Frequently Asked Questions


+ Can young children use the loos?

The loo is very similar to a standard toilet. The difference being that there is no flush and instead of a ubend with water there is a hole. The size of the hole, (the top of the bowl), is roughly the size and shape of your average loo seat so children that are comfortable using a regular toilet are fine to use our loos.

Incase of accidental locking of the cabins, each one can be unlocked from the outside.

+ Are the fixings on the KL2 stainless?

The frame is made from galvanised steel and the fixings are stainless.

+ Why use a waterless toilet?

For a variety of reasons; if the installation in mind is far from a water source or in an area of low supply, or you simply wish to consume less, the answer is self evident. In a self contained, exterior installation, a waterless toilet will almost certainly be less expensive to install, considering the cost of bringing water to the site and hooking up to the waste water network. In an internal, mixed environment, (e.g., where water is available and used for sinks), waterless toilets can greatly simplify the treatment of the waste water. In all cases, due to the fact that waste is treated on site, a waterless toilet will typically impose less strain on environmental resources.

+ Can the cabins withstand 100mph winds?

We recommend you purchase the KL2 for extremely windy conditions. It has no corners or big, flat, vertical surfaces and they have lot installed in extreme conditions in France situated in the Mistral and they resist quite well. They have a concrete base which stops them lifting off the ground. The door also can't be blown open as it's curved.

+ Why do waterless toilets not smell?

The key is the separation of the liquids and solids and the airflow. By separating the waste in side the Kazubaloo System and ensuring that a near continuous flow of air passes over the separated waste the system is designed to ensure that decomposition is an aerobic process. The products of aerobic decomposition are odourless and non-toxic.

Miranda Campbell, Environmental Practices Adviser at the National Trust said: "We had been most worried about the potential for the toilet to smell, but we have had the loo a year now and smell has never been an issue".

+ What kind of lock is on the KL2 and can it be changed?

The lock is a standard euro cylinder and can be easily changed. You can personalise your lock if you can produce a euro cylinder to match your key.

+ What happens to the waste material when it's cleaned out of the toilet?

The dried waste is removed from the toilet in a basket, having spent roughly a year in the system drying out. The inert and odourless dry waste is transferred in the baskets, using the precaution of gloves, into a secondary composting process to allow the waste to be composted fully. This generally takes the form of a compost bin dedicated to the waste. This bin will, over time, produce compost which should only be used on non-edible vegetation. However, the reality is, that the compost bin will fill up very slowly and therefore will not need emptying for a considerable time.

+ Why can't I just use a traditional composting toilet?

You can! However, composting toilets need more care than a dehydrating, evaporating toilet, and will typically require you to deal with larger amounts of waste material and usually have a higher frequency of maintenance.

+ What if there's no sun or wind?

A waterless toilet provides advantageous conditions for evaporation and it is extremely rare that zero evaporation will occur. In any event, if there is waste in the system, then microbiological activity will continue and the waste will continue to break down. If a period of prolonged darkness and lack of wind occurred and waste was continually added to the system, then this would present a problem, but it's somewhat unlikely.

+ Do they work in cold wet climates?

Waterless toilets do work in cold wet climates, the amount of usage a toilet gets should be matched to the climate. In colder climates the toilets should be used less and in warmer climates the usage can be increased.

+ How many uses per day can the toilet accept?

The short answer is, as many or as few as required. The long answer is that depending on the climate, the immediate surroundings and the pattern of usage, a higher or lower frequency of maintenance will be required. Under average conditions, frequency of maintenance might be once or twice a year, under extremely high usage, this might be bi-monthly.

+ What about toilet paper?

This will break down alongside the human waste. Disposing large amounts of triple ply paper into the Kazubaloo is not advised - the system will become a large paper bin eventually - but it will not hinder it's operation.

+ How is the toilet bowl cleaned?

We recommend using Ecover spray cleaner, or equivalent, and a brush. If you need something more abrasive, gardeners lime seems to work well for other customers. Toilet paper varieties make no difference, ethically it might be preferable to go for a recycled brand. It is important to avoid using large amounts of water as this will simply be added to the liquids already in the system waiting to be evaporated.

+ What happens if people throw rubbish into the toilet?

Nothing. The Kazubaloo will continue to function as normal in spite of drinks cans, sanitary towels, plastic cutlery, nappies and so on being thrown into the system. They will be retrieved at the end of the cycle and disposed of in the normal way. It is sensible to provide a sanitary bin for the disposal of these items.

+ Can I fit a Kazubaloo in my house?

No because the manufacturer does not sell them separately.

+ How often does waste need to be removed?

It is recommended that the system is inspected regularly during the first few months of operation to assess the level of use. Following this period, you will be able to estimate the number of times a year it must be maintained, usually once or twice. As a rough guide, if by looking in the toilet bowl you can make out the top of the pile of waste below - not usually possible under normal conditions - then it is time to service the loo.

