The present invention involves a method for laying a wet room floor, where a water impermaeble membrane (2) is applied to a supporting floor (1), and where a market plate (7) is applied/fastened to the supporting floor; thereafter the membrane and plate (7) is concreted (4) and/or (5) and is covered, if desired, with tiles or the like. While boring through the concrete layers, the market plate will indicate whether there is any risk of puncturing the membrane (2).
