KOHLER® and STERLING® stainless steel sinks are made from 16- to 21-gauge type 304 and 301 stainless steel.
The stainless steel is made of a chrome and nickel alloy that assures the sinks provide exceptional resistance to stains and corrosion.
The lower the gauge, the thicker the steel. Thick steel is less likely to dent and is more sound resistant.
Premium KOHLER sinks are made from 18- and 19-gauge stainless steel.
SilentShield sound-deadening pads are applied to all STERLING and all KOHLER kitchen sinks.
The pads are made of a rubber compound and significantly reduce noise from clanging dishes and from running water and disposals.
SilentShield Plus reduces condensation and helps maintain water temperature, in addition to providing the same sound-absorption quality that SilentShield sinks feature.
Most KOHLER stainless steel bathroom, kitchen, utility, and bar sinks have a standard finish (-NA).
Some sinks have two different finish options: Mirror finish (-MU) and Luster (satin) finish (-SU).
