Bath facility by E.Zoll

I saw a washbasin with a cabinet from the company Zoll in Sigmaringen in a hardware store that I liked very much and is also acceptable in price including the cabinet. I assume that the company Zoll does not manufacture the ceramic washbasins themselves. Does anyone know this manufacturer or know who makes the washbasins?

Why don't you ask first at the hardware store and then with a picture and designation directly at the manufacturer :)?
