There are no universal building codes or regulations specifying the minimum distance between a sink and a countertop. However, practical usability and standard practices suggest a minimum distance of at least 15 to 18 inches (38 to 46 cm) between the sink and the edge of the countertop. This allows for comfortable space to use the sink, including washing hands, dishes, and other tasks without feeling cramped. Additionally, it is important to consider local building codes, manufacturer guidelines, and any specific requirements based on the type of sink or countertop being used.
