Hello Dre,

Thanks for your message, and your interest in Motawi Tileworks! It appears that these tiles were recessed into the custom millwork, and we would recommend adhering them in this application using Liquid Nails. I hope that this helps, but please let me know if we can be of further assistance!

Thank you so much for this information! I purchased two Motawi tiles through a tile vendor and look forward to having them installed like this!
