Bathroom renovation cost in Cranbourne
What a bathroom costs in postcode 3977, band by band, the measured rates behind each band, and the six things that push a Cranbourne job up to the next one.
A bathroom in Cranbourne is priced by what sits behind the existing wall sheet and under the floor, rather than by the tapware on the wish list. Postcode 3977 runs from the 1860s township out through 1990s Cranbourne West to Cranbourne East estates that were market gardens and paddocks twenty years ago. That spread is why two houses four kilometres apart can be quoted twenty thousand dollars apart for a room that ends up looking much the same. This page sets out the bands, the rates underneath them, what specifically pushes a job here up a band, and how to put three written quotes side by side without comparing the wrong numbers.
What do the bands cover?
| Job | What that scope usually includes | Band |
|---|---|---|
| Small or budget full bathroom | Same layout, prefabricated or standard base, ceramic tiles to a set height, mid range fitout | $10,500 to $21,000 |
| Standard full bathroom | Same footprint with minor fixture moves, custom set down base, floor to ceiling tiling, better tapware, heated towel rail and a decent fan | $21,000 to $36,750 |
| Large or high end bathroom | Layout changed, large format or stone tiling, freestanding bath, wall mounted or floor mounted mixers, joinery vanity | $36,750 to $57,750 |
| Ensuite | A compact second wet area, either an existing builder spec ensuite rebuilt or a new one carved out of adjoining space | $14,000 to $25,000 |
| Separate toilet or powder room | The standalone WC that came with most township and 1990s floor plans | $6,000 to $14,000 |
| Laundry | Anything from a cupboard refit to a full rebuild with new joinery and a relocated trough | $5,000 to $20,000 |
Where a house sits in the postcode is a fair predictor of the band. Township and Cranbourne West jobs mostly land in the first two rows, because the rooms are small, the layouts are fixed and local budget expectations sit below the eastern side of Casey. Cranbourne North and Cranbourne East owners usually want a main bathroom in the standard row and an ensuite upgrade alongside it. Botanic Ridge, Settlers Run and Sandhurst briefs move into the top row as soon as a freestanding bath and large format tiling are on the list.
The rates that build the total
A fixed price quote is assembled from measured quantities, so these are the numbers that produce the total.
| Item | Rate |
|---|---|
| Wet area waterproofing, supplied and applied | $50 to $85 per m2 |
| Wall tiling, supply and lay | $75 to $165 per m2 |
| Floor tiling, supply and lay | $90 to $190 per m2 |
| Shower screen, frameless or semi frameless, installed | $1,200 to $3,500 |
| Vanity supplied and installed | $500 to $3,700 |
| Freestanding bath supplied and installed | $1,600 to $5,300 |
Tiling is the largest single line on most jobs because a floor to ceiling bathroom carries a surprising amount of wall area. A modest three by two metre room with walls tiled to the ceiling is around thirty square metres of wall, which is why a tile selection that looks like a small upgrade per square metre can move the total by a few thousand dollars.
What pushes a Cranbourne job up a band?
- Asbestos. On any house here built before 1990, sampling comes first and the laboratory result decides whether a removal allowance sits on top of the band. In the old township, Junction Village and Devon Meadows, price the job expecting a positive result rather than hoping for a negative one. Who is allowed to take the samples and do the removal is covered by what the law requires.
- Finding a second wet area. In a one bathroom township house the brief is often to create an ensuite out of a bedroom corner, the hallway linen or part of the laundry. New drainage, a new vent, an exhaust path to outside and a building surveyor all arrive with that decision.
- Repeat grout failure on moving ground. Soil that swells and shrinks with the seasons shears silicone and splits grout lines, and a shower already regrouted twice needs rebuilding rather than a third attempt. That is a full band above a patch, and the symptoms are described on signs your shower is leaking.
- Tile format. Large format tiles need a flatter substrate, more setout time, more cutting waste and often a levelling screed, so the labour rises with the tile size.
- Tapware in the wall or the floor. A wall mounted set or a floor mounted bath mixer has to be roughed in before sheeting, and the pipework and support framing add cost and remove the option of changing your mind later.
- Structure and access. Taking out a loadbearing element, changing the floor area or underpinning turns the job into permit work with a surveyor involved. On the access side, most township blocks take a skip in the driveway, while court bowls and narrow frontages in the newer estates often mean bin swaps or a City of Casey permit, with fees current at the time of writing.
How do you compare three quotes?
Quotes for the same bathroom can differ by more than a third without either party being unreasonable, because they are pricing different scopes. Compare these lines before comparing totals.
| Check | What you are looking for |
|---|---|
| Asbestos | Is sampling included, and is removal priced or excluded and left as a variation |
| Waterproofing | Is the membrane applied to the standard with the certificate handed over, and is the wall height stated |
| Screed and falls | Is a new screed included, or is the quote assuming the existing falls are reusable |
| Tiles | Is there a supply allowance per square metre, and what happens if you pick above it |
| Tapware and fixtures | Supply allowance or supplied by you, and whether installation of your own items is included |
| Plumbing | Who issues the compliance certificate, and whether relocating the waste is in or out |
| Electrical | Is the safety certificate included, and are new circuits allowed for |
| Rubbish | Skip or bin swaps, and who pays any council permit |
| Variations | Is there a written process, and are rates for extra work stated up front |
| Payment | How much is wanted up front, and what stages the rest is attached to |
Two quotes with the same total can be five thousand dollars apart in real terms once asbestos and drainage sit inside one and outside the other. The registration and contract questions that go with this are on choosing a bathroom renovator.
What can be asked for before work starts?
Money wanted before the first day is capped in Victoria, and the cap steps down once the contract price passes a set figure, so check what a quote asks of you against what the law requires before you transfer anything. The rest of the money should be attached to stages you can see finished, with the balance held until handover.
How long the money is tied up
Price and program move together, because a room that is open for longer costs more to run and holds up the rest of the house. The trade by trade sequence for each of these scopes, and the things that stretch it, are on how long a bathroom renovation takes.
