Bathroom Renovation Ideas That Still Look Right in Ten Years

Almost everyone starts a bathroom renovation by collecting tile images. It's the wrong order. Tiles are a finish; the layout is what determines whether the room works every morning for decades to come.

Before you choose a single material, map the three functional zones — wet (shower and bath), wash (vanity and mirror), and WC. A good layout keeps the WC out of the sightline from the door, puts the vanity where natural light hits it, and gives the shower the largest continuous run of wall available. Under the NCC and AS 3740, the shower zone also dictates where waterproofing has to extend up the wall (minimum 1800mm in the shower area, 150mm elsewhere) and how the floor waste is set out, so zoning isn't just aesthetic — it's the basis of your wet-area compliance.

The most valuable layout change in an older Sydney home is removing the wall between a separate toilet and the bathroom. In a 1970s or 80s brick veneer home, that single move typically converts two cramped, useless rooms into one properly proportioned bathroom without touching the external walls or the roof line.

The right idea for your bathroom depends heavily on what you're starting with. Sydney's Hills District and Western Sydney corridor is a mix of three broad building eras, and each one comes with a different set of constraints and opportunities.

1970s–80s brick veneer homes (common through Baulkham Hills, Winston Hills, parts of Blacktown) typically have a separate toilet, a timber joist floor and a bathroom under 6m². The timber floor means we can usually reroute waste and supply pipework without breaking concrete, which opens up wall removal and full reconfiguration relatively cheaply. 1990s–2000s double-brick and slab-on-ground homes (Kellyville, Castle Hill, Quakers Hill) usually already have a combined bathroom and ensuite but with dated 90s fittings — corner spa baths, framed mirrors, beige tile. These respond well to a full strip-and-rebuild without moving walls. Newer estate homes (Marsden Park, Box Hill, The Ponds, built post-2015) often have reasonable layouts already, so the ideas that add the most value are finish-level: tile upgrade, tapware, lighting, and storage, without structural change.

Most Sydney bathrooms are between 4m² and 8m². You can't add floor area without moving walls, but you can change how much of it you see.

The single most effective trick is visible floor. Every square metre of uninterrupted floor the eye can travel across reads as space. That's why a wall-hung vanity and a wall-hung toilet pan make a small room feel dramatically larger than the same room with floor-mounted versions — you're seeing the tile run right to the wall.

Tile is where most of the visible budget goes and where most regret lives. Our rule with clients: let the floor and main walls be quiet, and spend the personality budget on one controlled feature.

Large-format porcelain in a warm off-white, bone or soft greige has been the reliable base for a decade and shows no sign of shifting. Where people want texture, a vertical-stack or herringbone feature behind the vanity or in the shower niche delivers it without committing the whole room.

The finish matters more than the pattern. Matt and honed surfaces hide water spotting and soap film far better than gloss, and a P3 or P4 slip rating (equivalent to an R10 wet-pull rating under AS 4586) on the floor is a legal and practical requirement, not an upsell. Wet areas with a shower step or ramp typically need R11.

Brushed brass and warm gold have dominated Australian bathrooms for several years now. They still look good, but if you want a genuinely neutral choice, brushed nickel and matt black have proven more resistant to changing taste.

Whichever finish you pick, buy the whole room in one range from one brand. Mixed 'brushed gold' from three suppliers will not match — the undertones differ, and it's obvious in daylight.

Practical note for Hills and Hawkesbury properties on tank water or older mains: check your delivered water pressure before specifying tapware. A high-flow rain head needs at least 200kPa to perform properly; on a 150kPa system it's a disappointing shower, and no amount of design fixes it. We test static pressure on-site before finalising the tapware schedule.

Storage is the most common complaint about a finished bathroom, and it's almost always something that could have been designed in for very little money.

A single ceiling downlight in the middle of the room is why most bathrooms look worse in person than in the brochure. It puts your face in shadow at the mirror and flattens every texture you paid for.

Build the lighting in three layers: general ceiling light, task light at the mirror (either a backlit mirror or wall sconces either side at eye height), and a low-level or shower-zone light for night use. Put the layers on separate switches.

Use a warm colour temperature — 3000K to 3500K. 5000K 'daylight' globes make even beautiful stone look clinical.

A bathroom fan sized for the room next door will not clear a steamy shower. Australian Standard AS 1668.2 and the NCC set minimum exhaust rates; for a typical 5-8m² Sydney bathroom you want an exhaust fan rated at 250-300 L/s (litres per second) of free air, ducted to outside air, not into the roof cavity.

Duct run length and bends matter more than the fan's rated capacity. Every 90-degree bend in flexible ducting effectively costs you 1-1.5 metres of straight run in performance. A fan rated at 250 L/s on a straight 2m duct can perform like a 150 L/s fan after three bends and a 6m run — this is the single biggest reason new bathroom fans underperform.

If there's a window, use it as backup ventilation, but don't rely on it as your primary exhaust — condensation happens fastest at night when windows are shut.

Every idea on this page is downstream of the waterproofing membrane. AS 3740-2021 sets the minimum standard: a fully bonded membrane over the shower floor and walls to a minimum of 1800mm, 150mm upturns at all other wet-area walls, and 100mm minimum up the door architrave.

Screed falls are just as critical as the membrane itself. The bathroom floor needs to fall at a minimum ratio of 1:80 toward the floor waste or linear drain, with no ponding areas — we check this with a level and a hose before any tile goes down. A linear waste set into the shower wall, rather than a centre-floor drain, lets us run a true single-direction fall and keeps the visual line of the floor cleaner, which ties directly back into the small-space ideas above.

Get a waterproofing certificate from a licensed applicator on every wet-area job. It's required for home warranty insurance (HBCF) on renovations over $20,000 in NSW, and it's the document that protects you if a leak shows up in the ceiling below in three years' time.

A growing number of our Hills District clients are renovating with the long term in mind, not just the next few years. Building in accessibility now, while walls are open, is dramatically cheaper than retrofitting later.

AS 1428.1 sets out the dimensions for accessible design, and while most residential renovations aren't required to meet full compliance, borrowing the principles pays off. A hobless shower with a 1200mm minimum clear entry width, a fold-down or fixed shower seat, and grab-rail-rated wall blocking (structural noggins behind the sheeting, not just plasterboard anchors) cost very little extra if they're specified before the walls close up.

We're not in the business of refusing work, but part of the job is telling you what we've seen fail.

It's more useful to think in tiers than in a single average cost, because the ideas available to you genuinely change at each level. These are typical Sydney ranges for a standard 4-8m² bathroom, supply and install, in a single-storey home with reasonable access.

The gap between a Pinterest board and a working bathroom is a measured plan, a fixture schedule and a clear, detailed written contract. When we quote, we produce all three — a scaled layout, a line-by-line list of every fixture, tile and fitting with its supplier code, and an itemised quote against it.

That's the document that protects you. If a builder can't tell you exactly which mixer, which base, which membrane and which tile is in the number they've quoted, they haven't priced your bathroom — they've guessed at one. NSW Fair Trading requires a written contract with a fixed scope for any residential building work over $5,000, and Home Building Compensation Fund (HBCF) cover is mandatory once the contract value passes $20,000 — check both are in place before signing anything.
