It is not safe to shower during a thunderstorm. Lightning can strike a house and travel through its plumbing, including metal or plastic pipes, potentially causing an electric shock if you are showering. Water is a good conductor of electricity, so lightning can travel through the water and pipes to strike a person from the showerhead or faucet. Experts and health authorities recommend avoiding any water-related activities, such as showering, bathing, washing dishes, or washing hands during a thunderstorm. The safest practice is to refrain from showering and using plumbing for at least 30 minutes after the last thunder is heard to ensure the storm has passed.

Why Showering is Unsafe

• Lightning can follow plumbing as a path of least resistance to the ground.
• Water conducts electricity, increasing the risk of electrical shock during a shower.
• This risk exists even with plastic pipes, though it may be lower than with metal pipes.

Safety Recommendations During Thunderstorms

• Avoid all contact with plumbing and running water.
• Do not use electrical devices plugged into outlets.
• Stay inside, away from windows and electrical equipment.
• Wait at least 30 minutes after hearing the last thunder before showering.
