Undermount Double-Bowl Kitchen Sink – Kohler Undertone K-3356

Designed with asymmetrical offset basins, this undermount double-bowl sink Revit family models clean geometry for kitchen worktop coordination. This plumbing fixture features an asymmetrical dual-basin configuration with a larger primary bowl on the left and a secondary prep basin on the right. Both compartments exhibit radiused internal corners, gently sloped basins to facilitate positive drainage, and circular drain cutouts centered within each well. The perimeter flange is profiled for seamless undermount installation beneath solid-surface or stone countertops. Its streamlined outer geometry accommodates standard base cabinets while providing clean perimeter transitions between adjacent kitchen fixtures, cutouts, and under-sink plumbing services.

The download is a 143 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Delivered as a native Revit family component, the file inserts into project environments for architectural space planning, clash detection, and MEP coordination. Users can host or align the geometry within countertop assemblies, cut sink openings in kitchen worktops, and assign custom project materials to the basin body. The clear 3D forms facilitate smooth generation of floor plans, interior elevations, and plumbing fixture schedules without excess polycount overhead.

Ideal for residential apartments, custom houses, hospitality kitchenettes, and clubhouse pantry spaces, this double-bowl basin suits contemporary culinary layouts. The undermount profile pairs naturally with quartz worktops, deck-mounted kitchen faucets, undermount waste disposers, and modular base cabinetry. Interior designers and BIM technicians frequently specify this sink type during design development and construction documentation phases when resolving kitchen work triangles, detailing island joinery, and compiling accurate architectural sanitaryware equipment schedules.
