Explore our elite range of advanced hydrotherapy massage systems, premium freestanding bathtubs, and modern architectural shower enclosures.
Established in 2005, Hangzhou Kaifeng Sanitary Ware Co., Ltd. has developed into a premier manufacturer of luxury hydrotherapy and bathroom solutions. Operating from our state-of-the-art 20,000-square-meter facility in Xiaoshan District, Hangzhou, we manufacture high-performance sanitary ware engineered for residential, commercial, and hospitality markets globally. Over two decades, our capabilities have scaled significantly, and we now supply partners across 50 countries, supported by an annual sales revenue of 10,000,000 USD.
Our manufacturing efficiency allows us to distribute 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 complete bathroom assemblies every year. By implementing rigorous quality control protocols modeled on ISO 9001:2000 standards, we ensure that every smart hydrotherapy system, glass shower enclosure, and acrylic bathtub leaving our line complies with strict international performance requirements.

The production of modern Jacuzzi and massage tubs requires specialized material sciences and precision plumbing engineering. At Hangzhou Kaifeng Sanitary Ware, we use sanitary-grade cast acrylic reinforced with high-density fiberglass and structural steel support frames. Unlike lower-tier products, our acrylic shells are cross-linked to resist ultraviolet degradation, surface scratching, and chemical erosion from bathing products.
High-density polyurethane insulation minimizes heat dissipation, maintaining water temperatures longer while reducing energy consumption for the heating elements.
Engineered plumbing lines minimize hydraulic drag, delivering high-velocity water-and-air mixtures through adjustable hydro-massage nozzles.
Waterproof touch panels manage variable massage modes, integrated LED chromotherapy, FM/Bluetooth audio, and automated self-cleaning cycles.
Our manufacturing begins with raw PMMA acrylic sheets. Heated and formed using custom-tooled vacuum-forming molds, the shells are reinforced with multi-layered fiberglass resins. Heavy-gauge stainless steel frames are integrated underneath to support water loads exceeding 500 kilograms. This structural reinforcement prevents flexing and cracking over decades of usage.
To maintain high sanitary standards, our smart massage tubs feature anti-bacterial plumbing lines configured to drain water completely. Standard pipes can trap residual water, leading to microbial growth. Our systems prevent this through self-draining check valves and ozone disinfection systems that neutralize bacteria inside the plumbing lines after use.
As a global supplier, Hangzhou Kaifeng partners with hotel developers, B2B importers, construction contractors, and residential developers. We tailor our bath products to meet specific project guidelines, building codes, and logistics workflows.
For luxury hotels and resorts, durability and low maintenance are critical. Our commercial whirlpool tubs feature heavy-duty pumps, reinforced acrylic bodies, and self-cleaning sanitizers to reduce maintenance cycles. We offer multiple structural configurations, including rectangular, corner, round, and freestanding designs to match different spatial layouts.
For large residential projects, consistency, cost efficiency, and certified safety are essential. Our shower cabins, tempered-glass sliding doors, and acrylic soaking tubs provide developers with reliable options. Our flat-packed design for shower units ensures easy transport and rapid on-site assembly, helping project teams reduce installation times.
Our factory in Xiaoshan District, Hangzhou, runs structured manufacturing processes. Every product goes through multiple quality checkpoints—from acrylic thermoforming and resin spraying to frame reinforcement, water testing, and final packaging.
Every whirlpool tub undergoes 24-hour water leakage and electrical safety testing. We inspect the integrity of the plumbing joints, test the dynamic water pressure of the jets, and verify electrical insulation for pumps and control boards to ensure safe operational standards.
We export 80% of our products to highly regulated international markets. Compliance with mechanical and electrical safety codes is essential. Hangzhou Kaifeng Sanitary Ware holds certifications for various regional markets:
Sustainable manufacturing is key to our development strategy. We continue to invest in reducing our environmental footprint by using recycled PMMA materials and energy-efficient vacuum thermoforming machinery.
Our upcoming smart hydrotherapy line will feature dynamic water conservation technologies. These systems optimize jet pressure while reducing overall water volume per use. Additionally, we are developing IoT-enabled controllers that connect bath controls directly to home and hotel management automation platforms.
Technical and logistics answers for distributors, engineers, and project procurement teams.
We use high-grade PMMA sanitary-grade acrylic sheets. The shells are reinforced with multi-layered fiberglass resins and supported by stainless steel base frames to prevent cracking and structural deformation.
Yes, our products carry certifications for specific export markets, including cUPC for North America, CE for European markets, and ISO 9001:2000 quality management system certification. Electrical components are ETL and CE approved.
We provide full OEM and ODM services. B2B buyers can configure jet placement, pump power, panel integration (such as Bluetooth sound systems), dimensions, and trim finishes to match custom project requirements.
Standard container production is typically completed within 30 to 45 days after deposit verification. Shipping times vary depending on the destination port, with direct freight configurations arranged to global hubs.
Our systems use self-draining plumbing lines alongside automated ozone sterilization modules. This setup prevents water retention within the internal plumbing lines, maintaining sanitary conditions between bath uses.
Professional-grade sanitary ware designed for international distributors and commercial applications.
