In architecture, a washbasin with a floor trap is a practical and hygienic solution commonly used in bathrooms, kitchens, and utility areas to manage wastewater effectively. The washbasin serves as a fixture for washing hands, face, or other small tasks, while the floor trap — typically a U-shaped or P-shaped pipe — is installed beneath the basin to prevent foul odors and gases from escaping into the living space.
The trap retains a small amount of water, creating a seal that blocks sewer gases from entering the room. Additionally, the floor trap collects debris, preventing it from clogging the main drainage system. This setup not only enhances sanitation but also simplifies maintenance by providing easy access for cleaning and removing blockages.
Proper installation and alignment of the floor trap with the washbasin are crucial to ensure efficient drainage, minimize water stagnation, and maintain a clean, odor-free environment. The combination of a washbasin with a floor trap is a fundamental element of modern plumbing design, contributing to both functionality and comfort in architectural spaces.

Washbasin with floor trap detail drawing – 1
A washbasin with floor trap detail drawing in construction typically includes several key components, each labeled clearly to show their function and relationship. Below is a textual description of what such a drawing entails:
Washbasin:
- Shown as a top view (plan) and side view (elevation/section).
- Mounted on the wall or counter, with dimensions for width, depth, and height.
- The outlet hole for wastewater is aligned with the waste pipe.
Waste Pipe (Outlet Pipe):
- Connects the washbasin outlet to the floor trap.
- Usually a PVC or GI pipe with a diameter of 32mm to 40mm.
- Shown sloping slightly downwards (1:50 slope) to ensure smooth water flow.
Bottle Trap or P-Trap (Optional):
- Installed directly below the basin outlet to catch debris and maintain a water seal.
- Prevents odors and gases from entering the space.
- Standard diameter is around 40mm.
Floor Trap (Gully Trap or Nahni Trap):
- Installed at floor level, collecting wastewater from the basin and other nearby fixtures.
- Usually made of PVC or cast iron, with a water-sealing depth of about 50mm to 75mm.
- The trap is connected to the main drainage line, ensuring proper flow and odor control.
Grating/Cover:
- Positioned over the floor trap opening to prevent solid debris from entering.
- Often made of stainless steel or plastic, with perforations for water drainage.
Drainage Pipe:
- Runs from the floor trap to the main sewer or manhole.
- Diameter typically ranges from 75mm to 100mm, depending on the system’s capacity.
Floor Finish and Slope:
- The floor around the trap is sloped gently towards the trap (1:100 slope) to direct water efficiently.
- Materials like tiles, concrete, or stone are detailed in the drawing for flooring.
Annotations and Levels:
- The drawing includes levels for the finished floor, outlet pipe, and trap.
- Additional notes specify materials, connection details, and maintenance access.
