If you’re planning a bathroom renovation in Sydney, hiring the right plumber isn’t just a good idea; it’s essential. A great bathroom design is nothing without sound plumbing behind the walls, under the floors, and in every fitting.
Yet all too often, homeowners jump in with the wrong tradesperson and end up with costly mistakes, water damage, compliance issues, or delays. That’s why knowing the right questions to ask before hiring a plumber can save you serious stress and money.
Here’s your essential 7-question checklist to help you choose the right bathroom renovation plumber in Sydney, and why STS Plumbing is the trusted choice for North Shore homes.
1. Are you licensed and insured?
Why it matters: In NSW, any bathroom renovation involving plumbing must be carried out by a licensed plumber. Unlicensed work isn’t just illegal; it can void your insurance and lead to major headaches if things go wrong.
Ask to see the plumber’s licence and check it against the NSW Fair Trading database. Insurance is equally important. Your plumber should have current public liability insurance and workers' compensation coverage.
How STS Plumbing ticks the box: We are fully licensed and insured, and we hold a Kitchen, Bathroom, and Laundry Renovators Licence, meaning we can carry out every stage of your renovation legally and professionally.
2. Can you show me examples of recent bathroom renovations?
Why it matters: Seeing a plumber’s past work gives you a real sense of their quality, attention to detail, and style. It also demonstrates that they’re experienced with renovations, not just basic maintenance work.
Look for evidence of tidy pipework, seamless fixture installations, and functional designs that match client needs.
How STS Plumbing ticks the box: We’ve completed hundreds of bathroom renovations across Sydney’s North Shore. From compact en-suites to full family bathrooms, our work speaks for itself. Ask us to show you photos and case studies from similar projects in your area.
3. Do you provide a detailed quote and scope of work?
Why it matters: A written quote helps prevent misunderstandings and gives you something to compare against other providers. It should include labour, materials, timeline, and any exclusions.
Beware of vague estimates or plumbers who are reluctant to put things in writing. These are often red flags for budget blowouts.
How STS Plumbing ticks the box: We’ll provide you with a comprehensive quote following a site visit, outlining everything from demolition and pipework to waterproofing and fit-off. No guesswork, just a clear roadmap.
4. Who manages the project and the other trades?
Why it matters: A bathroom renovation involves more than just plumbing. You’ll need tilers, electricians, waterproofers, and possibly carpenters. If your plumber isn’t managing the full project, you could be left coordinating trades yourself, which quickly becomes overwhelming.
How STS Plumbing ticks the box: We offer complete bathroom renovation project management from start to finish. We coordinate all licensed trades and ensure every stage runs smoothly and on schedule.
5. What warranties and guarantees do you provide?
Why it matters: A reputable plumber will stand behind their work with a workmanship guarantee. In NSW, waterproofing and structural work must meet strict Fair Trading standards and should be backed by a warranty of at least 6 years.
Ask for this in writing before work begins.
How STS Plumbing ticks the box: We offer a 7-year warranty on all workmanship, plus product warranties from leading brands. You’ll also receive all compliance certificates as part of your renovation handover.
6. Do you handle council approvals or strata coordination if needed?
Why it matters: If your home is part of a strata complex, or if you’re making significant changes to layout or drainage, council or strata approvals may be required. A knowledgeable plumber will help guide you through this and provide the necessary documentation.
How STS Plumbing ticks the box: We’re experienced with strata and council requirements across the Lower North Shore and can provide plans, insurances, and support with applications if needed.
7. How will you protect my home during the renovation?
Why it matters: Renovations can be messy. Without proper protection, your floors, walls, and other parts of your home can get damaged during the work. A professional plumber should take steps to safeguard your space.
How STS Plumbing ticks the box: We treat your home with care. From drop sheets and dust protection to final cleaning services, we’ll ensure your bathroom renovation doesn’t leave a trail of destruction.
Bonus Tip: Don’t choose a plumber based on price alone
It might be tempting to go with the cheapest quote, but in plumbing, you often get what you pay for. A cut-price contractor may skip licensing, take shortcuts, or install inferior fixtures that don’t last.
Instead, look for experience, credentials, clear communication, and a plumber who genuinely understands renovation. You’re not just building a bathroom, you’re investing in the long-term value of your home.
