Water getting in the back of tile...regrout?

R11 · 2021-12-28 22:27:55

Small amount of water running down back of shower,staining ceiling below it. Originally thought it was the sealant around the bath,stripped and resealed it but made no difference. On closer inspection I spotted this the grout on first time up from bath is cracked......so do I strip the grout out and reapply? Or use…

As a temporary fix you can scrape out and reapply the grout, but these types of failures normally point to a secondary cause - such as shower-tray movement, plaster-board dampness, adhesive failure or general wear & tear related issues.
If the tile is loose, remove it and assess the state of the adhesive and use this in consideration of the fix. If the wall/plasterboard is solid, reapply the tile with fresh water-proof/bathroom adhesive and re-grout.
