FAQs

What is a composting toilet?

A composting toilet, also known as an eco-loo, eco-toilet, waterless toilet or compost toilet, i.e. one that doesn’t use water to take the waste somewhere else. It also allows natural processes to produce natural compost that can be used on your garden.

Our composting toilets are known as ‘urine separating composting toilets’. So everyone sits down to use them, boys and girls. This enables the separation of liquid waste from solid waste. This stops all the nasty smells associated with composting toilets and they really do work. Its a simple design. Under the seat is a large container, into which you sprinkle a large scoop of sawdust, then it’s ready to use. When the container is full, you simple remove the lid off of the toilet, lift out the container and replace with a new one. The full container is then put in a corner somewhere to allow it to decompose.

What are the benefits?

  • The solid waste in a composting toilet, eco-toilet is dealt with on site and doesn’t have to be treated with chemicals in sewage farms, or end up in waterways.
  • Saves water – you don’t have to use one resource (pure drinking water) to flush away another (fertilizer).
  • Organic matter is allowed to go back to the soil where it belongs, improving soil structure and nutrition.
  • No need to use chemical cleaners or bleaches in the toilet. There are plenty of eco-friendly cleaners on the market or you can use distilled vinegar with a splash of lemon essential oil to make a really effective environmentally friendly cleaner.

Are they available in kit form?

Yes they are, if you already have a small shed that you wish to utilise for a loo then you can purchase the internal workings of our compost toilets to fit yourself. The kit is described on our loo page and costs £795 including delivery. (Highlands of Scotland and some other areas will incur an extra cost). To get a delivery quote please use our contact form. Let us know the post code and we will calculate the total cost for you.

What about vandals?

One of our latest products is a vandal resistent cubicle. It is made from powder coated galvanised metal with a three point locking system. It comes to you in kit form as we are not able to deliver these to you fully assembled. The size of the cubicle is 5ft wide x 4ft deep. In the kit you get the full internal workings including our non slip flooring, extra bins, etc, full details of this unit is available here.

Are they portable?

Yes they are. We have designed our timber compost toilets so that they are portable. They are lightweight but very sturdy, and all the working are completely contained within the cubicle. The exception is the urine container which sits outside the unit. The idea behind this, is for Certified Location (CL) campsites to be able to move the loos inside a barn during the closed season, making them complient under the CL rules. They do not require any mains water or sewage outlet either.

Do they smell?

No, they don’t smell. After each use, just drop a handful of ‘soak’ (straw or sawdust) into the toilet. This is because bacteria like to eat a balanced diet of carbon and nitrogen, and as human waste contains a lot of nitrogen, if they don’t get enough carboniferous material (like sawdust, straw or shredded paper) they will give off excess nitrogen in the form of ammonia, which makes the toilet smelly. Also the sawdust allows oxygen into the pile, and absorbs liquids. This allows the pile to decompose aerobically to produce nitrates, phosphates and sulphates. Without the sawdust the pile will decompose anaerobically and produce methane, ammonia and hydrogen sulphide – all very smelly and not very useful.

Human pathogens don’t like conditions outside the human body, so almost all will be dead after a few hours. Only one type of roundworm egg can survive a year-long decomposition period. It is recommended using the compost on fruit trees and bushes, not on the vegetable garden.

How do I dispose of the urine?

There are two choices to dispose of the urine. You can either build a soakaway next to where the composting toilet cubicle is going to be sited, or you can have the outlet pipe going into a container. This way you can then water the contents down – 8 parts water to 1 part urine – and use it on your compost heap to help speed up the decomposition of your ordinary garden waste. It also acts as a general fertiliser.

How long does it take for the solids to compost down?

This can take anything up to a year. It is necessary for the solids to be left for as long as possible before you start using it on your garden. It needs air to help it decompose, so leave it in the corner of your garden with the lid slightly loose and, before you know it, you will have great compost for your plants.

Is the timber used in the manufacture of the cubicles from a sustainable source?

Yes, 98% of the timber used is FSC accredited. The remainder comes from recycled timber that we purchase locally.

Are they fitted with a separate urinal? 

You have the option of having a separate urinal fitted to the large unit (1200mm x 1200mm) or disabled access unit (1550mm x 1550mm). The cost of the additional urinal unit is £350.00. They are a waterless urinal which goes into a separate container situated behind the cubicle.

What about disabled access?

Eco-loos largest unit is 1550mm x 1550mm and is suitable for most wheelchair users. The threshold of the door way is 100mm from ground level so a small ramp may be needed or the pathway leading to the cubicle may need to be raised slightly to allow for easier access. Please check that this size will be suitable for your needs. We do now offer an option of a 2000mm x 1550mm unit, but the delivery process is slightly different and we will be happy to discuss with you. It is worth noting that the doors on all our composting toilets open outwards. This is especially important in the disabled access toilet as this allows more space for a wheelchair user to manoeuvre once inside the cubicle. Due to the size, delivery of these disabled access units may be subject to additional delivery charges. They weigh around 135kgs and can be lifted by 4 people.

How do I pay for my composting toilet?

Once you have chosen the options we will send you a written quote. On receipt of the quote you can pay by bank transfer or you can send us a cheque. If you need to pay by credit card, we can send you a separate invoice to pay this way. Just call us or email us and request a written quote/invoice which will have all the payment options included.

What is the delivery charge?

Delivery charges start at £95.00 but will be more for certain areas e.g. Highlands of Scotland. When you are ready to place your order please let us know your delivery address and we will give you a quote for delivery.
