Congratulations!
You are the proud owner of a Nature's Head® separating toilet. Here are our instructions on how to install your composting toilet in your motorhome, camper, boat, garden shed or any other place.
Check that everything you ordered and all installation materials are included.
Your Nature's Head® separating toilet comes with all the necessary components for installation. You should also consider the following:
Your composting toilet already has a fan pre-installed that will remove moisture from the container. The exhaust air should be directed outside. If you already have an older ventilation opening, you can use gill plates in various sizes to cover it.
For some installation variants you might need a longer exhaust air hose. In this case, you can work with HT40 (40 mm) PVC pipe. Remember that the end of the pipework must be flexible and removable so that you can remove it to empty the solids bin of your composting toilet.
The screws included in the installation kit are only suitable for wooden floors. If you want to install your toilet on concrete or similar surfaces, we recommend mounting it on a (painted) wooden plate, which can then be screwed or glued to the concrete.
If you want to operate the fan via a normal 230 V connection (household socket), you need a suitable power supply unit. This transforms the 230 V of your household connection to 12 V, you can find some with German plug in our shop.
All composting toilets need an absorbent substrate so that the process can be odour-free. We recommend coconut fibre, an environmentally friendly and sustainable waste product from the production of coconut fibre ropes. The fibres are pressed into bricks, which are light, small, easy to store and transport. You can find the right bricks at the Shop / Composting toilet accessories.
If you have very little space at the installation site, you can also carry out the necessary maintenance work by detaching the toilet from the floor and moving it slightly.
Once you have chosen a suitable place for your toilet, you need to fix it to the floor of your boat, motorhome or summer house. To do this, you will need the two mounting brackets supplied.
Usually, the mounting brackets are fitted in the recesses under the toilet (see manual). Retractable screws for installation on a wooden floor are included in the mounting set.
Before drilling holes in the floor, make sure that there are no cables or similar underneath. Take special care not to drill into the hull in a boat!
Your composting toilet needs to be vented to the outside, whether it is a boat, a mobile home or a garden shed. Ventilation removes odours during use and any moisture that develops, and encourages the growth of beneficial bacteria involved in the composting process.
It's a simple system. On one side, the fan draws air out of the toilet to an opening on the outside. At the same time, fresh air flows in on the opposite side of the toilet.
The installation of the ventilation is the most difficult part of a composting toilet installation. Depending on the placement of your toilet, you may need to drill or cut holes in the wall, ceiling or floor. With the right tools, this should not be a problem. If you're not sure whether your DIY skills are sufficient or you're missing tools, get help from a tradesman or check out our installation partners across Europe.
A simple 12 V computer fan that requires less than 1.2 Ah per 24 hours is the only part of the toilet that needs electricity. A suitable low-voltage plug (5.5 mm x 2.5 mm) with a cable approx. 45 cm long is included in the installation kit. It is plugged into the socket on the fan housing.
As with all electrical installations, make sure that the fan is only operated in a protected circuit. The fuse should be at least 2 A and a maximum of 5 A at 12 V. A fuse and a fuse holder for operation in unprotected 12 V systems, e.g. with direct connection to a battery, are also included in the installation kit.
Of course, you can also operate the fan on a 230 V power source, you will need a suitable plug-in power supply unit for this, which you can obtain (German plug only!) in our shop.
If you are not sure about the electrical installation, please contact an electrician.
If the installation of the ventilation on one side of your toilet is better than on the other side, you can always exchange the fan housing with the filter housing on the other side.
When the toilet is delivered, the crank handle is not yet mounted. It must be attached first. The standard crank handle (no longer available) is fastened with a metal sleeve and a cotter pin, the spider handle / foot spider handle with a hexagon socket screw.
If you want to mount the crank handle on the opposite side of the toilet, first take out the shaft, turn it around and put it back in.
Composting toilets are perfect wherever you need a sanitation solution but there are no supply or waste water pipes.
