What's The Damage, an independent cost guide, puts bathroom renovations at $10,000 to $20,000 (basic), $20,000 to $35,000 (mid-range) and $35,000 to $55,000 (premium) nationally (October 2026). Your real cost depends on the job, and the way to know is a quote.
Brigs Plumbing does bathroom renovations for homes across Brisbane and the Redlands, so below we explain what separates the three tiers, which parts of the job are plumbing, and why a quote is the reliable way to price your bathroom.
What makes a bathroom renovation cost more?
What's The Damage lists these as the things that change the price of a bathroom renovation. They are worth settling before you ask for a quote:
- Bathroom size. A bigger room means more floor, more wall and more fittings to supply and install.
- Fixture quality. Budget fittings sit in the basic tier, quality fixtures in the mid-range tier and premium fixtures in the premium tier.
- Moving the toilet or shower. A new toilet or shower position means new drain positions. This is the plumbing part of the job.
- Structural changes. Altering the room itself, rather than working within the existing walls and layout, changes the scope of the work.
- Redoing waterproofing. What's The Damage notes that waterproofing is mandatory, and whether it has to be redone is one of the things that changes the price.
Keeping the existing layout is what defines the basic tier in the table above. Once the toilet or shower moves, the drains have to move with it, so it is worth deciding early whether the new layout is worth that extra plumbing work.
How much contingency should I allow?
What's The Damage advises adding a contingency of 15 to 20 percent on top of your renovation budget.
Set the contingency aside separately from the quote, and treat it as money you hope not to spend rather than part of the plan.
Want a firm price for your job?
We look at the job and quote before any work starts, so you know the cost up front.
Can I renovate a bathroom on a tight budget?
$10,000 is the bottom of What's The Damage's national basic range (October 2026), so it is the starting point of that tier rather than a guarantee. The basic tier means budget fittings and the existing layout. Not moving the toilet or shower avoids new drain positions, which is what helps keep a job in that tier. A quote for your actual bathroom is how you know whether your budget is enough.
Why do bathroom renovation prices vary so much?
The national ranges are wide because bathrooms are different. Two homes in the same suburb can land in different tiers depending on the room's size, the fixtures chosen, whether the toilet or shower moves and whether waterproofing has to be redone. A published range cannot see any of that, and neither can an average.
That is why the real cost depends on the job. A quote based on your actual bathroom turns the national tiers into a figure that applies to you. Brigs Plumbing quotes every job before work starts, so you know where you stand before anything begins.
Frequently asked questions
Is there an average cost for a bathroom renovation?
An average hides the differences between tiers, so this page does not give one. What's The Damage splits renovations into basic, mid-range and premium tiers nationally, at $10,000 to $20,000 (basic), $20,000 to $35,000 (mid-range) and $35,000 to $55,000 (premium) as at October 2026. Where your bathroom sits depends on its size, fixtures, layout and waterproofing, which is why a quote is the reliable way to know.
Are these Brisbane prices?
No. They are national figures from What's The Damage, an independent cost guide, as at October 2026. No Brisbane-specific published range is used, and none of the figures are Brigs Plumbing's prices.
Does moving the toilet or shower change the cost?
Yes. What's The Damage lists moving the toilet or shower, which means new drain positions, as one of the things that changes the price. Keeping the existing layout is part of what defines the basic tier.
