Key Cost Drivers
1. Tiling: the single biggest cost — floor-to-ceiling tiles in a 4 sqm bathroom = 25–30 sqm of tile area. Tiles $30–$100/sqm, labour $60–$90/sqm. 2. Waterproofing: $1,500–$3,000 for a standard bathroom. Mandatory under NCC. 3. Plumbing: relocating fixtures adds $3,000–$8,000. Like-for-like replacement minimises cost. 4. Fixtures: vanity ($500–$3,000), toilet ($300–$1,500), shower mixer ($200–$800), bath ($800–$5,000). 5. Structural: moving walls, enlarging the bathroom, or converting a bath to walk-in shower may require structural modifications ($3,000–$10,000).
