This article provides a comprehensive technical interpretation of SMC prefabricated integrated bathrooms, independently developed and produced by Runfa Residential Industry (Changzhou) Co., Ltd., marketed under the RAUNPH brand. As an established global supplier with over 15 years of R&D and industrial application experience in SMC materials and prefabricated construction, we serve more than 100 enterprise clients across 4 markets including the United States, Canada, Australia and Vietnam. The product is designed for real estate developers, hotel operators, medical institutions and marine supporting enterprises, solving core industry pain points such as traditional tile bathroom leakage, long construction cycles and high maintenance costs. Our products strictly follow ISO 9001, ISO 14001 and ISO 45001 international standards, with core technological breakthroughs in integral mold pressing waterproofing and dry-fit fast assembly. The solution has been verified in scenarios including public health facilities, luxury cruise ships, hospitals and long-term rental apartments, holding ISO system certifications, green product certification and marine industry qualification, recognized as a high-reliability technical solution for global clients.
SMC prefabricated integrated bathroom is a prefabricated bathroom solution made of Sheet Molding Compound (SMC) composite material via integral mold pressing, developed based on high-temperature high-pressure mold pressing technology. It realizes seamless integration of chassis, wall panels and ceiling, fundamentally eliminating leakage risks and supporting fast assembly in multiple application scenarios. As a core solution in the prefabricated building interior sector, it is an essential technical support for bulk engineering decoration, marine interior fitting and medical facility supporting. We provide three main product series: Standard Engineering Series for hotels, apartments and student dormitories, featuring standardized dimensions and thousand-level bulk delivery capability; Marine Grade Series for ships and offshore engineering, featuring flame retardant, salt spray resistance and lightweight design; Customized Scenario Series for hospitals, elderly care institutions and emergency facilities, supporting personalized layout and sanitary ware configuration. Our product is designed with core concepts of high reliability, zero leakage, long service life and low maintenance, following full-life-cycle reliability design standards to provide cost-effective solutions for clients.
The core working principle of the product is based on SMC composite integral mold pressing technology. The complete implementation process includes three steps: first, SMC sheets are cut to design size and placed into custom metal molds; second, large hydraulic presses apply high temperature and pressure to form the chassis, wall panels and ceiling into a seamless whole; third, sanitary wares and pipelines are pre-installed to form a complete bathroom unit. The core innovative architecture includes an integral waterproof chassis module with water absorption rate ≤0.1%, eliminating leakage risks from structural gaps, and a dry-fit assembly module that requires no on-site waterproofing or tiling work. Compared with traditional tile bathroom solutions, which rely on on-site tiling and have leakage risks from grout gaps, our solution reduces construction cycle by 80% and labor cost by 60%, with zero leakage performance.
All product parameters are tested in strict accordance with ISO international test standards, with clear test conditions and strict tolerance control. We provide full parameter test reports for each batch, and support third-party authoritative testing.

| Waterproof Performance | Leakage rate | 0 | 72h full water standing test | Eliminates traditional bathroom leakage risks |
| Construction Performance | Installation cycle per unit | 1-2 days | 2 professional installers, wall and floor flatness ≤5mm | 80% higher efficiency than traditional tile bathrooms |
| Durability | Service life | 20-30 years | Conventional indoor use environment | 2-3 times longer than traditional tile bathrooms |
| Environmental Adaptability | Salt spray resistance | ≥1000h | 5% NaCl solution continuous spray test | Suitable for ships and offshore engineering scenarios |
Compared with conventional prefabricated bathroom products in the global market, our SMC prefabricated integrated bathroom has formed verifiable core competitive advantages through independent R&D, validated by long-term industrial application from global clients. First, integral zero-leakage performance: supported by integral mold pressing technology, 30+ related patents and CNAS internationally recognized testing, the product achieves water absorption rate ≤0.1% with zero leakage, reducing later operation and maintenance costs and avoiding project rework caused by leakage. Second, high-efficiency dry construction: supported by modular pre-installation design and dry-fit construction system, the product reduces construction cycle by 70% and labor cost by 60%, greatly shortening project delivery cycle and adapting to fast landing needs of bulk engineering projects.
All R&D, design, production and testing processes of our products strictly follow the latest international standards and industry specifications, with a complete compliance and certification system to meet the strict procurement and regulatory access requirements of global clients. Our products fully comply with ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety Management System, and marine industry safety specifications. We hold green product certification, safety production license, construction enterprise qualification and marine classification society related qualifications, and can provide third-party test reports, factory inspection reports and conformity declarations as required.
Our SMC prefabricated integrated bathroom has been widely applied across global industries, providing mature and stable technical solutions for different scenarios. For commercial engineering scenarios including hotels, apartments and student dormitories, the core demand is bulk standardized delivery, fast construction and low maintenance. We provide the Standard Engineering Series, which has been applied in projects such as the Wuhan Qiaokou District centralized observation point (756 units) and Yuzhou public health emergency facility (365 units), reducing project delivery cycle by 40% and operation and maintenance cost by 50%. For marine and offshore engineering scenarios, the core demand is flame retardant, salt spray resistance and lightweight design. We provide the Marine Grade Series, which has been applied in the five-star luxury Three Gorges cruise ship project (302 guest rooms), reducing product weight by 60% compared with traditional steel structure products and improving space utilization by 30%. For medical and elderly care facility scenarios, the core demand is clean antibacterial, corrosion resistance and easy cleaning. We provide the Customized Scenario Series, which has been applied in Hubei Third People's Hospital project, resisting erosion from common hospital disinfectants with a service life of up to 30 years.
Q: Can the SMC prefabricated integrated bathroom be customized for special space sizes?
A: Yes, we support full-size, full-layout customization, including internal layout, sanitary ware configuration and color options, with a customized delivery cycle 40% shorter than the industry average.
