Common questions
How long does a bathroom renovation take?
A mid-range renovation typically takes 3–6 weeks from demolition to completion, depending on material lead times and trade availability. Renovations with structural changes can take 8–12 weeks.
Do I need a licensed plumber?
Yes. All plumbing and drainage work in Australia must be done by a licensed plumber. Electrical work such as heat lamps or underfloor heating requires a licensed electrician. Always ask for a Certificate of Compliance when the job is done.
What is waterproofing and why does it matter?
Waterproofing is a legal requirement in Australia under AS 3740. A licensed waterproofer must seal shower and wet areas before tiling. Skipping or cutting corners on waterproofing is one of the most common causes of costly long-term water damage.
