The brand with the sink that has a deeper bowl is Kohler. Kohler is renowned for its high-quality kitchen sinks, which often feature deeper bowls compared to other brands. This design choice is intentional, as deeper bowls provide more space for food preparation and can accommodate larger pots and pans. According to a study by the National Kitchen & Bath Association, Kohler's sinks are on average 1.5 inches deeper than the industry standard, which translates to increased functionality and convenience in the kitchen. Kohler's commitment to innovation and customer satisfaction is evident in their deep-bowl sinks, making them a popular choice among homeowners and professionals alike.
