told that if pipes freeze, they could still flush by scooping water from the tub into the toilet’s bowl or directly into the toilet’s tank as needed, a workaround that has been highlighted in coverage explaining why filling a tub can make a major difference in getting through the next storm Thank you.
Beyond flushing, that stored water can handle a lot of unglamorous but crucial tasks. People use it to wash hands, rinse dishes, sponge‑bathe kids, and keep pets watered without dipping into bottled supplies. A detailed breakdown of why tubs matter in storms notes that this reserve can be used for cleaning, basic hygiene, and even limited cooking once it is filtered or boiled, which is why guides on storm prep list multiple reasons to fill your bathtub with water before a storm. In short, it keeps the household functioning while the grid and the pipes catch up.
Why well owners and rural households lean on the tub even more
For people on private wells, the bathtub is not just a convenience, it is a lifeline. When the power goes out, the electric pump that pulls water from the ground stops instantly, leaving faucets dry even if the pipes themselves are not frozen. Emergency guidance issued ahead of Fern has been explicit that residents with private wells are encouraged to fill a bathtub or portable containers with water so they can pour it into their toilets for flushing during a power outage, a recommendation that state officials have circulated to Residents in storm‑prone areas.
That same logic shows up in community advice shared among neighbors. In one widely shared “Tip for those on well water,” a local group urged people facing accumulating ice and likely power loss to fill up their bathtub so they could use that water to flush toilets instead of wasting bottled water, with commenters chiming in about saving two liter bottles, filling washing machines, and keeping jugs on standby as backup, all framed as common‑sense steps their families have “always did” when the Tip for well water households goes out.
How official storm prep checklists turned the tub into standard gear
The bathtub trick is not just folklore passed down from grandparents, it has been folded into formal storm guidance over time. In regions used to tropical systems, emergency agencies explain that people are asked to fill their bathtubs before a severe storm because after the event, water pressure can drop or treatment plants can be compromised, leaving tap water unsafe to drink. One government FAQ spells it out clearly, noting that you are asked to fill the tub so there is a backup supply if the mains are damaged or the water is not safe to drink, advice that has been repeated in Why storm briefings.
That same thinking has migrated into winter storm playbooks. Home maintenance guides now routinely tell readers that in addition to preparing for snow and ice, they should have water on hand before the snow hits, including in bathtubs and large containers, so they are not caught off guard if pipes freeze or service is interrupted, a point that has been emphasized in advice aimed at Homeowners. The result is that filling the tub has quietly joined batteries, blankets, and canned soup on the standard pre‑storm checklist.
Hurricane hacks that work just as well in a blizzard
People who live along the Gulf and Atlantic coasts have been filling bathtubs before hurricanes for years, and many of their tricks translate neatly to Winter Storm Fern. Preparedness guides for tropical systems explain that a storm can disrupt the clean water supply by damaging mains or treatment plants, so residents are urged to store water in every available container, including tubs, before the first bands of rain arrive. One step‑by‑step guide even suggests covering the bathtub with a clean sheet or plastic to keep debris out, explaining that this simple move can help families ride out the storm a bit more comfortably.
Those same tactics make sense when snow replaces storm surge. Covering the tub keeps dust and pet hair out over several days, and pairing that stored water with a basic filter or purification tablets turns it into a more versatile resource. Preparedness writers note that ideally, households have a water purification kit or a good filter on hand so they can safely purify water that has been sitting in a tub or bucket, and they recommend filling up jugs or buckets alongside the bathtub to stretch supplies, advice that has been shared with a casual “But ideally” reminder in winter prep But ideally guides.
Power outages, heat sources, and why water belongs in the same conversation
When people think about losing power in a winter storm, their minds usually jump to heat, not water. That is understandable, but the two problems are tightly linked. Safety tips for cold snaps stress that if you have an alternate heat source such as a gas fireplace, wood‑burning stove, or fireplace, you should make sure you have enough fuel to keep it running when the power goes out, and they pair that advice with reminders to plan for water needs at the same time, since outages can affect both systems once the power goes out.
That is where the bathtub fits into a broader survival plan. Emergency checklists for winter storms in places like New Mexico and West Texas ask blunt questions: do you have enough supplies to get you through a few days, and have you thought through what happens if roads are closed and utilities are down. Those prompts are meant to nudge people into stocking not just food and blankets but also water in multiple forms, from bottled cases to a full tub, so they are not forced into risky trips or unsafe improvisations when a winter storm alert becomes a reality.
How much water to store, and how to keep it usable
Emergency planners often talk about gallons per person per day, but the bathtub offers a more intuitive benchmark. A standard tub can hold dozens of gallons, enough to cover flushing and basic hygiene for a small household for several days if they are careful. Preparedness writers suggest pairing that bulk storage with smaller containers, like jugs and buckets, so people can dip out what they need without contaminating the whole supply, a strategy that shows up in advice urging households to fill up jugs or buckets alongside the tub when a major storm is on the way, guidance echoed in winter prep pieces that start with a casual But and then get very specific.
Keeping that water usable is mostly about cleanliness and common sense. Covering the tub, using clean containers to scoop, and reserving bottled water for drinking all help stretch supplies. In some cases, people also contribute to broader water awareness efforts, logging what they see outside while they manage what is in their homes. Community science projects encourage residents to share observations about whether it is raining, snowing, or a wintery mix, explaining that with your observations, scientists can better estimate how much water falls during winter, a reminder from groups that stress how Your local experience feeds into the bigger picture.
Why this “old‑school” move keeps coming back every winter
For all the smart thermostats and weather apps in modern homes, the bathtub strategy survives because it works. Coverage of Fern and similar storms has shown that while it may seem like a waste of water to fill a tub that might never be used, that one step can make a major difference in getting through the next blast of snow and ice, especially when pipes freeze and toilets stop working, a point that has been driven home with a simple “While it may seem a waste of water” reminder in stories about how people are preparing for While Fern.
That is why the advice keeps resurfacing from so many directions at once. Home experts like Jan, emergency managers, neighbors swapping tips on social media, and storm‑season veterans all land on the same low‑tech move: before the first flakes from Fern hit the driveway, turn the tap, fill the tub, and give yourself one less thing to worry about when the wind starts howling. As one practical guide put it, one of the smartest things people can do before a snowstorm is to think about their pipes and their water, a message that has been repeated in pieces that open with Jan and end with a full bathtub quietly waiting in the bathroom.
