Explore our premium range of aluminum-frame shower doors, freestanding bathtubs, and customized massage whirlpools for global architecture and hospitality requirements.
A global benchmark in design, technology, and manufacturing of high-grade shower cabins and freestanding bathtub structures.
Founded in 2005, Hangzhou Kaifeng Sanitary Ware Co., Ltd. started as a small, precision-focused workshop with a massive long-term ambition. Over the course of 20 years of expertise in the industry, we have expanded to become a highly reputable global brand. Our core philosophy is to combine modern design aesthetics with heavy-duty structural utility to support residential, commercial real estate development, and upscale hospitality projects.
By utilizing smart materials and maintaining consistent communication with international designers, our products have successfully reached homes and hotels in more than 50 countries worldwide. We believe every detail in the bathroom environment serves a structural and sensory purpose.
At Hangzhou Kaifeng, production operations are executed under the strict guidance of the ISO 9001:2000 quality management system. Quality control begins at the raw material stage: every batch of tempered glass undergoes physical compression and fragmentation tests, and aluminum profiles are verified for wall thickness and mechanical tempering profile.
Our quality control loop integrates feedback from structural mock-ups, continuous product improvements, and rigorous stress testing. From pre-assembly hardware dry runs to final packaging load-ins, we guarantee that all items leaving our facility match the top global engineering thresholds.
How cutting-edge material science, nanotech coatings, and hardware design are redefining modern bath environments.
Modern commercial and residential buyers demand low-maintenance solutions. The technology roadmap for tub doors emphasizes factory-applied cross-linked polymer coatings (EnduroShield type) that seal microscopic valleys in glass surfaces. This prevents hard water deposits, body oils, soap scum, and silica corrosion. Our future models integrate dual-side curing processes, extending the longevity of the easy-clean properties up to 10 years under continuous daily use conditions.
Traditional chrome finishes are giving way to Physical Vapor Deposition (PVD) finishes, especially in Brushed Gold, Matte Black, and Satin Nickel. PVD technology coats hardware with a molecular layer of ceramic compound, ensuring 3 times the hardness of chrome and a lifetime resistance to scratches, abrasions, and chemical cleaner damage. Roller structures now incorporate ceramic balls and self-lubricating synthetic sleeve cases to pass 120,000 sliding cycles tests.
Looking to the future, the integration of Polymer Dispersed Liquid Crystal (PDLC) switchable smart glass is moving from high-end corporate suites into residential bath designs. At the flip of a switch or via automated smart-home sensors, the clear tempered glass instantly shifts to opaque white, offering on-demand privacy. Our engineering department is designing low-voltage tracking lines integrated into structural aluminum frames to deliver power safely and discreetly.
Engineered layouts designed to maximize usability, safety, and spatial value across diverse architectural landscapes.
For compact urban apartments and hospitality developments where swing space is limited, sliding tub door configurations offer the ideal space utilization. By utilizing dual bypass systems, users can access the tub controls from either side without stepping in. Our bypass tracks incorporate bottom guiding blocks and heavy top guide bars to ensure smooth tracking without lateral movement, keeping water completely inside the splash zone.
Frameless pivot systems are preferred for clean, contemporary designs. By eliminating bulky perimeter aluminum profiles, light passes through the glass freely, visually expanding the bathroom footprint. Solid brass self-centering hinges ensure the door stays closed, while high-elasticity magnetic PVC gaskets create an airtight water seal along the door edge, preventing splashes onto wood laminates.
Folding tub doors offer an alternative for mixed-use wet zones. By utilizing multi-panel structures with high-tensile silicone hinges, the glass panels fold neatly back against the wall, allowing unrestricted access for tub cleaning, bathing children, or moving large objects. Ideal for families and boutique residential suites wanting the flexibility of a bathtub and a walk-in shower in one footprint.

How Hangzhou Kaifeng’s advanced facilities in Xiaoshan District optimize scale and deliver reliable quality.
Operating a massive 20,000-square-meter facility, Kaifeng maintains an impressive production speed to fulfill large B2B distribution orders. Our production lines output 1,500 bathtubs, 1,500 shower rooms, and 2,000 shower panels monthly. Annually, our company sells over 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 complete modular bathrooms, yielding an annual sales revenue of $10,000,000 USD.
Our exports account for over 80% of our business, targeting regions with strict quality expectations: the United States, Canada, the United Kingdom, Germany, South America, and the Middle East. This scale helps protect our supply chain against shipping delays and pricing swings.
Our factory processes combine automation with detailed craftsmanship. Glass tempering is carried out using horizontal convection furnaces, ensuring flatness and safety. Hardware profiles are shaped using computer-controlled CNC systems, and automated packaging lines wrap, seal, and palletize our products safely.
We regularly host buyers at our production site to inspect our operations. The following gallery shows our manufacturing spaces, testing areas, and warehousing setup.
How we address the quality, lead time, and compliance requirements of wholesale distributors and builders.
We work closely with B2B buyers to customize tub doors according to project specifications. This includes adjusting heights, widths, glass styles (such as frosted, rain, or ribbed glass), and frame finishes (matte black, brushed brass, or satin nickel). Our engineering team can work from architectural CAD drawings to design customized assemblies that minimize installation times on-site.
Heavy tempered glass requires robust protective packaging for long-distance transit. We use drop-tested packaging layouts that utilize high-density foam corners, heavy honeycomb outer boxes, and internal protective film. This secures the glass against vibrations during maritime transport and subsequent warehouse handling.
We schedule production carefully to deliver bulk orders on-time. Our location in Xiaoshan District, Hangzhou, offers direct logistics routes to major container ports in Ningbo and Shanghai. We manage custom clearances and prepare documentation to keep your global logistics run smoothly.
Our products are engineered and tested to comply with international sanitary ware certifications.
To support global imports and local building permits, Kaifeng sanitary ware conforms to key international standards. Our glass and hardware configurations meet SGCC (Safety Glass Certification Council) and EN 14428 requirements, which govern load bearing capacity, impact resistance, and durability. This compliance ensures that our products are ready for immediate specification in commercial and residential construction projects.
Additionally, we participate regularly in international exhibitions such as the Canton Fair, IBS (USA), and The Big 5 (Middle East) to stay updated on shifting local regulations and standards.
