Original basins are made of a durable and antimicrobial cast marble. A Korpinen classic, the Original basin has fixed rails in front to support standing and ease approach. The angle of the front rim ensures that splashes stay inside the basin. Rails are available in different accent colours, to promote better spatial recognition. Colour options for rails: white (RAL 9016), grey (RAL 7037) and red (RAL 3003).

A toilet paper dispenser, wall brackets, and fixed water trap are included with the basin. Mounting hardware sold separately. Manual and electronic height adjustments are available for the model. The basin can also be customized to include a bidé shower head. 

Original basin and rails sustain 230 kg of weight (VTT (RTE 3664/01)). Right- and left-handed basins are available, classified by the direction of the tapered tail. The recommended mounting height is 800 mm.
