What is the minimum combined area, in square feet, of a mop sink?

The minimum combined area of a mop sink is established to ensure that the sink meets health and hygiene standards for cleaning tasks in commercial and residential settings. A mop sink needs to be adequately sized to hold enough water and accommodate the needs for effective cleaning of mops, tools, and similar equipment.

In many plumbing codes, including the Omaha Plumbing Code, the minimum area required for a mop sink is often specified as 4 square feet. This size provides enough space to operate safely without splashing water outside the sink and allows for adequate drainage and cleaning. The 4 square feet area is considered sufficient to handle typical cleaning tasks associated with mop sinks, catering to the needs of facilities that require cleanliness, such as restaurants, schools, and office buildings.

Other options present larger minimum areas, but they exceed the standard requirements set forth in the code. By adhering to the specified minimum area, the plumbing design stays compliant with regulations and ensures functional efficiency.
