Standard Fixing Dimensions for Wash Basin with Bottle Trap Layout

This detailed CAD drawing presents the standard fixing dimensions for a wash basin with a bottle trap, showing both front and side elevations. The front view highlights the wash basin height at approximately 5’-3”, the T-stop cocks alignment, the hot and cold mixer position, and the centerline for fixture installation. Measurements such as 6”-0½ from the finished floor level to pipe connections and 1’-5” bottle trap height ensure accurate placement. The drawing also includes the P-trap connection to a 4” Ø waste line and clearly marks the concealed 1½” Ø water pipe inside the wall. The detailed labelling helps installers understand the exact location of each sanitary component for error-free execution.

In the side view, the drawing illustrates the wall interface, drainage slope, bottle trap positioning, and the recommended level for the wash basin. It also shows the floor drain location with grating, ensuring proper water disposal as per sanitary design standards. The combination of hidden pipe routing, stopper arrangement, and trap connection offers complete clarity for plumbers, sanitary designers, and architects. This layout is ideal for residential and commercial washroom planning where precision in fixing dimensions is essential for long-term performance and smooth maintenance.
