Oval Semi Recessed Basin

The Oval Semi-Recessed Basin bridges vessel ergonomics with undermount integration. Engineered for standard 450mm–500mm vanity depths, the basin body projects forward past the cabinet face, maximizing internal bowl volume while reducing required countertop depth.

Tailored for commercial hospitality architects, vanity manufacturers, and plumbing distributors, this configuration resolves spatial constraints in luxury bathrooms without compromising user reach. Manufactured via high-pressure casting and fired in tunnel kilns exceeding 1200°C, the vitreous body delivers structural density for high-frequency commercial use.

Flatness Tolerance: Bottom-mating flange flatness controlled within ± 0.5mm, ensuring secure silicone bonding and zero rocking against stone or solid-surface countertops.

Low Porosity Body: Fired at 1280°C for 22 hours, eliminating micro-voids to prevent structural water seepage and thermal shock cracking.

Chemical Resistance: Nano-fired glaze creates a surface tension barrier rated Class A against acids, alkalis, and household organic solvents (ISO 10545-13).

Drainage Geometry: Deep-draw oval radius (R140mm) combined with a 6-degree inner slope directs water efficiently to the center drain, preventing pooling during high-pressure operation.

Concealed Overflow: Internal overflow conduit cast directly into the structural body, pressure-tested to 0.3 MPa to prevent internal wall leaks.

Countertop Cutout: Execute strictly per the provided DXF CAD template. The cutout front edge aligns with the cabinet frame, leaving the ceramic apron suspended over the furniture edge.

Support Framing: Vanity cabinet front rail must support a vertical load capacity of at least 100 kg to accommodate downward user pressure.

Sealant Application: Apply neutral-cure anti-mold silicone continuously along the contact flange interface. Avoid acid-cure silicone to prevent porcelain enamel degradation.

Tightening Torque: Manual wrench tightening only for drain assemblies and mounting brackets. Exceeding 15 Nm torque risks stress fracturing around the waste outlet aperture.

Boutique Hotels & Resorts: Optimized for guest bathroom layouts where narrow vanity depths restrict full undermount basin integration.

Commercial Restrooms: Withstands high-frequency daily sanitization protocols using commercial-grade bleach and alkaline cleaners.

Multi-Family Housing: Standardized footprint fits modular prefabricated bathroom pods and standard production vanity lines.

Healthcare Facilities: Forward projection provides wheelchair-accessible clearance while maintaining bowl depth.

Dimensional Adjustments: Custom length modifications (500mm to 620mm) via in-house CNC mold tooling; sample lead time: 14 days.

Glaze Options: Custom color matching against RAL or Pantone ceramic color chips (MOQ: 300 units per run).

Logo Integration: High-temperature decal firing (800°C) for permanent private labeling on the rear interior wall or underside stamp.

Packaging Customization: Drop-test certified carton design incorporating client-specific UPC barcodes and brand typography.

Raw Material Testing: Incoming clay slips and feldspar powders inspected for moisture content, particle size distribution (< 325 mesh retention < 0.05%), and plasticity index.

Greenware Inspection: 100% manual check of dried semi-recessed bodies for surface pinholes, micro-cracks, and warping prior to glazing.

Thermal Shock Testing: Samples subjected to cyclic water temperatures (15°C to 90°C) to verify glaze-body expansion compatibility.

Load-Bearing Test: Static vertical load test of 150 kg applied to the front apron edge for 30 minutes to verify structural deflection resistance.

Inspection Standard: Outgoing quality control conducted per ISO 2859-1 (AQL 1.0 for major defects, AQL 2.5 for minor visual blemishes).

Individual Packaging: 5-layer export-grade corrugated master carton with 25kg/m³ high-density expanded polystyrene (EPS) corner cushioning.

Transit Validation: Packaging certified to ISTA 3A transit simulation standards, protecting against multi-axis drop shocks and ocean vibration.

Palletization: 24 units per heat-treated wooden pallet (ISPM 15 compliant), shrink-wrapped with UV-resistant film and secured with polyester strapping.

Container Capacity:
20ft GP Container: Approx. 480 units (20 pallets)
40ft HQ Container: Approx. 1,080 units (45 pallets)
