When choosing a sink size for a 36-inch cabinet, it is important to consider various factors such as your cooking or washing needs, available space, and personal preferences. The dimensions of a sink for a 36-inch cabinet can vary depending on the manufacturer and specific sink model, but double bowl sinks for 36-inch cabinets typically range from 33 to 36 inches in length and 18 to 22 inches in width. According to a discussion on Houzz, a 33-inch sink or smaller should work with a 36-inch cabinet without having to notch the cabinet. World CopperSmith recommends looking for sinks marketed as 33-inch models when shopping for a sink to put into a 36-inch cabinet. Capitol Kitchens and Baths suggests that a sink should be at least 2-3 inches smaller than the cabinet size, so a 36-inch sink base cabinet can easily fit a 33-inch sink. QualityBath.com Discover notes that a 36-inch base cabinet can handle a 33-inch sink at most. Therefore, a sink that is 33 inches wide is a safe option for a 36-inch cabinet.
