Regrouting refreshes a tired shower and improves its water resistance for a fraction of re-tiling. But if the shower leaks, the waterproofing membrane behind the tiles may have failed, which regrouting cannot fix.
Ways to save
- Regrouting is far cheaper than re-tiling if the tiles are sound and only the grout has failed.
- Upgrade to epoxy grout for a wet area, it resists mould and lasts much longer.
- If the shower is genuinely leaking into the wall, address the waterproofing, regrouting alone will not stop it.
How we estimate this
Regrouting a shower in Australia typically costs around $300 to $600 in 2026, with a silicone reseal cheaper and a full regrout plus leak treatment higher. It is a fraction of the $3,000+ cost of re-tiling.

What a shower regrouting costs in Perth
The price of regrouting a shower in Perth comes down to the length of grout line to rake and refill, which follows the tile size and the shower's area, because small or mosaic tiles hold far more joint per square metre than large format tiles and take longer to work through. It is maintenance rather than a rebuild: the old grout is ground from the joints, the joints are cleaned, and new grout and a fresh silicone seal are applied, with the waterproofing membrane under the tiles left intact.
The dry Mediterranean climate works in Perth's favour here, because lower everyday humidity means grout mould tends to build more slowly than in the humid north, so an average Perth shower may carry lighter staining and need less heavy raking, though a poorly ventilated bathroom still grows mould in the joints over time. Regrouting suits a shower where the double-brick walls, tiles and membrane are sound and only the grout has failed, while lifting tiles or a damp patch on the far side of the wall point to a larger repair. The isolation of the WA market can add lead time for a specialist epoxy grout, which costs more than cement grout but resists mould better. Labour sits near the national average.
Regrouting and resealing a shower is tiling and finishing work, not a licensed building trade, so the grout needs no plumbing or building licence, though a leak that has reached the waterproofing makes the repair licensed waterproofing and tiling work, and any tapware change is a licensed plumber's job under WA Building Services. For a Perth bathroom, the clearest way to price regrouting is by the grout-line length and tile size, with the dry climate often meaning lighter mould than the humid states.

Frequently asked questions
How is shower regrouting priced in Perth?
By the length of grout line to rake and refill, which follows the tile size and shower area, because small or mosaic tiles hold far more joint per square metre than large tiles and take longer to work through in a Perth bathroom.
Does Perth's dry climate help with regrouting?
Yes. The dry Mediterranean climate and lower everyday humidity mean grout mould builds more slowly than in the humid north, so an average Perth shower may carry lighter staining and need less heavy raking, though a poorly ventilated bathroom still grows mould over time.
When is regrouting not enough in Perth?
When tiles are lifting or a damp patch shows on the far side of the wall, which point to a larger repair, whereas regrouting suits a Perth shower where the double-brick walls, tiles and membrane are sound and only the grout has failed.
Do I need a licence to regrout in Perth?
No. Regrouting and resealing is tiling and finishing work, not a licensed building trade, though a leak that has reached the waterproofing makes the repair licensed waterproofing and tiling work, and a tapware change is a licensed plumber's job under WA Building Services.
