A Sydney builder’s honest guide to bathroom renovation timelines and costs in 2026: from 3-week standard renos to strata approvals and what drives the price.
Two questions come up in almost every conversation before a Sydney homeowner commits to a bathroom renovation: how long will I be without a bathroom, and what is this actually going to cost? Both are fair questions, and both deserve a straight answer.
For most Sydney homes, a full bathroom renovation takes 3–4 weeks on site for a standard strip-and-refit in the same footprint. Complex jobs involving plumbing relocation or structural changes run 5–8 weeks. If you are in a strata apartment, add 2–5 months to your planning phase to get Owners Corporation approval before a single tool touches a wall.
On cost, expect to pay $20,000–$35,000 for an entry-level full renovation, $35,000–$65,000 for mid-range, and $65,000–$120,000+ for prestige finishes. Below, we break down exactly what drives those numbers and why timelines in Sydney frequently blow out past initial estimates.
What Affects How Long a Bathroom Renovation Takes
Scope of Work
A cosmetic refresh (new tapware, vanity swap, resurfaced tiles) runs in days to a week or two. A full renovation where everything comes out and goes back in a different layout is an entirely different project. The more trades involved, the more sequencing dependencies, and the more opportunities for delays.
Trades Sequencing
Bathroom renovations are sequential, not parallel. Waterproofing must cure before tiling. Tiling must be complete before fixtures are set. Electrical rough-in must be done before walls are closed. You cannot compress this sequence by throwing more people at it; the physics of curing times and inspection hold points do not change.
Waterproofing Cure Times
Under AS 3740 (the Australian Standard for waterproofing wet areas), membrane cure times must be respected before the next trade commences. In Sydney’s climate this typically means 24–48 hours between coats, and a mandatory inspection before tiling begins. Rushing this stage is how bathrooms fail within a few years.
Material Lead Times
Imported tiles and fixtures are a common cause of delays. European tapware, stone slabs, and custom-ordered vanities can have lead times of 6–12 weeks, sometimes longer. A builder who hasn’t ordered materials before demolition starts is setting you up for a stalled site.
Strata Approvals
For apartment owners, the Owners Corporation (OC) approval process operates entirely outside the builder’s control. Strata committee meetings happen monthly or quarterly. If your application misses a meeting, you wait another cycle. Factor this into your planning horizon, not your construction timeline.
Hidden Issues
Pre-existing waterproofing failures, substrate damage, and deteriorated framing are found after the walls come down, not before. In Sydney’s older building stock, these are common enough to plan for rather than hope to avoid.
Realistic Timeline by Renovation Size
Small Bathroom Refresh (Cosmetic Only, No Layout Change): 1–2 Weeks
No demolition to structure. New tapware, vanity, toilet suite, accessories, and possibly resurfaced or retiled surfaces in the existing footprint. Trade sequencing is minimal. This assumes no hidden defects emerge once work starts.
Standard Full Renovation (Full Strip and Refit, Same Layout): 3–4 Weeks
Everything comes out: tiles, substrate, fixtures, waterproofing. The room is rebuilt from scratch using current standards. This is the most common project type for Sydney homeowners upgrading a 20–30 year old bathroom. It involves waterproofing, plumbing, tiling, electrical, and fit-off trades in sequence.
Complex Renovation (Layout Change, Plumbing Relocation, Structural): 5–8 Weeks
Moving the shower to the opposite wall, relocating waste points, or opening up a structural wall changes the scope significantly. Plumbing relocation may require penetrating concrete slabs, depending on building type. Engineering or council involvement adds further time.
Strata Apartment Renovation (Any Wet Area Work): Add 2–5 Months to Planning
Under the NSW Strata Schemes Management Act 2015, wet area renovations (which include any bathroom work involving waterproofing) require OC approval as a minimum minor renovation. This typically needs a general meeting resolution or committee approval under the strata’s by-laws. In Eastern Suburbs and Bayside apartments, expect to submit a detailed scope of works, waterproofing methodology, and confirmation of licensed trades. Allow 2–5 months from initial application to approved start date, and do not demolish anything until approval is in writing.
Week-by-Week Trades Sequence: Standard 3–4 Week Renovation
This is what a standard full renovation looks like on site. Understanding this sequence explains why you cannot use your bathroom until week 3.
| Week | Stage | What Happens |
| Week 1 | Demolition | Tiles stripped, substrate removed, old fixtures disconnected and removed. Any hidden damage (substrate rot, failed waterproofing, asbestos sheeting) is identified now. Scope adjustments happen here if required. |
| Week 1–2 | Waterproofing | New substrate laid. Waterproofing membrane applied to floor and wet walls to AS 3740. Minimum cure time observed. Mandatory inspection by certifier before tiling proceeds. |
| Week 2 | Plumbing Rough-In | Plumber sets rough-in positions for shower, bath, vanity, toilet. In a same-layout renovation this is straightforward. Any waste or water line adjustments happen now while walls are accessible. |
| Week 2–3 | Tiling | Floor and wall tiles laid. Grout applied and cured. This is typically the most time-consuming stage and is dependent on the complexity of the tile format and layout. Large-format stone or book-matched slabs take longer than standard ceramic. |
| Week 3 | Fixture Installation | Vanity, toilet, shower screen, bath (if applicable) installed. Plumber returns for second fix, connecting tapware, waste fittings, and commissioning water supply. |
| Week 3–4 | Electrical | Exhaust fan, heated towel rails, lighting, and any in-floor heating thermostat connected. Electrician performs final fix and tests all circuits. |
| Week 4 | Finishing and Defects | Silicon joints applied and cured. Accessories (mirrors, toilet roll holders, hooks) installed. Defects inspection completed. Site cleaned and handed over. |
The reason you have no functioning bathroom until week 3 is that plumbing second fix and fixture connection cannot happen until tiling is fully complete and cured. This is not inefficiency; it is the correct sequence.
