When Lois and I have traveled around China and Japan the last few years, we were impressed with the range of bathroom facilities, from hole-in-the-floor "squatters" to hi-tech toilets with all kinds of built-in gizmos. Boing Boing points to a collection of "scary bathroom interfaces of India", starting with this one that features an electric water-heating element in the shower head.
Years ago, when I was traveling for Nabisco, I came across the same sort of (potentially) shocking set-up in Barquisimeto, Venezuela. Makes for quick showers. (If I remember right, that room also came with smoking mosquito coils instead of screens, as well.)
