are not suitable for showing dimensions or proportions as shown in fig1 the shower drainage outlet comprises a first part 2 a second part 6 and a third part 8 in this arrangement the first part 2 shower tub outflow can be slid from above into an opening in the shower tub 3 in this arrangement the bearing surface 10 of the first part 2 comes to rest against the top of the shower tub 3 as a result of the overlap between the bearing region 10 and the top of the shower tub 3 horizontal tolerances may be compensated for without this leading to a loss of the sealing integrity in the region of the bearing surface 10 in order to enhance the sealing integrity a sealing element 14 may be provided which is for example designed in the form of a coating film sealing mat o ring or the like the first part 2 with the bearing surface 10 may thus be slid against the shower tub 3 apart from the connection from the discharge container in this case the shower tub 3 to the pipe work the shower drainage outflow also comprises a waterproof hole through a single part or multi part floor layer 4 5 furthermore said shower drainage outflow provides the option of compensating for horizontal vertical and angular tolerances between the components to be connected thus a connection between the shower or hand basin sink unit or the like to the waste water system whose pipe work extends underneath the cabin floor may be provided the outflow comprises a three part housing 2 6 8 which is to compensate for the tolerances that occur.
