"Vanity Units" refer to the additional features or upgrades in a product that enhance its appearance or prestige rather than its functionality. For example, in the world of real estate, a home might have a luxurious swimming pool or a high-end kitchen that serves more to impress guests than to improve daily living. These units often appeal to buyers' desires for status and aesthetics. In the tech industry, vanity units can be seen in products like smartphones that boast sleek designs or exclusive colors. While these features may attract attention, they often come at a higher price without significantly improving the device's performance. Ultimately, vanity units cater to our desire for luxury and style.
