Abstract: The invention relates to a self-contained bathroom comprising a prefabricated chamber intended to be placed on the floor of a room in a dwelling, said chamber containing sanitary fittings (6, 7, 8). The bathroom also includes: a means (30) for supplying clean water to the prefabricated chamber; a means (14) for collecting the wastewater generated by the sanitary fittings (6, 7, 8); and a tank (11) for storing the wastewater, said tank being connected to a drain means (14?) placed inside the prefabricated chamber in order to drain the wastewater stored in the tank. The invention is characterised in that the drain means (14?) is connected to a extendable hose (17) positioned inside the prefabricated chamber, and, while the tank remains inside the chamber, the extendable hose can be used to convey and direct the drain flow towards a drain point outside the chamber.
