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.
No, the seat has been designed in such a way that this would not be necessary.
We don’t at the moment I’m afraid.
After removing the solid waste it must be composted for a further 6 months.
It is possible to use a 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.
The crank handle can be removed and you can use a 3/8″ socket wrench adaptor instead which reduces the width even further.
Most cleaners are fine eco friendly or not. Don’t use chlorine based cleaners.
The outside diameter is 1.8″ (4.57cm) The inside is 1.5″ (3.81cm). Please note that the hose has a reverse exterior thread on it.
The main body of the toilet comes with a FIVE year warranty against manufacturing defects. The fan has a one year warranty against manufacturing defects. Damage caused through misuse, poor installation and/or ‘wear and tare’ are not covered.
The exhaust/vent can be fitted to either side by the user. In the case of a building, you would usually run it out through a wall. For a camper van or other vehicle, the wall or floor are options.
The flexible urine hose that comes with the Villa and Weekend is 2 metres long. Although you can purchase extra lengths and join them, there is a risk of sagging so we recommend using rigid pipe in its place. Always make sure there is a drop of 1cm per metre to ensure adequate flow and to help prevent blockages. Where a significant portion of the urine pipe is outside, and you want to use the toilet through winter, we suggest using 40mm or 50 mm rigid pipe to the soak-away pit or drain.
For rigid pipe, products such as PolyPipe are readily available in 32mm, 40mm and 50mm diameters from DIY stores and plumbing shops. You can choose from push-fit, compression or solvent weld depending on your installation.
Because the liquids and solids are separated and are not mixed, there is never any latrine-type odour from a Separett toilet. A certain amount of odour may be present outside, around the vent exit point for a short period of time immediately after the toilet is used, but this will reduce quickly.
No. Soak-away pits don’t smell because the urine is let out under the ground and diluted with rain etc.
No. Because the fan in the Villa and Weekend runs continuously there will be no unpleasant odours in the room. Unlike other, inferior compost toilets which use narrower gauge vent pipes or poorly designed fans, the Villa and Weekend are 100% efficient at removing odours without the need for any sawdust or cover material. When installing the toilet, make sure that the venting pipe is properly sealed with silicone. The easily accessible fan filter should be cleaned regularly as well as the insect net at the end of ventilation pipe.
No! The fan on the urine diverting toilet should be the only fan in the room. It runs continuously and will circulate the air in the room and vent the moist air from any shower etc. An additional wall mounted fan may cause a small vacuum effect in the room, drawing smell from the toilet in the wrong direction.
For UK customers, the Building Regulations specify that the room the toilet is in (the WC) should have either an opening window and/or a fan – the capacity and type of fan is not specified, so the fan in the Villa will satisfy the Building Regs requirement if no opening window is present.
Yes. You will get a rain cap in the standard installation kit but it doesn’t come with any roof flashing, so you’ll have to source that elsewhere – make sure you get the appropriate type for your roof type. We would recommend trying to run the vent pipe out through the wall where possible as avoiding a hole in a roof is always a good thing, but there are times where it’s not possible.
Yes, although Separett don’t sell this. Always ensure the pipe is at least 75mm is diameter to ensure adequate air flow and low noise. Using a narrower gauge vent pipe can lead to lower efficiency and increased noise.
Can the ventilation for the Villa or Weekend be run into larger diameter vent stacks, such as 110mm?
We don’t recommend sharing the vent stack with other things. However, there’s no reason why not to use another (larger) size of ventilation pipework if you have some and can adapt from the 75mm pipe on the toilet.
Yes, you can extend the ventilation pipes and add additional bends. We sell a kit consisting of 2 pieces of 1 m pipe, 2 straight joints and wall brackets to give a 2 metre extension.
Be aware that the Villa 9010 and Weekend have slightly less powerful fans (compared to the Villa 9000), so we recommend using maximum 2 x 90° bends and 4 m ventilation pipes in total.
You can also use 75mm flexible vent pipe which is often sold for dust extraction (we don’t supply this) which might be easier to go around irregular shapes.
No, we don’t recommend using the Villa or Weekend without the fan operating. Without a fan, it starts to smell which can attract flies. With the fan is running, all odours are kept out and the solids bucket stays dry.
No. They are designed to be used without any additional cover material needed for odour control. Using cover materials can messy (bits get everywhere), is an extra and unnecessary step and will reduce the overall capacity of the solids container, leading to more frequent emptying. The Separett Villa and Weekend have been professionally designed and manufactured to make using them as simple as possible – no sawdust needed!
No. The Villa 9000/9010 and Weekend perform correctly with the room’s regular fresh air supply (windows, door gaps, etc.). Keep in mind that there should NOT be another extraction fan in the same room as the Villa or Weekend – in some circumstances the more powerful fan can cause odours to be brought out of the toilet. For UK customers, the Building Regulations specify that the room the toilet is in (the WC) should have either an opening window and/or an extractor fan – the capacity and type of fan is not specified, so the fan in the Villa and Weekend will satisfy the Building Regs requirement if no opening window is present.
For a single person using a Separett Villa or Weekend, you can expect the solids contact to last up to 8 weeks before emptying. The reason is that urine accounts for about 85% of the waste volume and is routed away from the toilet. This vastly increases the storage capacity for solids and because you don’t need to use cover material, the container lasts a long time. Removing, emptying and replacing the container takes just minutes, so there’s virtually no downtime.
