Wondering how long does a bathroom renovation take? There isn’t one fixed answer. A straightforward bathroom renovation may take around 2 to 4 weeks once construction begins, while larger or more complex projects can take longer.
The timeline depends on what you’re changing, whether the plumbing layout is staying the same, how quickly materials are available and how well the different trades are coordinated. Recent Melbourne renovation guidance also places many standard bathroom renovations within the 2–4 week range.
For Melbourne homeowners, understanding what happens at each stage can make it easier to plan your renovation and prepare for the time your bathroom will be out of use.
How Long Does a Bathroom Renovation Take?
For a typical bathroom renovation, you can generally allow 2 to 4 weeks for the construction work.
A simple renovation with minimal layout changes may be completed towards the shorter end of that timeframe. A full renovation involving new plumbing locations, extensive tiling, custom fixtures or unexpected problems can take longer.
It’s also important to distinguish between planning time and construction time. Choosing fixtures, finalising the design and ordering materials can happen weeks before the physical renovation starts.
Once work begins, the process may include:
- Demolition and removal
- Plumbing and electrical work
- Wall and floor preparation
- Waterproofing
- Tiling
- Painting
- Fixture installation
- Plumbing fit-off
- Final finishing work
The trades don’t necessarily work continuously every day. Some stages require drying or curing time, while others depend on another trade finishing first.
What Happens During a Bathroom Renovation?

1. Planning and Preparation
Time required: Several days to several weeks
Before demolition starts, you’ll need to decide what you want from the new bathroom.
This may include choosing:
- Bathroom layout
- Toilet and basin
- Shower or bath
- Vanity
- Tapware
- Tiles
- Shower screen
- Lighting
- Storage
This stage can take longer than expected if decisions haven’t been finalised or products aren’t available.
Getting the plumbing requirements considered early is also important, particularly if you’re changing the position of your toilet, shower, basin or other fixtures.
2. Demolition
Time required: Around 1–2 days
Once everything is ready, the existing bathroom can be stripped out.
This may involve removing:
- Old tiles
- Vanity
- Toilet
- Shower
- Bath
- Fixtures and fittings
Demolition can also reveal problems that weren’t visible beforehand, such as damaged flooring, deteriorated plumbing or moisture-related issues.
3. Plumbing and Electrical Rough-In
Time required: Around 1–3 days
This is where much of the behind-the-wall work happens.
If you’re keeping the existing layout, the plumbing work may be relatively straightforward. However, moving fixtures can require additional pipework and drainage modifications.
Electrical work may also take place during this stage for lighting, exhaust fans, power points and other fittings.
The exact timeframe depends on the complexity of the renovation and how much of the existing installation can be reused.
4. Wall and Floor Preparation
Time required: Several days
Once the plumbing and electrical work is ready, walls and floors need to be prepared for waterproofing and finishes.
Depending on the bathroom, this may involve installing new wall linings, levelling surfaces or making other necessary repairs.
Proper preparation matters because problems underneath the finished surfaces can be much harder and more expensive to address later.
5. Waterproofing
Time required: Several days, including curing time
Waterproofing is one of the most important stages of a bathroom renovation.
Wet areas need to be properly prepared and waterproofed before tiling begins. The waterproofing system also needs sufficient time to cure according to the product and installation requirements.
This is one reason a bathroom renovation shouldn’t be rushed simply to meet an arbitrary deadline.
6. Tiling
Time required: Several days to around a week
Tiling can be one of the more time-consuming stages, particularly if you’re using large-format tiles, intricate patterns or extensive wall tiling.
The timeframe can depend on:
- Bathroom size
- Tile size
- Layout
- Number of tiled surfaces
- Cutting requirements
- Grout and adhesive curing times
Once tiling is complete, additional time may be required before other fixtures can be installed.
7. Installing Fixtures and Finishing
Time required: Several days
The final stage brings the bathroom together.
Plumbers may return to install and connect:
- Toilet
- Vanity
- Basin
- Tapware
- Shower
- Bath
- Other plumbing fixtures
Other trades may also install the shower screen, mirrors, lighting and finishing elements.
At this point, the bathroom can be tested to make sure the fixtures, drainage and water connections are operating correctly.
What Can Make a Bathroom Renovation Take Longer?

Changing the layout
Keeping your existing plumbing locations can simplify the renovation. Moving the toilet, shower or basin can require additional plumbing and drainage work, which may add time.
Waiting for materials
A renovation can stop if an essential fixture, tile, vanity or shower screen hasn’t arrived.
Custom-made products can also have longer lead times than standard options.
Unexpected plumbing problems
Once walls and floors are opened up, the existing plumbing may not always be in the condition you expected.
Old or damaged pipes, drainage problems or previous installation issues may need to be addressed before the renovation can continue.
Waterproofing and drying times
Some stages simply cannot be rushed. Waterproofing, adhesives, grout and other products need appropriate curing or drying time before the next stage can begin.
Trade availability
Bathroom renovations involve multiple trades, including plumbers, electricians, waterproofers, tilers and other specialists. If one trade isn’t available when needed, the entire schedule can be pushed back.
Can You Speed Up a Bathroom Renovation?
You can’t eliminate every delay, but good preparation can help keep the project moving.
Before work starts:
- Finalise your bathroom layout.
- Choose your fixtures and fittings.
- Confirm tile selections.
- Check product availability.
- Discuss plumbing changes early.
- Make sure trades are scheduled in the correct order.
- Avoid changing the design once construction has started.
Having the important decisions made before demolition begins can reduce unnecessary gaps between stages.
Does Changing the Plumbing Make a Renovation Take Longer?
It can.
A cosmetic update where the toilet, shower and basin remain in their existing positions is generally less involved than completely changing the bathroom layout.
For example, moving a toilet may require changes to the drainage system, while relocating a shower or basin may require new water and waste connections.
If you’re considering changing the layout, it’s worth discussing the plumbing requirements before you finalise the design.
FAQs About Bathroom Renovation Time
How long does a bathroom renovation take?
A typical bathroom renovation can take around 2 to 4 weeks once construction starts. More complex renovations involving layout changes, custom products, extensive tiling or unexpected problems may take longer.
How long does a small bathroom renovation take?
A small and relatively straightforward bathroom renovation may take around 2 to 3 weeks, depending on the work involved. The size of the room is only one factor; plumbing changes, materials and trade availability can also affect the timeline.
What takes the longest during a bathroom renovation?
There isn’t always one single longest stage. Waterproofing and curing, tiling, custom products and coordinating multiple trades can all affect the overall schedule.
Can I stay in my home during a bathroom renovation?
Yes, in many cases. However, the bathroom being renovated will generally be unavailable during construction. If it’s your only bathroom, you’ll need to make alternative arrangements.
Does moving a toilet increase renovation time?
It can. Moving a toilet may require changes to the existing drainage and plumbing, making the project more involved than simply replacing the existing fixture.
What usually causes bathroom renovation delays?
Common causes include unavailable materials, changes to the design, unexpected plumbing or structural problems, waterproofing and drying times, and gaps between different trades.
Conclusion
So, how long does a bathroom renovation take? For a standard project, around 2 to 4 weeks of construction is a reasonable starting point, but the actual timeframe depends on the scope of work and how well everything is planned.
