Technological iteration accelerates, GRC prefabricated toilets move towards a new stage of high strength, thinness, and intelligence

On 2026, the prefabricated building technology network reported that with the continuous innovation of building industrialization technology, the domestic GRC prefabricated bathroom industry has ushered in a comprehensive technological upgrade, breaking through the pain points of traditional products being heavy, single in function, and lacking in intelligence, forming a trend of high-intensity, thin, and intelligent upgrading, promoting the comprehensive iteration of products from basic functional types to high-quality intelligent living types, greatly improving product market competitiveness and scene adaptability.
In terms of material performance upgrades, the new generation of modified GRC materials has completed formula innovation. Through the optimization of composite ratios of high modulus alkali resistant glass fiber, low alkalinity fast hardening cement, and nano waterproof additives, the core performance of the product has been greatly improved. The improved GRC board has a compressive strength of over 80MPa, an increase in impact strength by 35% compared to traditional products, and a waterproof penetration level of IPX7, completely solving common problems such as leakage, cracking, and aging in traditional bathrooms. It can achieve 30 years of stable and trouble free use. At the same time, the new GRC elevated ground and integrated wall panel system achieve complete separation of building pipelines, supporting later pipeline maintenance, component replacement, and space renovation, meeting the needs of the entire life cycle of the building. The landing and application of multiple high-end green building projects fully verify the stability and reliability of the new generation GRC products.
Breakthroughs in thinning and lightweight technology have become new highlights in the industry. The thickness of traditional GRC bathroom wall panels is generally between 18-20mm, and the waterproof chassis thickness reaches 25mm, which occupies a large space and has high transportation and lifting costs. After process optimization, the thickness of mainstream GRC wall panels can be reduced to 12-14mm, the thickness of waterproof chassis can be reduced to 18mm, and the overall weight of a single set of matched toilets can be controlled within 800kg. Compared with traditional cast-in-place concrete toilets, it reduces weight by more than 40%, effectively reducing the main load pressure of high-rise buildings and perfectly adapting to space limited scenarios such as renovation of old residential areas and small apartment renovations. At the same time, the lightweight and slim product design significantly improves the efficiency of warehousing, transportation, and lifting, and increases the overall construction efficiency by more than 25%.
Intelligent integration has become a standard for product upgrades. Currently, over 47% of new GRC prefabricated bathroom products integrate intelligent mirrors, IoT water-saving sensing systems, automatic ventilation, antibacterial lighting, water and electricity consumption monitoring, and other intelligent modules. Some high-end products can be integrated with smart community management platforms to achieve automatic warning of equipment failures, remote operation and maintenance, energy consumption data analysis, and other functions. In addition, the industry has added antibacterial modification processes by adding silver ions and zinc oxide antibacterial factors, achieving a surface antibacterial rate of 99.9% for GRC boards. This can effectively inhibit the growth of bacteria and mold, making it highly suitable for public settings with strict hygiene requirements such as hospitals, schools, transportation hubs, and cultural and tourism stations. Industry experts have stated that in the future, GRC technology will focus on continuous breakthroughs in three major directions: low-carbon solid waste modification, BIM full lifecycle digital control, and flexible customized production, further achieving cost reduction, quality improvement, and green upgrading.
