Square three-hole vessel sink with oval bowl
Free CAD block from the Toilets, sinks, bidets and urinals library (102 blocks), drawn 1:1.
About this block
Square three-hole vessel sink with oval bowl, drawn in plan, front and side elevation, each view as drawn in the original library file. It measures 21½" wide, 19" deep and 8" high (54 cm × 49 cm × 20 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 Toilets, sinks, bidets and urinals library: 102 blocks drawn to one standard, each one available on its own.
In practice
Where it goes
A square vessel sink in plan with an oval bowl inside and three faucet holes along the back edge, for vanity layouts in hotel bathrooms, spa suites and apartment bathrooms. Draw it on the counter outline with the holes at the wall, and reuse it on the plumbing plan for the faucet layout.
Clearances to leave
The 21½ in (54 cm) square needs a 30 in (75 cm) module rather than the 28 in (70 cm) minimum, with 8 in (20 cm) between rims for a pair. Depth of 19 in (48 cm) needs a 22 in (55 cm) counter, so with 24 in (60 cm) in front the vanity zone reaches 45 in (115 cm).
Pairs with
In plan, place it in a hotel suite with the Large two-person bathtub with corner lever mixer beyond the vanity; the elevations show the thin rim, the shallow oval bowl and the P-trap.
Common questions
What are the dimensions of this block?
It measures 21½" | 54 cm wide by 19" | 49 cm deep. The drawing is 1:1, full size, so it inserts at the right size in metric and in imperial drawings.
Is there a 3D model of this block?
Yes. A 3D model built from this block's drawings, 18½" wide, 21" deep and 8½" high, is free to download in STEP, DXF 3D, OBJ, GLB, 3MF and STL. It is a closed part, so it also prints at 1:50 or 1:100 for a scale model.
File formats, AutoCAD versions and units are explained on the formats page; every file is free for personal and commercial work under the license.

- Toilet and bidet: center line at least 15" from a wall or fixture, 18" recommended.
- Clear floor in front of each fixture: 21" minimum, 2' 6" recommended.
- Sink rim at 2' 7" to 2' 11"; a double vanity needs about 2' 11" between faucets.
- For a wheelchair, plan a 4' 11" turning circle clear of fixtures.
- Keep the door swing at least 2" clear of every fixture, 4" recommended; in a small bathroom the door can open outward or slide.
