Can You Shower When the Power Is Out?

Yes, in most Tampa homes you can shower when the power is out. If your house is on city or county water, the water keeps flowing because the utility runs its treatment plants and pump stations on backup power. Whether that water is hot is a separate question, and it comes down to what kind of water heater you have. Homes on a private well are the big exception: the well pump runs on electricity, so once the power goes, the water stops shortly after.

That question comes up every time a storm knocks out power across Tampa Bay, and hurricane season runs through November 30. Here is how to figure out what your home can do before the lights go out, plus the safety issues that matter more than a hot shower.

Two Things Decide Whether You Can Shower Without Power

Every home comes down to the same two factors:

1. Where your water comes from. City water arrives under pressure from the utility. Well water depends on a pump in your own yard.
2. How your water heater makes heat. Some gas water heaters work with no electricity at all. Electric models and most modern gas units do not.

Answer those two and you know exactly what to expect when the power goes out.

City Water Usually Keeps Flowing During an Outage

If you pay a water bill to the City of Tampa or Hillsborough County, your water pressure comes from the utility's system, not from anything inside your house. You can shower with no power, flush, and wash your hands as normal in most outages.

Big storms can still interrupt that system. After Hurricane Milton in October 2024, power loss in Temple Terrace caused low water pressure and a boil water notice, and Hillsborough County asked residents to use water only for drinking and sanitation because outages were straining the pumping system and raising the risk of sewage backing up into homes. So even with city water, keep an eye on local alerts after a storm.

Well Water Stops When the Well Pump Loses Power

Many homes in rural Hillsborough and Pasco counties run on private wells. If that is you, the answer to "can you shower when the power is out with a well" is usually no, at least not for long. The well pump needs electricity to push water into the house. Your pressure tank holds a small reserve, which may give you a quick rinse or a few flushes, and then the taps go dry.

Well owners have two realistic options during hurricane season:

• Store water before the storm. Fill bathtubs and large containers for flushing and washing, and keep separate drinking water.
• Plan for backup power. Well pumps typically draw more power than a small portable generator can handle, and connecting a generator to your home's wiring safely requires a transfer switch installed by a licensed electrician.

Your Water Heater Decides Whether the Water Is Hot

Yes, a power outage affects hot water in most homes, but not all of them. Here is how each common type of water heater behaves when the electricity goes out:

Water heater type	Hot water during an outage?	Why
Electric tank	Only what is already stored	The heating elements shut off, but the tank stays warm for a while.
Gas tank with a standing pilot light	Yes	The pilot and gas valve work without electricity.
Gas tank with electronic ignition or a power vent	Only what is already stored	The igniter, controls, or exhaust fan need electricity to fire the burner.
Electric tankless	No	It heats water on demand with electricity and stores none.
Gas tankless	No, without backup power	The fan, ignition, and circuit board all run on electricity.
Heat pump (hybrid)	Only what is already stored	The compressor and backup elements are electric.
Solar water heater	Depends on the system	Systems that circulate water with an electric pump stop; passive systems keep working.

Not sure which one you have? Look at the label on the tank or check whether there is a small window showing a pilot flame near the bottom of a gas unit. Our team can also identify it for you during a routine water heater service visit.

How Long Hot Water Lasts Without Power

A tank water heater is basically an insulated thermos. Once the power cuts out, the water inside starts cooling slowly, and how long it stays comfortable depends on the size of the tank, how well it is insulated, and how much hot water your household draws. Every hot shower pulls cold water into the tank, which cools what is left faster.

To make stored hot water go further:

• Keep showers short and stagger them so the tank is not drained all at once.
• Skip hot water for dishes and hand washing until everyone has showered.
• Use the warmest water first rather than saving it, since it only cools over time.

And if the hot water runs out, a cold shower is still perfectly safe on city water. In a Tampa September, it may even feel good.

When Showering During a Power Outage Is Not Safe

Having water does not always mean it is a good time to shower. These are the situations where you should wait.

Lightning Is Still in the Area

Hurricanes and the storms around them bring plenty of lightning, and Florida already sees more of it than almost anywhere in the country. A lightning strike on or near a house can travel through plumbing, including homes with plastic pipes, because the water itself conducts electricity. Health experts at the Cleveland Clinic recommend waiting at least 30 minutes after the last thunder before you shower or bathe.

The Bathroom Is Dark

Wet tile and no lights is how people get hurt. Use a battery lantern or flashlight instead of candles, which are a fire risk and easy to knock over in a small, wet room.

