Elkay's Aqua Divide sink offers the benefits of both a double bowl and a large single bowl in one unit. The sink features a lowered partition that enables pot and pan handles or oversized items to extend over it, thus functioning as a single bowl. The 4-in. Aqua Divide also allows the sink to be utilized as a traditional two-compartment unit with separate wash and rinse areas. The Aqua Divide sinks are available in both stainless steel and e-granite materials in a variety of configurations and styles. The sinks retail from $500 to $1,995.
