The Double Basin Anthracite Erosion Sink is proof that design can carry memory. This custom piece was modeled after the bay of a lake in Wisconsin, a place of deep meaning for the client. Every contour reflects how water shapes land, capturing not only form but also the story of place.

Crafted in high-performance GFRC concrete, this dual-basin sink offers strength, longevity, and beauty in equal measure. One of the unique aspects of erosion sinks is their ability to be personalized - a shoreline where you fished with your grandfather, a bluff where you proposed, or a campsite where your family gathered. Each piece is a custom translation of memory into material, a daily reminder that design can be both functional and deeply personal.

The Double Basin Anthracite Erosion Sink is more than a bathroom fixture. It’s a handcrafted heirloom, built with healthy, crystalline silica-free concrete and sealed with a food-safe finish, designed to last for generations while carrying the story of a lifetime.

  • Handcrafted erosion sink in GFRC concrete, inspired by the contours of a Wisconsin lake.
  • Custom luxury bathroom sink design with two basins, made from silica-free concrete.
  • Modern luxury concrete sink with food-safe sealer, designed as a custom erosion piece.
