A method that includes heating a bar having an outer diameter and a length to a first temperature for a first time; extruding the heated bar to form a hollow blank having a wall thickness; forming a semi-finished blank by closing one end; bending the semi-finished blank to have an angle between first and second parts of the semi-finished blank; placing the bent semi-finished blank in a die, which is heated to a second temperature; forming a shell by injecting a gas onto or into the bent semi-finished blank after closing the die through a gas inlet in the die at a pressure for a second time, which causes the bent semi-finished blank to fit a cavity of the bathroom hardware shell shaping die; removing the shell from the die and forming a water faucet hole therein; and plating an outer surface of the shell with a coating.
