Apartment Emergency · Stay
When the toilet stops working.
Nobody wants to think about this one. But when the water goes out, the sewer backs up, or the building plumbing fails, sanitation becomes urgent within hours. In a house, you might dig a latrine. In an apartment, you have no yard, no septic system, and a hallway full of neighbors with the same problem. This page covers what actually works indoors, in a small space, with supplies you can store under a sink.
Why sanitation cannot wait
Disease spreads faster than any disaster.
Historically, more people die from sanitation failure after a disaster than from the disaster itself. Diarrheal disease, norovirus, and other fecal-oral infections spread rapidly when human waste is not contained, when handwashing breaks down, or when waste contaminates water supplies. In a shared apartment building, the risk compounds: shared hallways, shared trash areas, and shared plumbing mean one household's sanitation failure can affect the entire floor.
Water outage
No water means no flushing, no handwashing at the sink, and no cleaning. In a building with electric water pumps, a power outage can cause a water outage even when the municipal supply is fine.
Sewer backup
A building sewer line failure can push waste back up through drains on lower floors. Flushing when the sewer is backed up makes the problem worse. If you hear gurgling from drains or see water rising in the toilet without flushing, stop using the plumbing and report it immediately.
Frozen pipes
In a winter storm, building pipes can freeze and burst, particularly in older construction. Sprinkler pipes, supply lines, and drain lines are all vulnerable. The result is either no water or uncontrolled water, neither of which leaves you with a working toilet.
Building pump failure
High-rise buildings use electric pumps to push water to upper floors. When the power goes out and the building has no backup generator covering the pumps, upper-floor residents lose water pressure first and completely.
The emergency toilet
Your own toilet, without the plumbing.
The most practical emergency toilet for an apartment is the one you already have. Your existing toilet bowl, with the water turned off and the bowl lined with bags, becomes a stable, comfortable, familiar commode that works without any plumbing at all. This method is recommended by the Washington State Department of Health and multiple emergency management agencies as the primary approach for apartment residents.
How to set it up
Do not flush if the sewer is backed up.
If you see water rising in the toilet, hear gurgling from drains, or smell sewage coming from floor drains or bathtub drains, the building sewer line may be compromised. Flushing adds volume to a system that cannot drain, which can push sewage into your unit and your neighbors' units. Switch to the bag-and-bucket method immediately and report the problem to building management.
Alternative
The five-gallon bucket. Simple and effective.
If the toilet bowl itself is inaccessible, damaged, or overflowing, a standard 5-gallon bucket from any hardware store serves the same function. This is the method recommended by the Regional Disaster Preparedness Organization (RDPO) and Oregon State University Extension Service for households without access to outdoor latrines.
Setup
- Line the bucket with two nested heavy-duty garbage bags, same as the toilet method.
- A snap-on toilet seat lid designed for 5-gallon buckets costs roughly $10 to $15 at hardware stores and makes the bucket significantly more comfortable and stable. If you do not have one, the bucket rim works, but is less comfortable for extended use.
- Add absorbent material after each use. Kitty litter is the most commonly recommended option. A 10-pound bag of non-clumping kitty litter costs a few dollars and lasts one person roughly a week of emergency use.
- When the bag is roughly half full, tie it closed, remove it, and replace with a fresh bag. A half-full bag is still manageable. A full one is heavy, unwieldy, and risks tearing.
- Keep the bucket in the bathroom with the door closed. Ventilation helps: crack a window if possible. The bathroom is already designed for this purpose, and keeping the waste in one room limits odor exposure in the rest of the apartment.
A portable camping toilet is another option if you already own one or want to invest ahead of time. They work on the same principle (bag or cassette containment) but are more comfortable for multi-day use. Any model rated for indoor use is appropriate.
Hygiene without running water
Handwashing is not optional. It is the most important thing on this page.
The CDC is direct on this point: feces from people is an important source of germs including Salmonella, E. coli, and norovirus that cause diarrheal disease. Washing hands with soap and water for at least 20 seconds after every toilet use is one of the most effective barriers against the fecal-oral spread of disease. In a plumbing emergency, when the sink does not work, handwashing takes more effort but remains non-negotiable.
Three methods, in order of effectiveness
Soap and water from your stored supply
Pour bottled water or pre-boiled water over your hands into a basin while you lather with regular soap for 20 seconds. This is the full CDC-recommended handwash. A small basin or pot to catch the rinse water keeps the bathroom manageable. Dispose of the gray water down a drain if the drain is still functional, or bag it separately.
Alcohol-based hand sanitizer
Use a hand sanitizer containing at least 60 percent alcohol. Apply enough to cover all surfaces of your hands and rub until completely dry, at least 15 to 20 seconds. The CDC notes that hand sanitizer is less effective than soap and water, does not work well when hands are visibly dirty, and is not effective against norovirus. Use it when soap and water are truly unavailable, not as a routine substitute.
Sanitizing wipes
If you have neither water nor sanitizer, antiseptic wipes are the last resort. They are better than nothing but substantially less effective than either of the methods above. Wipe all surfaces of both hands, between fingers, and under nails. Wash properly as soon as any water becomes available.
When to wash.
After every toilet use. After handling waste bags. After changing diapers. Before preparing food. Before eating. After touching any surface that may have been contaminated. After caring for someone who is ill. This list is not optional even when water is scarce. Budget your stored water to include handwashing, not just drinking.
