WooWoo GT LUX Porcelain Pedestal Composting Toilet – Starter Pack

SKU WWGTLUX Categories , Tag


The WooWoo GT LUX is a low-maintenance batch composting toilet system that comes with a porcelain pedestal for that ‘at home’ feeling. Ideal for campsites, glamping locations, forest schools, allotments and community gardens, as well as domestic dwellings.


The WooWoo GT LUX Starter Pack is available either with 2 x 120-litre or 2 x 330-litre composting containers, and comes with a porcelain drop-through toilet pedestal for the ultimate in ‘at-home’ luxury and durability with a full composting toilet!

The GT LUX means you can have a full composting toilet without water or sewerage connections. Composting takes place within the WooWoo GT container so when it comes time to empty, you are only ever handling compost. Residual odours are removed with either the non-electric wind fan (for installations in out-buildings etc) or the electric fan (for installations within the fabric of a dwelling).

The WooWoo GT LUX is what’s known as a split system, where the toilet pedestal is in the building and the composting container is directly under it. You will need a minimum of 800-1000mm clearance (depending on the model) under the floor for access to the composting container.

Because it doesn’t use a urine separator, it’s easy for people to use with minimal instructions, and cleaning is simple and straightforward.

Each of the containers has a unique capillary base that regulates moisture content in the solids mass above, ensuring perfect conditions for efficient composting. With two containers in the starter kit, one can be ‘in use’ whilst the other is ‘composting’ the contents. Additional containers can be purchased to increase the capacity as needed.

How does the WooWoo GT Lux work?

The WooWoo GT LUX is a composting toilet system that catches all the solid and liquid matter (no need to use a urine separator), making it incredibly simple and foolproof to use and ideal for locations that have multiple or public users.

The unique capillary base allows some of the excess liquids to be absorbed back to the composting mass, just like underwatering flower pots. This unique self-regulating feature of the WooWoo GT LUX speeds up the composting process significantly – efficient composting requires that the mass inside the container is neither too wet nor too dry. Excess ‘seep’ liquid runs out either into a container (for periodic emptying) or into a small soakaway pit.

When the first container is full, it is moved out and replaced with an empty one. The full container has a different lid put on and the contents are left to complete the composting process (which will have already started). After a suitable period of time, the contents can be emptied and left to mature for a while longer, eventually to be used as a mulch around trees and bushes. Alternatively, the contents can be emptied out at any time and transferred to another compost bin/area if you want to return one of the containers back to service before the contents are fully composted.

The capillary base, together with the efficient ventilation system, means the WooWoo GT LUX is odourless, pleasant and simple to use, making it ideal as a communal toilet on a campsite, glamping site, forest school, community garden or allotment, or even in a remote dwelling.

Doesn’t it smell?

No. The unique features of the WooWoo GT LUX, such as the capillary base, ensure that the contents don’t get saturated so efficient composting can take place. Added to this, the active ventilation system draws odours out of the container and assists in evaporating moisture.

You can choose from the wind-powered fan for completely off-grid installations or the mains electric fan. When installing the WooWoo GT LUX within the fabric of a dwelling, or where the ventilation pipe cannot be routed vertically, we suggest the mains-powered fan for absolute odour removal. If you choose the ‘no fan’ option, you MUST provide some form of assisted ventilation to remove odours.

How to use the WooWoo GT LUX

For the user, the WooWoo GT LUX is simple to use – they just ‘go’ as they would with any other toilet – there’s no requirement for men to sit down as it doesn’t rely on the separation of liquids and solids at the point of use. After every solid use, the user adds a scoop of cover material (like fine wood shavings or sawdust from chainsawing). That’s all there is to do!

Alternatively, the operator can add some cover material (wood shavings or sawdust) at the end of each day instead of the user being required to.

How to maintain the WooWoo GT LUX

For the owner/operator, the WooWoo GT LUX is a low-maintenance solution for providing an off-grid, waterless toilet facility. If you run the seep/leachate into a soak-away pit, all you need to do is occasionally inspect how full the main composting container is. If the seep/leachate is collected, then that container will need to be checked every week and emptied accordingly.

When the WooWoo GT LUX container is full, swapping to a new container should only take a few minutes. Slide the full container from the building by first detaching the flexible part of the vent pipe and the leachate tube. Depending on the building configuration, the ‘chute’ that connects the toilet seat to the container will need to be released.

Now you can pull the container backwards and out. Depending on the operator, the GT 120 can usually be moved by one person, although the GT 330 will need two people.

What’s the capacity of the WooWoo GT LUX?

The actual capacity depends on a number of factors including ambient temperature and wind speeds (as these have an effect on moisture evaporation rates), however with the WooWoo GT LUX 120, you should expect around 250 solid uses per container and with the GT LUX 330, expect around 800 solid uses per container. The amount of urine does not have a significant impact on overall capacity as any excess liquid will come out as leachate or be re-absorbed into the composting mass.

Capacity will be reduced in winter due to slowing of the composting process, lower ambient temperature and lower evaporation rates.

Extending the capacity

If you need additional capacity, you can purchase extra containers with composting lids from our website, as and when needed.

When you remove a container from use, it will have already started the composting process (this typically gets underway when the container is around one-quarter full). We generally recommend the container sits to compost for at least six months beforebeing emptied. If you need or wish to empty the container sooner, the contents should be transferred to another container to complete the composting process and to ensure they are completely safe.

Will it fit?

The GT Lux requires the pedestal to be directly over the GT container. You will need to consider the height, width and depth of the container, plus the minimum distance to under the floor (to enable servicing access to the container).

WooWoo GT LUX height diagram

For the WooWoo GT 120 LUX, the container is 700mm x 600mm x 600mm (height, width, depth). It will require a minimum clearance of 800mm to the underside of the floor.

For the WooWoo GT 330 LUX, the container is 920mm x 660mm x 820mm (height, width, depth). It will require a minimum clearance of 1000mm to the underside of the floor.

Ventilation pipe is Ø110mm. The flexible connection pipe approx. 50cm length.

Leachate hose is Ø32mm, approx. 1.5m length.
