How long does a bathroom renovation take? It is one of the first questions we hear from Gold Coast homeowners, and the honest answer is that it depends on the scope of your project. Most standard bathroom renovations take around three to four weeks on site, from the first day of demolition through to handover, with larger or more complex bathrooms running closer to five or six weeks. On top of that, allow one to three weeks for design and planning before any work begins.
The good news is that a bathroom renovation follows a predictable sequence. Once you understand what happens each week, the timeline stops feeling like a mystery and starts feeling like a plan. In this guide we walk you through a realistic week-by-week bathroom renovation timeline, explain the stages that cannot be rushed, and share what tends to add time. Whether you are refreshing a compact ensuite or transforming a large family bathroom, here is what to expect.
The Short Answer: How Long Does a Bathroom Renovation Take?
For most Gold Coast homes, a full bathroom renovation takes three to four weeks of on-site work. Cosmetic updates that keep the existing layout can wrap up in two to three weeks, while large bathrooms with custom cabinetry, feature tiling or a relocated layout can stretch to five or six weeks. The Housing Industry Association estimates a full bathroom installation averages around 25 working days, and those days are not always back to back. Natural pauses are built into the process, such as waiting for waterproofing to cure or tile adhesive to set.
Add design, selections and ordering beforehand, and the complete journey from first consultation to finished bathroom usually spans six to ten weeks. Timeline and budget go hand in hand, so it is worth reading our guide on how much a bathroom renovation costs alongside this one.
Before the Build: Design, Selections and Planning
The build itself is only part of the story. The weeks before demolition are where a smooth renovation is won or lost. During this stage you finalise your design and layout, choose every tile, tapware, vanity and fixture, and lock in your quote. If you are working with a custom cabinetry team, your vanity and joinery are measured and put into production now.
This planning phase typically takes one to three weeks, and can run longer if selections are left open or custom items have long lead times. The single biggest cause of on-site delays is unfinished selections: a plumber needs the exact mixer model before rough-in, and a tiler needs your tiles on hand before they can start. Locking these decisions in early is the best thing you can do to keep your bathroom renovation on schedule. You can see how we guide clients through this stage in our renovation process.
Week 1: Demolition and Rough-In
Week one is the most dramatic. Day one is usually strip-out: the old vanity, toilet, shower screen and bath are removed, and existing tiles are taken back to the bare wall and floor substrate. By the end of the first few days your bathroom looks like a construction site, which is completely normal.
Once the space is stripped, your plumber and electrician complete the rough-in. This is the behind-the-walls stage where new pipes, drainage and wiring are run to suit your new layout before anything is sealed up. Getting the rough-in exactly right matters, because moving plumbing after the tiles are laid is difficult and costly. This is also when older homes reveal their surprises, such as corroded pipes, hidden water damage or non-compliant sheeting. On the Gold Coast, any building work valued over $3,300 must be carried out by a QBCC licensed contractor, so this work is completed and checked to standard.
Week 2: Waterproofing and Wall Sheeting
With rough-in complete, new wet-area sheeting and plasterboard go up, and then comes the stage that protects your entire home: waterproofing. Under Australian Standard AS 3740, all wet areas must be waterproofed correctly, and once the membrane is applied it needs roughly 24 to 48 hours to cure before tiling can begin.
This cure time is not a delay, it is a non-negotiable hold point, and rushing it is the most expensive mistake in the whole project. The QBCC reports that waterproofing defects are among the most common and costly building complaints, with each residential bathroom claim under the Queensland Home Warranty Scheme averaging almost $25,000 in rectification costs. That is why a quality builder will never cut this stage short. A single pinprick in a poorly cured membrane can mean ripping up finished tiles later, so patience here saves you thousands down the track.
Week 3: Tiling and Grouting
Once waterproofing has cured and passed inspection, tiling begins, and this is when your bathroom starts to look like your bathroom again. Wall and floor tiles are laid according to your design, and the tile adhesive is left to set before grouting.
Tiling is often the longest and most detailed stage. Large-format tiles move faster because there is less cutting, while feature walls, mosaics and intricate patterns take more time. After grouting, the surfaces are sealed. For a standard bathroom this stage runs across several days to a week, depending on the size of the room and the complexity of your tile selection.
Week 4: Fit-Off and Finishing Touches
The final week is where everything comes together. Your plumber returns for the fit-off, installing the toilet, basin, tapware, shower fittings and any freestanding bath. Your electrician fits off the lighting, exhaust fan, power points and heated towel rails. The vanity and custom cabinetry are installed, followed by the shower screen and mirrors.
Once fixtures are in, the room is painted, silicone is applied around the wet edges, and accessories are mounted. The site is given a thorough clean, and your builder walks you through the finished space at handover, checking every detail against the plan. Your new bathroom is now ready to use. For larger bathrooms or projects with bespoke joinery, expect this finishing stage to spread into a fifth or sixth week.
What Can Add Time to Your Bathroom Renovation
Even a well-planned renovation can hit the occasional snag. The most common reasons a bathroom renovation takes longer than expected include:
- Late selections: tiles, tapware or a vanity chosen after the build has started can stall the whole schedule.
- Custom and imported items: bespoke cabinetry, feature tiles and specialty fixtures can carry lead times of several weeks.
- Hidden issues: older Gold Coast homes can reveal water damage, corroded pipework or asbestos sheeting once the walls are opened.
- Mid-project changes: changing your mind on a finish or layout adds both time and cost.
- Curing and drying: waterproofing and adhesive set times cannot be sped up without compromising quality.
Building a small buffer into your timeline turns most of these from a crisis into a minor hiccup. If your build is estimated at five weeks, it is sensible to prepare for six.
Why a Turnkey Renovation Runs to Schedule
Most renovation delays come down to one thing: coordination between separate trades. When a homeowner manages their own designer, cabinetmaker, tiler, plumber and builder, a single scheduling gap can hold up everything behind it.
A turnkey renovation removes that risk. At Hasl Haus, our design team, in-house cabinetry factory and construction crew all work under one roof, so your vanity and joinery are in production while the site is being prepped, and every trade is sequenced by one team from concept to completion. There is no waiting for a subcontractor to become available and no finger-pointing when something slips. It is a genuinely stress-free way to renovate, and a big part of why our projects tend to run to schedule.

Frequently Asked Questions
Can a bathroom be renovated in a week?
Not a full renovation. A purely cosmetic refresh, such as new tapware, a vanity swap and fresh paint with no tiling or plumbing changes, might be done in under a week. Any renovation that involves demolition, waterproofing and tiling needs the full sequence, because waterproofing alone requires 24 to 48 hours to cure before tiling can begin.
How long does waterproofing take to dry before tiling?
Waterproofing membranes generally need 24 to 48 hours to cure, depending on the product, ventilation, humidity and temperature. It is one stage that genuinely cannot be rushed, as tiling over a membrane that has not fully cured risks adhesion failure and future leaks.
Do I need to move out during a bathroom renovation?
If it is your only bathroom, most families arrange alternative facilities during the waterproofing and tiling phases, when the room is unusable. If you have a second bathroom, you can usually stay at home for the whole renovation, though you should expect some noise and dust.
How long does a small bathroom renovation take?
A small bathroom or ensuite still follows the same stages as a larger one, so it usually takes around two to three weeks on site. A small space is not always faster, especially if the layout is changing or problems are uncovered during demolition.
Do I need council approval for a bathroom renovation?
Most like-for-like bathroom renovations that keep the existing layout do not require council approval, but the work still must meet the National Construction Code and Australian Standards and be carried out by licensed trades. Your builder will advise if your specific project needs any approvals.
