2. The system as recited in claim 1 wherein said channel seal forms a moisture resistant barrier along said channel interface.
3. The system as recited in claim 2 wherein said channel seal prevents water, bacteria, or debris from entering between said rimless upper edge of said stainless steel sink and said receiving channel of said solid countertop.
4. The system as recited in claim 2 wherein said channel seal comprises an epoxy resin.
5. The system as recited in claim 4 wherein said channel seal further comprises a top coat, said top coat selected to correspond to a color of said finished periphery surface of said inner periphery in order to camouflage its presence.
6. The system as recited in claim 1 wherein said countertop flange is secured to said bottom surface of said solid countertop via a countertop interconnect.
7. The system as recited in claim 6 wherein said countertop interconnect comprises at an epoxy glue.
8. The system as recited in claim 1 wherein said solid countertop is comprises granite.
9. The system as recited in claim 1 wherein said solid countertop comprises marble.
10. The system as recited in claim 1 wherein said receiving channel comprises a channel height, and said predetermined mounting depth has a tolerance of plus or minus one millimeter relative to said channel height.
11. The system as recited in claim 1 wherein said mounting assembly comprising a plurality of mounting brackets interconnected to a portion of said stainless steel sink, wherein each of said plurality of mounting brackets includes a countertop flange having a countertop flange surface, each said countertop flange surface positioned at said predetermined mounting depth below said rimless upper edge of said stainless steel sink.
12. The system as recited in claim 11 wherein each said countertop flange surface is substantially perpendicular to said sidewall of said stainless steel sink.
13. The system as recited in claim 1 wherein said channel interface measures less than one millimeter between said rimless upper edge of said stainless steel sink and said finished periphery surface of said inner periphery.
14. A method for seamless undermount installation of a stainless steel sink to a solid countertop, the method comprising:
fabricating the stainless steel sink with a rimless upper edge defining an outer periphery therearound,
preparing a mounting template based on the outer periphery of the rimless upper edge of the stainless steel sink,
creating a sink mounting aperture through the solid countertop between a top surface and a bottom surface based on the mounting template, wherein the sink mounting aperture comprises an inner periphery dimensioned to receive the outer periphery of the rimless upper edge of the stainless steel sink therein such that the rimless upper edge of the stainless steel sink is disposed adjacent and substantially coplanar with the top surface of the solid countertop when the stainless steel sink is mounted through the bottom surface of the solid countertop,
positioning at least one mounting bracket at a predetermined mounting depth below the rimless upper edge of the stainless steel sink, wherein the mounting bracket has a sink flange and a countertop flange, the countertop flange comprising a countertop flange surface which is positioned at the predetermined mounting depth below the rimless upper edge of the stainless steel sink and an adjustable countertop flange which is positionable relative to the countertop flange surface,
attaching the at least one mounting bracket to the stainless steel sink,
inserting the rimless upper edge of the stainless steel sink through the bottom surface of the solid countertop and into the sink mounting aperture such that the countertop flange surface is adjacent to the bottom surface of the solid countertop,
adjusting the position of rimless upper edge of the stainless steel sink such that the rimless upper edge of the stainless steel sink is adjacent and substantially coplanar with the top surface of the solid countertop via the adjustable countertop flange,
securing the stainless steel sink to the bottom surface of the solid countertop via the at least one mounting bracket, and
applying a channel seal along a channel interface between the rimless upper edge of the stainless steel sink and the inner periphery of the sink mounting aperture through the solid countertop, wherein the channel seal prevents water, moisture, bacteria, and debris from entering between the rimless upper edge of the stainless steel sink and the solid countertop.
15. The method as recited in claim 14 wherein the mounting assembly comprises a plurality of mounting brackets each having a sink flange and a countertop flange comprising a countertop flange surface, and wherein each countertop flange surface is positioned at the predetermined mounting depth below the rimless upper edge of the stainless steel sink.
16. The method as recited in claim 14 wherein the stainless steel sink is secured to the bottom surface of the solid countertop via a countertop interconnect comprising an epoxy glue.
17. The method as recited in claim 14 wherein the channel seal comprises an epoxy resin.
18. The method as recited in claim 14 wherein the predetermined mounting depth has a tolerance of plus or minus one millimeter.
19. The method as recited in claim 14 wherein the channel interface between the rimless upper edge of the stainless steel sink and the inner periphery of the solid countertop measures less than one millimeter.
20. A method for seamless undermount installation of a stainless steel sink to a solid countertop, the method comprising:
