FAQs about toilet installation
Do I need a licensed plumber to install a toilet in Australia?
Yes. Every state and territory requires a licensed plumber for toilet installation. It isn’t a DIY job — a bad install can let sewer gas into the home, which is a health hazard, and cause water damage when connections fail.
How long does toilet installation take?
A standard like-for-like replacement takes 45–90 minutes. A wall-hung toilet with an in-wall cistern takes three to five hours depending on the wall type.
Can I supply my own toilet?
Absolutely, we’re happy to install one you’ve bought. Just confirm the rough-in measurement, the trap type (P-trap or S-trap) and the pan collar dimensions before you buy, so it matches your existing floor fitting.
