I live in Great Britain and hope you are happy to help . I would like to achieve this effect around bathroom door . Is architrave fitted after tile ? How wide and thick is it . Is it part of frame inside door or applied separately. I am having a barn door and not a pocket door but if have wood frame inside doorway this would allow a very neat transition from tiles to plastered wall in bedroom. my bathroom is contemporary . I would very much appreciate any help as I am pulling my hair out trying to find a solution
