Here’s a fun party trick. Ask three people in Wollongong what they paid for their bathroom and you’ll get three wildly different numbers. One says $12,000. Another swears it was $35,000. The third just sighs and changes the subject.
So who’s lying? Honestly, nobody. Bathroom costs swing a lot, and the reasons are pretty simple once you see them laid out.
I’m going to walk you through the bathroom renovation cost Wollongong homeowners can realistically expect in 2026. No fluff, no mystery pricing. Grab a cuppa, because this is the stuff I wish more people knew before they started ringing around for quotes
The Short Answer (For People Who Skim)
Most bathroom renovations in Wollongong land somewhere between $10,800 and $37,800. A mid-range, full renovation with the same layout typically sits around $29,150.
That’s a big window, I know. Local cost guides also show prices have crept up about 4% over the past year, so the numbers you saw on a forum in 2023 are out of date.
Here’s the quick view:
| Type of job | Typical cost in Wollongong (2026) |
| Light refresh (vanity, toilet, tapware, screen only) | $6,000 – $11,000 |
| Small or basic full bathroom | $10,800 – $21,600 |
| Mid-range full bathroom | $21,600 – $37,800 (around $29,150 typical) |
| Premium bathroom | $37,800 – $59,400 |
| Ensuite renovation | $15,000 – $26,000 |
These are guide figures pulled from 2026 Australian cost surveys, and they include GST. Your own quote will depend on your home, your layout and your taste.
What Does “Full Renovation” Actually Mean?
This trips people up. When a builder says “full renovation”, they usually mean a complete strip-out and rebuild inside the existing footprint. That covers:
- Demolition and rubbish removal
- New plumbing rough-in
- Waterproofing
- Tiling on the floor and walls
- Vanity, toilet, shower screen and fixtures
- Electrical work
- Painting and making good
Swapping a vanity and a toilet is not a full renovation. It’s a refresh. And a refresh is a lovely, cheaper option, but the moment the tiles come off, the waterproofing has to be redone, and you’ve crossed into full-renovation territory. Think of it like pulling one thread on a jumper.
Where Does the Money Actually Go?
I always tell people to stop staring at the total and look at the pieces. A bathroom is basically three buckets: labour, the hidden stuff behind the walls, and the pretty stuff you can see.
Labour is the biggest slice. In Wollongong it’s roughly 35–40% of the total. You’re paying plumbers, a tiler, a waterproofer, an electrician and a builder to run it all. Illawarra trade rates sit a little under Sydney, but the gap has narrowed because many local trades also work the southern Sydney market.
Waterproofing is small money but huge stakes. Expect about $1,075 to $3,775 depending on size and how many wet areas you have. It’s only a sliver of the budget, yet it causes most bathroom failures. A failed membrane means water in the wall, rotten framing and, yep, a second full renovation. Never skimp here.
Tiling typically runs $2,150 to $6,500 for the floor and walls. Big format porcelain, mosaics and tricky patterns push you toward the top.
Fixtures and fittings are where your personality shows up, and also where budgets quietly blow out. Which brings me to the next bit.
Prime Cost Items: The Sneaky Part of Your Quote
Ever received a quote that looked amazing, then felt the price creep up later? Chances are, it was down to prime cost items.
A prime cost (PC) allowance is a set amount the builder includes for things like tiles, tapware, the vanity and the shower screen. If you choose something fancier than the allowance covers, you pay the difference.
Here’s the catch. One quote might allow $800 for a vanity, another $2,500. Same bathroom, very different totals, and the “cheaper” quote just hasn’t been honest about the finishes.
So when you compare quotes, ask each builder for their PC allowances in writing. That’s the only way to compare apples with apples.
Bathroom Renovation Cost by Size and Type
Small bathrooms
A small bathroom renovation in Wollongong generally costs $10,800 to $21,600. Think of the 4–6 square metre rooms you find in older cottages around Mount Saint Thomas or a unit in Fairy Meadow.
Small does not mean cheap, though. Tiny rooms are fiddly, trades get in each other’s way, and the fixed costs (waterproofing, plumbing, a toilet) don’t shrink just because the room does. A tip I love: in most small bathrooms, a good walk-in shower beats a bath every time. You get more space and fewer headaches.
