What is Service Sink?
A service sink is a deep and sturdy floor-mounted sink used for cleaning equipment, filling buckets, and routine janitorial work.
Definition
Purpose
The main purpose of a service sink is to provide a dedicated place for maintenance personnel to fill mop buckets, rinse cleaning tools, dispose of dirty water, and wash equipment without using regular restroom or kitchen sinks.
By separating cleaning activities from sanitary fixtures, service sinks help improve hygiene, reduce cross-contamination, and support efficient building maintenance. They are built to withstand heavy use and exposure to cleaning chemicals.
Examples of Use
- Before mopping office floors, a janitor fills a mop bucket at the service sink.
- Maintenance staff empty dirty mop water into the service sink after completing cleaning tasks.
- Hospital housekeeping teams rinse mops and cleaning tools in dedicated service sinks between shifts.
- Warehouse staff use a service sink to wash maintenance equipment and refill cleaning buckets.
Notes
- Usually has a large basin for buckets, mops, and larger cleaning tools.
- Commonly installed as a floor-mounted sink for convenient access to a bucket and drainage.
- Frequently found in utility rooms, janitor closets, and maintenance areas.
- Ideal for janitorial applications in commercial, industrial, institutional, and healthcare facilities.
