The TL-VS1815 Stainless Steel Sink is crafted from heavy-duty 18 Gauge 304 Series stainless steel. Known for its surgical-grade quality, the 304 Series offers a nonporous, rust-free, and exceptionally durable construction. Nonporous sinks are naturally antibacterial and easy to clean, with no pores for dirt and germs to become trapped in. With a chromium to nickel ratio of 18:10, our 304 Stainless Steel is among the best options for both residential and commercial installations. The elegant satin brushed finish maintains an enduring luster while effectively concealing minor scratches that may occur during normal usage. Underneath the sink, our special Protect Coating and sound deadening pads are applied to minimize noise and prevent condensation buildup. The Signature Series Sinks are backed by a Limited Lifetime Warranty, ensuring peace of mind for the original purchaser as long as they own the home where the sink is installed.
