Your bathroom is one of the most-used rooms in your home — and one of the first things buyers, guests, and your own family notice. When the grout is crumbling, the tiles are cracked, the layout no longer works, or you’ve spotted the early signs of water damage behind the walls, a bathroom renovation isn’t a luxury. It’s a necessary investment in your home’s value, your family’s comfort, and your peace of mind.
At Sydney Home Renovation, we’ve been transforming outdated, tired, and damaged bathrooms into beautiful, functional spaces for Sydney homeowners for over 15 years. From compact ensuite refreshes in Bondi Junction apartments to full bathroom rebuilds in Parramatta family homes, we handle every aspect of your renovation — design, demolition, waterproofing, tiling, plumbing, and final fit-out — under one fixed-price contract.
We’re a licensed NSW builder with AS 3740 waterproofing compliance on every job, a 5-year workmanship warranty, and a reputation built on showing up, communicating clearly, and delivering exactly what we quoted. If you’re ready to stop putting up with a bathroom that’s letting you down, we’re ready to fix it.
Sydney's humid coastal climate is hard on bathrooms. If you're seeing black mould returning within weeks of cleaning, grout that's crumbling or discoloured beyond recovery, or silicone seals that have shrunk and cracked, these aren't cosmetic problems. They're signs that moisture is penetrating surfaces it shouldn't reach. Left untreated, mould spreads into wall cavities and subfloors, turning a manageable renovation into a major structural repair. A full bathroom renovation with proper waterproofing eliminates the root cause — not just the visible symptom.
A bathroom designed for a 1980s household rarely suits a modern Sydney family. If your bathroom feels cramped, lacks storage, has a bath you never use, or simply doesn't function the way your household needs it to, a renovation is the only real solution. Reconfiguring the layout — moving the vanity, replacing a bath with a walk-in shower, or adding a double basin — can transform how your entire morning routine feels. This is one of the most common reasons Sydney homeowners contact us, and the results are consistently life-changing.
Water stains on the ceiling of the room below your bathroom, soft or spongy flooring, peeling paint on adjacent walls, or a persistent musty smell are all signs that your bathroom's waterproofing has failed. In NSW, waterproofing must comply with AS 3740 — and many older Sydney homes were built before this standard existed, or with waterproofing that has simply reached the end of its lifespan. Ignoring these signs doesn't make them cheaper to fix. Every week of delay allows water to travel further into your home's structure.
Cracked or lifting tiles, a vanity that's warped or stained beyond cleaning, taps that drip regardless of how many times they've been repaired, or a shower screen that's permanently fogged — these are the everyday frustrations that accumulate until the bathroom becomes a source of daily irritation rather than comfort. When multiple fixtures and surfaces are failing simultaneously, individual repairs become more expensive than a coordinated renovation that addresses everything at once.
The most expensive bathroom renovations we see in Sydney are the ones that were delayed. What starts as a cracked tile or a slow-draining shower can become a waterproofing failure, a mould infestation, and structural water damage within 12–18 months. If you're recognising two or more of these signs in your Sydney home, an inspection costs nothing and gives you a clear picture of what you're actually dealing with.
Our most comprehensive service covers everything from demolition to final fit-out. We strip the bathroom back to the structural substrate, apply AS 3740-compliant waterproofing membranes, and rebuild with your chosen tiles, fixtures, vanity, shower, and accessories. This is the right solution when your bathroom has waterproofing failure, significant water damage, or is simply too outdated to be salvaged with partial repairs. Most full bathroom renovations in Sydney are completed within 2–3 weeks, with a single point of contact managing every trade.
Ensuites present unique challenges — they're typically smaller, often attached to the master bedroom, and need to be completed with minimal disruption to the rest of the household. Our ensuite renovation service is designed for efficiency without cutting corners. We work to a tight schedule, protect your bedroom and surrounding areas throughout the process, and deliver a finished ensuite that feels like a boutique hotel bathroom rather than an afterthought. Popular in Chatswood, Strathfield, and Castle Hill family homes where the ensuite is a key selling point.
Sydney's ageing population and growing awareness of universal design has driven significant demand for accessible bathroom conversions. We design and build bathrooms that meet AS 1428 accessibility standards — including step-free shower entries, grab rail installation, wider doorways, comfort-height toilets, and non-slip flooring — without sacrificing the aesthetic quality of the space. Whether you're planning ahead or responding to an immediate need, we approach accessible bathroom design with the same attention to detail as any premium renovation.
Renovating a bathroom in a Sydney apartment or strata building involves additional considerations — strata by-laws, waterproofing obligations, noise restrictions, and building management approvals. We've completed bathroom renovations across Sydney's apartment-dense suburbs including Surry Hills, Randwick, Bondi Junction, and Manly, and we understand exactly what's required to keep your renovation compliant and your neighbours onside. We handle the paperwork, manage the approvals process, and work within strata-approved hours.
There’s no shortage of renovation companies in Sydney. Here’s why our customers keep choosing us — and referring their neighbours.
A compact 3m² ensuite costs considerably less than a 7m² main bathroom with a separate bath and shower. Layout changes — moving plumbing, relocating walls — add cost but often deliver the greatest functional improvement.
Tiles are one of the most variable cost elements. Budget-range tiles from $30/m² to premium imported tiles at $200+/m² can represent a $3,000–$8,000 difference on a standard bathroom. We guide you through options at every price point.
A builder-grade vanity, toilet suite, and tapware package differs substantially from a designer specification. We work with suppliers across the full quality spectrum and help you allocate budget where it matters most.
If your existing bathroom has waterproofing failure or water damage, additional substrate preparation and remediation work is required before new waterproofing can be applied. This is non-negotiable for compliance and longevity.
Apartment renovations in Sydney may require strata approval, additional noise mitigation, or specific waste management arrangements, which can affect project cost and timeline.

