You ask three builders to quote your bathroom. One says $19,000. The next says $32,000. The third comes in at $44,000. Same room, very different numbers. So which one is telling the truth?
The honest answer is that they probably all are. They are just quoting different jobs, even when the bathroom is the same. This guide breaks down what a bathroom renovation really costs around Campbelltown, Camden, and the wider Macarthur region in 2026, and why those quotes can land so far apart.
The short answer
For a full bathroom renovation in Sydney in 2026, most homeowners spend somewhere between $25,000 and $35,000 when the work is done properly by licensed trades. The Housing Industry Association puts the national average at around $26,000, and Sydney tends to run 20% to 40% higher than that. Higher labour rates, stricter waterproofing rules, and the cost of working in older homes all push the number up here.
That is the middle of the road. The full picture sits across a few clear price levels, and where you land depends on what you actually want done.
What you get at each price level
Budget refresh: roughly $8,000 to $15,000
This is a cosmetic update, not a full renovation. Think new tapware, a new vanity, fresh paint, a new light, and maybe a new toilet. The wall and floor tiles usually stay. If your bathroom is sound underneath and you just want it to feel newer, this is a fair spend. You often do not need a full renovation crew for work this light.
Standard renovation: roughly $17,000 to $30,000
This is where most people start when they want the room done properly. It includes a full strip-out, new waterproofing, new tiles on the walls and floor, a new vanity, new tapware, and a new shower. The layout and plumbing stay where they are, which keeps the cost down. For a lot of Macarthur families, this tier delivers a bathroom that feels brand new.
Mid-range renovation: roughly $30,000 to $45,000
Everything in the standard tier, plus better materials and a few upgrades. Larger tiles, a frameless shower screen, a custom or semi-custom vanity, nicer tapware, and small layout changes. This suits homeowners who want a finish that looks designed rather than off the shelf.
High-end and luxury: $50,000 and up
Premium materials, custom joinery, a freestanding bath, heated floors, and structural changes like moving walls or relocating plumbing. This is dream bathroom territory, and the cost climbs fast once you start moving pipes and pouring new floors.
A quick word on layout. The single biggest lever on price is whether you keep your plumbing where it is. Move the toilet, shower, or vanity to a new spot, and you add plumbing, waterproofing, and tiling work that can lift the bill by thousands. Keep the layout, and you save a lot.
Why two quotes for the same bathroom look so different
When quotes are thousands of dollars apart, the gap almost always comes down to what is included. Some quotes cover tiles, some leave them for you to supply. Some include waterproofing certificates and licensed plumbing, some quietly skip them. A cheap quote can look great on paper and then grow once the work starts and the extras appear.
This is one of the most common traps in renovating, so it is worth reading up on the mistakes that derail bathroom projects before you sign anything. A clear, itemised quote that lists what is in and what is out is the best way to compare builders fairly.
The other big factor is who does the work. Licensed trades cost more than cash-job operators, and for good reason. In NSW, plumbing, waterproofing, and electrical work must be done under the correct licence. That protects you if something goes wrong and keeps your home compliant. A quote that comes in far below the rest sometimes reflects unlicensed work, or corners cut on the parts you cannot see.
The hidden costs that catch people out
The figures above assume a straightforward job. The surprises usually show up after demolition, once the old bathroom comes out and the builder can see what is behind the walls and under the floor.
Three things tend to add cost in older Macarthur homes.
Waterproofing and compliance. Proper waterproofing to Australian Standards is not optional, and it adds around $1,500 to $3,000. This is one place you should never cut corners, because a failed membrane means water damage and a second renovation down the track.
A damaged subfloor. If the old bathroom leaked for years, the timber or sheeting underneath may need replacing. You cannot see this until the tiles come up.
Asbestos. Homes built before 2000 can contain asbestos in wall sheeting, vinyl floor tiles, and other materials. If it turns up mid-job, it has to be removed safely and legally before work continues. The good news is that Final Finish handles asbestos removal in-house, so an asbestos find does not mean stopping the job and bringing in a separate company. That keeps your timeline and budget under control.
This is exactly why a contingency matters. Set aside an extra 10% to 20% on top of your quote for the things nobody can see until the work begins. If you do not use it, that money stays in your pocket. If you do, you are covered.
What this looks like around Campbelltown and Camden
The Macarthur region has a lot of brick homes built between the mid 1980s and the early 2000s. Many are now hitting their first major renovation. The bathrooms in these homes were solid for their time, but cream tiles, gold tapware, and leaky shower screens have had their day.
These homes usually suit a standard or mid-range renovation, because the layouts are practical and the bones are good. The main thing to watch is age-related surprises like the ones above. Older Campbelltown, Minto, and Ingleburn homes from the 1970s and 80s carry a higher chance of asbestos, so testing before you start is a smart move.
If you want a clear, itemised price for your own bathroom, the best step is a proper on-site quote rather than a phone estimate. Every bathroom is different, and a builder who walks the room can give you a real number instead of a guess.
