Most Sydney bathroom renovations cost between $15,000 and $45,000. Here is an honest breakdown of the price ranges, what drives the cost up, and how to get a quote you can trust.
TL;DR: A bathroom renovation in Sydney typically costs $15,000–$45,000 depending on size, scope and finishes. A cosmetic refresh starts around $8,000; a full gut with stone and custom joinery runs to $45,000 and beyond. Scope and waterproofing drive the cost.
The short answer on bathroom renovation cost in Sydney: most projects land between $15,000 and $45,000, depending on the size of the room, how much you're changing, and the finishes you choose. A like-for-like refresh sits at the bottom of that range. A full gut with stone, quality fixtures and custom joinery sits at the top. I'm a licensed contractor based in Liverpool, and over the past twelve years I've renovated bathrooms right across Sydney — inner-city apartments, eastern suburbs terraces and family homes out west. This guide lays out what you should expect to pay in 2025, what pushes the price up, and how to read a quote so you know exactly what you're getting. The same room can come back at wildly different numbers depending on the waterproofing, the tile, the fixtures and how many trades are involved — and most people have no easy way to tell whether a quote is fair or just cheap. That's what the rest of this guide is for. No padding, no sales spin — just real numbers and the reasoning behind them.
The biggest single driver is whether you're doing a cosmetic refresh or a full gut. A refresh keeps the layout, the plumbing and the waterproofing in place and updates what you can see. A full gut strips the room back to the studs and slab, which means new waterproofing, new services and a longer trade schedule. The gap between those two approaches can easily be $20,000 on the same sized room. Room size matters next. A small ensuite has less floor and wall area to tile, fewer fixtures and less labour than a large family bathroom. Tiling is priced by the square metre, so a bigger room costs more before you've chosen a single tap. Waterproofing is not optional. Under the NSW building code and AS 3740, wet areas must be waterproofed to standard by a licensed applicator, and the work has to be certified. It's one of the most important parts of the job and one of the most common places cheap quotes cut corners. Then there's the trades. A proper bathroom needs a plumber, a tiler and an electrician at minimum, and they have to be scheduled in the right order. The more trades involved and the tighter the sequencing, the more the coordination costs. Tile selection swings the budget hard too — a basic ceramic tile is a fraction of a large-format porcelain slab or natural stone. Finally, custom vanity and cabinetry costs more than an off-the-shelf unit, but it's made to fit the room exactly and lasts far longer in a wet environment.

The mid-range bracket is a full strip-out and rebuild in the same layout: new waterproofing, new tiles, a new shower, vanity and toilet, done properly. The full renovation bracket adds quality fixtures, custom joinery and minor layout changes, and is where most owner-occupiers land. Premium projects involve large bathrooms, stone surfaces, freestanding baths and full custom work. The number cheap quotes quietly leave out is almost always waterproofing certification, proper tile preparation, and rubbish removal — so a $9,000 quote and a $16,000 quote for the "same" job are often two very different scopes. You can see the range of work we do on our <a href="/bathrooms">bathroom renovations</a> page.
A quote you can actually compare should spell out every line of the job, not bundle it into one number. At a minimum it should cover: demolition and rubbish removal; waterproofing certified to NSW standards; floor and wall tiling, including the preparation underneath; the shower screen; the toilet suite; tapware and mixers; lighting; an exhaust fan; painting; and the vanity and any custom cabinetry. With every InsideOut quote you get a detailed, itemised scope and a clear material schedule before any work starts — so there are no surprises about cost or finish, and you can change your mind on paper rather than on site. We are a licensed contractor with 12 years of experience, so the number you sign is the number you pay. We also run the whole job as one team. The plumber, tiler, electrician and the joinery all come through us, scheduled in the right order. You're not chasing five different contractors, holding the project together yourself, or copping the gaps when one trade blames another. One point of contact, one quote, one team responsible for the result.
Most blowouts come down to a handful of avoidable things. First, know the difference between a fixed-price quote and a provisional one. A fixed quote commits to a number for a defined scope; a provisional quote uses allowances that can move once selections are made. Provisional isn't a trap — but you need to know which one you're signing so you can budget for the gap. Second, check the contractor's licence. In NSW you can look up any builder on the Fair Trading website and confirm the licence is current and covers the work. It takes two minutes and tells you whether the person quoting is actually licensed to do the job. Third, ask who manages the project day to day. If the answer is vague, that's your warning sign — someone has to own the schedule and the trades. Fourth, understand lead times. Imported tiles, stone and certain fixtures can take weeks to arrive, and ordering late stalls the whole job. We sort selections early and typically turn a standard bathroom around in about three weeks on site once materials are in. Finally, lock the scope before work starts. Scope creep — changing the tile, moving the shower, adding a niche mid-job — is the fastest way to push a budget past its limit. Lock it in on paper, then build it.
In Sydney's market, a well-done bathroom is one of the renovations buyers notice most, and it usually returns a solid share of its cost at sale — particularly in established suburbs where dated bathrooms stand out. A tidy mid-range renovation often delivers the strongest return relative to what you spend. It helps to think in cost per square metre rather than one big number. A small, well-finished bathroom can cost more per square metre than a large one because the fixtures, waterproofing and trades are much the same regardless of floor area. That's normal, not a markup. The real argument for doing it properly is longevity. A cheap job that skips waterproofing prep or uses bottom-end fixtures often needs redoing within a few years — and ripping out a failed bathroom and starting again costs far more than doing it once, correctly. If you're keeping the home, quality pays for itself in the years you don't spend fixing it. If you're selling, a clean, current bathroom helps the sale. If you're also updating the kitchen, our <a href="/blog/kitchen-renovation-cost-sydney">kitchen renovation cost guide</a> walks through the same numbers for that room.

A standard bathroom renovation takes about two to four weeks on site from the start of demolition to completion, and we typically turn ours around in around three weeks once materials have arrived. Full layout changes, structural work or custom finishes add time. Before any trades start, allow roughly four to six weeks for design, sign-off, and ordering tiles and fixtures — imported items in particular can have long lead times, so getting selections locked in early is what keeps the job on schedule.
Most internal bathroom renovations do not need council approval, because you're working within the existing footprint. Approval or certification usually only comes into play if you're moving plumbing significantly, altering a load-bearing wall, changing the building's external footprint, or working on a heritage-listed or strata property where extra rules apply. Waterproofing still has to be done to NSW standards and certified regardless. Your contractor should tell you upfront whether your specific job needs any approvals before work begins, so there are no surprises partway through.
The cheapest genuine renovation is a cosmetic refresh that keeps the layout intact — new tapware, a new vanity, fresh paint and updated fixtures, with the shower, toilet and vanity all staying in their existing positions. That avoids the big costs of relocating plumbing and re-waterproofing the whole floor, which can add $5,000 to $10,000 on their own. It only works if the existing tiles and waterproofing are still sound, though. If the waterproofing has failed, a refresh just hides the problem, and you'll pay for it again later.
