Locking Mechanism On Composting Toilet
Wood Plastic Composite
The walls and roof of the Composting Toilet MKII are made out of Wood Plastic Composite (WPC). This makes the toilet resistant to extreme temperatures either high above or below zero and UV exposure increasing the buildings longevity and endurance. In place of our normal timber designs, WPC makes transportation to rural areas easier. Coming in flat pack for ease of assembly at any destination, the WPC is virtually maintenance free.

Composting Toilet Ventilation
The Composting Toilet MKII features a solar powered fan assisted ventilation pipe, which helps to remove unpleasant odours.  This fan actively draws the odour out of the structure rather than waiting for it to rise, a process called positive ventilation. The fan will continue running for approximately 15 minutes after you’ve left the structure, in similar fashion to a domestic extraction fan.

Avoid unpleasant odours
The waste deposited in the 44 litre collection tank gets sprinkled by peat from the upper tank absorbing moisture from the waste. Peat is a unique natural antiseptic and absorbent, which provides a sanitary coating for the waste, initiates the beginning of the composting process and removes unpleasant odour.

Solar Powered
Our Composting Toilets can stand independently from electricity sources due to the solar panel on the roof. This solar panel charges a 12V battery pack (not supplied) which, in turn, powers an electric water pump that feeds water through to the sink so you can wash your hands. This also powers a multi-charging point which helps to keep the phones charged.

To ensure the very best quality, we only use slow-grown White Spruce Timber, which is harvested in cold climates to ensure solid, dense log rings. This gives the wood superior strength and longevity, and also a much more consistent colour than the likes of Pine.


Despite the care we take in selecting the very best Timber available, it’s not like predictable brick or cold steel, this natural material has characteristics and quirks unique to every log.


Because our timber logs once fed water and nutrients back and forth from its roots to its leaves, its very nature is to be porous and swell up when it gets wet. Any wooden product will do this throughout its life, but there are a few things you can do to help limit this movement.


These include:

1. A great design!

  • Don’t worry, we’ve got this one covered. We’re experts when it comes to all things timber, so we have designed our products from the ground up with its natural properties in mind.

2. Water Repellent Treatment.

  • How you customise and decorate your product is up to you, however we would recommend that you use an appropriate water repellent treatment. This really helps minimise the amount of moisture that the timber can absorb. Therefore minimising the risk of any major movement.
  • (Please note: water repellent treatment is not the same as pressure treatment, which protects against rot and insect infestation, and which we guarantee for 10 Years!)

3. Ventilation.

  • Keeping your timber building ventilated is no less important than keeping your house well ventilated. This is especially true if you plan to cover up your floorboards with something (double check with an expert, that the material is suitable to do so), as moisture can become trapped between layers of non-breathable materials and build-up, leading to floors becoming rotten.

4. Regular Seasonal Maintenance.

  • Whether you opt to build your product yourself, or have us do it for you, don’t be afraid to tighten the odd bolt here and there. Your product is a life improving investment, so it’s only right to give it some love and care from time to time. Make sure that it’s properly treated before the rainy months, and you make adjustments to doors and window frames, when needed.

Please be aware that, as these are natural timber properties they are not considered as defects under our Terms & Conditions (for more information, check out our Ts&Cs here). However, in most cases, these imperfections will not impact the integrity or function of your timber product, and/or can easily be rectified.
