The two-tap-hole semi-recessed basin bridges countertop vessel sinks and undermount basins. Projecting forward from the vanity cabinet line, it optimizes floor space in compact layouts while accommodating standard-depth furniture (350mm to 450mm).
The dual-hole configuration accommodates separate hot and cold pillar taps or a dual-handle bridge faucet setup, specified for hospitality and residential retrofits requiring individual water control or specific regional plumbing compliance.

Product Advantages
Space Efficiency: Reduces required vanity cabinet depth to 400mm, preserving primary circulation space in narrow hotel corridors and compact ensuites.
Thermal Shock Resistance: High-pressure casting and high-temperature kiln vitrification eliminate internal micro-voids, withstanding thermal fluctuations from 0 deg C to 90 deg C without structural cracking.
Vitrified Glaze Hardness: Glaze thickness maintained at 0.6mm to 0.9mm with a Mohs hardness rating of 6, resisting scratching from abrasive cleaners and metal objects.
Flatness Tolerance Control: Bottom mounting surface ground flat within +/- 1.0mm, ensuring secure sealing against stone, solid surface, or laminate countertops.
Installation Requirements
Cabinet Clearance: Vanity top cutout profile must match the supplied CAD DXF template. Internal framing must clear the front bowl drop.
Countertop Support: Compatible with solid surface (Corian), natural stone, quartz, and moisture-resistant MDF/plywood countertops.
Fixing Method: Mechanical fixing brackets or structural neutral-cure silicone sealant applied along the perimeter flange. Load distribution relies on the countertop ledge.
Plumbing Clearances: Verify wall-to-waste and wall-to-supply-line centerlines prior to countertop fabrication to prevent interference between dual faucet shanks and internal bulkheads.
Applications
Hotel & Resort Hospitality: Standardized specification for guest room bathroom renovations requiring durable, easy-to-maintain fixtures with dual-tap aesthetics.
Multi-Family Residential: High-rise apartment complexes utilizing space-saving semi-recessed footprints to maximize usable bathroom floor area.
Healthcare & Assisted Living: Public or patient washrooms requiring ergonomic front access and dual-control faucet accessibility.
Commercial Office Restrooms: Corporate facilities enduring high daily user cycles.
OEM & ODM Customization
Mold Development: In-house CNC pattern making and plaster mold casting enable custom bowl geometries, radii adjustments, and modified tap-hole positions within 20 working days.
Logo Integration: Under-glaze ceramic decal firing (fused at 1100 deg C) or laser-etched vitreous branding applied per client specification.
Glaze Color Matching: Custom Pantone or RAL ceramic glaze matching available for large-volume hospitality projects.
Packaging Customization: Tailored drop-test-certified master cartons, private-label pallet layouts, and barcoded UPC/EAN label generation.
Quality Control
Raw Material Inspection: Incoming clay batches undergo moisture content, particle size distribution, and plasticity testing before slip preparation.
Green Body Verification: Laser inspection of cast bodies to detect shrinkage cracks, pinholes, or distortion prior to glazing.
Glaze Thickness & Adhesion Test: Electromagnetic thickness gauges verify uniform glaze application; dye-penetrant testing confirms absence of micro-fissures.
Load & Drainage Testing: Finished basins undergo static load testing (supporting 150 kg applied to the front rim for 30 minutes) and 100% flow-rate evacuation checks.
Packaging & Export
Individual Packaging: 5-layer corrugated export master carton with 25kg/m3 high-density molded EPS corner protectors custom-molded to basin contours.
ISTA 2A Drop Test Compliance: Carton packaging validated to withstand vertical and diagonal drop impacts simulating standard LTL and courier handling.
Palletization: Fumigation-free heat-treated wooden pallets (ISPM 15 compliant) or heavy-duty plastic pallets, secured with high-tensile stretch film and strapping bands.
Logistics Loading: Optimized 40-foot high cube (40HQ) and 20-foot container (20GP) configurations to maximize volumetric efficiency.
FAQ
Q: What is the standard minimum order quantity (MOQ) for custom OEM molds?
A: MOQ starts at 300 units per mold design for custom dimensions or non-standard tap-hole configurations. Standard catalog items support mixed-container orders.
Q: Can the two tap holes be spaced at custom distances?
A: Yes. While standard spacing is 100mm or 200mm centers, CNC tooling allows custom spacing configurations for specific regional faucet sets based on engineering drawing approval.
Q: What documentation is provided for customs clearance and building compliance?
A: Each shipment includes commercial invoices, packing lists, Bills of Lading, Certificate of Origin (Form A/CO), and third-party laboratory test certificates (CE/cUPC) corresponding to the production batch.
Q: How do you handle shipping breakage claims?
A: All container shipments follow strict international drop-test standards. In the event of transit damage exceeding the agreed allowance threshold, photographic evidence submitted within 7 days of port arrival triggers immediate replacement dispatch in the subsequent order shipment.
Q: What is the standard production lead time for bulk orders?
A: Standard production runs require 25 to 30 days upon receipt of deposit and technical drawing confirmation. Peak seasonal volumes may require 35 d
