Shower Regrouting Guide

Shower Regrouting: What It Can and Cannot Fix

Regrouting can refresh worn, stained or damaged grout when the tiled surface and substrate remain sound. A leaking shower needs assessment before cosmetic grout repairs are chosen.

Grout Is Not a Replacement for Waterproofing

Tiles, grout and surface sealers do not replace the waterproofing membrane beneath a shower. Regrouting alone does not repair a failed membrane or a leaking pipe. Damp walls, persistent leaks, loose tiles or repeated grout failure should be investigated first.

A Practical Regrouting Process

  1. Check the tiles and joints for movement or underlying damage.
  2. Remove the affected grout to the depth required for the replacement product without damaging tiles or the membrane.
  3. Clean and prepare joints according to the grout manufacturer's instructions.
  4. Install a suitable grout and clean the surface at the specified time.
  5. Use a suitable flexible sealant at movement joints and changes of plane.
  6. Allow the full curing period before using the shower. Seal only where the chosen grout manufacturer requires it.
