Bathroom Renovation in Craigieburn

If the renovation strips the shower area back to the substrate, waterproofing must be redone — a failed membrane is the most expensive bathroom defect there is, because the fix means demolishing finished tiling. Several countries regulate wet-area waterproofing explicitly. Never let a contractor tile directly over an old or damaged membrane.

Relocating a toilet means rerouting the soil pipe and adjusting floor levels; moving a shower means new drainage falls and full re-waterproofing. Either typically adds a meaningful share of the total budget and extra days of work. If your budget is tight, keeping the existing layout is the single most effective cost-saver.

Only in limited ways. Swapping a vanity, toilet, or taps in place works as standalone jobs, but anything touching the shower area, waterproofing, or tiling should be done in one hit — redoing tiles twice or breaking a waterproof membrane to add something later costs more than doing it together.

A straight swap-in-place refit takes about 1-2 weeks; a full renovation with new waterproofing, retiling, and any layout change takes 2-4 weeks. Add waiting time before the start for fixture delivery and trades scheduling — and note that waterproofing membranes need curing days you cannot compress.

The HIA Kitchens and Bathrooms Report puts the median around AUD 26,000-27,000, with budget renovations from about AUD 10,000-15,000 and premium projects AUD 35,000-80,000. Waterproofing, licensed trades, and certification requirements make Australian bathrooms pricier than comparable UK/US work.

State law prohibits unlicensed plumbing and electrical work — fines apply and your home insurance can refuse claims arising from it. DIY is fine for demolition, painting, and assembly-type tasks; everything touching water, waste, or wiring must be a licensed trade with compliance certificates.
