We are very sorry to learn of the issues that you have seen and the concerns you have with your Vanity cabinetry, Dan. The cabinet boxes are constructed using Furniture Board with pocket screwed joints and encapsulated panels for durability and added strength, backed by a Limited Lifetime Warranty. Certainly, what you have experienced is not to be expected, and your feedback is essential in our efforts to improve that experience.
We are here to help in any way that we can and would like the opportunity to discuss your project with you. Please reach out to your Hampton Bay Customer Care Team by phone at (888) 578-4009 or by email at homeproducts_cc@woodmark.com. Email may be best if you would like to share photos and, if possible, be sure to include any model numbers (i.e. KVDB12-SW) that you have so that our team can best assist you. We hope to help guide you toward the next steps in completing your project just as you envisioned, and we thank you for making Hampton Bay a part of it.
