Where must adequate lavatories be located?

Adequate lavatories must be located in or adjacent to restrooms to ensure accessibility and convenience for individuals using the facilities. This placement is critical because it allows for proper sanitation and hygiene, as lavatories are typically utilized for hand washing after using restrooms. By situating them close to restrooms, it promotes a clean environment and encourages their use, which is essential in public and private establishments to prevent the spread of germs and ensure the health of patrons and staff alike.

Having lavatories in the main waiting area, service areas, or only outside the establishment would not provide the necessary hygiene and accessibility needed for effective sanitation. Therefore, the appropriate location emphasizes the importance of health and safety standards in public facilities.
