Bathroom Renovation Plumbing in Sydney CBD

Bathroom renovations in the CBD come with constraints you will not find in suburban houses. Limited access for materials, strata bylaws governing wet work, noise restrictions during business hours, and heritage requirements on some buildings. We handle the plumbing side of CBD bathroom renovations from rough-in through to fixture installation, working alongside your builder or managing the entire job.

Our Bathroom Renovation Process

Design & Planning

We assess existing plumbing, drainage locations, and water pressure. We advise on fixture placement, pipe routing, and structural limitations. For apartments, we check strata requirements for waterproofing and noise restrictions.

Rough-In Plumbing

After demolition, we install new hot and cold supply lines, reposition waste pipes, and install shower and bath mixers to wall. All rough-in work is inspected and pressure tested before waterproofing begins.

Fit-Off & Commission

Once tiling is complete, we install all fixtures: toilet, vanity basin, shower, tapware, floor waste, and towel rails. Everything is connected, tested, and adjusted for proper flow and temperature.

Popular Bathroom Features for CBD Apartments

Walk-in showers — frameless glass panels with linear floor waste for a modern, open feel
Wall-hung toilets — concealed cistern saves space and makes floor cleaning easier
Freestanding baths — floor-mounted spout and waste connection for a centrepiece look
Heated towel rails — hydronic or electric, plumbed in during rough-in for a clean installation
Wall-mounted vanities — floating design with concealed plumbing in the wall cavity
Rain shower heads — ceiling or wall-mounted, requires adequate water pressure (minimum 200 kPa)

Waterproofing and Compliance

All bathroom renovations must comply with AS/NZS 3500 (plumbing and drainage) and AS 3740 (waterproofing). In strata buildings, you typically need owners corporation approval before starting wet area work. We coordinate with licensed waterproofers and provide the required plumbing compliance certificates for council and strata records.

Waterproofing is the most critical element. In a CBD apartment, a waterproofing failure means water leaking into the unit below — expensive and stressful for everyone involved. We ensure all waste connections, pipe penetrations, and shower recesses are properly sealed and tested before tiling begins.

Brands and Fixtures We Work With

We install tapware and fixtures from Caroma, Methven, Phoenix, Mizu, Fienza, Reece, and other leading Australian suppliers. If you have already purchased fixtures, we install them. If you need guidance, we recommend products based on your budget, style preference, and the water pressure available in your building. All fixtures carry the WaterMark certification required by Australian plumbing standards.

Frequently Asked Questions

A standard bathroom renovation in a CBD apartment takes 2-3 weeks from demolition to completion. The plumbing rough-in takes 1-2 days, then waterproofing needs time to cure before tiling begins. We coordinate our schedule with your builder and tiler to avoid delays.

In most Sydney CBD strata buildings, yes. Wet area renovations typically require owners corporation approval, a waterproofing certificate, and sometimes a plumbing compliance certificate. We advise on what documentation your strata requires and provide the necessary certificates.

Yes, within the constraints of the existing drainage system. Moving a toilet requires access to the waste pipe below the floor slab, which is possible in most buildings. Shower relocation depends on fall requirements for drainage. We assess feasibility during the design stage.

Plumbing costs for a CBD bathroom renovation typically range from \$3,000 to \$8,000 depending on scope. A like-for-like fixture replacement is at the lower end. Relocating fixtures or changing pipe routes increases the cost. We provide a detailed fixed quote after the design consultation.

We specialise in the plumbing component and work alongside your builder, tiler, and waterproofer. If you do not have a builder, we can recommend trusted renovation teams we regularly work with on CBD apartment projects.
