The smallest room known to man is the Dutch bathroom, making even the elves claustrophobic. No much room is available for you to turn around or sit down. Certain things are unique to Dutch toilets, and these will include the lack of windows or any form of ventilation. An air freshener will be installed in the toilet bowl, and an extra spray will be offered to compensate for the lack of air circulation. Birthday reminders are a bizarre addition to these toilets. Apart from all these features, the Dutch toilet also includes the inspection shelf. Flushes are designed as a chain, rope, or string, or a push panel, foot pedal, or a button on the top of the toilet.
