Bathroom Renovation Cost Guide: Melbourne 2026/2027

A bathroom renovation starts with the room you want to live with: a shower that feels generous, storage that works and finishes you enjoy every morning. The budget needs to cover everything behind that result, including work you will never see once the tiles are in place.

This bathroom renovation cost guide helps Melbourne homeowners plan for 2026/2027, understand a published cost benchmark and ask better questions before accepting a quote.

How much does a bathroom renovation cost in Melbourne?

There is no single price that suits every bathroom. A straightforward update to a sound room is a different project from rebuilding a leaking shower, moving drainage or changing the walls around an ensuite.

Start by describing the work, then attach a budget to that scope. Comparing a cosmetic refresh with a complete strip-out simply because both are called a “bathroom renovation” can lead to an unrealistic expectation.

Explore how your bathroom size, scope and finish selections affect an indicative budget using the same calculator available on our bathroom renovation page. Review the inclusions and exclusions alongside your result. An estimate is a planning guide, with final pricing subject to assessment and a written quotation.

What should your bathroom budget include?

Use the checklist below to review the quotation. Some items will already be included, so do not add them again without checking. Where a line is excluded, record who will arrange it and what it may cost.

1. Planning and assessment: Measured layout, design decisions, any required documentation, consultant advice and approvals.
2. Protection and removal: Access through the home, protection of adjoining rooms, removal of existing fittings and finishes, rubbish handling and disposal.
3. Preparation and repairs: Condition of the floor and walls, substrate preparation and any identified damage that needs to be addressed.
4. Services and wet-area work: Plumbing, electrical work, ventilation, waterproofing and the details needed for the proposed shower and floor finishes.
5. Fixtures and finishes: Tiles, vanity, benchtop, basin, taps, toilet, bath if included, shower screen, mirror, lights and accessories.
6. Completion and practical costs: Painting, sealing, cleaning, relevant handover documents and any temporary arrangements while the bathroom is unavailable.

What makes one bathroom more expensive than another?

Changing the plumbing layout

Moving a toilet, shower or vanity can mean more than relocating the visible fixture. The route and accessibility of pipes, the floor construction and the new layout all need to be considered.

Keeping positions may simplify the scope, but it is not always the best choice. If the current arrangement is awkward, compare the cost and everyday benefit of a better layout before committing.

The condition behind the finishes

Ask what can be assessed before demolition and what remains uncertain. If damage is found, understand how proposed repairs will be documented and priced before deciding how to proceed.

A contingency is money you retain for uncertainty. It does not replace a clear scope, and it does not mean every additional charge is automatically justified.

Tile sizes, joinery and installation details

A tile’s shelf price does not tell you its installed cost. Set-out, cutting, preparation and details such as niches or mitred edges can change the work involved.

Likewise, a custom vanity should be considered as a complete selection: dimensions, internal storage, finish, basin, benchtop, tap position and installation. Choose these together so the components work as a whole.

Access and the rest of the home

An upstairs ensuite or an apartment may need different arrangements from a ground-floor bathroom with easy access. Discuss deliveries, protection, working hours and any owners corporation requirements early.

If you are renovating the only bathroom, agree how the household will manage while it is out of use. Include the cost of any alternative arrangements in your personal budget.

Full renovation or supply your own fittings?

ODA Homes offers premium bathroom renovations with fixtures and fittings supplied as part of the agreed scope, as well as installation work for clients who source their own selections.

The useful comparison is the completed scope and the responsibilities that come with it. Owner-supplied products still need to suit the design, arrive when required and be checked before installation.

A discounted fitting is only a saving if it suits the job. Bring product details to the builder before purchasing, particularly where the installation needs to be planned before walls or floors are closed.

Compare bathroom quotes on the same basis

Give each builder the same brief and selection information. Then read the inclusions and exclusions before comparing the final figure.

• Scope: Does each quote cover the same removal, preparation, installation and completion work?
• Selections: Are products specified, or is an allowance doing most of the work?
• Unknowns: Which assumptions depend on inspection or opening up the existing room?
• Responsibilities: Who handles approvals, specialist work and owner-supplied items?
• Timing: What affects the start date, sequence, access and period without the bathroom?
• Price: Is GST included, how long is the quote valid and how will changes be handled?

Understand allowances before signing

A prime cost item is an allowance for a fixture or fitting that has not been fully selected or priced. A provisional sum allows for work whose cost cannot yet be determined precisely.

Consumer Affairs Victoria’s guidance on payments and contract price changes recommends settling selections where possible. Ask how each remaining allowance will be adjusted, including any applicable margin, and keep records of agreed changes.

A low allowance can make the initial figure look attractive while leaving more to pay later. Compare it with the actual items you want rather than assuming it will cover them.

Where to focus your budget first

Begin with the layout and the work needed to make the room function properly. Then decide which visible features matter most to you.

• Prioritise comfortable movement, useful storage and practical lighting.
• Resolve the shower, drainage and wet-area details before choosing decorative extras.
• Use a coherent selection of finishes rather than adding features without a clear purpose.
• Choose products that suit everyday cleaning and maintenance.
• Finalise major selections before construction to reduce avoidable changes.

If the bathroom forms part of a larger project, discuss the overall sequence. Planning laundry renovations or home renovations and extensions together can help coordinate access and decisions, although any cost saving needs to be confirmed in the quotation.
