It depends on where you are installing the toilet.

 In a Tiny Home which is only moved occasionally 95% of owners choose a Lifestyle toilet. The urine is piped outside to a large container or a soak pit. This means you don’t have to worry about the urine bottle filling up if you have a few guests over for a meal.

The Classic Eco Loo can be used in a Tiny Home as well but it is also is a great solution for a campervan or house bus where you don’t mind emptying the 9.5 litre urine bottle every two or three days. The other option for your campervan or house bus is to install a Lifestyle toilet and run the urine into the grey water tank if you have spare capacity.

Both the Classic and Lifestyle toilets are an approved solution for the 2025 Self Containment Regulations.

Our toilets have a 15 litres container, which should last two people 7 to 10 days before you have to empty them.

We strongly recommend it. We use two for extra strength.
Using bags makes emptying so much easier. Just lift the bag out when full, no cleaning required.

How long it lasts depends on how many people are using the toilet. A healthy adult produces .8 to 2 litres of urine a day. The volume can vary based on fluid intake, activity level and temperature of the day.

We recommend emptying the on-board container every three days, otherwise it gets a strong ammonia smell which is unpleasant when emptying.

If lots of people use the toilet, you’ll need to empty it more often. Our Eco-loos have an LED indicator telling you how full the urine container is.

Another option is to pipe the urine to a larger external tank or into a soak pit.

The fan removes moisture from the solids bucket and helps to keep things dryer. The fan also extracts smells when the toilet is used. In a tiny home this makes a big difference. Alternatively, you can operate a urine seperating toilet without a fan if you cover every poo with a handful of wood chips or another carbon-rich material.

If you notice a smell you need to use more cover. The disadvantage is your solids container fills faster and needs to be emptied more often

It won't compost in the toilet. Composting takes time, and happens in a larger external container or composting pile.

We prefer to use untreated wood shavings. You can usually get these free from joinery firms. You can also use shredded newspapers, large sawdust or wooden cat litter pellets. Any carbon-based material will do.

The important thing is to keep the solids tank as dry as possible. Excess moisture is the enemy.
