Floor Access and Drainage

Proper drainage and accessible floor infrastructure are essential for the safe and hygienic operation of service stop toilet facilities.

Purpose: Provide access to concealed services such as plumbing, drainage, and electrical systems for maintenance and inspections.

Location: Typically positioned along service corridors or near high-use fittings (e.g., behind vanities or toilet rows).

Design: Should be flush with floor level, slip-resistant, and made from durable, corrosion-resistant materials (e.g., stainless steel or aluminium).

Specification: Must comply with load-bearing requirements for commercial environments and be easy to open with appropriate tools.

Design: A sloped floor is essential to direct water to floor drains, especially in areas with high splash risk (e.g., around urinals, basins, and accessible shower facilities).

Drain Types: Linear or point drains with removable grates are commonly used. Trapped gullies are recommended to prevent odour backflow.
Materials: Drain covers should be anti-slip, easy to clean, and vandal-resistant.

Maintenance Access: Drains must be positioned for easy access via hatches or removable grilles to allow regular cleaning and prevent blockages.

Additional Considerations:
- drainage components to comply with local building and health regulations.
- usage of waterproof, chemical-resistant floor finishes to support hygiene and longevity.
- in accessible WCs, consideration to be given to recessed channels or concealed drainage to reduce trip hazards.
