At approximately 100 lbs each, our Fireclay sinks are not self-supporting. However, you can give your Fireclay sink the look of a drop-in by simply installing the sink a few inches higher in the cabinet and “butting” the counter up against it. Talk to your contractor for more details on creating this look.For installation and counter cut out measurements, please make sure you have the sink on hand prior to installation as dimensions may vary. All fireclay sinks are handmade and may vary in size.
