Due to customer demand, our Ultimate pedestal is now available as a self-contained unit.
The self-contained version of the Ultimate utilises an internal container for collection of solids, and includes automatic urine diversion and active ventilation along with the other features of the Ultimate pedestal.
The Ultimate SC is suitable for minor use in sheds, camps, mobile homes or other temporary situations. Underfloor access is not required, as the urine hose connects to the rear of the unit.
The Ultimate pedestal diverts urine away from the composting chamber, allowing you to pipe or bottle it for use as a fertiliser.
Urine diversion significantly enhances a composting toilet system:
- speeds up the composting process
- minimises required storage
- significantly reduces odour
The Ultimate pedestal has been extensively tested and modified through many iterations, resulting in a bowl design which effectively and automatically separates urine flow. Simply connect a hose to the fitting on the rear of the pedestal and direct it to a dissipation trench or storage vessel.
Urine is sterile (provided you are healthy) and for gardeners, it can be an excellent fertiliser as it is very rich in phosphates.
The 11 litre container is not designed to be a primary composting chamber. Due to its size, it may not generate enough heat and composting may not proceed entirely.
We recommend emptying it regularly into an external composter where ideal composting conditions can be managed and the waste can be allowed to break down for a longer interval.

Will it be approved by my local council?
We've summarised the local government approval process in NSW for your information.
How does the vanity shutter work?
Simply press down on the knob and rotate to swing open or close the shutter. It is manually-operated, and customers wishing to leave it open may do so (although it is best to close it after use).
Is the double-bowl urine diverter suitable for females?
Absolutely! The urine diversion system has been designed for women and men to use comfortably.
What do I do with the diverted urine?
Connect a 25 mm diameter hose to the urine port and run it to a small trench (e.g. two metres long). Plant some lemon trees and open a lemonade stand! Alternatively, some people bottle the urine and mature it for use as a fertiliser.
What customisation options are available?
The Ultimate SC can be modified for a range of situations. The ventilation and urine ports are at the rear of the unit, but can be altered on request. Spare 11 litre containers are available at hardware stores, and altering the design of the floor allows larger containers to fit.
General composting toilet questions
How much waste is produced?
The average human produces 125 g of solid waste per day. In a four-person household, that's half a litre every day, continually breaking down as it decomposes.
Will it smell?
If the variables of the system are managed correctly (heat, water content, bulky additives to prevent compaction) then no, the compost will not smell. The pedestal's ventilation fan will further assist to keep the room air fresh.
How long does the composting process take?
It depends on those variables (primarily temperature), but anything from weeks to months. Finished compost is like humus, a dry earth-like substance that is rich in nutrients.
What can be added to compost?
All organics are fine to add, from vegetables to garden waste. Just make sure the compost doesn't get too wet, too dry, or too compacted. Some people add worms, a process called vermicomposting.
How can I use it when it's finished?
There's a lot of information out there on which plants are most suitable to fertilisation by compost but all areas of your garden will benefit, although you may not wish to use it for growing food.
Is it really safe?
Yes. It is recognised by the World Health Organisation as a viable method of managing human waste. If the conditions are right, the composting process will eliminate the pathogens in your waste. In an absolute-worst-case scenario, if your compost is only for personal use: you could only catch something you already had.
