Urgency
2/5
Honest verdict: this one's worth a pro$200–$800Typical repair cost
Likely causes, most common first
- Mastic failure from heat/steam near the range
- Tile set over wallpaper, paint, or grease — bond never had a chance
- Wall movement or moisture behind the sink section
Do this right now
- Remove fully loose tiles before they fall and chip
- Save every intact tile — matching discontinued tile is the hard part

Re-setting a section properly means cleaning the wall to sound surface and using the right setting material for the zone. If more than a few tiles release, the field was badly set — re-doing the splash is often smarter than chasing failures.
