Tom Reynolds, chief executive of the Bathroom Manufacturers Association, draws attention to an often-overlooked issue in public health: toilet plume.
While a designer’s focus in creating bathroom spaces concentrates on their technical knowledge to achieve functionality and beautiful design, they will also ensure that safety and practicality are part of the brief. However, how many of us are aware of the risks of toilet plume or have even heard of the term?
Toilet plume refers to the microscopic particles and droplets released into the air when a toilet is flushed. These particles can contain various pathogens, including bacteria, viruses, and other microbes, posing a potential risk to human health. Flushing generates a turbulent flow of air and water within the toilet bowl and can cause these microorganisms to become airborne, where they may linger and settle on surrounding surfaces.
Research has demonstrated that toilet plume can transport harmful pathogens such as staphylococcus, E. coli, and even the virus responsible for COVID-19. This airborne spread is particularly concerning in public and shared bathrooms, where multiple users increase the likelihood of exposure to these pathogens.
One of the most effective measures to reduce the spread of germs is to close the toilet lid before flushing. While not 100% effective, this simple action creates a physical barrier that can significantly reduce the dispersion of airborne particles, containing them within the toilet bowl. Maintaining proper bathroom hygiene through regular cleaning and disinfecting surfaces further minimises contamination risk. Aware of the dangers, bathroom manufacturers increasingly offer antibacterial glazed coatings that make cleaning easier, helping to reduce contamination of surfaces.
Ventilation also plays a crucial role in managing the effects of toilet plume. Adequate ventilation can help dissipate airborne particles more quickly, reducing their potential to settle on surfaces or be inhaled. Designers should take note and ensure that bathrooms can be well-ventilated, whether through windows or mechanical ventilation systems.
Given the health implications, increased awareness about the risks associated with toilet plume should be high on the agenda. A public information campaign is essential to educate individuals on the importance of proper bathroom practices, but designers can also help this effort. By raising awareness and promoting preventive measures through clever product selection, incorporating ventilation into design concepts, and educating clients, reducing the transmission of illnesses linked to toilet plume is possible.
It’s time we closed the lid on this unseen health hazard.
