Why Homeowners Across Sydney Trust Us With Their Toilet Replacement
A toilet suite replacement is more involved than swapping a tap — it means disconnecting the water supply, removing the existing pan and cistern, setting the new suite to the correct height and fall, and re-sealing everything to prevent leaks at the base and the wall connection. OneBookPlus Plumbing handles every step in-house. We do not split the job between a plumber and a tiler or pass the work to a subcontractor. The same licensed plumber who quotes the job completes it. We carry a range of close-coupled and wall-faced suites on the van so most replacements are finished in a single visit, with no return call needed.

What is included
Everything Covered in a Toilet Suite Replacement
Removal of the existing toilet suite
We disconnect the water supply, remove the pan and cistern, and dispose of the old unit responsibly.
Supply and installation of the new suite
We carry close-coupled and wall-faced suites. You choose the model, or we recommend one suited to your rough-in measurement.
Pan collar and floor seal replacement
The pan collar and wax seal are replaced as standard — not reused — to prevent sewer odours and base leaks.
Water supply line inspection and connection
We inspect the existing flexi hose and isolating valve and replace them if they show wear, before connecting the new cistern.
Full flush and leak test
Every replacement is tested through multiple flush cycles and checked at all connection points before we leave.
Silicone seal at the base
We apply a neat silicone bead around the base of the new pan to prevent moisture getting under the suite between the pan and the tiles.

We measure the rough-in and confirm the suite
On arrival we measure your rough-in distance so the new suite fits correctly, and confirm the model with you before removing the old unit.
Old suite removed and new suite fitted
We disconnect and remove the existing toilet, replace the pan collar and seal, set the new suite, and connect the water supply.
Test, seal, and clean up
We flush-test the new suite, check every connection for leaks, apply the base silicone, and leave the bathroom clean.
What Sets Our Toilet Replacement Service Apart

Single-visit completion
The Job Is Finished the Day We Arrive
Unlike services that quote on one day and return to install on another, OneBookPlus Plumbing carries suites on the van and completes most toilet replacements in a single visit. That means no second booking, no day off work waiting for a return call, and no bathroom out of action overnight. We confirm suite availability when you book so there are no surprises on the day.
- Suites carried on the van for same-day fitting
- Rough-in measured before the old suite is removed
- No second visit required for standard replacements

No subcontractors
The Same Plumber Quotes and Completes Your Job
Some plumbing companies quote the job and then send a different tradesperson to do the work. At OneBookPlus Plumbing, the licensed plumber who assesses your toilet is the one who fits the new suite. That means the person doing the work already knows the condition of your pipework, the floor substrate, and any complications identified during the quote. There is no miscommunication between contractors and no hidden variations on the invoice.
- Licensed plumber on every job — no apprentice-only visits
- Quote and installation by the same person
- Upfront pricing confirmed before work starts
