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.

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

Toilet Suite Replacement — Common Questions

How long does a toilet suite replacement take?
Most standard toilet suite replacements take between one and two hours. If the isolation valve or the waste connection needs attention, allow a little extra time. We will give you a realistic time estimate when you book.
Do I need to supply the new toilet suite myself?
No. OneBookPlus Plumbing supplies the suite as part of the job. We carry close-coupled and wall-faced suites on the van. If you have a specific model you want fitted, let us know when you book and we will confirm whether we can source it.
What is a rough-in measurement and why does it matter?
The rough-in is the distance from the finished wall to the centre of the waste outlet on the floor. Most Australian homes have a 140 mm or 180 mm rough-in. If the new suite does not match your rough-in, it will not sit flush against the wall. We measure before removing the old suite so the replacement fits correctly.
My toilet is leaking at the base — does it need to be replaced or just re-sealed?
A leak at the base usually means the pan collar seal has failed. In some cases re-sealing is sufficient, but if the pan is cracked or the suite is old, replacement is often more cost-effective. We will assess the cause when we arrive and give you an honest recommendation before any work begins.
Can you replace a toilet suite in a unit or apartment?
Yes. We work in houses, units, and apartments across Sydney. For apartments we are familiar with strata requirements and will advise if any notification to the building manager is needed before isolating the water supply.
Do you replace wall-hung toilets as well as floor-mounted suites?
Floor-mounted close-coupled and wall-faced suites are our standard toilet replacement service. Wall-hung toilets with in-wall cisterns involve additional work inside the wall frame. Contact us to discuss your specific setup and we will confirm what is involved.

What Sydney Homeowners Say About Our Toilet Replacement Service

The plumber arrived on time, measured up, and had the new suite fitted and tested within two hours. He replaced the flexi hose and isolation valve without being asked, which I appreciated. The bathroom was left spotless.
Karen T.· Homeowner, Parramatta
I had a cracked pan that had been leaking at the base for weeks. OneBookPlus came out the same day, confirmed the issue, and fitted a new suite before the afternoon was out. Upfront quote, no surprises on the invoice.
David L.· Landlord, Inner West Sydney
I was worried about the rough-in measurement because the bathroom is older. The plumber measured carefully, confirmed the suite would fit before removing the old one, and the whole job went smoothly. Very professional from start to finish.
Michelle R.· Homeowner, Sutherland Shire
