To remove an old toilet, isolate the water, drain the cistern and pan, then have a licensed plumber disconnect the water supply and sanitary waste connection. Release the cistern, fixings and sealant as appropriate, lift the pan upright and immediately cap the waste opening. Confirm the disposal option with the installer, council or receiving facility before work starts.
Prepare and drain the toilet
Clear the area, protect the floor and locate the toilet’s isolation valve. Wear gloves and eye protection, and keep towels, a bucket and a sponge nearby. Do not use drain-cleaning chemicals beforehand.
Turn off the isolation valve, flush the toilet and hold the control down to empty the cistern. Sponge the remaining water from the cistern and pan into a suitable container. If the valve leaks or the cistern keeps filling, stop and call a licensed plumber. Do not repair or disturb the valve yourself.
Identify whether the toilet has a close-coupled, separate or concealed cistern. Wall-hung and concealed systems have model-specific connections that should not be forced open. Before buying a replacement, check how toilet set-outs and trap types affect compatibility with the existing waste connection.
Remove the toilet in this order
- Confirm isolation: Check that the cistern has stopped refilling and remove as much residual water as practical.
- Disconnect the supply: A licensed plumber should disconnect the toilet water supply line and catch any retained water.
- Remove the cistern where appropriate: Separating a close-coupled cistern can make the pan safer to lift. Concealed systems require the correct access procedure.
- Release the fixings: Remove accessible toilet fixing bolts and cut removable sealant around the toilet base without damaging tiles or waterproofing. Leave hidden, corroded or cemented fixings to a plumber.
- Disconnect the pan: A licensed plumber releases the toilet pan from its sanitary waste connection without twisting or levering against brittle pipework.
- Cap the waste: The plumber should immediately fit a secure temporary cap or plug suitable for the pipe. Do not use a loose rag, which can fall into the drain.
- Lift the toilet: Keep the pan upright and place it on protected material. Toilet pans are heavy and may contain contaminated water, so use two people or suitable lifting equipment.
In NSW, disconnecting a toilet’s water supply or sanitary waste connection is plumbing work that should be completed by an appropriately licensed plumber. Homeowners can safely clear the area, operate a working isolation valve, drain the fixture and help with lifting after disconnection.
Dispose of the old toilet
Ask whether the plumber or toilet retailer offers removal. Otherwise, check the current rules for your local council clean-up service or a licensed waste facility, as acceptance and preparation requirements vary. Do not place the pan in a household recycling bin or leave it on the kerb without an approved collection.
Keep the toilet upright during transport, contain residual water and protect it from breakage. Vitreous china is heavy and broken edges are extremely sharp. Do not smash the pan to make it fit a bin or vehicle.
Avoid wastewater contact, cover cuts and wash thoroughly afterwards. Stop if the toilet will not release, appears cemented in place or has concealed connections. Our Sydney toilet-replacement plumbers can handle the regulated disconnections, safely cap the waste opening and advise on removal of the old fixture.
