We claim the ornamental design for a sink having hidden drain, as shown and described.
|
FIG. 1 is a perspective view of a sink with hidden drain showing a first embodiment of my new design;
FIG. 2 is a perspective view showing a second embodiment thereof;
FIG. 3 is a top plan view representational of both embodiments;
FIG. 4 is a cross sectional view taken along lines 4--4 shown in FIG. 1; and,
FIG. 5 is a cross sectional view taken along lines 5--5 shown in FIG. 2.
The broken line showing of the environment is for illustrative purposes only and forms no part of the claimed design. The broken lines which define the boundaries of the claimed design form no part thereof.
