I cannot call it a set, although the sinks have different series bm, gm, wr, br, sr, in fact they are the same sink with different colors. There are balls with materials in the scene.
PS: The preview mixer was used only for rendering, it is not in the archive.

Who works in V-Ray version lower than 3.1, be careful, in the materials in the BRDF section there is Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable for you
For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of the materials is adjusted taking into account PBR
