The Optima Total washbasin mixer, from the company Viospiral, needs 1 hole for its installation and its installation is done in inset, under-seated or hanging washbasins, which have a hole. You should check that the water flow ends up in the center of the sink so that it is fully functional.

It is mixing, meaning it has only one mixing mechanism to achieve the desired water temperature.
