Yes, you can often shower when the power is out, but it depends on how your home gets water and heats it, and you need to think about safety and water supply limits.

Quick Scoop

  • If your home has city water and a gas water heater, a shower will usually still work in a power outage, at least until the hot water in the tank runs out.
  • If you rely on an electric well pump or an on‑demand electric heater, you may not have water or hot water when the power is out.
  • The biggest immediate risks are:
    • Slipping or falling in a dark bathroom.
    • Using up limited hot water you might want to save for later.

When It’s Usually Safe

  • City water + gas water heater:
    • Water pressure is supplied by municipal pumps and towers that often remain pressurized for a while during outages.
* Gas heaters can still deliver some hot water because the tank was heated before the power went out.
  • City water + electric tank water heater:
    • You can typically take a short warm shower using the hot water already stored in the tank, but it will not re‑heat until power returns.

When You Should Be Careful or Avoid It

  • Private well systems:
    • If your pump is electric, water may stop flowing as soon as the power goes out, so the shower may not work or may suddenly stop mid‑shower.
  • Tankless/on‑demand electric heaters:
    • These usually need electricity to heat water, so you’ll likely only get cold water, if any.
  • During active thunderstorms:
    • Some safety sources advise avoiding showers during lightning storms because plumbing can conduct electricity in rare but documented cases.

Practical Safety Tips

  • Use a battery lantern, flashlight, or phone light so you can see and avoid slips or stepping on anything sharp in the dark.
  • Keep electrical items (hair dryer, space heater, extension cords) away from the tub or shower area in case power suddenly comes back.
  • Take a quicker shower than usual to conserve limited hot water and avoid over‑taxing any backup power system like a generator.

Simple Rule of Thumb

  • If water still runs with good pressure, your heater isn’t fully dependent on electricity, and there’s no active lightning storm, a short, careful shower is generally considered reasonable, as long as you light the bathroom safely and watch your footing.
