A trench eyebrow basin is a specialized type of basin that is mounted below the level of the surrounding countertop. This design creates a sleek and modern look, with a narrow trench or slit serving as the drain for the basin. The water runs into the trench and is then directed towards the drain, resulting in a unique and visually striking appearance. Trench eyebrow basins are popular in contemporary bathroom designs for their aesthetic appeal and functional design.
