What to consider before buying a sink:

Whether you are replacing your sink or renovating the kitchen, you must always know your cabinet and countertop dimensions. If you are only replacing the sink, it needs to fit the existing cutout space. And if you are renovating, you may be able to install a larger sink by expanding the cutout.

Correct measurements are very important to ensure that enough space is allocated for the faucet, fixtures and other materials behind the sink. Your installer will also consider the bowl depth to ensure there is adequate space underneath.

One of the most important criteria for choosing sink size is finding a sink that fits the cabinets.
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.).

Countertop depth refers to the measurement from the front to the back of the countertop
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.

    • 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
    • Consult your installer. These measurements are important to ensure that enough space is allocated for fixtures and backsplash material behind the sink.
