An idea to fix a broken tile area. Don't tear out the wall of tile, make light of it! Caulk the broken/missing tile to waterproof, then add an air fern (kitchen backsplash) or a fake plant (shower or tub area).
If you've never been to Istanbul, Iznik tiles are amazing ceramic designs from the ottoman empire, and there are so many amazing patterns. My visit to Istanbul still influences my style so much. Iznik tile decoration - The Harem, Topkapi Palace
