Bathroom Renovation Cost Australia 2026

Bathroom Renovation cost is really important If you’re staring down a tired shower screen and wondering what a bathroom renovation actually costs in Australia right now, the honest answer is: it depends enormously on scope. According to the Housing Industry Association’s Kitchens and Bathrooms Report, the national average sits around $26,000, but real projects range anywhere from $8,000 for a cosmetic refresh to $50,000-plus for a full luxury rebuild. This guide breaks down exactly where that money goes, so you can budget with confidence before you get your first quote.

How Much Does a Bathroom Renovation Cost in Australia?

Most Australian homeowners spend between $15,000 and $35,000 on a standard bathroom renovation, with the national average landing around $26,000. That figure assumes a typical 4–7 square metre bathroom in a metropolitan area, a like-for-like layout, and mid-range fixtures. Sydney and inner Melbourne renovations tend to run 15–25% above the national average because of higher labour rates and stricter compliance requirements, while regional projects often come in below it.

Bathroom Renovation Cost by Tier

Rather than one number, it’s more useful to think of bathroom renovation cost in three tiers.

Budget refresh — $8,000 to $18,000. Cosmetic update with the existing layout and plumbing retained. New tiles, vanity, toilet, basin, shower screen and tapware, but no structural or plumbing changes.
Mid-range renovation — $20,000 to $35,000. Where most licensed renovators start pricing. Includes quality fixtures, full waterproofing certification, some layout flexibility and better tiling and cabinetry.
Luxury renovation — $35,000 to $50,000+. Structural changes, premium natural stone or porcelain finishes, freestanding baths, custom cabinetry and higher-end tapware brands.

What Actually Drives the Cost

A handful of factors decide whether your renovation lands at the low or high end of these ranges:

Plumbing. Typically 20–35% of total project cost, and it climbs sharply if you’re relocating the toilet, shower or vanity rather than keeping them in place.
Waterproofing. A non-negotiable line item under Australian Standard AS 3740, usually $2,000–$6,000 depending on bathroom size and location.
Structural changes. Moving or removing walls, changing the footprint, or converting a bath-only room to include a separate shower all add significant cost.
Materials and fittings. Large-format porcelain tiles, freestanding tubs and imported tapware sit well above entry-level laminate vanities and standard ceramic tiles.
Hidden issues. Asbestos in older wet-area sheeting, water damage behind tiles, or non-compliant existing plumbing can add thousands once demolition starts — most experienced renovators recommend a 10–15% contingency on top of your quoted budget.

Small Bathroom Renovation Cost

Smaller doesn’t always mean cheaper. Because waterproofing, plumbing rough-in and electrical work cost roughly the same regardless of floor area, a compact ensuite or powder room can cost nearly as much per square metre as a larger family bathroom. Most small bathroom renovations in Australia land between $8,000 and $28,000 depending on scope.

DIY vs Professional: Where the Savings Really Are

Doing some of the work yourself, demolition, painting, or assembling flat-pack cabinetry, can meaningfully cut your final bill. But plumbing, electrical work and waterproofing are legally required to be completed by licensed trades in every Australian state, and in NSW any renovation valued over $5,000 requires a licensed builder to manage the job. Cutting corners here doesn’t just risk your safety, it can void your home insurance. Our full breakdown of what you can and can’t legally DIY covers exactly where the line sits.

How Long a Bathroom Renovation Takes

Budget-wise, timeline and cost are closely linked, delays cost money. A standard renovation takes 2–4 weeks on site once construction starts, or 4–10 weeks from first design conversation to move-back-in once you factor in planning, approvals and material lead times. See our full bathroom renovation timeline guide for a week-by-week breakdown.

Ways to Save Without Cutting Corners

Keep the existing plumbing layout — moving the toilet or shower is one of the single biggest cost blowouts.
Choose a wall-hung vanity and large-format tiles to reduce labour time and grout lines.
Get at least three itemised quotes and confirm what’s included (waterproofing certification, disposal, tiling adhesive grade).
Order tiles, tapware and vanities early — custom or imported items can take 6–8 weeks to arrive and hold up trades if ordered late.
Handle non-structural demolition, painting and styling yourself where your state’s regulations allow it.

Frequently Asked Questions

How much does an average bathroom renovation cost in Australia?

The national average is around $26,000, with most projects falling between $15,000 and $35,000 depending on size, finishes and whether the layout changes.

Is $10,000 enough for a bathroom renovation?

It can be, if you keep the existing layout and plumbing positions and stick to cosmetic updates: new tapware, paint, a refreshed vanity and re-tiling. Anything involving moving plumbing or structural work will push past this budget quickly.

Do I need council approval for a bathroom renovation?

Most standard bathroom renovations that don’t alter the structure or footprint don’t need council approval. If you’re moving walls, changing the layout significantly, or renovating in a strata apartment, check with your local council or body corporate before booking trades.
