Sink Slab Sectional Elevation CAD Detail Sunk Slab Section Plan

The sink slab sectional elevation CAD drawing presents a detailed construction section of a wash basin integrated sunk slab system used in modern residential and commercial bathrooms. The drawing explains slab depression of 200mm to 300mm below finished floor level to accommodate plumbing lines, waste pipes and drainage fittings. It clearly shows wash basin placement, bottle trap connection, and 600mm drainage routing for efficient water flow. The structural slab detailing helps engineers coordinate pipe concealment within floor thickness while maintaining proper slope and waterproofing layers for long-term durability and maintenance access. This CAD detail further provides precise reference for architects, civil engineers and interior designers to execute accurate bathroom slab planning.