Bathroom Renovation Costs in Sydney 2026
| Band | Price Range | What You Get |
| Entry-level full renovation | $20,000–$35,000 | Full strip and refit, same layout. Ceramic or porcelain tiles, standard vanity and tapware, basic shower screen and toilet suite. Licensed waterproofing and compliant fitout. |
| Mid-range full renovation | $35,000–$65,000 | Quality tile selection including larger formats, semi-custom or furniture vanity, mid-range tapware (Caroma, Methven, Fienza), frameless or semi-frameless screen, heated towel rail. |
| High-end / prestige renovation | $65,000–$120,000+ | Stone or large-format porcelain slabs, custom joinery, imported tapware (Brodware, Phoenix, Gessi), smart toilet, in-floor heating, bespoke shower niche, potentially structural or layout changes. |
What Drives the Cost
Stone vs tile. Porcelain or ceramic tile on a bathroom floor costs a fraction of a honed marble or engineered stone slab. The material cost difference compounds with the additional labour time for large-format stone; cutting, setting, and sealing stone is not the same trade as standard tiling.
Custom vs standard joinery. A floating vanity from a tile showroom and a custom-built cabinetmaker vanity with a stone top are not in the same price category. Both are legitimate choices; just know what you are specifying.
Fixture brands. A quality tapware package from an Australian manufacturer sits at $800–$2,000. Imported European fixtures from brands like Hansgrohe, Dornbracht or Vola start at two to three times that figure, before installation.
Plumbing relocation. If your waste points move, costs increase. If your building has a concrete slab requiring core drilling, they increase further. In a ground-floor house this is a known but manageable cost. In a multi-storey strata building, access arrangements, protection of the unit below, and strata requirements add both time and cost.
Access difficulty. Heritage-listed properties, narrow access lanes, high-rise apartments with goods lift time restrictions, and difficult ceiling heights all add preliminaries cost. This is rarely discussed upfront but it affects your price.
Why Sydney Bathrooms Often Take Longer Than Expected
Failed Waterproofing Discovered on Demo
Older bathrooms, particularly those built before the widespread adoption of membrane systems, often have no effective waterproofing under the tiles. Once demolition begins, the extent of substrate damage caused by years of water ingress becomes clear. In severe cases, subfloor framing or concrete substrate requires remedial work before waterproofing can proceed. This is not the builder’s fault; it is what was there before.
Asbestos in Pre-1987 Homes
Many homes and apartments built before 1987 contain asbestos-cement sheeting used as a wet area substrate. Under NSW regulations, licensed asbestos removal is required before work proceeds. An asbestos removalist, safe disposal, and air monitoring add time (typically 1–3 days minimum) and cost to the project. If your home was built before 1987, assume asbestos is present until a licensed inspector confirms otherwise.
Supply Chain on Imported Tiles and Fixtures
Australia does not manufacture most premium bathroom products. Tiles imported from Italy or Spain, tapware from Germany or France, and custom stone from quarries overseas all carry lead times that are entirely outside the builder’s control. If you see something you want on a trip overseas or on an Instagram feed, confirm availability and lead time before finalising your specification, not after demolition starts.
Strata Working Hours and Noise Curfews
In Eastern Suburbs and Bayside apartment buildings, strata by-laws typically restrict noisy works to 8am–5pm Monday to Friday, with no power tools on weekends. Some buildings are stricter. On a 3–4 week renovation, this restriction is workable but it means a day’s work is capped. Compare this to a freestanding house where an early start or a Saturday may be available to recover programme. It is a real difference that your builder should account for in the programme, not explain away after the fact.
Questions to Ask Your Builder Before Signing
What does the programme look like week by week? A builder who has done this before can show you a realistic schedule. Vague answers about “a few weeks” are a red flag.
Is this a fixed price or does it include provisional sums? Many quotes include provisional sums for tiles and fixtures, which means the final price depends on what you choose. Understand which line items are fixed and which are estimates before you sign.
Who is managing the trades? On a bathroom renovation, the licensed builder coordinates the plumber, waterproofer, tiler, electrician, and fit-off. If you are being quoted by someone who expects you to source and manage individual trades, you are acting as the project manager, with all the schedule and liability risk that comes with it.
Have you worked in strata buildings in this area? Experience with OC approvals, noise restrictions, and lift access in strata buildings is not the same as experience in freestanding homes. Ask for examples.
What happens if you find asbestos or substrate damage? Know how variations are priced before you are in the middle of demolition.
