Great sink, perfect dimensions for a small bathroom counter at 15" wide and 10" deep on the inside. Nice finish and modern square corners too. We first ordered another brand that was 10" deep too but only 13.5" wide. And it was too small but also looked "off" in dimensions. A 3 to 2 ratio for width to depth is aesthetically perfect..
