All advice / Planning and cost
The short answer
A well-planned bathroom renovation typically returns 60 to 80 percent of its cost at resale. The exact figure depends on the suburb, the property price, and how dated the existing bathroom was before the work.
That makes bathroom renovations one of the higher-return improvements you can make to a home in Sydney, alongside kitchens and street appeal. But returns are not guaranteed, and spending more does not automatically mean getting more back.
Why bathrooms influence buyers
Bathrooms signal upkeep. A buyer walking through a home with a tired bathroom starts calculating what it will cost to fix. That mental estimate often runs higher than the actual renovation price, because most buyers overweight the disruption.
A clean, functional bathroom with good light, working ventilation and modern fittings removes that objection. It does not need to be luxurious. It needs to feel finished, maintained and ready to use.
Refresh vs full renovation
A cosmetic refresh — new tapware, a painted vanity, fresh silicone, better lighting — can cost under $5,000 and still shift the impression of a room on sale day. It will not fix layout problems, poor waterproofing or failing plumbing, but it can remove the "dated" label.
A full renovation addresses the structure, waterproofing, layout, fixtures and finishes together. ETR package starting points begin at Basic from $18,000 for a roughly 1.5 m × 1.8 m bathroom, Standard from $25,000, and Premium from $30,000, each tied to a stated room size and inclusion list. These are starting prices, not fixed quotes — the final scope follows a free on-site measure. Our budget planning guide walks through how to set and hold a realistic number.
What actually adds value
Focus on what buyers notice and use every day: a working shower with good water pressure, enough storage, clean tiles, proper ventilation and a layout that makes sense for the room.
Waterproofing to AS 3740 is not visible after the tiles go on, but the certificate and the confidence it gives a buyer at due diligence can matter more than a statement tile wall.
How to avoid overcapitalising
A common guideline is to keep a bathroom renovation under 5 to 10 percent of the property value. A $60,000 bathroom in a $700,000 home is unlikely to return its cost, because buyers in that price bracket are not expecting that level of finish.
Match the bathroom to the home and the suburb. A solid mid-range renovation with good waterproofing, clean finishes and a sensible layout usually returns more of its cost than a high-end build in a modest property. We cover this in more detail in our guide to what agents actually look for at resale.
What should you ask before renovating for resale?
Ask whether the bathroom is the weakest room in the home. If the kitchen, exterior or structural issues are worse, fixing the bathroom may not shift the sale price as much as you hope.
Ask what level of finish comparable homes in the street already have. A renovation that brings the bathroom up to the local standard is usually the safest return. Going well beyond it is a personal choice, not a financial one.
What does a good renovation include for resale?
Clean layout, modern fittings, waterproofing done to standard, good lighting, proper ventilation, and a neutral finish that suits a broad range of buyers. That combination keeps the room functional without dating it quickly.
A fixed-scope written quote with clear inclusions helps you control the spend and compare what you are getting. A free on-site measure is the right starting point if you are weighing up whether the renovation makes financial sense for your home.
Frequently asked questions
How much value does a bathroom renovation add in Sydney?
A well-executed renovation typically returns 60 to 80 percent of its cost at resale. The exact return depends on the suburb, the property price point and how dated the existing bathroom was.
Is it worth renovating the bathroom before selling?
Usually yes, if the bathroom is the weakest room in the home. A dated bathroom makes buyers estimate a higher renovation cost than the actual price, which can reduce their offer by more than the renovation would have cost.
What bathroom features add the most value?
Clean layout, proper waterproofing, good ventilation, modern fittings and enough storage. These practical features matter more at resale than decorative upgrades.
How much should I spend on a bathroom renovation for resale?
A common guideline is 5 to 10 percent of the property value. Spending beyond that risks overcapitalising, where the renovation costs more than it adds to the sale price.
Does a new bathroom increase home value more than a new kitchen?
Both are high-return improvements. Kitchens typically cost more to renovate, so the percentage return can be similar. If the bathroom is in worse condition, it may offer the better return for the money.
