The parts you don't see are the ones that matter.
The parts of a bathroom renovation people choose are the tiles and the tapware. The parts that determine whether it’s still sound in fifteen years are the drainage falls, the waterproofing and the rough-in — and those are all plumbing.

Voyager handles the plumbing side of bathroom renovations across the North Shore, from moving services to final fitout and certification.
Strip-out and disconnection Safe removal and capping of existing services before demolition.
Rough-in New water supply and drainage set out for the new layout. This is the stage that’s buried behind walls and under the floor, and the stage that’s expensive to revisit.
Relocating fixtures Moving a toilet, shower, bath or vanity means moving drainage, and drainage needs fall. Some moves are straightforward; others are constrained by where the waste can run — particularly on a concrete slab or in an apartment. Worth establishing early, because it shapes the design.
Waterproofing considerations Waterproofing must be done correctly and to standard. Falls to the waste, and the interaction between the membrane and the drainage outlets, are where bathrooms fail — and a failed shower membrane is a full re-do, not a repair.
Fitout Installing the new toilet, vanity, tapware, shower, bath and any heated towel rail or similar.
Testing and certification Everything tested, and compliance certification where required.
Worth knowing before you plan, because these are the recurring ones:
Describe what’s happening and we’ll tell you straight — including when the simple fix is the whole job.
Renovating a bathroom in a pre-war or mid-century North Shore home reliably turns up something: galvanised supply lines at the end of their life, cast iron or earthenware waste, old vent arrangements, or previous work that doesn’t meet current standards.
None of it is a disaster if it’s found early. All of it is expensive if it’s found after the tiler has finished. A pre-renovation inspection of what’s behind the walls is worth doing before the design is locked in — and while you can still change your mind cheaply.
Bathroom renovations in strata usually need owners corporation approval, and there are practical constraints a house doesn’t have: slab drainage limits where a waste can go, common property services may run through your bathroom, and there are usually rules about noise, hours and waterproofing certification.
Voyager works with strata across the North Shore and can advise on what’s feasible before you commit to a layout.

Voyager handles the plumbing scope — strip-out, rough-in, fitout, testing and certification — and coordinates with the other trades on site. Talk to the team about how your particular job is best structured.
Often, but it depends on where the drainage can run and what fall is achievable. On a concrete slab or in an apartment the constraints are tighter. Establish this before the design is finalised, not after.
It’s staged rather than continuous — rough-in early, fitout at the end, with tiling and waterproofing in between. The plumbing days are a fraction of the overall program, but they gate everything else, so sequencing matters.
In a strata building, almost certainly from the owners corporation. For a house, it depends on the scope. Voyager will flag what’s likely to be needed.
You’ll be told what’s there, what condition it’s in and what replacing it would cost, before it’s covered up. Replacing tired supply lines during a renovation is far cheaper than doing it through a finished bathroom later.
Yes, for work that requires it. In NSW, plumbing and drainage work comes with a compliance certificate, and waterproofing is certified against the Australian Standard (AS 3740). Keep both — they matter for insurance and at sale.
