Thank you for your review of our tiles! We are happy to see that our Genesis Icon Coffer Lay In Tiles were able to complete your installation. We do not recommend cutting our Icon Coffer style panels, rather, we recommend using our Designer Series Border tile to border the perimeter of your room for a more polished, finished look. If you have any additional questions, feel free to reach out to our customer care team at 800.434.3750. Thanks again!
