Why global procurement leaders choose Hangzhou Kaifeng Sanitary Ware Co., Ltd. as their long-term supply partner.
We source ultra-pure PMMA/ABS composite acrylic sheets, high-tensile fiberglass roving, and premium eco-friendly resins to build durable bathtub shells. The structural framing uses marine-grade #304 stainless steel or robust T6 aluminum alloy to prevent rust and bowing.
Using automated CNC vacuum thermoforming machines, we achieve consistent shell thicknesses and seamless contours. Multiple layers of fiberglass and resin are sprayed and hand-rolled onto the back of each shell, creating a highly rigid, load-bearing sanitary structure.
Adhering to ISO 9001:2000 guidelines, each whirlpool bathtub undergoes strict 24-hour hydrostatic and electrical leak testing before packaging. We inspect plumbing lines, air control manifolds, and drainage configurations to guarantee flawless performance upon delivery.

Meeting diverse technical requirements and safety certifications across major export markets.
For clients in the USA and Canada, we offer certified ASME A112.19.7/CSA B45.10 whirlpool systems. The electrical components, water pumps, and inline heaters carry cURus safety markings. Drain configurations utilize US-standard 1.5-inch schedules with integrated overflow paths, matching regional building codes.
Our custom Jacuzzi-style tubs satisfy EU health, safety, and environmental standards (EN 12764). The tempered glass shower compartments meet BS EN 14428 specifications to guarantee impact resistance. In addition, we configure electrical elements for local grids, including 220–240V/50Hz wiring with IPX5 water resistance.





Professional support tailored to real estate developers, commercial distributors, and hotel designers.
We supply hotels with high-density, double-layered acrylic tubs featuring sound-dampening bases to minimize guest noise. The smooth surface resists yellowing, scratches, and harsh sanitizing chemicals, lowering long-term maintenance costs.
We offer customized packaging designs, catalog prints, and optimization advice. Our flat-packed shower doors and stackable freestanding tubs help reduce container volume, cutting overseas logistics and warehouse expenses.
Our OEM services provide custom colors (such as matte black, glossy white, or custom outer paneling), chrome/brass hardware options, and unique layout designs (corner, round, drop-in, or free-standing) to match specific architectural concepts.
Enhancing physical therapy and recovery using intelligent controls and modern hydrotherapy designs.
Modern consumers expect integrated control systems in their home spa experiences. Our smart massage tubs offer custom controls, wireless Bluetooth audio, LED chromotherapy lights, and adjustable water-air jet pressure settings.
The integrated thermostatic heater keeps water warm during long hydrotherapy sessions, bypassing the heat loss common in standard bathtubs. Additionally, built-in ozone purification systems clean the internal plumbing lines, maintaining sanitary conditions with minimal chemical additives.
