ToggleOffice restroom design standards are a crucial factor that must be prioritized in any workspace. A restroom is not just a basic necessity but also reflects the professionalism and the company’s care for its employees. Therefore, office restroom design needs to ensure quality, modernity, and convenience. So, what are those standards? Let’s explore them with Co-IDB through the article below.

The Role of Restrooms in the Workspace
For Health
Restrooms play a vital role in ensuring employee health and maintaining a clean, safe work environment. In an office where many people share the space, regular restroom cleaning helps minimize the risk of bacterial infection and mold.
A well-maintained, clean restroom not only contributes to a comfortable workspace but also demonstrates the company’s professionalism and concern for its staff.

For Mental Well-being
No one wants to work in an environment where the restroom has odors or is damp. A poorly maintained restroom with unpleasant smells can make the office feel outdated, affecting the general atmosphere and negatively impacting mood, spirit, and work performance, thereby hindering overall office productivity.

Office Restroom Design Standards Businesses Should Know
Standard Restroom Dimensions
Standard Restroom Area
The standard floor area for a restroom layout must be carefully calculated based on the number of users to ensure comfort and convenience. Typically, an office restroom area should range from 2.5m² to 3m², with a minimum height of 2.3m. Additionally, the hand-washing area needs to be spacious and airy enough for user convenience.

Standard Restroom Height
In office design standards, the floor-to-ceiling height of a restroom usually ranges from 2.3m to 2.5m. However, in high-end office spaces or public buildings, this height may be designed larger, often from 2.5m to 2.7m, to create a more spacious and airy feel. Adhering to these standard heights ensures convenience and comfort while meeting safety and aesthetic requirements.

Equipment for Rational Restroom Design
Workplace restrooms must be fully equipped to ensure convenience and meet standards for ventilation, moisture resistance, and slip resistance. To design a standard office restroom, businesses should note the following essential equipment:
-
Toilets and washbasins
-
Mirrors
-
Hot and cold water systems
-
Hand soap
-
Hand dryers and hand towels
-
Toilet paper and trash cans
-
Scented wax or deodorizing essential oils
-
Ventilation fans and lighting systems

Technical Factors in Restroom Design
Technical standards for office restroom design include two critical factors:
Electrical and Plumbing Design
Because restroom environments are frequently damp, the use of moisture-proof outlets or outlets with covers is mandatory. The installation height for electrical outlets should be at an average of 1.2m from the floor to avoid water splashes and ensure user safety.
Ventilation System Design
The ventilation system must comply with office design standards to ensure airiness and safety.
For multi-story buildings (more than 5 floors), vertical exhaust ducts for restrooms are required. Meanwhile, for low-rise buildings (under 5 floors), natural suction systems are suitable.
-
Natural Ventilation: Ventilation windows with an area of 1700cm²/WC and 1000cm²/urinal.
-
Cross-Ventilation: Ventilation windows with an area of 1000cm²/WC and 600cm²/urinal.

The ventilation system must ensure an air flow rate of 30m³/WC and 15m³/urinal, with at least 5 air changes per hour to maintain freshness.
Outdoor air intake vents should have trash screens, rodent protection, and rain protection, and should be placed away from pollution or odors. The minimum height for vents is 2m from the floor; in dusty areas, this should be above 3m.
Aesthetics in Office Restroom Design Standards
When designing office restrooms, businesses must emphasize aesthetics. The space should be arranged subtly and scientifically to be both beautiful and convenient. Using bright and fresh colors will make the space feel bright, spacious, and clean.

Additionally, lighting plays a vital role. Proper lamp placement and small window designs not only enhance beauty but also aid ventilation and odor removal. Furthermore, adding green plants or using uniquely shaped scented waxes will contribute to the aesthetic of the office restroom space.

Although the restroom is only a small part of the office environment, designing it to be clean and fully functional is essential. Ensure that the restroom provides comfort and convenience for employees, contributing to overall satisfaction and efficiency.
