I am concerned that the Moen faucet I am interested in will not fit in my thick countertop. Is there an extension kit that I can buy?

First, it is important to know how thick of a surface that a specific model is designed to be installed through. This information will be provided on the Specification Sheet. If an extension kit is still needed for your particular application, please contact us with the model number in question and we can determine the correct extension kit, if available.
