Installation Guide
Verify countertop cutout dimensions match the inner bowl and cutout template requirements prior to permanent undermount installation.
Apply a continuous bead of high-grade silicone sealant evenly around the upper rim of the sink flange before pressing it against the underside of the countertop.
Secure the undermount mounting clips evenly around the perimeter, tightening them gradually in a crisscross pattern for balanced pressure.
Connect your 3.5-inch drain assembly and plumbing trap carefully, ensuring rubber washers are properly seated to prevent leaks.
Care & Maintenance
Daily Cleaning Rinse the sink thoroughly after each use and wipe it dry with a soft cloth to prevent water spots and mineral buildup.
Routine Washing Use a mild dish soap and a non-abrasive sponge or microfiber cloth to clean the commercial satin finish.
Grain Direction Always scrub and wipe in the direction of the stainless steel grain lines to maintain the uniform brushed appearance.
Avoid Harsh Chemicals Never use steel wool, wire brushes, or abrasive scouring powders, as these can scratch the protective stainless steel surface.
Prevent Rust Transfer Do not leave wet cast iron pans or rusty utensils sitting directly on the stainless steel bottom for extended periods.
