Ask anyone who's been through a bathroom reno and you'll hear the same story — chaos, stress, and a bill that stings. Tiles ripped off walls, pipes relocated God-knows-where, a final invoice that'd make your eyes water. That's a full structural gut-job — but here's the thing, it's nowhere near the only path to a better bathroom. There's a massive gap between a cosmetic refresh and a full structural reno — get that wrong and you'll torch your budget before week two even starts, rather than walking away with a room that's actually changed.
This article focuses on the first two camps. No moving walls, no relocating drains.
Stand in your bathroom and actually look at it — properly. How are those grout lines looking? What's the silicone around the bath like — is it still sealed? Any cracked tiles? Paint peeling off the ceiling? And the waterproofing — is it still holding? Plenty of people burn through every dollar on cosmetics, then find out too late there were structural problems underneath that should've come first.
A rough 80/20 split works well here — put the bulk of your money into the vanity, tapware, and shower, the things that cop daily use, and spend next to nothing on candles and print frames. Here's the non-negotiable — tapware connections, toilet and basin installs, waterproofing membranes, hardwired electrical: all of it goes to a licensed tradesperson, full stop, as required under plumbing licensing legislation in your area. DIY plumbing or waterproofing is flat-out illegal across every area — no exceptions. Factor that cost in from the very start — don't let it blindside you mid-project.
Few things shift a bathroom's feel as fast as fresh paint and new hardware.
Walls need a moisture-resistant acrylic enamel — semi-gloss or gloss, with at least 40 per cent sheen. Do not skip primer. Standard interior paint has no place in a wet zone — don't even consider it. And don't rush the prep work — that's where most DIY jobs come unstuck.
Hardware is your next move. Pull out the towel rails, toilet roll holders, and robe hooks and replace them all in a single consistent finish — Matt Black is everywhere right now, though Brushed Gold and Brushed Nickel are both having a genuine moment — and the result looks like you spent twice what you actually did.
Sharp surfaces and fittings sorted — now it's time to look at the fixtures your family and guests actually put their hands on every day.
A new showerhead is gloriously simple — swapping a showerhead is generally DIY-legal. When choosing, look for a WELS star rating label. Higher-rated fixtures use less water per minute, which genuinely adds up on your water bill. While you have your plumber in, discuss your exhaust fan. Often, a bathroom that feels damp and mouldy is simply the result of a poorly performing exhaust fan.
Now that tapware and toilet are addressed, it's time to Renovate Your Bathroom at a deeper level by considering the more impactful items in the space.
If you're replacing a vanity, cheap bathroom vanities are available in the most common standard widths of 600 mm, 750 mm, and 900 mm. Always opt for a PVC cabinet over MDF where possible.
Got a vanity that's structurally fine but looks like it belongs in 1994? A painted bathroom vanity can keep material costs low. Thorough prep is non-negotiable with a painted bathroom vanity — clean it down, sand it back, prime it, then finish with a high-traffic enamel. Get it right and you'll completely Renovate Your Bathroom's most prominent fixture.
Regarding baths, resurfacing is worth considering if your existing unit is scratched or tired. However, if your bath is more than 15 years old, replacement is the better option. tub acrylic is lighter than cast iron or steel, holds heat well, and is considerably cheaper. Standard bath lengths are 1500 mm, 1675 mm, and 1700 mm — measure your existing bath before purchasing. Your plumber installing the new bath can also ensure surrounding wall surfaces are water-resistant to at least 150 mm above the vessel rim.
While the plumber's on site, knock over the compliance stuff at the same time — it keeps costs down and saves grief down the track, and you don't have to replace every single thing to feel like the room's had a proper overhaul. Stack a handful of smaller, high-impact changes on top of each other — that's the actual recipe for a budget reno that works.
