Planning abathroom reno on the Central Coast? You're in good company. From Gosford andTerrigal to Wyong, The Entrance and Woy Woy, more locals are choosing torenovate and stay put rather than take on a new mortgage.
But there's onedecision that matters more than the tiles, the tapware or the vanity: whoyou hire.
A bathroom isone of the most technical rooms in the house. It has plumbing, electrical,waterproofing, ventilation and tiling all packed into a few square metres. Getit wrong and you could be looking at leaks, mould and a very expensive redo.This guide covers what a licensed bathroom renovator actually is, what tocheck, what you'll likely pay and which trends are worth your money.
WhyHiring a Licensed Bathroom Renovator Matters in NSW
In NSW, youneed a licence before you do any residential building work, including kitchen,bathroom and laundry renovations, valued at more than $5,000 (including GST) inlabour and materials. Since most bathroom renos blow past that figure, alicence isn't optional. It's the law.
Here's what alicence gets you:
• Statutory warranty protection. NSW homeownersare protected by statutory warranties under the Home Building Act 1989, andthese can't be excluded.
• Insurance backup. For projects over $20,000,licensed builders must also provide Home Building Compensation Fund insurance.If your builder disappears or goes insolvent, this is your safety net.
• Qualified specialists on the job. Specialistwork can be subcontracted, but it must be carried out by the holder of anendorsed contractor licence or qualified supervisor certificate in thatspecialist category. In plain English, your plumber should be a licensedplumber and your sparky a licensed electrician.
WhyWaterproofing Is the Big One
If you onlyremember one thing from this post, make it this: waterproofing is wherecheap bathroom renos go wrong.
All bathroomwaterproofing must comply with AS 3740, the Australian Standard forwaterproofing domestic wet areas. Poor waterproofing might not show up formonths. Then you notice a damp patch on the hallway wall, a musty smell orlifting floorboards, and by then the damage is done.
The coast addsits own challenges. Coastal humidity, salty air and older homes with tired ornon-existent exhaust fans all make good waterproofing and ventilation even moreimportant here than in drier inland areas.
A licensedrenovator will:
• Waterproof the whole wet area to standard, not just theshower recess
• Use quality membranes and allow proper curing time
• Provide a waterproofing certificate when the job isdone
• Make sure ventilation is up to scratch
Howto Check a Bathroom Renovator's Licence (Takes 2 Minutes)
Don't just takesomeone's word for it. NSW Fair Trading offers a free online database to verifylicences. Here's your checklist:
1. Get the licence number from their quote,contract, website or ute.
2. Look it up on the NSW Fair Trading licence check. Confirmthe licence is current and the class of licence suits bathroom work.
3. Ask for insurance certificates. You want publicliability, workers' compensation and, for jobs over $20,000, home warrantyinsurance.
4. Check the contract. It should include thecontractor's licence number, insurance details and ABN.
5. Know your cooling-off rights. For contractssigned away from trade premises, you may have five business days to withdraw.
Red flags: no licence number on thequote, pressure to pay a big deposit upfront, "cash only" deals, or aquote that's thin on detail.
HowMuch Does a Bathroom Renovation Cost in NSW?
Every bathroomis different, so treat these as ballpark figures only. Based on NSW-wideindicative ranges, a bathroom refresh sits around $20,000 to $35,000, while afull bathroom overhaul runs from about $30,000 to $60,000 or more.
What pushes theprice up or down?
• Size and layout. Moving the toilet, shower orvanity means moving plumbing, which costs more.
• Tiles. Large-format and natural stone tiles costmore to supply and lay.
• Fixtures. A basic vanity and a custom stone-topstatement piece are worlds apart.
• Hidden surprises. Rotted subfloors and old pipesoften only show up once demolition starts.
• Access. Second-storey bathrooms and tight sitescan add labour time.
Pro tip: make sure every quotereferences the same specifications, especially waterproofing systems, so you'recomparing apples with apples. The cheapest quote often leaves things out thatthe dearer ones include.
BathroomTrends Homeowners Are Choosing in 2026
Here's what'spopular right now and still looks good in ten years.
1. Warm, spa-styleminimalism
This is thebiggest shift. Bathrooms are becoming spa-inspired, wellness-focused spacesbuilt around comfort, relaxation and long-term value. Think soft neutrals likebeige and warm grey, stone-look tiles, timber vanities, frameless glass andfloating fixtures. It's a natural fit for a laid-back coastal lifestyle.
2. Large-formattiles
Large-formattiles have largely replaced small tiles in new builds and renovations. Fewergrout lines mean a cleaner look and less scrubbing, which is a win in humidcoastal bathrooms.
3. Colour is back
Designers arepointing to pink marble, pale blue, brick-look tiles, neutral terrazzo andsmall square tiles as key looks of 2026. Pale blue is a particularly good matchfor a beachy feel.
4. Statementvanities and gunmetal tapware
The bathroomvanity has become a hero piece, with gunmetal tapware finishes growing inpopularity. It's an easy way to add personality without a full renovation.
5. Smart touches
LED mirrors arenow close to standard, and bidet toilets have gone mainstream. Heated floorsand smart lighting are also popular upgrades.
6. Natural light andgreenery
Skylights, awindow to the garden and a few moisture-loving plants bring that biophilic,resort feel.
