How to measure the depth of your countertop
The width (front-to-back measurement) of the sink that can be used is determined by this measurement.
DROP-IN SINKS:
For laminate countertops with a backsplash, you can install a drop-in sink that is up to 20 1/2" deep.
For laminate or stone countertops without a backsplash, you can install a sink that is up to 22" deep
UNDERMOUNT SINKS:
Consult your installer. These measurements are important to ensure that enough space is allocated for fixtures and backsplash material behind the sink.
How to determine the minimum cabinet size
Measure the cabinet size under the existing sink or where the new sink will go.
Measure from gable to gable (left to right). See diagram.
Be sure to measure from outside edge to outside edge.
To save time, double check your measurements.
This is the "Minimum Cabinet Size", and this size is noted next to each sink model in the BLANCO catalogue. Standard kitchen cabinets come in size increments of 3" (for example: 18", 21", 24", 27", 30", 33", 36" etc.).
