Rounded Square Basin with Broad Corner Curves
Broad curved corners occupy much of D400’s top perimeter, leaving short straight sections along the side middles. This rounded square basin with broad corner curves keeps equal outside spans while preserving those straight sections instead of becoming a circular outline. The smooth exterior bends inward toward a narrower flat lower boundary in the side elevation. A thin plain rim surrounds one continuous washing bowl, with a single central floor opening shown in the plan. The source shows no integrated tap platform or separate overflow. White ceramic D400 is listed above counter at 450 × 450 × 140 mm overall. The 140 mm figure measures the full exterior body, not an independently published inner depth or the height of a particular bowl surface.
Shape & size
Shape and size of D400
Broad corner curves between short straight sections
The top outline stays rounded square on equal spans
The original plan gives broad corner arcs a large share of the perimeter. Four short straight side middles remain visible; the equal outside dimensions do not create a circular outline.
A smooth lower curve toward a flat boundary
The outside shell narrows below its upper walls
The side elevation shows the lower walls curving inward to a narrower flat outline. Its lower footprint is not independently dimensioned, and the curve does not establish inner bowl depth.
A plain open rim around one smooth cavity
The floor opening sits at the centre of the plan
The source shows a continuous bowl without a tap platform, partition or separate overflow. Its untextured interior surrounds one central floor opening.
