About We-Pee

We make urine separators for composting toilets. That's all we do.

We've been at it since 2009 — designing, refining, manufacturing and shipping urine separators from our workshop in Wales to customers across the world.

In a world of generalist toilet brands, we're the specialists. One product family, made properly, made to last.

Why urine separation matters

Urine separation is the single most important factor in any composting toilet. When urine and faeces mix together, ammonia-producing bacteria thrive — that's the source of the unmistakeable compost-loo smell, and the reason so many DIY composting toilets fail.

Separate them at source and the smell vanishes. Your compost chamber stays dry, lighter, easier to empty, and the composting process speeds up dramatically. You get a system that actually works — pleasant to use, easy to maintain, and genuinely sustainable.

This isn't theory. It's the single biggest insight in modern composting toilet design, and it's what we've spent over 15 years building products around.

How it started

We-Pee began in 2009, born out of building our own off-grid compost toilet and discovering that the urine separator was the make-or-break component — but the only options at the time were expensive imports or unreliable DIY hacks.

So we made our own. We tested it. We iterated. We sold a few to friends and family who were building their own loos. People kept asking us to make more. We kept making them better.

Today we manufacture in the UK, ship worldwide, and have shipped well over a thousand separators to customers in 30+ countries — from off-grid homesteads in Hawaii to glamping sites in the UK, from tiny houses in Texas to allotment sheds across Europe.

Our products

We make two urine separators, both designed and manufactured in the UK from strong, durable plastic with a smooth, easy-clean shiny surface:

We-Pee Urine Separator — £31
Our original compact design, available in white and black. Fits under your toilet seat, connects to standard 1¼" push-fit waste pipe, and can be easily removed for cleaning. Works for both male and female users. The DIY-er's choice.

Complete Urine Separator — £40
Our newer full-unit design that sits as a complete assembly under the toilet seat. Includes a removable metal filter that prevents pipe blockages. Currently white only — black coming soon. The all-in-one choice.

Made in Wales

Our workshop is based in rural Wales, where we've been quietly making urine separators for over 15 years. Everything you order from us is manufactured here — not imported, not white-labelled, not drop-shipped from somewhere else.

We're a small team and our deliberate decision is to stay small. It means we know our product inside out, we answer our own emails, and we genuinely care that each separator works for the customer it's heading to.

Where our separators end up

Glamping sites and off-grid retreats. Boats and narrowboats. Allotment sheds and garden offices. Vanlife conversions. Tiny houses. Building sites and festivals. Aid projects in places with water shortages. Compost-toilet enthusiasts in countries we'd never heard of before they got in touch.

We love seeing where they end up. Take a look at some of our customer installs from around the world on the Customer Installs page.

Bulk & trade

If you run a glamping site, festival, eco-resort or development with multiple compost toilets, we offer tiered wholesale pricing on bulk orders. See our Wholesale & Trade page or get in touch.

Shipping

We ship worldwide. UK delivery is prompt and reliable. If you're based in Europe, we recommend purchasing through our eBay store or Amazon store for the smoothest post-Brexit delivery experience. Full details on our Shipping & Delivery page.

Sustainability

A composting toilet, used properly, saves around 25 litres of water per person per day compared to a flush system. Multiply that across a year and you're looking at 9,000 litres per person not poured down a drain.

Our separators are made to last — many of our 2009 customers are still using their original units. We chose durable plastic over biodegradable alternatives deliberately: a separator that lasts 20+ years keeps far more material out of landfill than one that needs replacing every five.
