Urine Separator and Diverter for Composting Toilets



Urine separation is the single most important factor in any composting toilet.
This plastic urine separator diverts the wee away from the poo, to keep your compost toilet odour free and easy to maintain.

The solution to hassle-free urine separation: a nifty piece of plastic that is attached with runners or screws to the bottom of the compost toilet seat platform, and can be easily removed for periodic cleaning.

Strong and sturdy, with an easy-to-clean shiny surface, this urine separator is the outcome of extensive research into the most effective way of diverting urine away from the solids, for both male and female users.

 "Hiya Paul, I'm just putting the finishing touches to the wetroom- It's a million times better than the separett ones - well done.

I used the black waste hose on the urine spout and with a j clip, that little fat ridge you made gets it to hold perfect. Great work man"



Dear Free Range Designs

Hi, I just wanted to tell you how happy I am with the Urine separator. I have had a composting toilet (lovely loo) I made myself for about three years. It works great. I was dreaming about a "Nature's Head" toilet for my new Mini house but changed my mind. I looked into the Separatti but it would require me to build another toilet due to the shape. The separator you sell was easy to use with my existing loo and has really improved the quality of my life because I don't have to change out the composting buckets nearly as often.

Thank you!

"Thanks so much for the urine separator. I had been looking all over the internet and finally stumbled upon your site. Got it today and it works perfectly! "

Thanks Jay


"Hi there,

We're in the US. We ordered a urine separator from you earlier this year to put into our homemade composting toilet in our house. We like it so much better than the fancy "composting" toilet that we had previously and we'd like to get 2 more to put into outdoor toilets on our farm."

Thanks Kevin - USA


"We've installed a compost loo using your separator and it works brilliantly. We haven't had to put a drain or hole in the bottom of the wheelie bin we've used because there is very little build up of liquid.Thank you for all your help."
