Double bowl kitchen sink with drainer CAD block
By Sumana Kumar · Published 30 Aug 2025 · Updated 18 Apr 2026
A double bowl kitchen sink with a drainer is the classic family-kitchen wet zone: two basins for washing and rinsing, plus a ribbed draining board to one side. It is one of the most-placed kitchen blocks because the combined bowl-and-drainer footprint largely sets the length of a run, and getting it scaled correctly tells you straight away whether the sink, the window above it and the cabinets either side line up. This page gives you a free double bowl sink with drainer CAD block in DWG and DXF, drawn at true millimetre dimensions and ready to insert into AutoCAD 2004 or later — free for personal and commercial work, no signup, no watermark.
Because the drainer is part of the same unit, the block shows the full envelope you have to allow on the worktop, not just the basins. Drop it onto a plan and you can immediately see how much cabinet run the sink consumes, where the centre line falls relative to a window, and whether the drainer should sit left or right of the bowls for the way the kitchen is used.
What a double bowl sink with drainer block shows
The block draws two bowls separated by a divider, with a tap deck behind and a draining board extending to one side. In plan you see both bowl openings, the divider, the tap position and the ribbed or grooved drainer surface; the drainer is what distinguishes this block from a plain double sink and is usually drawn with parallel run-off lines so it reads clearly on a layout.
It is built as one block reference so the whole sink-and-drainer assembly moves, copies and rotates together. The two bowls, the divider, the tap and the drainer are typically on sensible sub-elements so you can mirror the unit to flip the drainer side, or freeze the drainer hatching when you want a simpler general-arrangement read.
Views and what's included
The primary view is plan, used for kitchen layouts and general arrangement drawings, showing both basins and the drainer from above. Where an elevation is supplied it shows the bowl depth below the worktop and the tap profile; the drainer reads as a flat worktop run in elevation, so the elevation is mostly about the basins and tap.
A double-with-drainer is asymmetrical because the drainer sits to one side, so orientation matters. Insert the block, then mirror it if the drainer needs to be on the other hand — for example, to drain towards the cooker side of the kitchen. Keep the tap as a separate element so you can swap a single mixer for a dual-tap arrangement from the faucet category.
Typical double bowl and drainer sizes
Use these ranges as a guide, not as fixed specs. A double bowl unit with an integral drainer commonly spans roughly 1000–1200 mm overall along the worktop, with the two bowls together occupying a large part of that and the drainer taking the remainder. Each bowl opening is usually in the region of 350–450 mm wide, and bowl depth typically runs about 150–220 mm below the worktop.
The worktop is conventionally 600 mm deep at a 900 mm finished height. Because the whole unit is long, it tends to need a 1000 mm or wider sink base cabinet, or a pair of cabinets under a continuous worktop. Check the overall length against the available run before you commit, and leave standing space at the drainer end so wet items have somewhere to go.
How to insert, scale and orient the block
The block is drawn full size in millimetres. Insert at scale 1 in a millimetre drawing, 0.001 in a metre drawing, or set INSUNITS to millimetres so AutoCAD rescales an imperial template automatically. Run INSERT or drag the DWG in from a tool palette.
Pick an insertion point you can snap reliably — a bowl centre or a corner of the rim — and rotate to align the unit with the worktop. Decide the drainer hand early: if it is wrong, MIRROR the block about the vertical centre line rather than re-inserting. Put the assembly on a sanitary-ware or plumbing layer so you can toggle it for structural versus fitted plans, and use BEDIT once if you need to tune the divider or tap and have every copy follow.
Where double bowl sinks with drainers are used
This is the default kitchen sink for family homes, larger apartments, holiday lets and house-share kitchens — anywhere two basins earn their place for washing and rinsing and a drainer is wanted for air-drying. It also suits utility rooms that double as a second prep area, and small catering kitchenettes where a separate drainer beats a worktop groove.
Place it under the window where plumbing and natural light usually dictate, then build the cooking and storage runs around it. Pair the block with the cooker, hob, dishwasher and cabinet blocks in the kitchen set, and keep everything on layered furniture and sanitary-ware so you can produce a clean plan, a fitted plan and an elevation from one drawing.

Questions
Frequently asked
How long is a double bowl sink with a drainer?+
Most run roughly 1000–1200 mm overall along the worktop, with two bowls plus a draining board. The block is drawn to true scale, so insert it and measure against your actual run rather than assuming one fixed length.
Can I flip the drainer to the other side?+
Yes. The unit is asymmetrical, so after inserting use MIRROR about the vertical centre line to move the drainer from one hand to the other. There is no need to re-insert a separate block.
Does the drainer show in elevation?+
In elevation the drainer reads as part of the flat worktop run, so the elevation mainly shows the bowl depths and the tap. The ribbed drainer surface is drawn in the plan view where it matters for layout.
Is the block free to use on client projects?+
Yes. It downloads free in DWG and, where available, DXF, with no signup, watermark or attribution, and it is cleared for commercial project use.