Ensuites
An ensuite usually costs $15,000 to $26,000, which is around 20–30% less than a comparable main bathroom. It’s not half the price, though, and people are often surprised by that. The same trades turn up, the same waterproofing is needed and the same plumbing runs.
Ensuites do come with one extra thing worth planning: they share a wall with a bedroom. Acoustic batts in that wall cost very little during the build and are almost impossible to add later. Your partner’s early-morning shower will thank you.
Mid-range vs premium
Mid-range is where most Wollongong homeowners end up, around $21,600 to $37,800. You get decent tiles, quality tapware, a nice vanity and a frameless screen. Go premium and you’re looking at $37,800 to $59,400, thanks to stone, custom joinery, underfloor heating or a freestanding bath.
| Budget tier | What you usually get |
| Refresh | New vanity, toilet, tapware and screen. Tiles stay. |
| Basic full reno | Standard tiles, stock vanity, basic fixtures |
| Mid-range | Quality tiles, better tapware, framed or frameless screen |
| Premium | Large format or stone tiles, custom vanity, heated floors, feature bath |
What Pushes Your Bathroom Renovation Cost Up?
Let me save you some grief. These are the usual culprits.
- Moving things around. Shifting a toilet or shower to a new spot means new plumbing and drainage. Keeping the layout the same is the single easiest way to hold costs down.
- Older homes. A 1980s bathroom can cost an extra $1,500 to $4,000 once you find outdated plumbing or work that no longer meets current rules. Behind the tiles is a lottery, and not the fun kind.
- Fancy tiles. Large format, patterned or natural stone tiles cost more to buy and more to lay.
- Structural changes. Removing a wall or changing the floor structure adds up fast.
- Wet floor surprises. Rotten framing from old leaks is common in older homes.
That’s why a decent quote includes a contingency, usually around 10%, especially on an older house. If a builder says nothing will go wrong behind the walls, I’d be a little nervous.
Do You Need Council Approval in Wollongong?
Often, no. A like-for-like renovation that keeps the same layout usually doesn’t need it. But creating a brand new ensuite, moving drainage or changing the structure is a different story, and you should check with Wollongong City Council early so it doesn’t wreck your timeline.
Your builder should also be happy to tell you which approvals apply. A good one raises it before you ask.
How Long Does a Bathroom Renovation Take?
Honest answer: it depends on who you ask. Some sources say a straightforward full renovation takes two to four weeks on site, while others quote three to six weeks from demolition to completion. Both can be right. The difference is usually waiting time, like waterproofing curing, tile delivery or a trade running late.
A sensible plan is to allow about 3 to 6 weeks and hope for less. And if you’ve only got one bathroom, line up a plan B. Neighbours with a spare shower are worth their weight in gold.
How to Save Money Without Cutting Corners
I’m all for saving, but there’s smart and there’s silly. Here’s where I’d look.
- Keep the layout. This is the biggest saver, by far.
- Spend where it counts. Waterproofing and plumbing are not the places to be thrifty.
- Pick standard tile sizes. They’re cheaper to buy and quicker to lay.
- Choose one feature. A statement tile wall or a beautiful vanity, not six things at once.
- Order fixtures early. Delays in delivery stall the whole job.
- Get your scope in writing. The clearer the brief, the fewer variations later.
And one hard no: don’t pick a quote just because it’s the lowest. Three quotes on the same Wollongong bathroom can differ by thousands, and the cheapest one often leaves out things the others included.
How to Compare Bathroom Renovation Quotes
Give every builder the same written scope. Then check that each quote includes:
- The scope and layout
- Itemised demolition and disposal
- Plumbing rough-in
- Itemised waterproofing that meets the Australian Standard (AS 3740)
- Tiling with a stated tile allowance
- Each fixture with its PC allowance
- Electrical work
- Making good and painting
- A contingency
- A payment schedule linked to stages, not a huge upfront deposit
Getting three quotes is a solid rule of thumb. More than that and you’ll just confuse yourself.
A Quick Word on Value
Will a new bathroom add value to your home? Usually yes, particularly if the existing one is dated, but I wouldn’t treat it as a money printing machine. Do it because you want to enjoy the room. Think of any resale bump as a bonus, like finding a twenty in an old jacket.