+ It's pretty unpleasant, doing maintenance, right?

Yes and no. If the unit is not overused, then this is a 5 minute procedure, which will not bring you into direct contact with human waste. If the unit has been overused and you arrive to find that the maintenance is overdue, then the basket at the front of the system will be more full than it should be and it will be more difficult to swap the baskets. You will not come into direct contact with the waste, but some people might find the idea of this operation unpleasant. (Sort of like changing the nappies of someone else's baby). Please click here to reference the maintenance guide for further details.

+ What is the guarantee?

The Kazuba guarantee covers the unit against production faults and is valid for 24 months. It does not cover damage occurred due to faulty installation.

+ Whats best solution for disabled access?

The KL2 and KL3 can both be configured to be fully compliant with Part M of the building regulations. The KL2 always comes fully accessible and the KL3 will require additional hand rails to be fitted. If your scheme requires this, let us know and we will factor it into the installation estimate.

+ How many litres can the loos hold?

The tank holds around 400 litres below the dry plate that the solid waste baskets sit on. Unfortunately rates of evaporation are very hard to predict as they depend on the local climate. Therefore there is not a direct correlation from volume to usage limits.

+ How much do the loos weight?

Weights of Kazubaloos: KL1 180kg KL2-pmr 360kg

+ Are your loos for hire?

No, our products cannot be hired due to them being a semi-permanent installation, the system is installed in the ground.

+ Does the waste need to be further composted in a composting heap after removal?

The dried waste is removed from the toilet in a basket, having spent roughly two years in the system drying out. The inert and odourless dry waste is transferred in the baskets, using the precaution of gloves, into a secondary composting process to allow the waste to be composted fully. This generally takes the form of a compost bin dedicated to the waste. This bin will, over time, produce compost which should only be used on non-edible vegetation. However, the reality is, that the compost bin will fill up very slowly and therefore will not need emptying for a considerable time.

+ How long till I receive a toilet?

We require a 50% to confirm the order. Once this has been received we'll then place the order for the loo with our suppliers. You should then receive your order between 4 - 6 weeks time.

+ Are the cabins secure?

Both the KL2 and KL3 cabins come with an lock incorporated into the door, and the come supplied with spare keys. The KL1 is not supplied with an incorporated lock.

A hasp lock can be fitted to any of our models which can then be locked with a lock of your choice. For example some of our customers have fitted a combination padlock. If you want a hasp and staple fitted when your toilet is installed then you should let us know and it can be arranged.

+ Do we have to treat the woodwork?

In terms of treating the cabin wood, the cladding doesn't strictly need to be treated as it's been through an intensive heat treatment which stops it from moving with weathering but sunlight will weather it's appearance a little and make it look greyer. If you want to keep the color in the wood then you can treat it with an oil based substance.

Here's a paragraph from the wood manufacturers guide:

  1. Surface treatment To prevent colour changes and other natural effects of weathering it is recommended that surface treatment is used. Oil-based substances work well and in a similar way as with untreated wood. When working with water-solvent substances it has to be taken into account that ThermoWood has a lower water absorption rate than normal wood, this can have an effect on drying time and penetration. Results are also dependent on the paint application and drying process. The paint manufacturer’s instructions should be followed.

In conclusion adding of a layer of creosote on the outside doesn't hurt.


Air Head

+ Which side of the boat can the vent/exhaust be fitted?

The exhaust/vent can be fitted to either side by the user.

+ Do you provide wooden seats?

We don't at the moment I'm afraid.

+ What is the diameter of the Hose?

The outside diameter is 1.8" (4.57cm) The inside is 1.5" (3.81cm)

+ Can I use a solar vent with the Air Head?

A better and cheaper option is a solar panel, 10 watt minimum in UK.

Other options are Nicro Day/Night Solar Vent, where the AirHead fan is integrated with a switch and used only occasionally. We do not recommend use of any solar vent exclusively as all will at some point stop due to limited battery capacity. This may result in flying insects finding their way into the system by detecting the toilet itself. Do not remove fan screen, this screen is very necessary. A solar panel, (minimum 10 watt), may be added to counter effect the battery drain caused by the AirHead fan.

+ Is there anything smaller than the crank handle?

The crank handle can be removed and you can use a 3/8" socket wrench instead which reduces the width even further.

+ I have only a 240V supply how can I use the 12V fan?

It is possible to use a standard 12V power supply rated at 1000ma (1amp). You can then cut the connector off at the end and attach it to the fan end cables.

+ What cleaning products can i use on my Air Head?

Most cleaners are fine eco friendly or not. Don't use chlorine based cleaners.

+ How long before the solid waste can be used?

After removing the solid waste it must be composted for a further 6 months.

+ Do children need a child adaptor seat?

No, the seat has been designed in such a way that this would not be necessary.