The installation is reasonably straightforward for any person competent in DIY although precise times will vary depending on the tools you have available, your skills, the fabric of the building and any unusual requirements for routing the vent pipe and/or urine drain. Assuming that you are venting out directly behind the toilet, a typical installation in a building made from wood would take around 3 hours. For solid walls, there will be additional time in drilling holes through brick/concrete. Routing the vent pipe and/or urine pipe to alternative locations will entail additional work. In our webshop, there are installation videos shown against the main products.
If four people are using the toilet on a daily basis, then a container will last about 3-6 weeks, depending on how much toilet paper is being used. You can of course, empty the solids container at any time you choose – there’s no need to wait until it’s full.
Beyond regular cleaning (as you would with any toilet), a yearly or half yearly inspection is advisable. Turn the power off (to stop the fan), open the toilet and look at the mesh cover over the fan.
The cover is removable on the Villa, so take it off and brush off any debris as required. With the cover off, look inside and visually inspect the fan blades and if needed, gently brush off any debris with a soft brush. On the Weekend, use a soft brush to remove debris from the mesh cover.
If you have a Villa, check the condition of the cables that operate the concealer screen and bucket rotation. Use an appropriate lubricating oil (the type suitable for bicycle gear and brake cables) if needed to ensure the cables run smoothly and are protected from corrosion.
Yes! There are two aspects to consider, one is complying with building regulations (which deal with the day to day use of the toilet within the fabric of the building) and the other is the Environment Agency (which is concerned with the manner, method and safety of how the outputs are dealt with).
Current UK building regulations (as at 2019) permit compost toilets provided that there is a way to empty the contents without having to carry the uncomposted material through a living area (including a kitchen). Further information on the relevant building regulations is on our website [link].
The Environment Agency in England and Wales (the SEA in Scotland) permit the discharge of urine to the ground (through a leaching bed / soak-away pit) under an exception clause, provided you are at least 10 metres away from a watercourse and the discharge would be under 10 litres per day. Solid material can be composted onsite provided that the resulting compost is not used for commercial growing. Further information on composting/dealing with solids and liquids are on our website [link].
Please note that this is our interpretation of the current regulations and is given in good faith but does not represent legal advice. You should always consult the relevant official bodies to ensure you comply with any regulations.

Problems with flies are very uncommon with Separett toilets. However, flies may enter the toilet if you leave it for a week or so with the fan switched off and the container with solids still in place. If flies do get in to the toilet, change or empty the container, clean it thoroughly, and use fly spray on the toilet and container several times during the following week to remove any remaining larvae. Never add bark, coir or sawdust because it can contain larva which can develop problems with flies. Remember that flies will not enter the toilet through the ventilation pipe as mesh barriers are in place.
No! Both the Villa and the Weekend are designed to be completely odour free in day to day operation. If you detect any bad smells in or around the toilet, firstly check that the fan is operating correctly and that there are no obstructions where the vent comes out of the building.
The most common reason people get foul smells is where you are have been sharing the soak-away pit for urine with other grey water (such as sinks, baths and showers). It’s best to have a small, dedicated soak-away pit for the urine from toilet, but where this is not possible, and smells are detected, the solution is to fit an in-line trap to the urine pipe.
If you are using standard rigid pipework, look at products such as the HepVO inline trap.
Yes. The toilet is designed to have the fan running whenever there is anything in the solids bucket. Running continuously keeps moisture levels under control and extends the lifetime of the fan. If the fan has to be switched off, place the lid on the container and remove it. Otherwise, bad odours may spread indoors and flies have a chance to enter and lay eggs.
In most cases, no. The faint odour that may come from the urine hose is drawn out through the vent pipe due to the action of the fan. A water seal is only needed if a strong odour from the greywater system would be noticed inside or outside the house.
If needed, we sell a Separett in-line trap for the urine pipe.
If you are using standard rigid pipework, look at products such as the HepVO inline trap.
Yes! We have a range of spares in stock in our UK warehouse and have access to a complete range of spares and replacement parts from Separett in Sweden. Get in contact and let us know either what you need and what the problem is and we can the appropriate parts sorted for you.
If the screen has broken due to pressure being applied, a replacement is available through our website.
If the toilet is older, a service kit is available that includes the screen and the actuator cables for the screen and solids bucket rotation system.

Normally, urine flows away quickly (within seconds). If you’re experiencing any problems, check the following:
Is the urine pipe installed correctly? Does the urine pipe outside the toilet have sufficient slope? We recommend a slope of about 1 cm per metre.
Check whether the collection container, soak-away pit or infiltration bed is not full or fouled in some way.
Over time, there is a risk that as urine drains it coats the inside of pipes with salts and minerals. The Separett Cleaning Kit for urine separating toilets is supplied with a product that is ideal for solving these issues. We also recommend using the Separett Bio-Drain tablets which are placed in the urine bowl and will help prevent the build up.
Commercial drain unblocking products can be used, but with caution, and only when standard cleaning etc has not worked.
In the worst case you may need to replace the urine drain pipework to remedy the error. The internal pipework on the Villa can be purchased as a spare part.
With the Separett Ejektortank, approximately 1 litre of urine is mixed with 8 litres of fresh water automatically as you use it. This may result in a faint odour, but it will soon disappear. You can speed the process by adding more water or spreading the mixture at night or when it rains.
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.
The frame is made from galvanised steel and the fixings are stainless.
No, our products cannot be hired due to them being a semi-permanent installation, the system is installed in the ground.
No because the manufacturer does not sell them separately.
Yes, 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 the strong (often 130 km/h) winds very 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.
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.
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.
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:
- 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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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”.
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.
