One of the first questions homeowners ask when planning a bathroom renovation is how long the whole process will take. The answer depends on the scope of work, the condition of the existing bathroom and how well the project is planned before trades arrive on site.
For most standard bathroom renovations across Melbourne’s northern and eastern suburbs — from Eltham and Greensborough to Doncaster and Templestowe — you can expect the build phase to take between two and four weeks. However, the full timeline from initial planning to completion is often longer than people anticipate.
1. Planning and design: two to six weeks
Before any demolition begins, a well-managed renovation starts with a detailed plan. This phase includes an initial consultation and site measure, design discussions covering layout, fixtures and finishes, material selection for tiles, tapware, vanity and accessories, and obtaining any necessary building permits.
Taking time at this stage avoids costly changes mid-build. Rushing the design phase is one of the most common reasons renovations blow out in both time and budget.
2. Demolition and strip-out: one to two days
Once the plan is locked in, the existing bathroom is stripped back. This involves removing old tiles, fixtures, vanity, shower screen and any damaged substrate. For older homes in suburbs like Montmorency, Rosanna and Bundoora, this stage can sometimes reveal hidden issues such as damaged framing, corroded plumbing or failed waterproofing that need to be addressed before new work begins.
A reputable renovator will always allow time in the schedule for potential discoveries during demolition rather than assuming everything behind the walls is in perfect condition.
3. Plumbing and electrical rough-in: one to three days
With the room stripped back, the plumber and electrician carry out their rough-in work. This includes relocating or installing new water supply and waste pipes, positioning outlets for heated towel rails, exhaust fans and lighting, and installing underfloor heating if specified.
If you are keeping the existing layout, this phase is quicker. Moving a toilet, shower or vanity to a new position adds time due to additional plumbing runs and potential floor-level adjustments.
4. Waterproofing: one to two days plus curing time
Waterproofing is applied to all wet areas in accordance with Australian Standard AS 3740. The membrane typically requires two coats with drying time between each, followed by a curing period before tiling can begin. Your waterproofer will issue a compliance certificate before the next stage proceeds.
This is not a step that can be rushed. Inadequate curing time is a leading cause of waterproofing failure, so expect at least 24 to 48 hours for the membrane to fully cure depending on the product used and weather conditions.
5. Tiling: three to five days
Tiling is usually the longest single phase of the renovation. The time required depends on the size of the bathroom, the tile format (large-format tiles require different preparation than mosaics), the complexity of the layout including niches, feature walls and borders, and whether floor-to-ceiling tiling is specified.
After tiles are laid, grout needs time to set before the room can be used. Allow at least 24 hours before any fixtures are installed on tiled surfaces.
6. Fixture installation and fit-off: one to two days
The final stage brings the bathroom together. The vanity, basin and tapware are installed, the toilet is connected, the shower screen is fitted, mirrors, accessories and towel rails are mounted, and a final plumbing and electrical check is completed.
A thorough final clean and quality inspection should follow before handover. At Aqua Force Bathrooms, we walk through the completed renovation with every client to ensure everything meets expectations.
What can cause delays?
Even well-planned renovations can encounter setbacks. The most common causes of delays include:
Unexpected structural or plumbing issues discovered during demolition
Tiles or fixtures on back-order or delayed in shipping
Weather affecting waterproofing curing times
Changes to the design or material selections mid-project
Scheduling conflicts between trades
Choosing a renovator who manages all trades in-house or coordinates them closely significantly reduces the risk of scheduling delays.
