Abstract
Abstract A prefabricated bathroom, called a room cell, for inserting in the shell of a building, and provided with a bath and/or hand bowl and a waste water pipe extending through the floor of the cell. The main object of the invention is to provide a prefabricated room cell, in particular a bathroom of the kind mentioned, which is light and easy to transport and which is able to withstand the pressure of superimposed room cells. The object aimed at has been achieved in that below the framework there is disposed a support frame provided with a floor plate and which during transport of the prefabricated room cell is releasably affixed to the base frame of the framework by threaded bolts, and on the building site is installed in the reversed position, i.e. with the floor plate uppermost on the framework, where it is then used as a casting mould.
