The Air Head Compact compost toilet is one of the most simple and efficient dry lavatories of its kind. With a 12-volt fan used to dry out solid waste, and ingenious urine separating design, it also eliminates odours immediately from the living environment. Designed with the comfort of female users in mind, it is one of the easiest to use dry compost toilets available.

This Compact version has slightly less seat depth, enabling the toilet to be fixed up very close against the wall – ideal where space is very tight. The Hull version has a cut-away at the back of the lower part – useful where the wall slopes inwards or where there are other obstructions at floor level.

Please note that the ‘hull’ variant is a special order product and is only available on back-order. Please contact us for an estimate of the delivery time.


The Air Head Compact compost toilet has all the benefits of the standard Air Head but has a compact seat that enables the toilet to be installed closer to the wall behind the toilet, saving a few precious cm of space and enabling installation. Like the Air Head standard, it’s a urine-diverting toilet, enabling liquids to flow to the front (and ultimately into the urine bottle) and solids to collect in the base.

What’s the difference between the Air Head STANDARD and Air Head COMPACT?

The Air Head COMPACT version has the seat brackets/hinges at the back of the toilet pan repositioned so that the toilet fits flush against the back wall, this reduces the depth of the toilet seat slightly. In every other respect the COMPACT is the same as the standard Air Head

The HULL version has a small cut-out section at the lower back which enables it to fit around obstructions or sloping walls. Please note that the hull version is a special order product. For details of the standard/household version, click here.

How does the Air Head compost toilet work?

There’s a small, manually operated hatch that opens the solids container, which you can open once you have sat down. All you have to do is sit down and ‘go’. Urine automatically flows to the front of the toilet, where it drains into an easily and quickly removable container. Solids drop through and after your visit, you turn the handle on the side to mix your deposit with the existing contents and the coir (which is added when you commission the toilet).

Optionally, you can place a paper liner in the bowl and allow it to ‘flush’ down but opening the solids hatch. Gentlemen can also stand to urinate with the Air Head as the solids hatch will direct urine back to the front and into the urine bottle.

Does it smell?

One of the main concerns of those using compost toilets is the potential smell. With the Air Head Composting Toilet, odour-free use is achieved through several key parts – firstly urine-separation (so the solids remain dry, relatively speaking), the use of coconut coir (or similar) as a medium into which the solids fall, the turning/mixing handle (which breaks up solids mixes them into the medium), and the active ventilation system – a 12-volt fan draws any remaining odours out and assists in the drying of the solid matter.

The fan is located in a housing at the point where the flexible vent pipe exits the room. The fan draws air through a screened opening on the toilet, across the top of the solids area and through the flexible vent hose and then outside. You have the choice of either a straight or angled fan housing – the diagram below will help you decide on the most suitable version, although you are welcome to call us for advice. Approximately 1.5 metres (5 feet) of flexible vent pipe comes with the Air Head and further lengths, if needed, are available online.

The 12v fan will need wiring into your 12v electrical system and draws approximately 2 watts or 0.17A.

Another major advantage of the Air head Compost Toilet is its female friendly design. With many other urine separating toilets, it becomes something of a trial to ensure that liquids are processed through the pipe that leads to the liquid waste tank. Due to the design of the Air Head’s automatic separating system, this is no longer an issue. Even if urine does escape into the solid waste tank, the drying system negates any contamination relating to composting.

How often will it need emptying?

Depending on use, the 7.5 litre urine container will fill up quite quickly, so we would suggest daily emptying where possible. Urine is normally sterile and can be emptied directly onto earth or around trees (avoid repeatedly emptying at the same spot). Do not empty urine into the canals or rivers in the UK, as the nitrogen content acts as a food for algae. Where the Air Head is used at sea, it is usually permissible to empty urine overboard.

The time taken to fill the solids tank will vary with use. The original design concept for the Air Head was that the toilet was for boats that had mainly weekend use, and in that context, the solids tank would last a season. With more regular/frequent use, the solids tank will need to be emptied more often, perhaps every 3 to 4 weeks.

To understand the different versions (standard & marine) and the fan housing options, look at our Air Head Dimensions page.

  1. Marcus Greatwood

    It’s absolutely brilliant – can’t fault it! It has no smell, it’s easy to use and you don’t have to empty it for ages. It separates the waste perfectly and overall it’s very solid. Awesome product, very good. You accidentally sent us an extra toilet but you quickly picked it up and sent me five coir bricks to make up for the inconvenience.

  2. Tom Taylor

    It’s pretty good. it does what it advertises and performs well. It’s well designed.

  3. Ben

    I haven’t used it at sea yet but it seems to be working well.

  4. Jim

    Generally works really well. The only thing that would improve it is if you could see how full the liquid container is. Other than that my feedback is wholly positive.
