We have partnered with a neighboring craftsman in ceramics to produce vessel sink bowls that work great with our tables, or with your own cabinetry. Limited options are available at any given point, so email us for current options or a schedule for production of a custom bowl where you pick the glaze (of course the final detail is subject to the desires of the kiln). The drain hole is sized for a standard bathroom drain, but plumbing parts are not included.
