The E-250 is a double equal bowl stainless steel sink that has a patented resin rim allowing it to be seamlessly undermounted in laminate and solid surface countertops. Produced from Type 304 stainless steel, this 18 gauge sink is perfect for kitchens, labs and medical facilities where germs and bacteria need to be avoided. No seam between countertop and sink means no place for dirt to build and bacteria to grow.
