Yes. A toilet that doesn’t need conventional plumbing is usually a waterless composting toilet or a portable toilet. It can work without a flush-water supply and may not need a sewer connection, but permanent models can still require ventilation, liquid drainage, electricity, servicing access or an underfloor chamber.
Options without conventional plumbing
- Waterless or dry toilet: Collects waste without using flush water. Requirements vary by design.
- Composting toilet: Uses a controlled decomposition system. It may be self-contained or connected to a chamber below the floor, and some models separate liquids.
- Self-contained toilet: Houses its storage or treatment chamber within the unit. Ventilation, power and emptying requirements depend on the model.
- Portable toilet: Stores waste for collection by a servicing provider. It suits temporary uses such as worksites and events.
These toilets handle toilet waste only. Water from basins, showers and other fixtures still needs an appropriate wastewater system. If you prefer a conventional flushing toilet, check whether a toilet can be added where there is no existing plumbing.
What might installation require?
Check the manufacturer’s specifications before choosing a unit. Depending on the model and site, a waterless toilet may need:
- a vent, sometimes with an electric fan
- a liquid drain or separate collection container
- electricity
- space above or below the floor
- safe access for emptying and servicing
- scheduled waste collection.
A conventional alternative will need water and sanitary drainage. Its WELS rating can help compare water-efficient toilets once the site requirements are known.
For a permanent Sydney installation, check approval and wastewater requirements with the relevant local council before buying. Plumbing a new toilet in NSW is not a DIY task; use an appropriately licensed plumber. Sydney Water should also be consulted where the proposal affects its water or wastewater services.
Hygiene warning: Human waste can contain harmful pathogens. Do not improvise disposal or service a unit contrary to its instructions. Follow the manufacturer’s hygiene requirements and use an authorised waste contractor where required.
A permanent composting or self-contained toilet may suit an approved long-term installation; a serviced portable toilet is generally simpler for temporary use. Contact our licensed toilet installation plumbers to assess the site and identify any plumbing requirements before purchase.
