16 gauge stainless steel is about 25% thicker than 18 gauge. The 16 gauge construction makes for a strong and sturdy undermount stainless steel sink. Sinks with smaller basins (bowls) can use a lower gauge because the bowl does not need as much support.

304 Certified Stainless Steel helps withstand scratches and makes the sink more stainless, giving it a much longer life. All MR Direct sinks are built with certified 304 Stainless Steel. This is the highest quality steel that can be used in a stainless sink.

All MR Direct sinks are backed by a standard Lifetime Warranty.
