One of the important points in the production of sanitary ware products, such as toilet bowls, is the accumulation of bacteria in the product. The best way to solve this problem is to use surface coatings to prevent the growth of bacteria. There will be no more space for the growth of harmful bacteria. Also, in Bergamo products, surfaces inaccessible for cleaning, such as the inside of the sewage outlet and the inside of the tank , are also completely glazed.
