The rectangular semi-recessed basin bridges the gap between vessel sinks and undermount models. Projecting forward from the vanity unit, this configuration allows a narrow cabinetry footprint (450 mm to 480 mm depth) while maximizing internal basin washing volume.
Hfybath manufactures vitreous china and fireclay basins for commercial washrooms, hospitality developments, and multi-family residential projects. Production focuses on tight dimensional consistency, flat mounting surfaces to eliminate countertop silicone gaps, and nanometer-scale glaze finishes resisting chemical staining and thermal shock.

Product Advantages
Precision Flatness on Mating Edges: Computer-controlled grinding machines level bottom contact surfaces prior to glazing, ensuring flush seating against quartz or marble vanity tops without rocking or excess silicone beads.
Vitreous Micro-Glaze: Fired with an anti-bacterial nano-glaze producing a surface roughness Ra under 0.05 micrometer, minimizing limescale adhesion and organic residue in high-use settings.
Thermal Shock Resistance: Kiln-annealed structural bodies withstand rapid temperature shifts from 0°C to 90°C without micro-crazing, verified via 500-cycle thermal fatigue testing.
Load-Bearing Rim Integrity: Thickened perimeter walls distribute vertical downward loads up to 150 kg on the exposed front apron, meeting commercial accessibility requirements.
Installation Requirements
Cabinetry Clearance: Requires vanity units with a minimum internal cabinet depth of 450 mm. The front apron extends past the carcase by 50 mm to 80 mm per model specifications.
Countertop Cutout: Execute cutouts strictly according to physical samples or provided CAD profiles, maintaining a 2 mm tolerance margin for silicone joint expansion.
Support Framing: For wall-hung semi-recessed configurations or heavy stone countertops, install internal cabinet bracing or steel support brackets beneath the vanity deck.
Fastening & Sealing: Secure basins using mechanical underside mounting clips and apply anti-fungal neutral-cure silicone along perimeter joints. Avoid bolt overtightening to prevent localized stress fracture.
Applications
Hospitality Guest Rooms: Boutique and chain hotels requiring restricted vanity depths alongside prominent architectural basin profiles.
Commercial Office Buildings: Multi-stall restrooms needing durable, easy-to-clean sanitary fixtures able to withstand daily commercial cleaning regimens.
Multi-Family Residential: Apartment developments utilizing modern rectangular aesthetics that reduce vanity material costs via narrower stone countertops.
Healthcare Facilities: Patient rooms and administrative washrooms requiring smooth, crevice-free overflow channels complying with strict sanitation protocols.
OEM & ODM Customization
Manufacturing operations utilize high-pressure slip-casting benches, shuttle kilns, and multi-axis CNC glazing robots to execute custom project parameters:
Dimensional Alterations: Custom length and width adjustments for project-specific vanity modules (MOQ applies).
Logo Integration: Vitrified ceramic decal logos fired into the glaze at 1180°C for permanent brand protection, or laser-etched brand markers.
Overflow Customization: Basins cast with or without overflow holes based on regional plumbing codes (e.g., public commercial restrooms requiring non-overflow setups).
Packaging Customization: Drop-test certified retail cartons, pallet labeling with barcoded SKU tracking, and custom instruction manuals.
Quality Control
Internal QC protocols enforce ISO 2859-1 sampling standards across four production stages:
Raw Material Testing: Slip viscosity, density, and moisture content checked daily. Ball clay and feldspar purity verified via spectrometer analysis.
Greenware & Bisque Inspection: Post-drying inspection for hidden micro-cracks using dye penetrant testing. Bisque surfaces checked for pinholes and warping before glazing.
Glaze & Firing Verification: Post-kiln optical scanning checks glaze thickness uniformity, orange peel defects, and color chromaticity consistency (Delta E less than 0.8 against master chips).
Finished Product Audits:
Load Test: Static vertical load applied to front rims for 60 seconds.
Water Leakage Test: 100 percent water retention test on outlet and overflow channels under pressure.
Dimension Check: Laser measurement of diagonal squareness and mounting rim flatness.
Packaging & Export
Export-Grade Packaging: Individual 5-layer corrugated master cartons reinforced with molded high-density EPS foam inserts tailored to basin profiles, preventing transit shifting.
Palletization: Fumigation-free heat-treated wooden pallets (ISPM 15 compliant) stacked to 1.8 meters max, secured with heavy-duty PET strapping and stretch-wrapped with UV-resistant film.
Drop Testing: Packaging designs validated via ISTA 3A drop testing protocols to withstand international container shipping and LCL logistics.
Container Loading Capacity (Approximate):
20ft GP Container: Approx. 450 - 550 sets
40ft HQ Container: Approx. 1,100 - 1,300 sets
FAQ
Q: What is the standard lead time for bulk OEM orders?
A: Production lead time is 30 to 40 days following deposit receipt and production drawing confirmation. Peak season orders require 45 days.
Q: Do semi-recessed basins comply with North American and European plumbing standards?
A: Yes. Vitreous china and fireclay basins meet ASME A112.19.2 / CSA B45.1 (cUPC) and EN 14688 (CE) standards. Test reports are available upon request for project submittals.
Q: Can physical samples be requested before placing bulk container orders?
A: Yes. Production samples are supplied for evaluation and laboratory testing. Sample production takes 7 to 10 days, with freight shipped via international courier (DHL/FedEx collect or prepaid).
Q: What is the policy regarding transit breakage?
A: All shipments pack according to ISTA 3A standards. In the event of transit damage exceeding the agreed 0.5 percent commercial allowance, photographic evidence must be provided within 7 days of port arrival for immediate replacement or credit note issuance.
Q: What is the minimum order quantity (MOQ) for custom logo printing?
A: The MOQ for custom ceramic decal branding is 100 pieces per SKU. For custom mold development and proprietary geometric designs, contact the engineering team for tooling cost and minimum volume assessments.
