Regrouting a standard bathroom in Adelaide typically costs between $400 and $900, and a single shower recess on its own usually sits around $250 to $500. It is one of the cheapest ways to make a tired wet area look almost new, provided the tiles and the waterproofing beneath them are still sound.
This guide gives you realistic Adelaide price bands by room, explains what moves the number, and shows why regrouting is often the smart choice over a full retile. It sits within our Tile Repairs, Regrouting and Restoration in Adelaide guide.
Regrouting price bands by room
Regrouting is usually priced as a whole job rather than strictly per square metre, because so much of the cost is in the fiddly work of raking out the old joints. As a guide for Adelaide:
| Job | Indicative Adelaide cost | | --- | --- | | Shower recess only | $250 to $500 | | Standard bathroom (floor and walls) | $400 to $900 | | Large or ensuite plus main bathroom | $800 to $1,500 | | Kitchen splashback | $200 to $450 | | Laundry floor and splashback | $250 to $550 | | Tiled floor per square metre | $15 to $30/m2 |
These ranges assume standard cement grout and reasonable access. Epoxy grout, large-format tiles with fine joints, or heavy mould treatment push the figure up.
What drives the price up or down
Two quotes for the same room can differ by hundreds, and it nearly always comes down to a handful of things.
How much grout is removed
This is the single biggest factor. A full regrout means raking every joint back to a consistent depth before new grout goes in, which is slow, dusty work. A lighter refresh over sound grout costs less but does not last as long. Be clear about which one you are quoting, so you are comparing like with like.
Grout type
Standard cement grout is the most affordable. Epoxy grout costs more to supply and takes more skill to apply, but it is denser, more water-resistant and does not need sealing, which makes it worth considering for showers and splashbacks. If you want the new grout to stay looking fresh, ask about grout sealing cost in Adelaide at the same time.
Mould and staining
Black mould in the joints has to be treated before regrouting, not painted over. That adds time, and in a shower that has been left too long it can hint at a bigger problem behind the tiles. If joints are crumbling or cracked rather than just discoloured, read cracked grout: repair or replace? before you spend anything.
Tile format and access
Large-format tiles with thin joints, mosaics with hundreds of tiny joints, and tight corners around taps and screens all add labour. A simple 300x300 floor is quick. A mosaic feature wall is not.
Why regrouting beats a full retile
Here is the part most homeowners get wrong. When grout looks tired, discoloured or patchy, it is easy to assume the whole wet area needs redoing. In most cases it does not.
The tiles themselves rarely wear out. It is the grout, the softer cement in the joints, that stains, cracks and lets moisture creep in. If your tiles are firmly stuck down and the waterproof membrane underneath is still doing its job, regrouting gives you a clean, fresh finish without tearing anything out.
The cost difference is stark:
| Option | Indicative Adelaide cost | | --- | --- | | Regrout a bathroom | $400 to $900 | | Full bathroom retile | $2,500 to $6,500 or more |
A full retile means removing tiles, redoing the waterproofing to Australian Standards, and laying fresh tiles, a multi-day job with real disruption. Regrouting is usually done in a day or 2 and costs a fraction of the price.
The key question is whether the waterproofing is still sound. If tiles are lifting, the floor feels spongy, or water is escaping the wet area, regrouting is only a cosmetic fix and you may need to go further. Our guide on regrout or retile? walks through exactly how to tell the difference.
When regrouting is not enough
Regrouting is the right call when:
- The tiles are firmly bonded and not cracked
- The waterproofing is intact and there are no leaks
- The grout is stained, patchy or has hairline surface cracks
- You want a fresh look without a full renovation
It is not enough when tiles are drummy or lifting, when there is active water damage, or when the membrane has failed. In those cases fresh grout just hides the problem for a while. A licensed tiler can tell you which situation you are in during the quote, which is why getting a professional to look before you commit is worth it.
