The invention is directed to an intensive use furniture component having a sealing connection on a mounting surface for sealingly attaching to a floor or wall to prevent liquid from seeping under or behind the furniture component. The furniture component is formed by an outer shell having a side wall extending generally perpendicular to the mounting surface. A mounting flange is disposed adjacent the sidewall. A bolt hole is formed in the mounting flange. The sealing connection comprises a caulk channel formed as a channel in the mounting surface for receiving a bead of caulk to fill the seam between the mounting surface and the wall or floor to prevent fluid from seeping past the caulk channel to a space adjacent the interior mounting surface.
