Bathroom Renovations in Illawarra

Residential bathroom renovation plumbing covers all plumbing work required when renovating, remodelling or upgrading a bathroom — from disconnecting and removing old fixtures through to installing new pipework, drainage, and fitting all new fixtures. In Illawarra, bathroom renovation plumbing costs $3,000-$8,000 for a standard bathroom. A like-for-like fixture replacement with no pipe relocation costs $2,000-$4,000. A full re-plumb with new pipe runs, drainage relocation and all new fixtures costs $5,000-$8,000. Adding a new ensuite or second bathroom costs $6,000-$12,000 for plumbing alone. The plumbing scope typically includes strip-out of existing fixtures and plumbing, rough-in of new hot and cold water supply lines (typically in PEX or copper), drainage installation or relocation (may require cutting a concrete slab), gas pipework for heated towel rails or gas hot water, coordination with the waterproofer before tiling (critical — plumbing penetrations must be waterproofed to AS 3740), and fit-off of all new fixtures including shower, bath, toilet, basin, tapware and accessories. Bathroom plumbing must be completed in the correct sequence — rough-in before waterproofing and tiling, fit-off after. A licensed plumber coordinates with the builder, waterproofer, tiler and electrician to ensure every step happens in the right order.
