Countertop Calculator

Before using the kitchen and bathroom countertop calculator, locate the measurements of your existing countertop, or find the dimensions on your blueprints.

Once you have measured each piece as a rectangle, enter the measurements in the Countertop Calculator.

Once you have the total square feet of countertop needed for your kitchen, bath or special room, you can also get an approximate total cost by simply adding the cost per square foot into the countertop calculator and click on “Calculate”.
