Hi! Our bathrooms have 90s tiling which includes a strip of feature tiles (as well as a couple of single accent tiles) which have raised portions to create designs of hibiscus flowers. I'd really like to just paint over the tiles for a simple refresh, but don't want these designs. As they're raised (not etched) I can't fill them in with an epoxy or similar. I'm assuming I shouldn't sand/grind them back either because of the risk of silicosis? Waterproof wall panels could be an option; however would introduce extra work as I'd need to adjust the door frame as currently tiles sit almost flush with it and covering them would create a difference of about 10mm.
I'm just wondering if there's any other options for me that I haven't considered? I want to avoid removing the tiles as I don't want the expense of re-waterproofing.
