Eco-Loo compost toilets in 3 colours

The story of Eco-Loo


About me

In 2012, I (Martin) wanted to change the world! So after many years working in IT, I started a business called The Little House Company selling Separett waterless toilets and urine diverters.

In 2013, after several requests, I began making wooden compost toilets, based around the Separett Privy 500 or Privy 501 urine separator. These were ultimately branded Eco-Loo.

Despite my tiny workshop (8ft x 10ft), I ended up producing well over one hundred Eco-Loo compost toilets, each one custom made and supplied in unfinished wood, wood stain or one of my signature ‘Farrow & Ball’ colours.

I stopped making compost toilets in 2018, and for a brief time, lent the brand name to another UK company (Kildwick). Until that point, all products were completely handmade, starting with a simple but sturdy wooden frame, matchboard cladding fixed over the top and a birch plywood top. This created a distinctive appearance which was enhanced with the optional Farrow & Ball paint colours.

During my time, I gained a huge amount of practical knowledge and experience in compost toilet construction, use thereof, and the composting process, particularly in respect to urine-diverting or urine-separating toilets. – I not only made them, but I used them too.

This website is my personal effort to bring a wider knowledge and understanding of compost toilets, help people choose the right compost toilet solution for them and understand the whole process from when you sit down to putting some wonderful compost on your garden!

Compost, composting, dry or waterless toilets might not be for everyone – there are some compromises and through the Bog Blog, I’ll explore some of these in more detail. Some types and styles will be more suited to some people or situations than others – knowing the pros and cons will help you choose wisely.

And don’t forget, that crapping into a porcelain bowl and flushing with 8 litres or so of clean drinking water is also a big compromise – it’s just that you pass the responsibility onto someone else so don’t have to personally deal with it. Some people don’t want to do that. Some people have no choice. I’m one of those people who thinks waterless toilets are better – are you?

PS I still want to change the world!
