Need a compost toilet?
Look no further!

From single cubicles to wheelchair accessible units, we make a variety of lovely Thunderbox Compost Toilets to order and can deliver to anywhere in the UK. Our system is compliant with the Environment Agency’s code of conduct for compost toilets so you have the assurance that a Thunderbox is safe to use and free of nasty odours. Thunderboxes are probably the most sustainable compost toilets available and use a virtually maintenance free system that is ideal for a wide variety of situations.

Sustainable

We have always had a strong environmental ethos and view sustainability as a priority. We use organically certificated timber, sourced from sustainably managed Devon woodlands and collect compost in recycled food containers.

No Water or Electric

Thunderbox Compost Toilets are entirely off-grid, requiring no water or electricity. We can include solar lighting, and provide hand sanitiser dispensers for waterless locations.

Event Hire

From small events and festivals to weddings and other gatherings, Thunderbox Compost Toilets provide a carbon-friendly solution that is pleasant to use. Short term provision in Devon and Somerset only – sorry.

Environment Agency Approved

Unlike some other budget options on the market, Thunderbox Compost Toilets comply with the Environment Agency’s code of conduct for compost toilets so you can assure your insurers that our system is a safe one.

Pleasant to use, low maintenance, and makes great compost!

Creator of quality timber toilets with a strong environmental ethos

We all have an obligation to the planet that sustains us not to use more resources than we really need in order to survive. Thunderboxes are the perfect solution for those who take their carbon footprint seriously.

For event organisers

Generally, the hire of a double Thunderbox Compost Toilet works out around £395 without servicing, but includes delivery (within 30 miles), installation and everything needed to make using a Thunderbox a pleasant experience. We will take all the solid waste away but take ‘poo miles’ seriously, so we don’t travel more than 60 miles from our base in mid Devon for event hire. All our loos come with lighting, sawdust, loo roll, magazines, flowers and LOVE!

Legal Recognition At Last!

Environment Agency Approved

We’ve been building Thunderbox Compost Toilets since 2003 and so we have considerable experience in all scales of events and sites. We have also been working with the Environment Agency over the last few years to develop the new code on composting human waste, based on the Thunderbox method. We hold risk assessments and safety records as well as special excemption licences for some of our clients. It is important to talk to us early in proceedings to allow time for the paper trail to catch up with our bacteria!

The Thunderbox Collective have provided an excellent service to us over
a number of years. We have been extremely happy with the efficiency
with which they have set up and taken down the units supplied and we
were considered the price they charge very reasonable. We have no
hesitation in recommending them.

We now have 3 thunderboxes, a single, a double and a disabled one. The installations went smoothly and the toilets themselves have made a real difference to our facilities. The wooden structures fit well into our woodland environment, they are low impact, low maintenance and perfect for our needs.

Our team absolutely LOVE the Thunderbox and think it is a fantastic addition to the grounds. They think it is high quality, beautifully made, well designed and looks great. A minimum amount of individual parts with pre-assembled sections, clear instructions with pictures and includes screws and fittings.
Brilliant communication and advice - you have always been incredibly helpful and given fantastic guidance.
