Tile Repair Starts With Whether the Substrate Is Stable
One cracked tile can result from impact, but repeated cracking, hollow sound or loose areas can indicate movement or failed bonding below the surface. The repair should identify that condition before new tile is set.
Waterproofing Problems Cannot Be Repaired With Grout Alone
Recurring moisture, soft substrate or leaks can require rebuilding the waterproofing layer or pan. Surface grout should not be used as a substitute for that work.
For base-related issues, see Shower Pan Installation.
Layout Matters Around Niches and Fixtures
Valve trims, shower heads, niches and benches create repeated cuts and alignment points. Tile layout should be planned so narrow slivers and awkward joints are minimized where practical.
Movement Joints Use Flexible Sealant
Corners and changes of plane can require caulk or other flexible sealant rather than hard grout. For grout-only deterioration on stable tile, use Grout Repair.
Matching Repair Tile Can Be Difficult
Older tile can be discontinued or vary by batch. A local repair may remain visually different even when the physical work is sound. The customer should know that limitation before removal starts.

Not when the water problem comes from failed waterproofing or the pan.
