Shower Regrouting Before and After: Real Melbourne Jobs
Every shower below is a real Groutix job in a Melbourne home. No stock photos and no filters. Drag the slider on each photo to compare before and after, and see what removing failed grout and rebuilding with waterproof epoxy actually does.
Cracked, Crumbling Grout, Rebuilt With Waterproof Epoxy
This shower floor had done what cement grout always does in a wet area: cracked, crumbled and started letting water through to whatever sits below. We removed every line of the failed grout and rebuilt the floor with waterproof epoxy, so the joints are sealed and made to flex with the tiles instead of cracking again. The tiles never moved.
Mould That Kept Coming Back, Fixed at the Source
Scrubbing this corner shower only ever bought a few clean weeks, because mould lives inside porous grout, not on the surface. The failed grout came out completely and the shower was regrouted and resealed, removing the damp trap the mould was feeding on. That is the difference between cleaning mould and actually fixing it.
A Leaking Shower, Repaired Without Removing Tiles
Water was escaping through failed grout and silicone, the kind of slow leak that quietly damages walls, floors and the ceiling below before anyone notices. We repaired the joints and resealed the shower with waterproof epoxy, stopping the leak at its source. No tiles removed, no renovation, no drama.
Left too long, failed grout lets water damage what sits behind and beyond the bathroom: wall framing, floors and the ceiling below. A musty smell that never quite leaves is often the first hint. If you already have damp walls or ceiling stains, see our leaking shower repair page.
Why Grout Fails
What Causes Shower Grout to Fail in Melbourne Homes?
Grout is not decoration. It works with the waterproof membrane under your tiles to keep water where it belongs. Once grout cracks or turns porous, water ingress begins: moisture travels behind walls and under floors, feeding mould and musty odours long before a stain ever shows.
Melbourne’s Weather
Warm days and cold nights make tiles move slightly. Cement grout cannot flex with that movement for long. It cracks, and water gets in.
Why epoxy handles movement →Older Bathrooms
Many homes in suburbs like Malvern, Toorak and Camberwell have bathrooms that are decades old.
Regrouting an older bathroom →Wet Area Standards
Some were built before Australian Standard AS 3740 tightened the rules for wet area waterproofing. In those showers, the grout and silicone do more of the work than they should.

Why Surface Fixes Don’t Last
Smearing fresh silicone over old grout, or painting on a grout sealer, only masks the failure underneath. The cracked, porous grout keeps letting water through, so the mould, odours and leaks return, usually within months. The lasting fix is to remove the failed grout completely and rebuild the joint so the shower is watertight again.
Choosing Grout
Epoxy Grout vs Cement Grout
Most showers use one of two grout types. The difference matters.
| Feature | Cement grout | Epoxy grout |
|---|---|---|
| Water resistance | Porous, absorbs water over time | Non porous, built for wet areas |
| Mould resistance | Weaker, mould can grow in the pores | Stronger, nothing to hold moisture |
| Flexibility | Can crack with movement | Handles movement better |
| Best for | Dry areas like splashbacks | Showers and wet areas |
Cement grout soaks up water, soap and dirt. Mould then grows in those pores, even when you clean often.
Epoxy grout is a resin. It does not absorb water. It costs more to install and takes more skill to apply, but it is made for constant moisture. That is what restores your shower’s waterproof integrity, sealing the grout lines where leaks start. Learn more on our epoxy grout page.
Why a Rushed Cement Regrout Fails Again
Cement grout works well in dry spots. It was never built for daily water contact. A quick cement regrout in a shower often looks fine for a while, then cracks and discolours again.
Why Isn’t Epoxy Used More Often?
Epoxy is harder to apply and sets faster, so it needs more experience to finish cleanly. Some tradespeople stay with cement because it is quicker for them, not because it suits your shower.
Older Homes
Can You Regrout an Old or Original Bathroom?
Yes, in Most Cases
Age alone does not rule it out. The condition underneath matters.
Tiles Stay, Grout Goes
If your tiles are solid and the membrane has not failed, regrouting works on a bathroom from any decade. The tiles stay. Only the grout and silicone are replaced.
We Check First
If the membrane has failed, regrouting will not fix that for long. We check before we quote.
Honest Advice
Regrout, Retile or Rebuild?
Not every shower needs the same fix. A good tradesperson tells you the truth, not the biggest job.
Tiles solid, membrane intact
The problem sits in the grout or silicone. This covers most jobs we see.
Cracked, chipped or hollow tiles
Individual tiles are cracked, chipped or sound hollow when tapped. A hollow sound can mean the tile has come loose.

Water has been getting through. Regrouting cannot fix that. It only delays the problem.
Our Process
Our Regrouting Process
Every job starts with understanding what’s actually happening, not a quick surface fix. The exact work can vary depending on the condition of your shower.
- 01
Assess the Shower
We inspect the grout, silicone and surrounding tiles before recommending any work.
- 02
Remove and Prepare
Damaged grout and old silicone are fully removed, including the wall junctions and floor joints where showers usually fail first, and the area is prepared. The amount of work depends on what we find.
- 03
Regrout and Finish
New grout and sealant are applied and finished so the surface is sealed properly again.
- 04
Cure and Warranty
Your shower is ready to use once the grout and silicone have cured.
Eligible complete shower regrouting work is backed by a 10 year waterproof warranty.

DIY
Is DIY Shower Regrouting Worth It?
DIY can work for a small job with no deeper damage. Most DIY jobs fail for the same reasons:
Old Grout Left Behind
Old grout is left in the joint, so mould grows back through the new grout.
Wrong Grout Type
Cement grout is used in a shower, where it was never meant to last.
Used Too Soon
The shower is used again before the grout and silicone have cured.
If you see damage past the grout, such as a stain on a ceiling below, get a professional to check first. Regrouting over a hidden leak only hides it for a while.
