Around here, “small bathroom” usually means one thing: the single main bathroom in a 1960s–90s brick or fibro home, somewhere between 1.8m x 2.4m and 2.5m x 3m, servicing an entire family. No ensuite. No second bathroom to fall back on. Just the one room that everyone in the house has strong feelings about.
We’ll be straight with you — small doesn’t mean cheap, and it doesn’t mean limited. It means every square centimetre has to work harder, and every decision matters more than it would in a big project home ensuite with room to spare. We’ve renovated enough of these to know exactly where the wins are, and we’ll get into that shortly.

One thing worth knowing if you’re in one of the older fibro or brick homes around here: coastal salt air isn’t kind to tapware and fittings over time, and a lot of the original waterproofing in 1970s Illawarra homes simply wasn’t up to today’s standard when it went in. We budget for the possibility of finding tired subfloor timber or old membrane failure once the tiles come off — it’s common enough around here that it shouldn’t be a shock, and it definitely shouldn’t be a surprise invoice.
How can I renovate my bathroom on a budget? Our honest advice, from having done a lot of these:
New tapware and shower fittings, a vanity or toilet swap, retiling just the shower recess, an upgraded exhaust fan and lighting, and a fresh coat of paint or waterproof panelling on walls that don’t need full tiling. None of it is glamorous on its own, but stacked together it makes a real difference to how the room feels day to day.

Here’s the honest truth about the Pinterest board: the freestanding bath in the 4m x 5m ensuite isn’t happening in a 1.8m x 2.4m bathroom, and no reputable renovator should tell you it will. But you’d be surprised how much of that “look” is achievable once someone who does this for a living walks the tape measure over your actual room.

We’ll talk through what’s actually current and practical for your space at the consultation — trends move fast, and not all of them suit a 1970s Illawarra brick veneer.
A few things we’d tell a mate over a beer, not just a customer over a quote:

A typical small bathroom renovation runs 3–5 weeks, start to finish:
We’ll talk you through exactly what you can and can’t use during each stage before you sign anything — because we know what it’s like running a household of four off one bathroom for a month, and we plan around that reality, not around ours.

Every photo we show is from a bathroom we’ve actually renovated across Wollongong and the Illawarra — Figtree, Keiraville, Corrimal, Dapto, Bulli and Thirroul among them.

Walk into most bathrooms in Figtree, Keiraville, Fairy Meadow or Thirroul and you’re stepping into a time capsule — pink or beige tiles, a shower rose with the pressure of a light drizzle, grout gone from white to grey. A lot of those original bathrooms have never been touched since the house was built.
We see the same story on repeat: the kitchen got done, maybe the floors got polished, but the bathroom keeps getting pushed down the list — it feels like the scary room nobody can quote honestly, and you’re pretty sure whatever’s behind that shower wall isn’t good news.
That’s exactly the job we do, every week, across the Illawarra. Small bathrooms, original layouts, tight budgets, real answers. Done properly. On time. No surprises.
In our experience, no — not a genuine renovation, and we’d rather tell you that upfront than let you find out halfway through a build. $5,000 gets you cosmetic changes: new tapware, a new toilet, maybe a vanity, some paint. The second tiling and waterproofing membrane are involved, you’re into proper trade labour and compliance requirements, and that pushes you past $8,000 pretty quickly. Anyone quoting a full reno at $5,000 is either leaving something out or planning to leave something out.
Yes — this is realistic at the budget refresh end, particularly if the layout and shower base are staying put and no plumbing is being relocated. We do these regularly for people who just want the bathroom to stop embarrassing them without a full gut job.
New floor and wall tiles in the wet area, fresh waterproofing, a new vanity and toilet, updated tapware and shower fittings, a coat of paint. Same footprint, same layout — just no longer stuck in 1987.
Waterproofing and tiling, hands down, every time. Waterproofing is slow, meticulous work that has to meet Australian Standard (AS 3740) — and it’s the one part of the job you genuinely cannot rush or skip corners on. Get it wrong and you’re not saving money, you’re just delaying a much bigger bill three years from now when it fails and takes the subfloor with it. We’ve been called in to fix more than one “bargain” reno that turned into exactly that.
As a rough guide, supply and labour for bathroom tiling generally runs $80–$150 per m², depending on tile size, material and how fiddly the layout is. Big feature tiles and mosaics cost more to lay than a straightforward subway tile — more cuts, more time, more skill.
For a small bathroom, waterproofing plus tiling combined usually lands somewhere in the $5,000–$9,000 range as part of a full renovation. It’s the single biggest line item on the quote, and it’s worth every dollar when it’s done right.
Done properly, to Australian Standard, waterproofing is meant to last the life of the building — generally quoted at 10+ years minimum, often much longer. When it fails early, it’s almost always because it was installed poorly the first time, not because it simply wore out. That’s the pattern we see across a lot of the 30–50 year old bathrooms we get called into around here.
Adding a brand-new bathroom — as opposed to renovating an existing one — can require council approval or a Complying Development Certificate under NSW planning rules, particularly if it involves new plumbing connections or changes to the building’s footprint. A like-for-like renovation of an existing bathroom generally doesn’t need a Development Application, but the plumbing and electrical work always has to be done by licensed trades regardless. Worth checking early with your council or your renovator rather than assuming either way — we’ll confirm exactly where your project sits before anything is booked in.
In Wollongong, a full small bathroom renovation typically costs between $16,000 and $25,000, with budget refreshes starting around $8,000 and premium builds reaching $35,000+.
Under 4m², costs generally sit at the lower end — often $14,000–$20,000 for a full renovation, since less material and labour is involved overall.
No forms that trigger three days of sales calls, no “it depends” without a number attached. Just a real conversation, at your place, about your bathroom, your budget, and what’s genuinely possible.
We’ve been doing this up and down the Illawarra long enough to know the difference between what a bathroom needs and what it doesn’t — and we’ll always tell you which is which. Done properly. On time. No surprises.
