The compact high tank toilet pairs a space-saving bowl with an elevated cistern, engineered for heritage building renovations, boutique hospitality projects, and compact urban interiors. Utilizing vertical drop gravity through exposed metal flush pipes, this configuration delivers high-velocity waste extraction without mechanical pumps.
Supplied directly from hfybath.com, units are fabricated via automated high-pressure slip casting and continuous tunnel kiln firing. Production is managed for commercial contractors, regional wholesalers, and architectural specifiers requiring strict adherence to project specifications and consistent dimensional tolerances.

Product Advantages
High-Velocity Gravity Flush: Elevated water tanks create enhanced gravitational head pressure, clearing solid waste efficiently through extended drop pipes.
Space-Saving Footprint: Compact bowl projections minimize spatial intrusion, fitting narrow enclosures where standard floor-mounted models cannot clear door swings.
Vitreous China Body Integrity: Formed via 50-bar hydraulic bench presses and 140-meter tunnel kilns at 1280 degrees C, eliminating internal warping and ensuring uniform load-bearing wall thickness.
Stain-Resistant Nano-Glaze: High-temperature fused surface glazing produces an ultra-low surface energy finish that resists mineral scaling, bacterial adhesion, and chemical staining.
Corrosion-Resistant Hardware: Flush levers, wall mounting brackets, and drop pipes utilize marine-grade 304 stainless steel or forged brass to prevent galvanic corrosion in high-humidity environments.
Installation Requirements
Wall Structural Support: Upper wall structures must sustain a filled high tank operating weight of 15kg to 20kg. Solid concrete, brick masonry, or reinforced wood-stud blocking with concealed mounting plates is required prior to wall finishing.
Rough-In Verification: S-trap centerlines must align within plus or minus 2 mm of finished drain connections before floor tile installation.
Water Supply Placement: Angle valves must align with the high-tank inlet valve location, typically positioned 150mm to 200mm to the side of the vertical drop pipe centerline.
Pipe Alignment: Vertical flush pipes require rubber slip-joint gaskets and compression nuts; overtightening or angular misalignment compromises pressure sealing under surge flow.
Applications
Boutique Hotels & Historic Inns: Specified for interior schemes requiring vintage aesthetics paired with modern water-saving performance across European and North American heritage restorations.
Compact Urban Apartments: Deployed in studio apartments and tiny home developments where floor area optimization is critical.
High-End Restaurants & Pubs: Installed in themed washrooms requiring distinctive architectural character and heavy-duty commercial durability.
Historic Building Retrofits: Utilized where wall-hung carrier tanks are structurally impossible, but elevated gravity systems fit legacy vertical drainage layouts.
OEM & ODM Customization
Dimensional & Mold Modifications: Custom bowl heights, configurations, and branding embossments executed via in-house CAD engineering and CNC steel mold workshops.
Finishing Options:
Vitreous china bodies available in gloss white, matte black, biscuit, and Pantone-matched architectural colors.
Exposed metal pipes and brackets available in Brushed Nickel, Polished Brass, Matte Black, Oil-Rubbed Bronze, and Chrome plating (salt spray tested >= 48 hours).
Private Labeling: Laser-etched ceramic logos, customized carton packaging, and project-specific installation manuals.
Prototype Turnaround: 3D rapid prototyping and sample casting completed within 15 to 20 working days.
Quality Control
Raw Material Screening: Incoming clay slip and mineral feldspar undergo laboratory laser particle size analysis and shrinkage rate testing.
Dimensional Inspection: 100 percent laser coordinate measuring of greenware and fired bowls maintains trapway clearance and mating tolerances within plus or minus 1 mm.
Hydraulic Performance Testing:
Flush dye tests and ball-transfer tests are performed on every production batch to verify waste extraction capability.
Water tank assemblies undergo 0.6 MPa hydrostatic pressure testing for 5 minutes to detect micro-seepage.
Glaze Integrity Check: Ultraviolet (UV) dye inspection is applied on finished ceramic surfaces to detect micro-cracks, pinholes, or uneven glazing prior to packaging.
Packaging & Export
Export-Grade Packaging: 5-layer corrugated master cartons reinforced with internal molded EPS foam inserts custom-molded to bowl and tank contours, drop-tested in accordance with ISTA 2A standards.
Palletization: Fumigation-free plywood pallets wrapped in stretch film, reinforced with plastic strapping and corner protectors. Double-stackable configurations are optimized for 40HQ container space utilization.
Logistics Support: FOB, CIF, or DDP shipping terms supported from Ningbo and Shanghai ports, complete with Certificates of Origin, Bills of Lading, and material test reports.
FAQ
Q: What is the standard minimum order quantity (MOQ) for custom color finishes?
A: Non-standard ceramic finishes require an MOQ of 50 sets per order, while standard gloss white units support mixed container loading.
Q: How is the high water tank secured to prevent wall pulling?
A: Systems utilize heavy-duty dual wall-mounting brackets anchored into structural studs or masonry using expansion bolts, designed to withstand shear loads exceeding 150 kg.
Q: Are replacement internal valves universally compatible?
A: Internal mechanisms utilize standard G1/2 inch water inlet threads and universal flush valve assemblies, allowing maintenance using globally available plumbing components without proprietary replacements.
Q: What certifications accompany these toilets for North American and European markets?
A: Manufacturing operations comply with ISO9001 guidelines, and specific model series carry cUPC, WaterSense, and CE documentation for local building code submission.
Q: How do you handle transit breakage during ocean freight?
A: All bulk shipments include a 0.5 percent replacement parts allowance for fragile ceramic components, and verified transit damage claims are compensated via immediate credit or next-order replenishment upon photographic proof.
