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).
You can't really tell if this beauty actually is a greenhouse or maybe a gigantic indoor garden. But either way it is stunning and a huge inspiration on how to design one's one greenhouse with a little more charm than just the usual pots and benches.
