What is the minimum required depth for a mop sink?

The minimum required depth for a mop sink is established to ensure that it can effectively handle the volume of water and waste generated during cleaning operations. A depth of 10 inches is adequate for allowing proper drainage and preventing splatter, which helps maintain hygiene in areas where mops are used frequently, such as kitchens and janitorial closets.

A mop sink with a depth of 10 inches provides sufficient capacity for rinsing mops, cleaning tools, and even filling cleaning buckets without risk of overflow or inadequate drainage. This requirement aligns with plumbing code guidelines that aim to promote sanitation and prevent water stagnation, which can attract pests and lead to other hygiene-related issues.

In contrast, depths that are too shallow would be insufficient for cleaning tasks, while excessively deep sinks might lead to wasted water and plumbing inefficiencies. Thus, 10 inches strikes a balance between functionality and resource conservation, making it the correct choice for the minimum depth standard for mop sinks.
