Commercial Product Overview

Best for restaurants needing reliable warewashing performance, sanitation confidence, and correct installation fit.
Designed as a practical anchor for a professional wash area, the EFI SI818-1B is a 66-inch-wide corner-drain compartment sink in 18-gauge Type 304 stainless steel. This one-compartment model combines one 18 x 18 in. bowl, 11 in. deep, with drainboards on both sides. It gives buyers a specific combination of bowl capacity and staging space instead of a one-size-fits-all compromise.
