We apologize for the disappointment and difficulty you had making our Apron-Front Sink Base work with the farmhouse sink you selected. While this sink base should be a great match for most farmhouse sinks, with no additional bracing needed, we know that there is a large variety of sink types and sizes on the market. With that in mind, our cabinet offers a cut-out dimension because some sinks may require more space, while others can fit right in with no modification needed. For this cabinet, the cut-out dimensions extend to a width of 29-33" and a height of 7.5-11" and the specifications for a sink basin should also note the corresponding cut-out needed to ensure a great fit. If you have any questions or warranty needs, our Hampton Bay Customer Care Team is here to help at (888) 578-4009 or homeproducts_cc@woodmark.com. We wish you nothing but the best as you move forward with your project, and we appreciate you making Hampton Bay a part of it.
