Mop Basins

The sink used for mops is most commonly called a 'mop sink' or 'mop basin,' though it's also referred to as a service sink or slop sink in some regions. These fixtures are typically floor-mounted, deep-basin stainless steel units built to handle heavy water volume and daily janitorial use without staining or corroding.

Mop sinks are typically shallower, floor-mounted basins (8"-14" deep) designed specifically for bucket filling and mop rinsing, often with a splash guard and full skirt. Utility sinks are usually deeper, freestanding units on legs with a faucet included, built for general washing, laundry, and maintenance tasks beyond just mopping.

Installation involves setting the basin in its designated floor or wall location, connecting it to the drain line via the basin's drain opening (typically 3-1/2"), and securing plumbing connections for the faucet. Griffin Products provides downloadable DWG, PDF, and Revit files with exact dimensions and rough-in specs to guide contractors through proper installation.

Mop basin sizing depends on your facility's cleaning volume and closet space. Common footprints range from 20"x16" to 28"x20", with bowl depths from 8" to 14". Larger, deeper basins suit high-traffic commercial kitchens and industrial sites, while compact units fit smaller janitorial closets in offices, schools, or retail spaces.

Stainless steel is the preferred material for mop basins due to its corrosion resistance, durability, and ease of sanitation. Griffin Products manufactures mop basins from 16-gauge (standard commercial) or 14-gauge (heavy-duty) stainless steel with sanitary rolled rims, ensuring long service life in high-moisture, high-traffic janitorial environments.
