HYDROTECT technology is a unique self-cleaning protective coating for building materials such as ceramic tiles. When used on outdoor surfaces and exposed to ultraviolet light, either from the sun or an artificial source, HYDROTECT’s active surface generates a reaction that cleans the material surface by decomposing organic and by oxidizing NOx (nitric dioxide) into less harmful substance. This process means that HYDROTECT, in effect, purifies the surrounding air and self-cleans.​

It can also be used for indoor surfaces. HYDROTECT-coated materials in a public urinal, for example, reduce the spread of bacteria and eliminate the bad odours generated by bacterial activity. By reducing bacteria and bad odours, HYDROTECT exemplifies TOTO’s use of technology to create hygienic bathrooms that exist in harmony with people and the environment.
