Compact one-piece toilet with D-shaped trap opening
Free CAD block from the WC toilets library (114 blocks), drawn 1:1.
About this block
Compact one-piece toilet with D-shaped trap opening, drawn in plan, front and side elevation, the front and side elevations projected from its 3D model with hidden lines removed. It measures 13½" wide, 24" deep and 20½" high (34 cm × 61 cm × 52 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 WC toilets library: 114 blocks drawn to one standard, each one available on its own.
In practice
Where it goes
One-piece toilets have the tank fused to the bowl, and at 13½ in (34 cm) wide this compact model is drawn for micro-apartments, student pods, yachts and prefabricated bathroom units where width is the scarce dimension. Set it tight to the rear wall on the layout; the D-shaped trap opening shows inside the bowl and helps orient it on the drainage plan.
Clearances to leave
Width of 13½ in (34 cm) lets the toilet fit a 30 in (76 cm) slot between a shower and a wall, the 15 in (38 cm) centerline minimum on both sides. The 24 in (61 cm) depth still needs 24 in (60 cm) clear ahead of the rim, so the pod must be at least 48 in (121 cm) deep.
Pairs with
Combine with the Compact oval bathtub with deck-mounted mixer and seat ledge in a micro-apartment bathroom and the Round vessel sink with single-hole rear faucet tab on a shallow shelf. A pale single-color pod interior keeps the small room calm.
Common questions
What are the dimensions of this block?
It measures 13½" | 34 cm wide by 24" | 61 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, 13½" wide, 2' 0" deep and 20½" 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.
