Why does water pool in flat bottomed sinks?
Flat-bottomed sinks lack the slope needed to direct water toward the drain, causing moisture to pool at the edges and in the corners. This pooling leads to algae growth within weeks and forces people to constantly dry the sink manually with a squeegee or cloth, which is not sustainable.