A Boil Water Notice Is in Effect

Boil water notices are common after hurricanes. You can usually still shower, but the CDC advises that you avoid swallowing any water while bathing and consider giving babies and young children a sponge bath instead. Always follow the specific instructions in your utility's notice.

Your Water Heater Was Under Floodwater

Storm surge and street flooding regularly reach garages, which is where many Tampa water heaters live. A water heater that sat in floodwater should not be used, and a gas unit should not be relit, until a professional has inspected it. Flooded gas controls and electrical parts can fail in dangerous ways.

A Generator Is Running Too Close to the House

If you are running a generator to power a well pump or water heater, it has to stay outside. The CDC says generators must be placed at least 20 feet away from doors, windows, and vents, and never in a garage, even with the door open.

Why You Should Fill the Bathtub Before a Hurricane

Filling the bathtub before a storm is one of the oldest pieces of Florida hurricane advice, and it still holds up. That water is not for drinking. It is your backup supply for everything else:

• Flushing toilets. Pouring a bucket of water into the bowl will flush it, even with no water coming into the tank.
• Washing up. A basin and a washcloth go a long way when the taps are off.
• Cleaning. Rinsing dishes, wiping surfaces, and cleaning up after pets.

This matters most for homes on a well, but city water customers benefit too if a water main breaks or pressure drops. Before you fill the tub, make sure the drain stopper holds water overnight, since many slowly leak. If there are young children in the home, keep the bathroom door closed while the tub is full.

Go Easy on the Drains After a Storm

Wastewater in much of Tampa Bay moves through lift stations, which are pumps that push sewage through the system. When those pumps lose power, the pipes can back up. That is why the county asks residents to cut back on water use after major storms. Showering, laundry, and running the dishwasher all send water down the drain, so keep usage light until officials give the all clear.

The same goes for homes on septic. A conventional gravity system keeps working without power, but systems with a pump or an aerobic treatment unit need electricity. Too much water going in while the pump is off can push wastewater back toward the house.

If you notice gurgling drains or a sewage smell after a storm, stop using water and call a plumber. Our sewer line team can find out whether the problem is in your line or on the city side.

A Quick Pre-Storm Checklist for Water and Showers

• Find out which type of water heater you have and whether it needs electricity.
• Know where your main water shutoff and your water heater's shutoff are.
• Fill bathtubs and large containers for flushing and washing.
• Store drinking water separately.
• If you are on a well, plan how you will get water if the pump is down for days.
• Sign up for alerts from your water utility so you hear about boil water notices right away.

When to Call a Plumber After the Power Comes Back

Most homes go right back to normal when the power returns. Call a licensed plumber if you notice any of the following:

• Your water heater sat in floodwater.
• You smell gas near a gas water heater or anywhere else in the home. Leave the house first and call your gas company from outside.
• Hot water does not return after power has been back for several hours.
• Your pilot light will not stay lit.
• Drains are backing up, gurgling, or smell like sewage.
• Your water pressure stays low after the utility says service is normal.

Frequently Asked Questions

Can you shower when the power is out?

Yes, if your home is on city or county water. The utility keeps water pressure up with its own backup power. Whether the water is hot depends on your water heater. Homes on private wells usually lose water once the well pump stops.

Can you shower when the power is out with a well?

Only briefly. A well pump needs electricity, so you only have what is left in the pressure tank. For longer outages, you need stored water or a properly installed backup power source.

Does a power outage affect hot water?

In most homes, yes. Electric, tankless, heat pump, and most newer gas water heaters stop heating without electricity. Gas tank models with a standing pilot light keep working. Tank models still hold warm water for a while after the power goes out.

Is it safe to shower during a power outage?

Usually, as long as there is no lightning in the area, you have a safe light source, your water heater was not flooded, and you follow any boil water notice. Wait at least 30 minutes after the last thunder before showering.

Do you need power to take a shower?

Not on city water. Water pressure comes from the utility, not your home's electricity. You only need power for hot water from most water heaters, and for well pumps.

Why fill the bathtub with water during a power outage?

Bathtub water is a backup for flushing toilets, washing, and cleaning if your water supply stops or a well pump loses power. Pouring a bucket into the toilet bowl flushes it. Do not use it for drinking.

Can you shower during a boil water notice?

Generally, yes, but the CDC advises avoiding swallowing any water while you bathe and giving babies and young children sponge baths. Follow the specific instructions from your water utility.
