John Boos UBS3-2136 3-Compartment Underbar Sink - JBUBS32136
When you purchase the John Boos UBS3-2136, you are investing in a reliable 3-compartment sink. It has three 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 UBS3-2136 is made of stainless steel. This 18/300 stainless steel build ensures longevity. It also makes it simple to maintain. Just wipe it clean! The 3” backsplash also improves the sanitation of surrounding areas by keeping spills and splashes confined to the sink and not on the walls. This prevents stains and potential water damage.
The underbar sink unit is NSF certified for commercial applications.
