Abstract: A plurality of prefabricated modular kitchen units are adapted for floor-to-ceiling installation along at least two intersecting kitchen walls for minimizing installation time and obviating the necessity for finishing the walls along which the units are installed.Installation is facilitated by a corner unit construction that permits the end-wise insertion of spaced connectors for joining spaced perpendicularly related modular units to adjacent sides thereof, as in an L-shaped layout at a kitchen corner, and in the formation of cooperating recesses or cavities in the various units to house the necessary wiring and plumbing. Complete coverage of a wall along which the units are installed is assured adjacent the ceiling by an adjustable lighting module which performs the dual functions of lighting the kitchen and providing an adjustable molding between the modular units and ceiling while any variations between the wall length and installed units is compensated for by the installation of a modular panel section.
