Long sink top with offset bowl and drainboard
Free CAD block from the Kitchen sinks library (155 blocks), drawn 1:1.
About this block
Long sink top with offset bowl and drainboard, drawn in plan, front and side elevation, all three projected from its 3D model so they match to the millimeter. It measures 5' 11" wide, 21½" deep and 13½" high (1.80 m × 55 cm × 34 cm), and it is drawn 1:1, full size, so it drops into any drawing set up in meters or in inches without rescaling.
It also comes as a 3D model built from these drawings.
From the Kitchen sinks library: 155 blocks drawn to one standard, each one available on its own.
In practice
Where it goes
At 71 in (180 cm) this is a full sink top rather than a bowl: one bowl set off-center and a long drainboard. It belongs on plans for laboratories, school art rooms, dental offices, florists and commercial kitchens, where a long run of stainless is drawn as a single unit on the floor plan.
Clearances to leave
Plan a 71 in (180 cm) run of base cabinets, or a cantilevered frame in a laboratory, and a 25 in (64 cm) countertop depth for the 21½ in (55 cm) top. The long drainboard makes a landing unnecessary on that side; keep 24 in (61 cm) beyond the bowl and 48 in (122 cm) of aisle in a teaching room.
Pairs with
Double-bowl sink with two faucets and ribbed drainboard is the shorter two-bowl top; and Wide single-bowl sink with right drainboard and upstand covers the 47 in (120 cm) case. Utensil rail with spatulas and serving spoon on the wall above keeps the elevation simple.