Surface disinfection
Keeping your bathroom from becoming a hazard.
When you are using a bag-and-bucket toilet, the bathroom surfaces, the toilet seat, the bucket rim, and any area where bags are handled need regular disinfection. Ordinary household chlorine bleach is the standard disinfectant for emergency sanitation, per Seattle Emergency Management and Loma Linda University guidance.
Bleach disinfection
- Disinfecting solution: 1 part household chlorine bleach to 10 parts water. Mix in a spray bottle or basin. Use regular unscented liquid bleach (typically 5.25 to 8.25 percent sodium hypochlorite). Do not use color-safe bleach or bleach with added fragrances or cleaners.
- Wipe down the toilet seat, bucket rim, and surrounding floor after each bag change. Also wipe the door handle, light switch, and any surface touched with gloved hands during waste handling.
- Pour a small amount of the bleach solution into each waste bag after use to reduce odor and begin disinfecting the contents. This is recommended by Seattle Emergency Management and Loma Linda University.
- Wear rubber or vinyl gloves when handling waste bags. Wash or sanitize hands after removing gloves. Gloves protect against direct contact but are not a substitute for handwashing.
The apartment-specific problem
Where do you put the waste when there is no outside?
A homeowner can store sealed waste bags in a garage, shed, or outdoor bin. An apartment resident may have none of these. This is one of the most uncomfortable realities of apartment sanitation during an extended plumbing outage, and it needs a plan before the situation arises.
Balcony storage bin
If you have a balcony, a heavy-duty bin with a tight-fitting lid stored in a corner is the best apartment option. The outdoor air reduces odor impact inside the unit. Use a bin designed to resist animals and weather. Weigh the lid down if wind is a concern.
Bathroom bathtub
The bathtub is a contained, non-porous surface with a drain. Place a lined bin or bucket in the tub and keep the bathroom door closed. The tub catches any leaks and is easy to disinfect afterward. This is the best indoor option when no balcony is available.
Never use shared spaces without coordination
Do not place waste in hallways, shared trash rooms, or building dumpsters unless building management or local emergency officials have specifically designated a collection point and procedure. In a building-wide plumbing failure, management may set up a centralized waste collection system. Follow their instructions when available.
Odor management
In a small apartment, odor becomes its own emergency.
In a house, you can open windows on all sides and keep waste far from living areas. In a 600-square-foot apartment, the distance from the bathroom to the kitchen might be 15 feet. Odor management is not a comfort issue. It is a livability issue that affects whether people can eat, sleep, and function in the space.
What helps
- Kitty litter after every use. The single most effective odor control measure. Non-clumping litter absorbs moisture and reduces odor more than shredded paper or sawdust.
- Change bags frequently. Do not wait until the bag is full. Once daily for a single person, more often for a household. Fresh bags with fresh absorbent material dramatically reduce ambient odor.
- Bleach solution in each closed bag. A small amount of the 1:10 bleach solution poured into the bag before sealing helps disinfect the contents and reduces bacterial odor production.
- Keep the bathroom door closed. A towel along the bottom of the door provides additional odor containment.
- Open a bathroom window if possible. Natural ventilation is the most effective air-quality tool you have when mechanical ventilation is down.
Supplies
Everything you need fits under the bathroom sink.
The complete emergency sanitation kit costs roughly $15 to $20 and takes up less space than a box of tissues. Buy it now and put it under the sink. You will not want to shop for these items when the plumbing has already failed.
The apartment sanitation kit
Heavy-duty garbage bags (3-5 mil, box of 20+)
Non-clumping kitty litter (10 lb bag)
Household chlorine bleach (1 quart)
Spray bottle (for bleach solution)
Rubber or vinyl gloves (box of 10+)
Hand sanitizer (60%+ alcohol, 12 oz+)
Bar soap (2 bars)
Toilet paper (extra 4-pack)
Antiseptic wipes (1 pack)
Twist ties or zip ties (for sealing bags)
Optional but useful: a 5-gallon bucket with a snap-on toilet seat lid ($10-$15 at any hardware store). This serves as both the backup toilet and the waste storage container. If you have a balcony, a second bin with a tight-fitting lid for sealed waste bags.
Household considerations
Children, elderly household members, and dignity.
Children
Small children may be frightened or confused by the change in routine. Explain what is happening in simple terms. Toddlers and potty-training children can continue to use a small child-sized toilet or the modified adult toilet with help. Soiled diapers go into the same heavy-duty bags as other waste, sealed and stored the same way. Keep an extra supply of diapers in your emergency supplies, sized for your child. Handwashing after every diaper change is critical.
Elderly household members or people with mobility limitations
The existing toilet is the best option because it is already at the right height and has a stable seat. The bucket method may be too low or too unstable for someone with difficulty sitting down or standing up. If the toilet bowl is unusable, a bedside commode (available at medical supply stores) can be lined with bags the same way. Consider this investment ahead of time if anyone in the household has mobility concerns.
Dignity matters
Emergency sanitation is inherently uncomfortable. Maintaining privacy (the bathroom door stays closed, the system is contained and clean, odor is managed) is not a luxury. It is part of keeping a household functional and emotionally stable during an already stressful event. Taking this seriously before the emergency is what makes dignity possible during it.
