Two decades of manufacturing excellence, providing structural longevity and premium hydrotherapy experiences across global markets.
Founded in 2005, Hangzhou Kaifeng Sanitary Ware Co., Ltd. started as a small, specialized workshop with a big dream: to design and manufacture industry-leading sanitary solutions that balance luxurious relaxation with competitive engineering costs. Over the past 20 years, we have grown into a reputable brand, globally known for our dedication to high-quality, innovative, and sustainable bathroom solutions.
Headquartered in Hangzhou's prominent Xiaoshan District, our manufacturing operations are optimized for high-capacity throughput. Our massive 20,000-square-meter facility is equipped with advanced thermoforming machines, fiberglass reinforcement stations, structural chassis welding lines, and rigorous water-integrity testing zones. Today, we maintain an annual sales revenue of 10,000,000 USD, exporting over 80% of our products to highly regulated international markets including the USA, Canada, the UK, Germany, South America, and the Middle East.
Our annual output capacity stands as a testament to our industrial scale: we produce and distribute approximately 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 complete bathroom cabins. We believe that every detail matters, striving to integrate robust safety certifications (such as CUPC and CE) with modern European design aesthetics to enrich the everyday lives of end-users in over 50 countries.
Analyzing how space-saving hydrotherapy designs integrate into diverse building classifications and regional markets.
In high-density real estate markets like London, New York, and Munich, bathroom space is at a premium. Corner whirlpool bathtubs allow property developers to provide upscale, spa-like amenities within a standard 90-degree layout. By fitting into corners that are traditionally underutilized, these tubs maximize floor space, enabling designers to include double vanities or separate walk-in showers.
For B2B hotel procurement managers, a corner whirlpool tub serves as a key value-added feature to command higher average daily rates (ADR). Our double-person models (like the Anlaike KF628/KF629 series) are highly sought after for honeymoon suites and romantic retreat packages, providing guests with localized, private wellness experiences directly in their suites.
Suburban developments in the US and Canada focus on master suites with expansive master bathrooms. Incorporating a corner whirlpool tub establishes an instant marketing hook for home buyers. Our tubs come optimized with standard US/Canada plumbing dimensions and certified electrical control systems, reducing installation times for residential contractors.
Modern senior living facilities are moving away from purely clinical designs toward wellness-focused systems. The ergonomic contours, low entry thresholds, and target lumbar massage capabilities of our corner tubs support passive rehabilitation and pain management therapies for elderly residents, while complying with safety and drainage regulations.
We manufacture a versatile range of sanitary products designed to accommodate different architectural intents and spatial limits.
Equipped with targeted hydro-massage jets, ergonomic backrests, Bluetooth systems, and intelligent heating systems.
Minimalist luxury profiles incorporating high-gloss PMMA material, double-walled insulation, and pre-installed drain systems.
Engineered with SGCC-certified tempered glass, aluminum alloy framing, and heavy-duty smooth sliding mechanism.

How our manufacturing unit combines advanced chemical synthesis, fluid mechanics, and smart electronics.
Our corner tubs are molded from ultra-dense, pure PMMA (Polymethyl Methacrylate) sanitary acrylic sheets. Unlike cheaper ABS-alternative plastics, cross-linked PMMA offers exceptional resistance to scratching, UV yellowing, and household cleaning chemicals. Underneath the acrylic shell, we apply multiple layers of hand-laid high-tensile fiberglass bound with high-performance resin, reinforced along the base by high-stability plywood and a 304-grade stainless steel self-supporting frame.
True massage efficiency is dictated by hydrodynamic jet placement. Our engineers map out the jet configurations based on anatomical acupressure points. Working in tandem with UL/CE certified silent-running water pumps, the system features a balanced intake-to-outlet ratio to prevent suction blockages while delivering a constant, high-pressure mixture of water and air for deep tissue massage.
Modern luxury demands digital control. Hangzhou Kaifeng whirlpool tubs integrate IP67 waterproof digital keypads allowing users to manage water temperature, jet velocity, and LED chromotherapy lighting cycles. Our premium models feature integrated Bluetooth speaker systems, allowing users to safely stream high-fidelity audio directly through the resonant cavity of the bathtub shell.
To reduce electrical waste, Kaifeng bathtubs use double-walled acrylic construction lined with high-density polyurethane thermal foam. This structural barrier limits heat dissipation, allowing users to enjoy long hydrotherapy sessions without needing constant additions of hot water, saving up to 35% in energy consumption over standard single-shell designs.
Our production units operate strictly under the ISO 9001:2000 Quality Management System. Every corner bathtub undergoes an intensive 24-hour water inflation and static-holding test to check for microscopic seam leakages. Electric pumps and ozone generators are individually tested on specialized load cells to verify ground-leak safety (GFCI) and voltage fluctuations before final boxing. This guarantees that our B2B clients receive defects-free containers, preventing expensive return cargo fees.
Why sourcing from Xiaoshan District, Hangzhou ensures premium quality at lower production costs.
Hangzhou's Xiaoshan district is a world-renowned production cluster for sanitary products. Proximity to local acrylic sheet casting plants, tempered glass processors, and solid brass casting foundries significantly minimizes transit times and warehousing overhead. This localization allows Kaifeng to keep procurement costs low without compromising raw material specifications.
By conducting thermoforming, structural frame welding, jet assembly, and electronics routing under one roof, we eliminate intermediate processing markups. Furthermore, our strategic location in Hangzhou allows for fast, economical freight routing to Shanghai Port and Ningbo Port, reducing delivery times to B2B distributors in Europe and the Americas.
Our engineering staff specializes in converting custom CAD designs into physical manufacturing molds. Whether you need modified jet placements, specialized drain positioning, or distinct acrylic surface colors, our vertically integrated plant can build prototype mockups in under 15 days, providing customized solutions for large-scale B2B construction bids.
