The fact that my emerging interest in Human Factors/Ergonomics and design (see here) coincided to a large degree with me having to spend a lot of time in toilets due to colitis (see here), has meant I’ve developed a, some would say “unhealthy”, obsession fascination interest in the way toilets and bathrooms are designed. It basically means that every time I go into a toilet or a bathroom, I’m paying more attention to what’s around me than I used to. This will include observing things such as taps, sinks, doors, locks, signage, layout (pretty much everything really!), and thinking about the potential impacts, both positive and negative, that these “99% invisible” features have on aspects of life such as personal hygiene, public health, privacy, accessibility, usability, aesthetics and so on.
