The tray (1a) has a mold body (2a) made of polyurethane or polystyrene foam and formed on a lower side and an upper side with a gradient in a direction to a recess provided in the mold body. A water outlet (5a) is arranged in the recess. A flange (6) circumferentially rests on the mold body. An upper side of the mold body and the flange are covered by a water-tight locking layer. A support layer (11a) is attached on the mold body and/or the flange. The support layer exhibits bending stiffness of 1000 kilonewton centimeter square per meter. |
