- Cracked or drummy tiles, or grout that keeps going mouldy
- Water stains below the bathroom or on the other side of the wall
- A dated layout that doesn't work for how you live now
- A bath nobody uses that could be a bigger walk-in shower
- You're getting ready to sell or rent the place out
What does a full bathroom renovation include?
Strip-out and disposal, any framing or sheeting repairs, plumbing and electrical rough-in, waterproofing to AS 3740, screeding and tiling, then fit-off: vanity, toilet, shower screen, tapware, lights and exhaust fan. A good quote lists each of these stages with a price.
The biggest cost jump comes from moving things. Keeping the toilet, shower and vanity where they are saves on plumbing; moving them, or turning a bath into a walk-in shower, adds to it.
How long does a bathroom renovation take?
Most full bathroom renovations take three to five weeks of work on site, longer for bigger or custom jobs. Waterproofing needs time to cure before tiling, and good renovators don't rush that stage. Ask for a stage-by-stage timeline in the quote.
Who needs to be licensed?
In NSW, any residential building or trade work over $5,000 needs a contractor licence, and kitchen, bathroom and laundry renovation is its own licence category. Waterproofing over $5,000 needs a waterproofing licence. Plumbing and electrical work need a licence regardless of price. You can check any licence on Service NSW.
Contracts, deposits and insurance
Any home building job over $5,000 needs a written contract, and the deposit can't be more than 10% of the price. Over $20,000, the renovator must take out Home Building Compensation cover and give you the certificate before taking a deposit. Most full bathroom renovations are over that line.

The standard we ask of every renovator we refer you to
The renovator does the work, not us. Ask for each of these in your written quote and contract.
- A renovator licensed in NSW for the work, with public liability insurance (certificate on request)
- Waterproofing by a licensed waterproofer to AS 3740, with a certificate you keep
- Plumbing and electrical done by licensed plumbers and electricians
- A written, itemised quote: demolition, waterproofing, tiling, fixtures and labour listed
- A written contract for any job over $5,000, with a deposit of no more than 10%
- Home Building Compensation cover for jobs over $20,000, before any deposit
- Photos of the waterproofing before it is tiled over, and a walk-through at handover
Photos of the waterproofing, and a written scope
Waterproofing is hidden under the tiles once the job is done. You get photos of the membrane before tiling and the waterproofing certificate, plus a written scope before anything starts.

A bathroom done properly, by licensed trades
A bathroom that looks good but leaks behind the tiles means paying twice. That's why every job we pass on goes to a licensed, insured Northern Beaches renovator who agrees to this standard before they get the work.
Licensed for the job
In NSW, bathroom renovation and waterproofing work over $5,000 needs a contractor licence, and plumbing and electrical work need a licence at any price. Jobs only go to renovators who hold the right licences and insurance.
Waterproofing done properly
Waterproofing is the cheapest part of a bathroom and the most expensive to get wrong. It is done to AS 3740 by a licensed waterproofer, flood-tested where appropriate, and photographed before it is tiled over.
An itemised price first
You get the scope and price in writing, broken down by stage, before work starts. Under NSW law, any variation to the contract should be agreed in writing.
Contracts and insurance
A written contract for jobs over $5,000 with a deposit capped at 10%, and Home Building Compensation cover over $20,000, as NSW law requires.
Strata handled up front
In a unit, a bathroom renovation needs owners corporation approval. The renovator should help with the paperwork your strata manager asks for.
A realistic timeline
You get a start date and a stage-by-stage timeline, including curing time for waterproofing, so you know how long you'll be without a bathroom.
Left clean
Ask for demolition waste to be taken away, dust controlled, and the house left clean at the end of each day and at handover.
