The primary distinction lies in the specific functions and definitions associated with each type of basin. A sink is a broader term that refers to a plumbing fixture used in various contexts, primarily for washing, which can include food preparation, cleaning dishes, and other general uses in kitchens or utility areas. On the other hand, a lavatory is specifically designed for handwashing and personal hygiene, typically found in bathrooms. This functional focus on washing hands emphasizes the lavatory's role in hygiene, while the sink encompasses a wider variety of use cases. Understanding this distinction is crucial for plumbing professionals when designing or installing fixtures, as it informs decisions about sizing, placement, and plumbing connections needed for each application. Recognizing that sinks serve a general purpose, while lavatories have a specific use, helps clarify their placement in residential and commercial settings.
