To see fascinating sink design, visit Thai restaurants in New York City. (Maybe other places, too; I just haven’t been elsewhere.) You’ll see everything from tilted rubber slabs to, well, I don’t know what to call it when the faucet spout is a room-length horizontal bamboo (with a perforated copper pipe inside) that rains straight down, and the “sink” is pebbles on the floor behind a waist-high wall of glass. Amazingly creative ideas going on. So in fact, yup, sinks can be re-thought.
