One would think that all toilets are created equal, but that is certainly not the case in Korea, where many loos are equipped with fancy gadgets to ensure you a comfortable visit to the restroom. Most common of these is the etiquette bell. This small device attached to the wall or on the side of the toilet acts as a remote control of sorts. The purpose? At the push of a button, the stall will be filled with the sounds of a flushing toilet or a cheery tune, to mask other noises commonly heard in a bathroom.
