A baseboard having a profiled element with a substantially longitudinal extension.
The baseboard further includes one or more facilitated breakage regions which define respective detachable portions which are configured to be detached from the profiled element. The facilitated breakage regions are mutually parallel and extend over the entire longitudinal extension of the profiled element. The facilitated breakage regions are equidistant and may have non-through longitudinal incisions defined on a face of the profiled element, configured to remain in view.
