How do you measure your space correctly?
If this is a simple replacement, measure the length, width, and height of your current sink and choose one with the same measurements. Measure length from side to side and width from front to back. Where you measure will depend on the installation type.
Be sure to refer to the specification sheet for exact dimensions. Height and depth are two separate measurements. Height is the full measure taken on the exterior from top to bottom. Depth is the interior measure of the basin and the depth of water it will hold. Sinks with an overflow are measured from the deepest point to the overflow only.
