Most of such nano-finished sanitary ware is surface-structured and exhibits the dirt-repellent lotus effect that is typical of leaves. This effect helps keep surfaces clean or serves to make them easily cleanable. However, this is not achieved by using nanoparticles or by applying them to the respective surfaces but by treating the latter with chemicals.

Occasionally, some manufacturers may aftertreat the surfaces with nanoparticles. Details should be requested from them directly or from the selling shop. The probability of getting exposed to nanoparticles released from surface-structured products is very low.
