Bathroom sink sizes
Bathroom sinks are available in a wide range of sizes and actual dimensions are never standard parameters but rather measurements determined by manufacturers depending on a type and style of a certain sink.
Undermount rectangular sink might vary from 16 to 24 inches in width (side to side measurements) and from 12” to 18” in depth (front to back measurements). Actual interior bowl dimensions will be 1 1/2 – 2 1/2 inches smaller around the whole sink perimeter. Typical height from the top to lowest point of undermount vanity sink usually stays within 7 – 9 inches. It doesn’t mean the actual dimensions will be limited to these numbers and some sinks might be wider of deeper. But usually undermount bathroom sink do not exceed 30” in width and 22” in depth.
Rounded vessel sinks typically vary from 14 to 20 inches (36 – 51 centimeters) in diameter and 4” – 7” in height.
Wall mounted or pedestal lavatory sinks with overall dimensions 24”W x 20”D x 6”H have smaller bowls and some additional space from sides for an accommodating hand soap dispenser or other smaller bathroom accessories.
Vanity tops with integrated sinks come as one solid unit and very often are made accordingly to some standard cabinet dimensions with 0.5 inches overhung from both sides and 3/4” – 1” from the front.
