Frequently asked questions
How much does a bathroom renovation cost in Central Coast?
In Central Coast, a bathroom renovation typically costs between $18,025 and $36,050 in 2026, with most projects landing around $26,780. Pricing varies with size, finish level, complexity and your specific site.
How long does a typical bathroom renovation take?
A standard strip-out and refit is usually 3–5 weeks on site once trades start. Layout changes, custom tiling or premium fixtures can extend the timeline.
Do I need council approval?
Most like-for-like bathroom renovations are exempt or fall under complying development. Structural changes, moving wet areas, or work in heritage zones may require approval.
Why are bathrooms so expensive per square metre?
Bathrooms pack the highest density of trades — plumbing, electrical, waterproofing, tiling, joinery, glazing — into a small space. Almost every surface is wet-area certified, which adds compliance cost.
Will moving the toilet or shower really cost that much extra?
Yes. Relocating fixtures means new drainage falls, opening floors or walls, and (often) waterproofing the whole room again. Plan around existing plumbing where possible.
Which parts of the job legally need licensed trades?
Plumbing and electrical work must be done by licensed trades everywhere in Australia, and most states also require waterproofing to be carried out or certified by a licensed applicator. Ask for the compliance certificates at handover, as you'll need them for insurance and resale. In several states the overall job also requires a licensed builder once it exceeds a value threshold.
How do I compare quotes properly?
Make sure each quote covers the same scope: demolition and disposal, waterproofing, tiling to the same height, fixtures supplied versus owner-supplied, and who handles certificates. A quote that looks cheaper often excludes items like niches, shower screens or a contingency for hidden water damage. Ask each builder to itemise inclusions and provisional sums so you're comparing like for like.
