Grout might not be the most glamorous part of your bathroom—but it plays a crucial role in keeping your shower watertight, clean, and structurally sound. Over time, grout wears down, cracks, and discolours—opening the door for leaks, mould, and water damage.
If you’re wondering whether it’s time to replace your shower grout, here’s what you need to know—and why acting early can save you from major repairs later on.
How do you know when it’s time to replace your shower grout?
✅ Cracks and gaps in grout lines
Small cracks may seem harmless, but they allow water to seep behind tiles and into the wall or floor beneath. Over time, this can lead to swelling, rot, and structural issues.
✅ Mould that keeps coming back
Persistent mould or mildew, especially in grout lines and corners, is often a sign that your grout is holding moisture or failing to protect the area.
✅ Stained or crumbling grout
If your grout looks permanently stained, flaky, or is crumbling when touched, it’s likely past its prime and no longer doing its job.
✅ Loose or shifting tiles
Water getting behind your tiles can weaken the adhesive and cause them to move or lift—a clear sign of grout and seal failure.
Why grout replacement matters
Shower grout isn’t just cosmetic. It seals the gaps between tiles to prevent water infiltration. When it fails, your waterproofing system is compromised—and that’s when the real damage begins.
Replacing old grout helps:
- Restore waterproofing
- Prevent leaks and water damage
- Improve bathroom hygiene
- Refresh your bathroom’s look instantly
- Extend the life of your shower
Don’t forget the silicone
In many cases, shower grout replacement should be paired with silicone removal and resealing. Silicone is used to seal the joints between walls and floors—and if it’s mouldy or peeling, it can undo all your grout work by allowing water through.
