The trough sink was made to mimic the antique style trough sink of the past which had a flat bottom. You may experience puddling or standing water if the sink is not 100 percent perfectly level, this is normal for a trough sink. One solution is to sponge dry the sink or wipe the sink dry at the end of the day eliminating the water standing. If the water not draining on the ends is still an issue, you could return the sink under warranty. We will stamp the sink with a contoured bottom sink; however, even with the contoured bottom it would not drain as effectively as a round sink due to the nature of the trough sink design.
