Yes - in shower re‑grouting and leaking shower repair, epoxy grout outperforms cement‑based grout in critical ways: it’s waterproof, stain‑resistant, mould‑proof, and far more durable once cured

Traditional cement grout stays porous unless regularly sealed.

Higher cost – roughly 2–3× the price of cement grout.

Fast initial set – it cures quickly, requiring precision and speed.

Difficult cleanup – any residue must be wiped before it hardens or it can permanently haze tiles.

Because of these factors, epoxy grout is best applied by experienced professionals during shower re‑grouting jobs.

Absolutely. Epoxy grout is ideal for wet environments like shower walls and floors because of its full resistance to moisture and mould. It’s widely recommended by tiling experts for these exact uses.

Yes and no:

Yes, if the leak is caused by cracked or missing grout lines, a full re‑grouting with epoxy can seal the tile joints and restore waterproofing above the tile.

No, if the root cause is a compromised waterproof membrane under the tiles - in that case, re‑grouting may fail until the membrane is repaired.

Definitely. Shower re‑grouting involves:

Removing old grout down to half the depth of the tile.

Cleaning the joints thoroughly,

Applying new epoxy grout,

Finishing with a final clean.

It’s a precise job that restores waterproof integrity and improves appearance.

Each shower is different - so expect cost to vary significantly.

Factors that influence price include the number of tiled walls, total tile area, tile size and format, whether the shower base is tiled, if there's a recessed niche, and the grout material used (epoxy vs cement, etc.).

In summary: expect standard shower re‑grouting in Melbourne to cost between $400 and $2,000, with most jobs normally in the $800–$1,400 bracket depending on size, accessibility, grout type, and job complexity.

If leaks are due to damaged grout or sealant, then yes - epoxy grout plus proper caulking often fixes the issue for over a decade.

If the underlying waterproofing is compromised, even epoxy grout won’t prevent leakage. The compromised waterproofing membrane would have to be addressed first.

First, determine whether the leak is due to grout failure or a cracked shower tray.

For small cracks in tile grout, start with re‑grouting or replacing the silicone joints.

If water is still going through to the ceiling or subfloor, the shower pan or waterproof membrane must be repaired or replaced urgently.

Not reliably. While sealing cement grout can slow moisture penetration for a while, it’s only temporary:

Cement grout still remains minimally porous unless rebuilt or replaced.

Epoxy grout as per manufactures instructions, never needs sealing and some claim it is 100% waterproof.

For leaks caused by worn grout or cracked caulk:

Opt for The Grout Co, full shower re‑grouting with epoxy grout, combined with new silicone sealing on edges and joints

If leak persists below tiles:

Expect to inspect and possibly replace the shower base or re-waterproof the shower area, especially if the original membrane was poorly installed or not installed to begin with.

Not directly. You must remove old grout to at least half the depth of the tile. clean the joints fully, then install fresh epoxy overlay. Overlaying epoxy over cement can cause delamination or visual issues down the track.
