Which type of lavatory is commonly used in commercial settings?

In commercial settings, the grid strainer lavatory is often favored due to its practical design and functionality. This style typically features a simple, flat surface that allows for easy cleaning and maintenance, which is essential in high-traffic environments like restaurants, offices, and public restrooms. Unlike more decorative lavatory styles, the grid strainer design prevents clogs by allowing water to flow through while catching debris, making it a reliable choice for durability and ease of use.

In contrast, other types of lavatories, such as pop-up, vessel, and drop-in lavatories, may not offer the same level of practical utility and maintenance ease that is typically required in commercial installations. For instance, vessel lavatories can be more challenging to clean due to their raised design, and drop-in lavatories may require more intensive installation efforts, which could be less desirable in a fast-paced commercial environment. Therefore, the grid strainer lavatory stands out as the most suitable option for commercial applications.
