Explore our top-performing OEM clawfoot and freestanding bathtub collections built for absolute durability and architectural compliance.
In the global luxury hospitality and high-end residential real estate sectors, the bathtub is no longer merely a functional plumbing fixture. It has transitioned into an architectural centerpiece. The historical clawfoot aesthetic, dating back to the late 19th century, is witnessing a massive resurgence. However, modern commercial demands require this vintage design to be combined with cutting-edge materials. For global wholesale buyers, real estate developers, and large-scale distributors, sourcing from a competent OEM clawfoot bathtub factory is a strategic decision that affects supply chain security, margins, and brand reputation.
Historically, classic clawfoot tubs were made of heavy cast iron with porcelain enamel linings. While offering prestige, their weight (often exceeding 150-200 kg empty) poses structural challenges for multi-story hospitality projects. Modern B2B sourcing solutions prioritize high-grade, cross-linked sanitary acrylic sheets reinforced with high-density fiberglass and supportive steel frames. This engineering shift cuts weight by up to 70%, drastically reducing container shipping costs and simplifying localized installation processes, all while preserving the iconic clawfoot design.
Established in 2005, Hangzhou Kaifeng Sanitary Ware Co., Ltd. has developed over two decades from a regional workshop into a global powerhouse in high-quality bathroom equipment manufacturing. Nestled in the dynamic industrial hub of Xiaoshan District, Hangzhou, our state-of-the-art 20,000-square-meter factory serves as the central production unit for high-caliber OEM clawfoot tubs, freestanding bathtubs, intelligent massage whirlpools, frameless sliding glass shower enclosures, and modern shower cabins.

Our manufacturing capabilities are structured to handle large-scale, high-intensity B2B order pipelines. With an annual export percentage exceeding 80%, our products are distributed across the USA, Canada, UK, Germany, South America, and the Middle East. We run our production facilities under strict adherence to the ISO 9001:2000 Quality Management System, verifying every link of the supply chain—from raw monomer supply and thermal vacuum-forming processes to final edge polishing, structural frame assembly, and plumbing pressure tests.
Our yearly production output is a testament to our industrial strength: we successfully deliver 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 complete modular bathrooms annually. Through participation in major international exhibitions such as the Canton Fair, IBS (USA), and The Big 5 (Middle East), we stay at the forefront of global design trends, regulatory updates, and localized installation requirements.
Hangzhou Kaifeng Sanitary Ware designs its products with high mechanical stability and long-lasting surfaces. For our OEM clawfoot bathtubs, we use high-grade 100% pure PMMA (Polymethyl Methacrylate) cast acrylic sheets. Acrylic is lightweight, non-porous, highly resistant to staining, and easy to clean. Below is the structural layout we use to build each tub:
Our raw material starts with high-gloss sanitary acrylic sheets. This prevents discoloration, preserves deep heat-retaining capability, and offers a scratch-resistant surface.
We spray-apply 3 to 4 layers of alkali-free fiberglass and premium unsaturated polyester resin to provide impact resistance and high load capacity.
Every clawfoot tub includes a #304 stainless steel support frame underneath, directing the load to the heavy-duty brass or zinc alloy legs.
Our claw feet are engineered to withstand rigorous daily use in commercial properties. Instead of cheap plastic feet, we cast ours from premium zinc alloy or solid brass. They are then finished in Chrome, Brushed Nickel, Matte Black, or Polished Gold to match modern interior specifications.
Below is a visual layout of our production facilities in Hangzhou. This includes our vacuum-forming machinery, automated resin spraying areas, and dedicated quality inspection stations.
Exporting sanitary ware to global markets requires strict compliance with regional standards. For our primary trade routes into the US, Canada, UK, and Germany, our factory maintains rigorous quality systems. In North America, clawfoot bathtubs must comply with cUPC (Uniform Plumbing Code) and ASME A112.19.7/CSA B45.10. These certifications ensure the drains, overflows, materials, and structural integrity comply with local codes.
For European markets, our bathtubs carry the CE Mark and comply with EN 14516. This certifies that our bathtubs are cleanable, water-draining, and durable over long-term temperature cycling. We supply regional distributors with fully compliant hardware, including US-standard 1-1/2" overflow pop-up waste kits and EU-compliant low-profile traps.
To optimize logistics, our product packaging is drop-tested. We use 7-ply honeycombed cartons wrapped around reinforced OSB timber frames to handle sea container handling. This prevents cracks and surface scuffs, keeping return rates under 0.15% across global ports.
As an experienced OEM manufacturing partner, Hangzhou Kaifeng Sanitary Ware supplies bathtubs for a wide range of global building and design applications:
Hangzhou Kaifeng Sanitary Ware Co., Ltd. is continually updating its manufacturing processes. Our engineering roadmap addresses emerging ecological regulations and smart building trends:
First, we are adopting bio-derived, post-consumer recycled PMMA. This helps developers achieve LEED certification in major construction projects. Second, we are refining our manufacturing lines to reduce carbon emissions, aiming for a 35% reduction in production energy consumption by 2027.
We are also integrating smart technologies, such as thin-film heating elements embedded between the acrylic shells. These low-voltage heating elements maintain constant water temperatures without needing continuous hot-water refilling. This helps save water and energy in modern green homes.
