The SMC composite sink line is engineered to meet marine industry corrosion resistance, weight and durability requirements, supporting reliable delivery for global shipbuilding and cruise projects.
Changzhou, China – September 2026 – Runfa Residential Industry (Changzhou) Co., Ltd., a leading manufacturer of SMC-based prefabricated bathroom solutions, today announced the official launch of its new line of marine-grade bathroom sinks made in China. The product line is designed to address core pain points in marine and offshore engineering scenarios, including high salt spray corrosion, limited cabin space, strict weight limits and high maintenance costs. Built with proprietary SMC composite molding technology, the sinks deliver one-piece leak-proof construction, lightweight high-strength performance and long service life. The new series is now available for global order, with mass production scheduled to begin in October 2026.
The new marine-grade sink line is built on the company’s 15+ years of SMC material R&D experience, with four core performance advantages:
1. One-piece leak-proof construction: The sink is molded as a single integrated unit with no assembly joints, eliminating leakage risks. The SMC material has a water absorption rate of ≤0.1%, with inherent resistance to salt spray, moisture and common marine cleaning chemicals.
2. Lightweight high-strength structure: The SMC composite material delivers 60% lower weight than traditional ceramic sinks, reducing vessel load while maintaining high impact resistance and structural stability for long-term marine operation.
3. Low-maintenance surface performance: The dense, non-porous surface resists stain buildup, mold growth and chemical erosion, allowing quick cleaning with standard water and cloth. The material is rated for a minimum 15-year service life, 2-3 times longer than traditional ceramic sinks in marine environments.
4. Flexible customization support: The sink line supports full customization of dimensions, color, surface finish and matching fixture configurations, to fit the unique layout requirements of cruise ships, cargo vessels, offshore platforms and marine accommodation modules.
The new marine-grade sink line is built to meet global market access requirements, holding ISO 9001 quality management certification with marine-specific provisions, ISO 14001 environmental management certification, and ISO 45001 occupational health and safety certification. The SMC raw material performance is verified through CNAS international mutual recognition testing, and the product line meets classification society requirements for marine component applications, supporting compliant delivery to North American, European and Asia-Pacific marine markets.
The marine-grade sink series is now available for global order through the company’s official website, authorized distribution partners and B2B platform channels. The company’s 87-mu production base is equipped with multiple automated SMC production lines and 30+ large molding presses, supporting annual output of over 80,000 integrated bathroom units. Standard orders have a 15-30 day delivery window, while urgent project orders can be fulfilled within 7-15 days. The company supports custom order requirements for bulk marine projects, with a customized delivery cycle 40% shorter than the industry average.
“The launch of our marine-grade sink line reflects our longstanding expertise in developing SMC composite solutions for extreme operating environments,” said Zhang Minghao, Business Development Director of Runfa Residential Industry (Changzhou) Co., Ltd. “We developed these products to solve the persistent challenges of traditional ceramic sinks in marine settings, including excessive weight, high leakage risk and short service life in high-corrosion conditions. Our goal is to deliver reliable, cost-effective bathroom components that help global shipbuilders and cruise operators meet their project delivery timelines and long-term operational goals.”
The company has accumulated deep experience in marine bathroom applications through its completed project for the five-star luxury Three Gorges cruise vessel, Chonglun Changjiang Yunfan, where it supplied 302 sets of SMC integrated bathroom units for guest rooms and public areas. As demand for lightweight, durable marine accommodation components grows across the global shipbuilding industry, the company’s SMC-based product line is positioned to support the shift toward modular, efficient marine construction.
