Urine separation is the single most important part of any composting toilet — it's what keeps it odour-free. Our Complete urine separator is a full, ready-to-fit unit that diverts liquid away from solids at source, so the solids stay dry and the whole system is far easier to live with.

Handmade in Wales from solid 4 mm ABS with a removable metal filter and a 10-year guarantee, it's built to last. Whether you're fitting out a campervan loo, an off-grid cabin, a tiny home or a garden compost toilet, this is the part that turns it from smelly and awkward into clean, dry and genuinely pleasant to use.

Why urine separation makes all the difference

Almost all the odour in a composting or dry toilet comes not from solid waste but from what happens when urine and solids mix. Keep the two apart and the problem disappears: solids dry out and compost properly, the ammonia smell never develops, and you empty the system far less often. A urine separator isn't an optional extra — it's the foundation of a toilet that actually works.

Designed to fit — and how to get it right

We make the separator slimline on purpose, so it fits the widest possible range of toilet builds and seats. Because every build is a little different, it's designed to be positioned and adjusted to suit yours — get the position right and it catches everything cleanly.

• Mount it on the underside of the seat platform, on the inward slope — this gives a little extra clearance.
• Men: sit to use it, and if there's any contact with the plastic, add a thin spacer to lift the seat slightly — problem solved.

Built to last — and easy to keep clean

Made from solid 4 mm ABS — a tough, high-gloss material that wipes clean in seconds and keeps its colour and shape for years. A removable metal filter sits over the outlet to stop pipe blockages, and the whole unit lifts off for a deep clean in under a minute. Backed by our 10-year guarantee.

Easy to fit

Fix the separator to the underside of your seat platform with screws and connect the outlet to standard waste pipe — no specialist tools or plumbing knowledge needed.

Connecting your pipe: the tapered outlet fits standard 1¼" (32 mm) push-fit or solvent-weld waste pipe. Because push-fit and solvent-weld pipe differ slightly, the fit is a deliberate compromise so it works with both — if it's snug, lightly deburr the inside edge of the pipe, or use a 1¼" connector to slip it on easily. Then route the pipe to a soakaway, a collection container, or a dilution tank for liquid feed.
