III. Key items of concern for quality and safety of shower rooms

In recent years, there have been safety incidents caused by broken glass in shower rooms, which seriously threaten the personal safety of consumers. So how to buy shower room products to avoid such safety incidents?

Based on the monitoring and analysis of the quality and safety risk information of domestic and foreign shower products and the data analysis of the national building and sanitary ceramics testing key laboratory on the product testing of shower rooms, the main reason for the safety incidents caused by broken glass in shower rooms is the quality of the glass of the water barrier screen in terms of safety performance.


Tempered glass

After heat treatment process, the glass is characterized by the formation of a compressive stress layer on the surface. It has improved mechanical strength and heat-resistant impact strength, and has a special fragmentation state.


Laminated Glass

Glass with materials such as glass and/or plastic. It is the collective name for composite materials which are separated by an interlayer and made to adhere together by treatment. What is commonly and mostly used is the component which is separated by an intermediate layer and made to stick together by treatment.



★ China’s standard QB 2584-2007 “shower room” has made clear provisions for the use of water screen glass, as shown in Table 1 and Table 2.

Small reminder.

When purchasing shower products, whether through traditional trade or cross-border e-commerce platforms, consumers should ask for a test report issued by a third-party testing agency and check the type of water barrier glass. If it is tempered glass, you should also check whether it is labeled with the 3C certification mark. In addition, in daily use, you should avoid contact with sharp objects collision, to prevent the phenomenon of glass spontaneous explosion.
