Seamless undermount sink system and installation method

A mounting gasket assembly for mounting an upper edge of a sink through a bottom surface of a countertop in an installed orientation, the sink having a mounting bracket with a mounting flange including a plurality of mounting flange apertures therethrough, said mounting gasket assembly comprising:

• a mounting gasket having an upper surface, a lower surface, and a gasket aperture dimensioned to receive the upper edge of the sink therethrough,
• said upper surface having at least one sealant channel to facilitate securing said mounting gasket to the bottom surface of the countertop via a sealant,
• a plurality of mount member interconnects affixed to said mounting gasket,
• a plurality of mount members each connected to said mounting gasket via a different one of said plurality of mount member interconnects,
• said plurality of mount members dimensioned to be received through the plurality of mounting flange apertures of the sink, and
• a plurality of fasteners each engaging a different one of said mount members thereby securing the sink in the installed orientation through the bottom surface of the countertop via the mounting flange.

A method for installation of a sink through a bottom surface of a countertop, the method comprising:

• fabricating the sink with a rimless upper edge,
• attaching a mounting bracket to the sink at a predetermined mounting depth below the rimless upper edge, the mounting bracket having a mounting flange with a plurality of mounting flange apertures formed therethrough,
• positioning a mounting gasket having a gasket aperture formed therethrough on a countertop,
• inscribing an outline of a sink mounting aperture on the countertop along the gasket aperture,
• forming a sink mounting aperture through the countertop,
• aligning the gasket aperture with the sink mounting aperture along the bottom surface of the countertop,
• securing the mounting gasket to the bottom of the countertop around the sink mounting aperture,
• connecting each of a plurality of mount members to a different one of a plurality of mount member interconnects in the mounting gasket,
• aligning each of the plurality of mounting flange apertures with a different one of the plurality of mounting members,
• positioning the rimless upper edge of the sink through the gasket aperture and the sink mounting aperture, and
• securing the sink in an installed orientation via the mounting flange and each of a plurality of fasteners engaging a different one of the plurality of mount members.
