Experts refer to the sink, stove and refrigerator as the kitchen triangle, the area of greatest activity, and it requires careful planning and unobstructed access. Of the three, the sink will see the most action and should have easy access to the stove and refrigerator, as well as your countertop workstations.
Sinks need to be installed in close proximity to the plumbing, but often kitchens are designed with the sinks installed right above the plumbing or in a poor location. Instead of making this kitchen design mistake, consider hiring a plumber to relocate the drains and the plumbing to accommodate the best placement for the sink.
Regardless of kitchen size or layout (L-shaped kitchen, galley, U-shaped or island style), the sum of all the legs in a work triangle should not be less than 10 feet nor greater than 25 feet. If the sum of the legs in the work triangle is too small, people will be tripping over each other and if too large, food preparation could be a very tiring task.
