Planning a bathroom renovation and not sure where to start? From working out your budget to choosing tiles and understanding waterproofing requirements, there are plenty of things to consider before the work begins.
We’ve put together answers to some of the questions we hear most often from homeowners in Darwin, Palmerston, Humpty Doo and the surrounding Top End areas. If you can’t find the answer you’re looking for, get in touch with the Itile Bathrooms NT team and we’ll be happy to help.
Getting Started
How do I start planning a bathroom renovation?
The best place to start is with a site visit and a quote. We’ll look at your existing bathroom, talk about what you’d like to change and work out what needs to be done.
You don’t need to have every detail decided before getting a quote. Once we understand what you’re looking for, we can discuss the layout, materials, fixtures and other options that may suit your bathroom.
You’ll then receive a written scope of work and quote before the renovation begins.
How far in advance should I book a bathroom renovation?
This depends on the time of year and the renovator’s availability, but it’s a good idea to book several weeks ahead if you have a particular timeframe in mind.
The lead-up to Darwin’s wet season can be a particularly busy period, so booking early gives you more flexibility when choosing a start date.
Do I need a bathroom design ready before getting a quote?
No. You can come to us with a complete design, but you don’t have to.
Some homeowners have a clear idea of what they want, while others might simply have a photo they like or a few ideas for colours and finishes. We can help you work through your options as part of the quoting process.
Bathroom Renovation Costs
How Much Does a Bathroom Renovation Cost in Darwin?
Based on the scope of the renovation, a full bathroom renovation can typically cost between $18,000 and $30,000, with a typical project starting from around $22,000 including GST.
The final price will depend on factors such as the size of the bathroom, demolition requirements, plumbing changes, fixtures, tiles, finishes and any unexpected issues found during the renovation.

Do I need to pay a deposit?
Yes. A deposit secures your renovation booking and helps cover initial material orders.
The remaining balance is paid in stages as the work progresses. The exact payment terms will be included in your written quote before you commit to the project.
Can unexpected costs come up during a renovation?
They can, particularly when renovating an older bathroom.
Once the existing tiles, fittings and other materials are removed, problems such as timber damage, rot or old waterproofing may become visible. If additional work is needed, we’ll explain what’s involved and discuss the extra cost with you before proceeding.
Bathroom Renovation Process & Timeline
How long does a bathroom renovation usually take?
A full bathroom renovation typically takes around 3–4 weeks from demolition to completion.
A smaller ensuite may take around 2–3 weeks, while a larger renovation with custom joinery or more extensive work can take 4–6 weeks.
The exact timeframe depends on the scope of the project and the materials being used. Proper drying and curing time for waterproofing is also allowed for in the schedule.
Can I use my bathroom while it’s being renovated?
Generally, no. Once demolition starts, the bathroom will be out of use until the renovation is sufficiently complete.
If it’s your only bathroom, let us know before the project starts. We can discuss practical options, such as arranging temporary access where possible or planning the renovation around access to another bathroom.
What happens during a bathroom renovation?
Every project is a little different, but the process generally involves:
- Site visit and quote
- Planning and material selection
- Demolition and removal
- Plumbing and electrical work
- Preparation and waterproofing
- Tiling
- Installation of fixtures and fittings
- Final fit-off and clean-up
The exact order can vary depending on the work involved.
Is demolition and waste removal included?
Yes. Demolition and waste removal are included in our full bathroom renovation quotes.
This means you don’t have to organise a separate skip bin or removal service for the renovation.
Bathroom Waterproofing & Permits
Is waterproofing required in a bathroom renovation?
Yes. Waterproofing is an important part of any bathroom renovation and needs to comply with the relevant Australian requirements.
In Australia, bathroom waterproofing is covered by AS 3740. Proper waterproofing helps protect the bathroom and surrounding areas from moisture and water damage.
What waterproofing standard do you use?
Our waterproofing work is carried out to AS 3740, using membrane systems suited to wet-area applications.
Because Darwin has a tropical climate and high humidity, proper preparation and waterproofing are particularly important when renovating a bathroom.
For more information, see our Bathroom Waterproofing Darwin Guide.
Do I need a building permit for a bathroom renovation?
It depends on the type and scope of work.
Simple cosmetic changes may not require a permit, while structural changes or alterations involving plumbing may require additional approvals. The requirements can vary depending on the project.
Where approvals are required as part of a full renovation, we can help with the process.
Tiles, Fixtures & Design
What tiles are suitable for bathrooms in Darwin?
Porcelain tiles are often a practical option for bathrooms because they are less porous than ceramic tiles.
Larger-format tiles can also be worth considering because they have fewer grout lines, which can make cleaning and ongoing maintenance easier.
The best tile for your bathroom will ultimately depend on the space, your preferred style and how the bathroom will be used.
Can I supply my own tiles or bathroom fixtures?
Yes. You’re welcome to supply your own tiles, tapware or fixtures.
We’ll check that the products are suitable for the installation and discuss any requirements that may affect the renovation schedule or quote.
Can you help me choose tiles and fixtures?
Yes. You don’t need to have everything chosen before contacting us.
We can discuss different tile, fixture and layout options during the quoting process and help you choose products that suit your bathroom and the overall look you’re after.
Choosing a Bathroom Renovator
What’s the difference between a tiler and a bathroom renovator?
A tiler generally specialises in tiling and waterproofing, while a bathroom renovator coordinates the wider renovation.
A complete bathroom renovation can involve demolition, plumbing, electrical work, carpentry, waterproofing and tiling. Having these trades coordinated as part of one project can make the renovation much easier for the homeowner.
Itile Bathrooms NT can manage the different stages of a full bathroom renovation, so you don’t have to organise each trade separately.
Are you licensed and insured?
Our tiling work is carried out under a Certificate III qualification, while plumbing and electrical work is completed by appropriately licensed NT tradespeople.
This ensures the relevant work is carried out by qualified professionals.
Do you offer a workmanship warranty?
Yes. Our renovations are backed by a workmanship warranty.
The specific warranty terms for your project will be provided with your quote so you can review them before proceeding.
What areas do you service?
We service Darwin, Palmerston, Humpty Doo, Litchfield, Nightcliff, Larrakeyah and surrounding Top End suburbs.
If you’re unsure whether your property is within our service area, get in touch and we’ll let you know.
