Overview

• The guidelines note that bathrooms’ warm, humid environments foster biofilm formation and pathogen growth in overlooked fixtures.
• Regular vinegar cleaning of shower heads is advised to remove biofilms that can harbor Legionella and Mycobacteria and reduce inhalation risks.
• Damp towels and bath mats should be changed at least every three days and fully dried between uses to prevent bacterial and mold proliferation.
• Toilet flush buttons and toothbrush holders are flagged as reservoirs for fecal bacteria and residual water respectively, underscoring the need for frequent disinfection.
