I am renovating my Penthouse and applying new tiles on the older ones without removing them. However, Level in each room is different therefore there will level change at each room entrance. I have been suggested to use the granite like in door frames for the level change. However, I feel that looks old school. Can I use same tiles across even at level changes? (Please note, I am using same tiles across all the rooms and granite framing for all doors and windows). Kindly find attached photo to understand the scenario.
