The Badeloft undermount sink UB-03-BLK is a circular-shaped undermount sink in our black stone color. Ideal for medium and modest-sized bathrooms, the circular design is more accommodating to smaller spaces. Though, it has added depth for easier washing, soaking, and scrubbing. The undermount design also lends to smaller bathrooms, as it increases overall counter space.
This undermount sink is made of Badeloft’s proprietary black stone resin. A composite of natural marble and limestone, this material is incredibly durable. It is non-porous and resistant to all types of damage and stains. It is also an excellent insulator. The sink comes in a hand-buffed finish of matte or glossy black. It includes a drain cap and an overflow channel.
