21-Inch Rectangular Ceramic Vessel Sink with Curved Basin Floor

The interior is shaped as a soft-curve basin, with a smoothly rounded inner surface rather than hard interior corners. The curved profile guides water toward the drain and gives the bowl a clean, contemporary look that specifiers favor for modern bathroom builds. The exterior keeps a crisp rectangular form in a glazed ceramic finish that is easy to wipe down in high-turnover settings, with finish and color options confirmed on request.

Overall dimensions are 530 mm x 430 mm x 160 mm (20.9" x 17.0" x 6.3"), where 160 mm is the overall exterior height of the basin. A single faucet hole is pre-drilled on the rear deck at Φ35 mm (1.4") to accept a standard single-hole mixer. The drain outlet measures Φ45 mm (1.8") with a Φ70 mm (2.8") seat. Because the basin has no overflow, it pairs with a free-flow, non-overflow drain rather than a standard pop-up, and drain hardware can be confirmed per order.

The basin has a wide flat rim and a single rear faucet hole, and it installs against a prepared vanity top with the rim overlapping the cutout edge. Its 530 mm x 430 mm footprint suits standard single-vanity widths, and the exact mounting method along with cutout dimensions can be confirmed against project drawings at quotation. Spec drawings are available on request for countertop layout and rough-in planning.
