Method for manufacturing a basic model (1) of a floor drain and a heightened model (1') derived from the mentioned basic model (1) in which case the basic model (1) of the floor drain or the body forming its main part is made of plastic by casting using a casting mould. In the heightened model (1') the heightened part is formed to be a heightening (10) of the edge (2) of the orifice of the floor drain by changing the part of the casting mould forming the orifice (2) of the casting mould into another part of the casting mould with which part a heightened orifice (10) can be created in which case the altitudes (h3) and (h4) of the input pipe fitting (3) and the output pipe fitting (5) of the floor drain can be lowered in relation to the upper edge of the orifice (10) of the floor drain. |
