Thick heavy-duty soundguard coating and thick rubber padding on the outside of the sink bowl on all sides provide sound insulation against noise and thermal insulation against condensation. The inside of the sink and the rim is finished in commercial grade brushed finish which adds to the beauty of the sink.
