When you purchase the John Boos UBS4-1884-2D18, you are investing in a reliable compartment sink. It has four 10” wide x 14” front-to-back x 10” deep compartments. Each has a set of removable splash mount faucet holes with 4” centers to accommodate a variety of faucet types (faucet not included). The 1-1/2” drains and overflow stand pipes keep your plumbing working reliably.
The UBS4-1884-2D18 is made of stainless steel. This 18/300 stainless steel build ensures longevity. It also makes it simple to maintain. Just wipe it clean!
