A single, removable shell that conceals the innovative ultra-slim drain with a linear design. This model allows, in the case of a configuration with more than one sink, to obtain dynamic architectural elevations, for example by varying the heights of the base units and countertop tops. The linear base, with a monolithic aspect, enhances the freestanding character of this model. The different configurations allow to contextualize this Luxolid® and Luxolid® LAPILLUSTM sculpture in various locations.
