Full Cost Breakdown — Every Trade, Every Line Item
The remodelling of a bathroom in Perth is not a one-time investment but a series of specialised jobs that occur in a sequential order to achieve a final result. From the beginning of demolition to the last polish of mirrors and fittings, each phase demands a different budget. But how much does a bathroom renovation cost in Perth exactly? Let’s look at a proper breakdown of the costs below.
Demolition & Strip-Out
The transformation starts during the demolition. It includes the process of dismantling the old tiles, fixtures, cabinetry and sometimes even some wall or floor surface to support the new installation.
- Typical cost: $1,000 – $3,000
The ultimate cost will be determined by accessibility, material and whether disposal of hazardous materials such as asbestos is required. Most renovation contractors usually include waste disposal. But it is always good to clarify in order to avoid extra charges later.
Waterproofing (Legally Required in WA)
One of the most important processes in a bathroom renovation is waterproofing. It helps your house to avoid being ruined by the moisture and should be in accordance with the Australian Standard AS 3740.
- Typical cost: $800 – $1,800
Although this might seem like a hidden cost, you might need expensive structural upkeep in the future due to inadequate waterproofing. Never forget to demand a compliance certificate as an assurance that the work is in line with the requirements of the WA regulations.
Tiling — Walls & Floors
Tiling determines the appearance and the longevity of your bathroom. The bathroom tiling cost includes surface preparation, laying tiles, grouting and sealing.
- Tile supply: $30 – $120 per m²
- Labour: $45 – $120 per m²
In 2026, a good percentage of homeowners in Perth are opting to have large-format porcelain tiles in their homes to ensure a smooth and contemporary appearance with fewer grout lines. These tiles look good and also perform better against Perth’s mineral-rich water.
Plumbing
Plumbing is the keystone of the functionality of your bathroom. The plumbing cost includes the installation of new fixtures, connecting the water supply lines and adherence to the WA plumbing codes.
- Typical cost: $1,500 – $5,000
The average bathroom remodel cost would be exponentially high when you want to relocate important features, such as the toilet, shower, or vanity, because this would mean that you would have to re-lay the pipes and possibly even the drainage systems.
Electrical Work
Electrical services will make sure that your bathroom is safe, well-lit, and well-ventilated. These involve fitting of lighting, power points, exhaust fans and safety switches.
- Typical cost: $800 – $2,500
Given Perth’s climate, proper ventilation is essential to prevent mould and moisture build-up. It can also enhance the longevity of floor or wall tiling. Upgrading or installing a high-quality exhaust system may add $300 – $800, but it is a worthwhile investment.
Fixtures & Fittings
Fixtures and fittings are where functionality meets design. It can range from a bath remodel to installing new tapware. Some homeowners also need a lot of shelves and cabinets in the bathroom. If you are one of them, you must get in touch with experienced Perth carpenters. These decisions may have a huge impact on the appearance and the overall cost of the renovation.
Typical Perth pricing:
- Vanities: $400 – $3,000
- Toilets: $250 – $1,200
- Shower screens: $800 – $2,500
- Freestanding bathtubs: $1,200 – $5,000
- Heated towel rail (installed): $300 – $1,000
- Tapware installation: $150 – $400 each
Painting & Final Finishes
The last phase of bathroom renovation in Perth is the finishing touch. This involves painting, sealing, fixing mirrors and other accessories.
- Painting ceiling and trims: $300 – $800
- Final sealing, mirrors, accessories: $500 – $1,500
These minor details affect the final stability of the bathroom a lot. Go with high-quality paints and sealants to make your renovation look fresh for years.
What Drives Your Bathroom Renovation Cost Up (Or Down) in Perth
Even within the same budget, there are a few factors that affect your ultimate bathroom remodel cost.
Bathroom Size & Type
Surprisingly, the cost to renovate small bathrooms is often higher than that of bigger ones.
- Under 5 m²: $10,000 – $18,000
- 6–8 m²: $18,000 – $30,000
- 10 m²+: $25,000 – $55,000+
Layout Changes
The relocation of plumbing connections costs $800-2500 or more, depending on the complexity.
Tile Choice & Coverage
Premium tiles and full height tiling may cost $80 – $150 per m² installed, increasing both labour and material costs. Looking for the most experienced Perth tilers? Contact our team at Boda Building Group.
Age of Home & Hidden Issues
Older Perth homes may require asbestos removal or plumbing upgrades. Add another 10-15% to your budget for this.
Perth Suburb Location
The cost of renovation of a bathroom also varies based on the location. It is a lot more predictable in the northern suburbs. Renovation costs are the cheapest in the southern suburbs. If you live in the hill areas, be ready to pay more because of limited access and plumbing complexities.
