An apparatus for hot dip coating metal strip is disclosed having a dip bath vessel (), a snout () which opens into the dip bath vessel for introducing a metal strip () which is heated in a continuous furnace into the dip bath, and a deflecting roller () which is arranged in the dip bath vessel for deflecting the metal strip () which enters into the dip bath in a direction which points out of the dip bath. The snout () is provided with a shaft-shaped snout extension piece () for increasing the snout dipping depth, the internal width of the snout extension piece () tapering toward its outlet opening () at least over a part length of said snout extension piece (). As a result, an increase or maximization of the eddy flow in the molten metal at or close to the metal strip () and therefore improved homogenization of the molten metal in the region of the strip is achieved, as a result of which slag-induced surface defects on the surface of the coated metal strip () can be avoided.
