The penetration rate of prefabricated interior continues to increase, and GRC bathroom accelerates the replacement of traditional cast-in-place bathroom

In 2026, with the continuous acceleration of domestic construction industrialization, the popularity of prefabricated interior decoration is increasing year by year, and the traditional on-site wet decoration mode is accelerating its exit from the market. In the field of bathroom renovation and construction, GRC prefabricated bathrooms, with their comprehensive advantages of efficiency, quality, environmental protection, and cost, continue to accelerate the replacement of traditional cast-in-place ceramic tile bathrooms, and the industry substitution effect continues to highlight, becoming the core trend of building interior upgrading.
For a long time, traditional cast-in-place and tile laying methods have been the main methods for building and bathroom decoration in China, relying on manual on-site construction. The process is cumbersome, the construction period is long, and the construction quality highly depends on the technical level of workers. It is prone to quality problems such as substandard waterproofing, hollow tiling, wall cracking, and dimensional deviation, resulting in a high rate of leakage and rework in the later stage. At the same time, the traditional construction mode has a large amount of consumables, a lot of construction waste, and serious pollution, which does not conform to the current trend of green building, low-carbon construction, and efficient construction in the industry. The upgrading and replacement of the industry is urgent.
Compared to traditional decoration models, the substitution advantages of GRC prefabricated toilets are highlighted in all aspects. In terms of construction efficiency, traditional bathroom decoration takes at least 20 days from grassroots treatment, waterproof coating, tile laying to maintenance completion, while GRC prefabricated bathroom factories prefabricate and assemble on site, completing the entire installation in 1-2 days, improving construction efficiency by more than 90% and significantly shortening the project construction period. In terms of quality assurance, industrialized standardized production completely avoids manual errors, and the overall seamless structure solves leakage problems from the root. The product has strong stability, long service life, and almost no rework in the later stage. In terms of environmental protection and energy conservation, the entire process is dry construction, with no dust, no sewage, no construction waste, and is green and pollution-free. In terms of overall cost, although the initial procurement cost of individual items is slightly higher, there is no need for repeated maintenance in the later stage, and the overall cost of the entire life cycle is much lower than that of traditional decoration models.
With the improvement of consumer living quality, the popularization of industry awareness, and the mandatory requirements of policies for prefabricated construction, the market replacement speed of GRC prefabricated toilets continues to accelerate. Data shows that the penetration rate of prefabricated bathroom fixtures in newly built residential buildings in China has exceeded 28% by 2025, with the fastest growth rate of GRC material substitution, exceeding 12% annually. Industry institutions predict that in the next five years, the market share of traditional cast-in-place bathroom will continue to decline, and the penetration rate of prefabricated bathroom will exceed 50%. GRC material, with its comprehensive cost-effectiveness advantage, will continue to seize the traditional market and become the mainstream model of bathroom decoration.
