Description
The top-mount drop-in sink block is a front elevation drawn to scale, 21″ wide and 7⅛″ high (532 × 181 mm).
Both versions, inches and millimeters, are DWG files that open in AutoCAD 2000 or newer; insert either one at scale 1 and it lands at its real size.
For an accessible lavatory the rim sits no higher than 34″ (864 mm), with 27″ (686 mm) of knee clearance below (ADA 606). Compared with the 6 ft person beside it, it reaches below knee height.
Working outside CAD? The same drawing also comes as a DXF for other CAD programs, a PDF for printing, a PNG with a transparent background for slides and mood boards and an SVG you can edit in Illustrator, Inkscape or Figma.
Common questions
What size is the top-mount drop-in sink drawn at?
It measures 21″ wide and 7⅛″ high (532 × 181 mm) in front elevation, taken from the outer edges of the drawing. The page shows the same sizes in both units next to the drawing.
Do I need to scale the block when I insert it?
Both. cadgrid-top-mount-drop-in-sinks_in.dwg is drawn in inches (INSUNITS 1) and cadgrid-top-mount-drop-in-sinks_mm.dwg in millimeters (INSUNITS 4). Insert the one that matches your drawing at scale 1 and the block comes in at its real size.
How high should a sink be mounted?
Residential vanities are usually 32–36″ (813–914 mm) high. For an accessible sink the rim goes no higher than 34″ (864 mm) above the floor, with 27″ (686 mm) of knee space below.
Can I use this top-mount drop-in sink outside AutoCAD?
Yes. Use the DXF in other CAD programs, the PNG with its transparent background in slides, documents and mood boards, the SVG to edit it in Illustrator, Inkscape or Figma, and the PDF to print it or send it to someone without CAD.
