Factors that affect bathroom renovation timeframes

So, how long does a bathroom renovation take? Unfortunately, every bathroom renovation is different and therefore, will take a different amount of time.


The average time needed to renovate a bathroom is usually anywhere between 2 – 8 weeks.


The time frame is determined by the following factors:


  • The size of your bathroom
  • Whether it is a full or partial renovation
  • Major plumbing and electrical changes
  • How complicated the renovation is
  • The availability of materials
  • Speciality products wanted, such as anything custom built, vanities, showers
  • Structural changes
  • Unforeseeable events, out of the renovator’s control

The phases of a bathroom renovation

There are two overarching phases when it comes to renovating your bathroom.


bulding phase


Phase one is the pre-construction phase. This includes design and planning, permits & approvals, and sourcing materials. The pre-construction phase is estimated to be around one to six weeks depending on the above factors.


Phase two is what we refer to as the building phase. This includes, demolition and preparation, waterproofing and electrical work, modelling and fitment, painting, cleaning and waste removal. This building phase is averagely around three weeks, but could be more or less depending on differing factors.


Pre-construction phase


Design & planning

The planning period is about design, and deciding what style, layout, and features you want for your bathroom. If you are one of those people who get overwhelmed by the design process you won’t have to worry one bit, working with a renovation company will mean this part of the process will be a breeze. 


Professional bathroom builders and renovators can bring their expertise to the mix, as they will have their finger on the pulse when it comes to the current bathroom styles and features you may be wanting.


Permit & approvals (where required)

Depending on your project, you may need a permit. This could be because you live in a

strata-governed building complex, which has their own rules and regulations regarding

changes that can be made to the building. You may also need to apply for a permit from

the council.


Unsure if you need a permit? Consult with your renovating company, who should

be able to help you determine if you need to acquire any of these permits.

Don’t delay when sourcing a permit. Permit approval can usually take around one to four

weeks. It should be done as quickly as possible, as you could become stuck at the mercy

of the council waiting for your approval, slowing down your whole renovation process.

Sourcing materials

Sourcing the materials needed to renovate your bathroom could take up to two weeks,

potentially longer if material shortage issues arise. Ordering the materials is done in

advance of the work to make sure the essential materials are there ready to go at the

worksite on day one.


Building phase

Demolition & preparation

The demolition and preparation phase is when the old bathroom is gutted out and

prepared for the upcoming work. This will include removing unwanted fixtures that will

be replaced such as baths and vanities. If walls are being repositioned or plumbing pipes

are being moved, this will happen then too, while the walls are off.


Waterproofing & electrical work

Along with the movement of plumbing, if necessary, electrical wires can also be moved

or added at this time, while the Gib sheeting on the walls is removed. This would 

happen if a power point is needed in another part of the room, or a heated towel rail is 

being installed.


Waterproofing is one of, if not the most, important aspect of a bathroom renovation. If

your bathroom isn’t waterproof you will quickly incur water damage inside your walls,

and under your flooring. This can create dangerous black mould and rot away the

structural integrity of your build. Therefore, waterproofing needs to be done by a 

qualified professional, to make sure the job is done correctly.


Modelling & fitment

Modelling and fitment of your brand-new sparkly fixtures means you’re past the hard 

part, and nearing the end of your bathroom renovation. Installation of your fittings, 

such as new taps, and your fixtures, showers, baths, and vanities, should be a relatively 

quick process, around one to three days.





Painting is only required if you opt for a bathroom with partially bare walls, as painting is

not needed for a fully tiled bathroom. Good painting practises include one coat primer

and two top coats, for a nice smooth finish.


Cleaning & waste removal

Once everything is installed, dried and cured, a final deep clean will go ahead for your

bathroom. All debris and dust will be cleaned up and taken away, and then a last 

inspection will be carried out to make sure everything looks right and works correctly.


Final Thoughts

Renovating your bathroom can be a big job. How long the renovation will take is dependent on so many different factors, but the outcome is always worth the wait.