Bathroom renovation costs in Sydney typically range from $12,000–$18,000 for a budget cosmetic refresh through to $28,000–$45,000+ for a premium renovation with designer fixtures, complex tiling, and structural changes. The key cost drivers are bathroom size, tile selection, fixture quality, waterproofing requirements, and whether any layout changes are involved. The most accurate way to understand your cost is a free measure-and-quote visit — we provide a detailed fixed-price quote within 48 hours, with no obligation.
If you're dealing with a single isolated issue — a dripping tap, a cracked tile, a faulty exhaust fan — repairs are likely sufficient. However, if you're seeing multiple failing elements simultaneously (grout deterioration, mould, leaking fixtures, outdated aesthetics), or if there's any evidence of waterproofing failure or water damage, a full renovation is almost always more cost-effective than piecemeal repairs. Our free inspection gives you an honest assessment of which approach makes sense for your specific bathroom.
Most like-for-like bathroom renovations in Sydney — where you're renovating within the existing footprint without structural changes — can proceed as exempt development and don't require a DA or CDC. However, if your renovation involves structural changes, moving load-bearing walls, or significant alterations to the building envelope, council approval may be required. For apartment renovations, strata by-law approval is typically needed regardless of scope. We advise you on approval requirements during your consultation and can assist with the documentation process.
AS 3740 is the Australian Standard for waterproofing of wet areas in residential buildings. It specifies the minimum requirements for waterproofing membrane systems, application methods, and coverage areas in bathrooms, ensuites, and laundries. Compliance with AS 3740 is a legal requirement in NSW for all bathroom renovation work. When we say every Sydney Home Renovation project is AS 3740 compliant, it means your waterproofing has been applied correctly by a licensed waterproofer and certified to the standard — protecting your home from water damage for the long term.
Yes — consistently and significantly. Mould spreads through wall cavities and subfloors at a rate that accelerates with each wet season. What appears as surface mould on grout can indicate a much larger colony behind the tiles. Similarly, waterproofing failure allows water to travel laterally through floor and wall substrates, causing timber rot, concrete spalling, and damage to adjacent rooms. In our experience, a bathroom renovation that costs $20,000 today can become a $35,000+ project if structural water damage is allowed to develop over 12–24 months.
In Australian usage, these terms are often used interchangeably. Technically, a renovation refers to restoring or updating an existing space — new tiles, new fixtures, new waterproofing — while a remodel implies structural changes to the layout or footprint. At Sydney Home Renovation, we handle both: cosmetic renovations that update the look and function of your existing bathroom, and full remodels that reconfigure the layout, move plumbing, or expand the space. We'll recommend the right approach based on your goals and budget.

Yes — we have extensive experience with bathroom renovations in Sydney apartments and strata-titled properties across suburbs including Surry Hills, Randwick, Bondi Junction, Manly, and Pyrmont.

You make the decisions; we handle everything else from concept through to completed renovation.
