Typical Australian planning ranges
Many Australian bathroom projects sit in a broad AUD 8k-35k+ planning range, with higher costs for layout changes and premium finishes.
A common national planning range is AUD 80k-160k, before site-specific approvals, services, access and finish choices.
Final prices can move materially after a builder checks access, structure, plumbing, waterproofing and local labour.
