At this point it should be clear the beauty of concrete for interior furnishing purposes is that it can be poured to shape just about any form and stained to match the existing decor. That's essentially the pitch for a kitchen or bathroom sink: unique and versatile while also durable and easy to maintain. Designers use concrete to make all manner of sinks, from free-standing pedestal models to bowls intended to rest atop a counter. Like concrete tubs, these models can be shaped to fit existing space restrictions and plumbing arrangements [source: The Concrete Network].
That's not to mention concrete's fire fighting ability. Forget to blow out a candle or turn off the curling iron? At least the sink will still be standing.
