Select high-capacity systems engineered for luxury hotels, wellness developments, and wholesale distribution.
In the contemporary B2B sanitary ware ecosystem, procurement agents, MEP engineers, and hospitality developers seek products that combine reliable engineering with modern design. Hangzhou Kaifeng Sanitary Ware Co., Ltd., based in Xiaoshan District, Hangzhou, has spent over 20 years refining the manufacture of high-performance hydrotherapy solutions.
Operating a 20,000-square-meter modern facility, we provide specialized design and production for custom two-person Jacuzzis, freestanding bathtubs, steam cabinets, and shower panel assemblies. We export more than 80% of our capacity to major markets in North America, Europe, South America, and the Middle East. Through precise production schedules and strict quality control, we ensure our global partners remain competitive.
Our commitment to material science, hydraulic architecture, and electrical compliance makes us a leading choice for high-volume commercial contracts and custom residential applications.
Our production lines are engineered to meet tight lead times for high-volume B2B orders.
A key challenge in sourcing bathtubs globally is balancing volume with consistency. Hangzhou Kaifeng addresses this through automated manufacturing workflows and skilled technicians. Annually, our facility ships 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 custom modular bathroom pods.
Our monthly production capacities include:
Our location in Xiaoshan District, Hangzhou, places us within the East China industrial zone, providing direct access to raw material suppliers (polymers, brass, structural steel) and logistics channels through Ningbo and Shanghai ports.
Ensuring products meet regional plumbing, electrical, and structural codes worldwide.
Global distribution requires strict adherence to localized safety certifications. At Hangzhou Kaifeng, we work with third-party testing labs to certify our products under standard international metrics. Our factories operate under the ISO 9001:2000 Quality Management System, monitoring every stage from sheet extrusion to final component assembly.
We custom-engineer components to meet local requirements:
| Specification Parameter | Standard Commercial Configuration | Optional Customization Upgrades |
|---|---|---|
| Shell Base Material | 3.2mm - 4.5mm Sanitary Grade Acrylic (PMMA) | Lucite® Microban Anti-Microbial Acrylic |
| Reinforcement Profile | 3 Layers fiberglass + Unsaturated polyester resin | Heavy-duty structural insulation foam backing |
| Hydromassage Pumps | 1.0 HP / 1.5 HP LX Pumps (IPX5 Rated, CE/UL) | Dual Pump Systems (Hydro + Air blower) |
| Thermostatic Heating | 1.5 kW Inline Heater with safety cut-off | 3.0 kW Rapid Heater for cold-climate usage |
| Disinfection System | Pneumatic drain cycle with residual protection | Integrated O3 Ozone Generator & UV Sanitizers |
| Control Interface | Waterproof touch panel controls (IP67) | RS485 Smart Home integration protocol |
Designed for commercial projects and luxury installations.
For boutique hotels and resorts, our double-occupancy whirlpool tubs help increase average daily rates. Built-in inline heaters and automatic sanitization cycles simplify cleaning protocols for maintenance staff.
Condominiums and premium apartments use integrated massage bathtubs to attract buyers. We design space-saving corner styles with acoustic damping pads to minimize pump noise in multi-level structures.
We provide full OEM manufacturing for sanitary ware brands. This includes custom control panel designs, unique acrylic colors, custom jet configurations, and direct drop-shipping in labeled packaging.
International shipping for oversized sanitary ware requires specialized packaging. We secure all bathtubs in multi-layered honeycomb cardboard containers with internal foam bracing, reinforced by external wood crates to prevent damage during sea transit.
We provide full tracking and export documentation for shipping. Whether delivery is direct to port or to regional distribution warehouses, our team works to minimize logistical friction.
Answers to common structural, electrical, and commercial inquiries from procurement professionals.
We use high-grade flexible PVC tubing designed to resist microbial growth and heat deformation. Joints are sealed with industrial solvent adhesives and reinforced with mechanical lock clamps. After assembly, every tub undergoes a 2-hour water pressure test to verify the integrity of the hydraulic lines.
For standard models, our MOQ starts at 5 units. For custom mold fabrications, custom structural layouts, or specific jet positioning, the MOQ typically starts at 10 units. We also support container-mix options for wholesale distributors.
Yes. We source UL-listed LX pumps and configure control systems with GFCI (Ground Fault Circuit Interrupter) protection. All plumbing and electrical systems are engineered to separate wet and dry pathways to meet US building codes.
We use non-porous PMMA acrylic sheet stocks. This material is naturally UV-stable and resistant to color fading. The cross-linked polymer structure prevents absorption of residual spa oils and chlorine, simplifying daily commercial maintenance.
We offer integrated ozone (O3) sanitizers and inline UV chambers. These systems disinfect the internal pipe network automatically during the drain cycle, helping to eliminate residual bacteria and organic compounds.
Our typical production lead time for a 40HQ container is 30 to 45 days. This includes raw material prep, thermoforming, curing, plumbing installation, and water testing. For repeat OEM contracts, we can establish dedicated material pipelines to shorten fulfillment windows.
The global demand for wellness facilities is driving the growth of high-performance hydrotherapy. Modern installations are shifting away from loud, high-power systems toward energy-efficient, targeted therapy tubs. Our design processes reflect these market dynamics.
By optimizing jet placement to target key muscle groups (lumbar, cervical, and plantar regions), we deliver therapeutic value without unnecessary energy consumption. Additionally, our dual-walled acrylic structures act as natural thermal barriers, keeping water at temperature longer and reducing heater power cycles.
For B2B distributors, offering products with verified energy ratings and low noise footprints helps capture market share in high-end developments.
