Plenty of people are repulsed by the thought of using a public toilet. After all, the doorknobs, toilet seats, flush knobs, faucets and towel dispensers are hotbeds of bacteria, aren’t they? Fortunately, more and more of these facilities are being automated. Instead of turning a faucet on and off by hand or pushing the button of a soap dispenser with your finger, all you have to do is wave your hand in front of it. The sensors inside the devices can detect motion. Flush knobs and towel dispensers can be automated in a similar manner, which is great for hygiene. What about the toilet seats? Various studies have shown that these are actually among the cleanest components in a sanitary facility. In fact, the average public toilet seat contains fewer bacteria than your cutting board at home or the handle of your handbag.
