Round Semi Recessed Basin

A Round Semi Recessed Basin combines the exposed aesthetics of a vessel sink with the spatial efficiency of an undermount configuration. Built for 400 mm to 450 mm shallow-depth vanities, the design projects forward past the cabinetry edge, maximizing internal washing space while minimizing the required countertop footprint.

The structural body is molded from high-density vitreous china fired at 1280°C in an ISO9001-certified facility, yielding a non-porous substrate finished with a micro-smooth nano-glaze. It integrates directly into stone, quartz, or solid-surface vanity tops via silicone sealant and mechanical anchor points, serving commercial hospitality, multi-family residential, and retail supply chains requiring strict dimensional consistency.

High-Density Vitreous Body: Achieves complete vitrification at 1280°C, eliminating interior micro-cracking and moisture absorption.

Low Thermal Warpage: Casting molds and controlled cooling restrict surface warpage to within ± 1.2 mm across the 420 mm diameter for flush vanity alignment.

Chemical Resistance: Mohs 6 nano-glaze withstands commercial cleaning agents, hair dyes, and cosmetic solvents without surface degradation.

Anti-Splash Geometry: Interior walls angled at 73 degrees paired with a 165 mm depth dissipate kinetic energy from vertical faucet streams.

Countertop Protection: The exposed front apron shields the underlying vanity edge from direct water exposure in narrow cabinet layouts.

Cutout Template: Execute a CNC router cut on the countertop matching the outer radius profile plus a 2 mm tolerance using the physical paper template provided in each carton.

Support Framework: Ensure vanity framing includes internal lateral bracing rated for a 100 kg static load distributed across the basin rim.

Sealant Specification: Apply structural-grade, mildew-resistant neutral cure silicone around the perimeter contact flange.

Tightening Torque: Apply a maximum torque of 3.5 N.m when securing mounting clips or threaded bolts to prevent ceramic stress fractures.

Clearance Check: Maintain a minimum 120 mm clearance between the back rim and finished wall for faucet back-nut tightening.

Hotel Guest Rooms: Fits 450 mm shallow-depth vanities in compact layouts without reducing washing area.

Multi-Family Residential: Dimensions match modular prefabricated bathroom pods and developer apartment specs.

Commercial Restrooms: Applied in corporate and retail washrooms paired with sensor faucets.

Healthcare Facilities: Crevice-free continuous glaze profiles support infection control protocols.

Dimensional Adjustments: Mold modifications available for diameters from 380 mm to 500 mm (MOQ: 500 units per mold).

Glaze Options: Standard Gloss White, Matte White, Matte Black, and custom RAL color-matched vitreous enamels.

Logo Integration: Under-glaze ceramic decals fired at 1180°C for permanent chemical-resistant branding.

Overflow Tooling: Configurable for front, rear, or blind overflow based on regional plumbing codes.

Raw Material Screening: Ball clay and feldspar undergo particle size analysis and moisture testing prior to slip casting.

Dimensional Inspection: 100% of fired basins undergo automated CMM scanning to verify flatness, rim levelness, and drain concentricity.

Surface Defect Detection: Visual screening under 1000-lumen LED arrays for pinholes, crazing, texture flaws, or iron spots.

Load Testing: Batch destructive testing verifies vertical static load tolerance up to 150 kg on the front rim.

Leak Testing: Hydrostatic pressure testing of overflow channels and bowl holding tests confirm zero water seepage.

Individual Packaging: 5-layer corrugated master carton with 25 kg/m³ molded EPE foam rim and base locking inserts.

Palletization: ISPM 15 heat-treated wooden pallets, shrink-wrapped with edge protectors and industrial strapping.

Container Loading Capacity:
20'GP Container: 650 - 720 units

40'HQ Container: 1550 - 1680 units
