Germ Hotspots in Shared Public Toilets that Pose a Bigger Risk than the Toilet Seats
Experts say hands, handles, and toilet plumes pose a bigger risk than the seat itself
Public toilets often have a bad reputation as germ hotspots, but are toilet seats really the main culprits behind infections? Research suggests otherwise. While bacteria and viruses are present in shared bathrooms, the greater risks usually come from dirty hands, contaminated door handles, and airborne “toilet plumes” released after flushing.
Every person sheds microbes in urine and faeces, and toilets inevitably collect bacteria and viruses. Studies have found gut bacteria such as E. coli and Enterococcus, viruses like norovirus and rotavirus, and even parasites on public toilet surfaces. Skin bacteria, including Staphylococcus aureus, sometimes resistant to antibiotics, also appear. On top of that, biofilms — layers of microbes clinging under rims and on surfaces — add to the mix.
Even so, toilet seats themselves are often less contaminated than high-touch spots like flush levers, faucet handles, and door knobs. These are touched frequently, sometimes with unwashed hands, making them far more likely to spread infections.
Flushing without a lid creates another hazard: the toilet plume. Tiny droplets containing germs can shoot nearly two metres into the air and settle on surfaces. Hand dryers can then blow these microbes around even further, especially if people don’t wash their hands properly.
So, should you worry about sitting down? For most healthy people, the risk is very low. Still, experts suggest a few precautions:
- Place a seat cover or toilet paper on the seat before use, or wipe with an alcohol-based sanitiser.
- Always close the lid before flushing, if possible, to reduce toilet plume spread.
- Wash your hands with soap and water for at least 20 seconds, and use hand sanitiser if soap isn’t available.
- Skip hand dryers in favour of paper towels.
- Avoid using your phone in the toilet and clean it regularly.
- Clean baby-changing areas before and after use.
Sitting on a relatively clean toilet seat is unlikely to make you sick. Infections are far more often picked up from poor hygiene practices. Instead of fearing the seat, focus on washing your hands, using paper towels, and keeping your phone away from bathroom bacteria.
