Renovation Plumbing in Brisbane

Yes. Bathroom, kitchen, laundry and en-suite renovation plumbing is a regular part of what we do at Submerge Plumbing & Gas. We work both directly with homeowners and with builders, designers and bathroom companies. We can be the lead trade running the plumbing rough-in, fit-off and tiling-handover, or we can come in to do specific stages — whatever fits the way your renovation is being run.

Both. Many homeowners on smaller renovations directly manage the trades, and we coordinate with the tiler, electrician and cabinetmaker without the homeowner needing to chase. On a builder-run renovation we'll work through the builder's program. The fit-off stage particularly has tight ordering — taps, basin, toilet need to land in the right order around tiling — and we plan that in writing before site work starts.

Yes. Moving a toilet, shower or basin requires re-running drainage and water supply lines, which is more complex than a fitting swap but absolutely doable. The cost depends on access — under-floor versus slab, single versus second storey — and we tell you upfront whether the move you want is a small change or a meaningful one. Sometimes a 200mm shift saves significantly versus relocating the entire fixture.

We quote renovation plumbing as a fixed price for the rough-in stage and a separate fixed price for the fit-off stage. There's a single line item for any extras you ask us to add later. This is more honest than hourly billing on a renovation because you know the plumbing budget early, and you can compare quotes from different plumbers like-for-like. The quote breaks down what's included to the level of fittings.

Either works. Many homeowners pick the taps, basin and toilet themselves to control aesthetic and budget. We're happy to install client-supplied fittings (with a quick check that they're compliant for Queensland — not all imported fittings are). If you'd rather we supply, we'll quote at trade pricing with a small handling margin and handle the warranty registration. Either path, the install workmanship is guaranteed.

Rough-in is typically one to two days for a single bathroom, after which the room is handed to the tiler and waterproofer. Fit-off is another full day after tiling, when the taps, toilet, basin and shower are installed. Total plumbing time on-site is three to four days spread across the renovation timeline. We'll align our days to your tiler's schedule because waiting for tiling is the most common renovation delay.

Bathroom renovations involving regulated work (drainage changes, hot water relocation) require a notifiable work certificate lodged with the QBCC — not a council inspection per se. We lodge the certificate as the licensed plumber for any qualifying work, and you get a copy. Insurance and any future buyer will look for it. If your renovation falls below the notifiable threshold, no certificate is needed but we still issue you a workmanship summary.
