The Eden Bath Semi Recessed Stone Vessel Sink with Apron in Lava Stone features a unique semi recessed design which means half of the sink is designed to sit below the countertop, and the upper half of it above. Its part drop in, and part vessel. This gives the effect of a shorter vessel sink with the functionality of a larger under mounted sink. The sink is made of honed lava stone. We recommend that you also purchase a drain with your stone sink in the same finish of your faucet.
