It’s one of the first things people ask when planning to transform their space. Whether you’re tackling a small bathroom or going all out with a full bathroom renovation, knowing the time frame helps set realistic expectations.
On average, a bathroom renovation takes anywhere from 3 to 8 weeks.
The timeline can vary depending on the renovation process, project scope, and whether you’re making structural changes or keeping the layout of your existing bathroom.
So, let’s break it all down. By the end of this guide, you’ll know what to expect from every phase of the renovation, how to plan ahead, and how to avoid delays.
Quick Summary
- Bathroom renovations typically take 3–8 weeks, depending on project scope, structural changes, and material availability. Smaller projects can be completed in 3–4 weeks, while larger, more complex renovations may take 6–8 weeks.
- Renovations include five main phases: planning (2–6 weeks), demolition and preparation (1–2 weeks), construction (2–3 weeks), installation (1–2 weeks), and finishing touches (1 week). Each phase contributes to the overall timeline.
- The duration can be influenced by the project’s scope, structural changes, material delays, and whether it’s DIY or professionally managed. Proper planning, timely material sourcing, and clear communication with contractors help avoid delays.
Understanding the Average Bathroom Renovation Timeline
For an average bathroom renovation, the time frame typically looks like this:
- Smaller projects: Around 3 to 4 weeks
- Larger renovations: Between 6 to 8 weeks
Why the range?
It all depends on what you’re doing. A simple “pull-and-replace” project for an old bathroom is quick, while a new bathroom with custom built vanities, heated flooring, or structural work can take longer.

Breaking Down the Bathroom Renovation Process
Every bathroom renovation has five main phases: planning, demolition, construction, installation, and finishing touches.
Let’s take a closer look.
Planning Phase (2–6 Weeks)
This is where everything starts. The planning phase might not seem like “real work,” but it’s crucial to a smoother renovation process. Tasks in this phase include:
- Designing your bathroom
Decide on your bathroom style and layout. Will you keep the existing fittings or go for a completely new bathroom design?
- Obtaining permits
Structural changes or drainage underfloor work often require planning permission from your local council. Depending on your area, this can take 2–4 weeks.
- Sourcing materials
Custom-built vanities, shower screen, and specialty tiles might take longer to arrive, so order them early.
- Hiring contractors
Book professionals for plumbing, electrical work, tiling, and carpentry.
During this phase, it’s all about preparation. Rushing through it often leads to delays later.
Demolition and Preparation (1–2 Weeks)
Once the planning is sorted, it’s time to say goodbye to the old bathroom. This phase is messy but necessary. Here’s what happens:
- Demolition (1–2 days)
Contractors remove old fixtures, tiles, and flooring. If your bathroom needs structural work, like moving walls or changing drainage underfloor systems, expect this to take longer.
- Jobsite protection
Covering nearby rooms to minimise construction debris.
- Plumbing and electrical rough-ins
Plumbing and electrical systems are prepped for new fixtures. This typically takes 2–3 days and must meet Australian standards.
Inspections are usually required before moving forward, so factor in a day or two for that.
Construction Phase (2–3 Weeks)
Here’s where your dream bathroom starts taking shape. The construction phase includes:
- Subfloor and waterproofing (2–3 days)
This is especially important in wet areas like showers. Waterproof barriers ensure a fully functioning bathroom.
- Tiling (5–7 days)
Wall and floor tiles are installed. Intricate designs or larger tiles take longer.
- Structural replacements (if needed)
Moving walls, adjusting the layout, or adding new features like a heated towel ladder adds time.
Patience is key during this stage. A well-done construction ensures fewer issues down the line.
Installation Phase (1–2 Weeks)
The most exciting part! This phase is when your bathroom starts looking like… well, a bathroom.
- Installing floor tiles and fixtures (3–5 days)
Fixtures like shower doors, vanities, and extractor fans are added.
- Light fittings and electrical items (1–2 days)
Electrical work includes connecting light switches, heated flooring, and more.
- Plumbing work
New plumbing is connected for sinks, toilets, and showers.
Smaller bathrooms or simple bathroom fittings may only take a few days, while a full bathroom installation could stretch closer to two weeks.
Finishing Touches and Post Construction Phase Cleaning (1 Week)
The final week is all about tying up loose ends:
- Painting and trim work (1–2 days)
Adds those style features that bring everything together.
- Final walkthrough and inspections
Contractors address any issues, ensuring your bathroom meets expectations.
- Post-construction cleaning
Construction rubble is cleared, leaving the space ready to use.
Once this phase is complete, your bathroom renovation is done, and your dream bathroom is a reality.
Key Factors That Affect Bathroom Renovation Time
Not all renovations are the same. Here are some factors that can impact how long your bathroom renovation takes:
- Project scope
A full bathroom renovation naturally takes longer than refreshing a small bathroom with new fixtures.
- Structural changes
Moving walls or plumbing systems adds significant time.
- Material delays
Items like custom vanities or imported tiles can push back timelines if not ordered early.
- DIY vs. professional work
Doing it yourself saves money but often takes more time, especially for complex processes like tiling or plumbing and electrical work.
Tips to Avoid Unnecessary Delays
No one likes delays. Here’s how to avoid them:
- Plan ahead: Finalise your bathroom design and source materials early.
- Stick to decisions: Changing bathroom style or fittings mid-project adds time.
- Communicate with contractors: Clear communication prevents misunderstandings.
Proper planning ensures a smoother renovation from start to finish.
What About Smaller Renovations?
If you’re working with small bathrooms or simply replacing old fixtures, the timeline is shorter.
A quick bathroom renovation might look like this:
- Week 1: Demolition and rough-ins for plumbing and electrical.
- Week 2: Tiling and installing floors.
- Week 3: Final installations and finishing touches.
Even simple projects require planning, but they’re far less disruptive than a bathroom renovation.
Setting Realistic Expectations
Bathroom renovations aren’t just an inconvenience; they’re an investment in one of your home’s most important rooms.
While the complex process might feel slow at times, taking the necessary steps ensures your renovation experience is positive. Remember, even small delays can happen due to inspections, drying time for tiles, or waiting for fixtures to arrive.
By the end, though, you’ll have a fully functioning bathroom that meets your needs and matches your style.
