Major Appliances

Refrigerator

A rectangle approximately 36 inches wide and 30 inches deep, sometimes with a small arc indicating the door swing direction. Often labeled REF or with a snowflake icon.

Also: fridge, refrigerator/freezer

Found in: End of a counter run, near the kitchen entry for easy grocery access

Range / Stove

A rectangle with four circles arranged in a square pattern representing the burners. A freestanding range includes the oven below in one unit, drawn as a 30-inch wide rectangle.

Also: stove, cooktop and oven, range

Found in: Along a counter run, usually against an exterior or interior wall with a vent hood above

Wall Oven

A square or rectangle drawn within the cabinet line, often with concentric arcs or circles inside representing the oven cavity. Mounted at counter or eye level in a tall cabinet.

Also: built-in oven, single oven, double oven

Found in: Built into tall cabinetry, often paired with a separate cooktop elsewhere

Dishwasher

A 24-inch-wide rectangle adjacent to the sink, often labeled DW. May show a slightly different fill or hatch pattern to distinguish it from base cabinets.

Also: DW, dish washer

How to Read Kitchen Floor Plan Symbols

Kitchen plans are among the most detailed in a set of floor plans because they pack many appliances and fixtures into a small area. Start by identifying the sink — it is usually drawn as a rectangle with one or two oval basins inside, placed along an exterior wall (near the window, if there is one). The range or cooktop is drawn as a rectangle with four circles representing burners.

Appliances are drawn to scale, so you can judge the physical space each one occupies. A refrigerator is a rectangle (typically about 36 inches wide and 30 inches deep) often placed at the end of a counter run. The dishwasher is a narrow rectangle (24 inches wide) usually next to the sink. Look for the work triangle — the imaginary path between the sink, range, and refrigerator — which should be efficient and unobstructed.

Cabinet runs are shown as a band along the walls, often with a thinner line for upper cabinets drawn in a dashed or lighter style. The countertop depth is usually 25 inches, and base cabinets are 24 inches deep. Islands and peninsulas are drawn as freestanding or attached rectangles, sometimes with a sink or cooktop symbol embedded in them.

Pay attention to clearance spaces. There should be at least 42 inches between opposing counters (48 inches is better if two people cook). Appliance doors — ovens, dishwashers, refrigerators — need room to swing open without blocking pathways. The plan should show enough space for these operations.

Common Mistakes

A frequent mistake is assuming all rectangles along the counter are the same — you need to check labels or compare sizes to tell a dishwasher from a trash compactor or a built-in oven from a cabinet. Another error is ignoring the swing space needed for the refrigerator and oven doors. People also overlook the difference between a cooktop (flat, set into the counter) and a freestanding range (a single unit with oven below), which affects cabinetry layout significantly.

Pro Tips

• Look for the work triangle between sink, stove, and refrigerator — each leg should be 4 to 9 feet for an efficient kitchen.
• Check that the dishwasher is within arm's reach of the sink for easy loading and plumbing access.
• Verify that appliance doors won't collide when open — especially the refrigerator, oven, and dishwasher.
