Legionnaires’ disease is a serious type of pneumonia caused by Legionella bacteria, which can thrive in household water systems, including showers. To prevent Legionnaires’ disease in the shower, it’s crucial to control the growth of these bacteria by maintaining your water system properly. This involves regular cleaning, maintaining water temperature, and ensuring proper water flow.
What is Legionnaires’ Disease?
Legionnaires’ disease is a severe form of pneumonia caused by inhaling small droplets of water containing Legionella bacteria. This bacterium thrives in warm water environments, such as hot tubs, cooling towers, and plumbing systems. Symptoms include cough, fever, chills, and muscle aches, often appearing 2-10 days after exposure.
How Does Legionella Grow in Showers?
Legionella bacteria can grow in showers due to:
- Stagnant Water: Bacteria thrive in stagnant water, which can occur if showers are not used frequently.
- Warm Temperatures: Water temperatures between 68°F and 122°F (20°C to 50°C) provide an ideal environment for Legionella.
- Biofilm Formation: Showers can develop biofilm, a slimy layer that protects bacteria and aids their growth.
How to Prevent Legionnaires’ Disease in the Shower
1. Maintain Water Temperature
- Keep Hot Water Hot: Ensure your water heater is set to at least 140°F (60°C) to kill bacteria.
- Avoid Tepid Water: Use anti-scald devices to prevent burns while maintaining high water temperatures.
2. Regularly Clean and Disinfect
- Clean Showerheads: Remove and clean showerheads every three months. Soak them in a solution of vinegar and water to remove mineral deposits and bacteria.
- Disinfect Pipes: Periodically flush pipes with a disinfectant solution to kill bacteria.
3. Ensure Proper Water Flow
- Use Showers Regularly: Run showers at least once a week to prevent water stagnation.
- Flush Unused Showers: If a shower has been unused for a while, run hot water through it for several minutes before use.
4. Install Water Filters
- Use Certified Filters: Install point-of-use filters certified to remove Legionella bacteria, especially in homes with vulnerable individuals.
5. Regular Plumbing Maintenance
- Inspect Plumbing: Regularly check for leaks or corrosion in pipes that can harbor bacteria.
- Professional Assessment: Have a professional inspect your water system annually to ensure it is free from Legionella risks.
Practical Example: Implementing Preventive Measures
Consider a household where showers are used infrequently, such as a vacation home. Implementing a schedule to run water weekly, maintaining water heater temperatures, and regularly cleaning showerheads can significantly reduce the risk of Legionella growth. This proactive approach ensures safety and peace of mind.

You cannot see, taste, or smell Legionella in water. Testing by a professional is necessary to detect its presence in your water system.
Is it safe to use a shower filter to prevent Legionnaires’ disease?
Yes, using a certified shower filter can help reduce the risk of Legionella by filtering out bacteria. Ensure the filter is maintained and replaced as recommended.
Can Legionnaires’ disease be treated?
Yes, Legionnaires’ disease can be treated with antibiotics, but early diagnosis and treatment are crucial for recovery. Always seek medical attention if symptoms arise after potential exposure.
What are the symptoms of Legionnaires’ disease?
Symptoms include cough, fever, chills, muscle aches, and headache. They usually develop 2-10 days after exposure to contaminated water droplets.
How often should showerheads be cleaned to prevent Legionella?
Showerheads should be cleaned every three months to prevent biofilm buildup and bacterial growth.
Conclusion
Preventing Legionnaires’ disease in the shower involves maintaining proper water temperatures, regular cleaning, and ensuring good water flow. By following these steps and staying informed, you can significantly reduce the risk of Legionella growth in your home.
