TROBOLO urine diverter white - insert for DIY composting toilet
- TROBOLO urine diverter made of white polypropylene. It separates solids from urine, fits standard toilet seats and lets you drain urine through a DN32 hose.
The TROBOLO urine diverter is the heart of every composting toilet. This white polypropylene insert separates urine from solids right in the bowl, so both go into separate containers and are easy to dispose of. The insert fits any standard toilet seat, which makes it ideal for building your own toilet in a camper, cabin or garden, and as a spare part for TROBOLO toilets.

- anatomical design for reliable separation of solids and liquids regardless of the user's size, weight or gender
- adapter system with filter sieve that you can replace in seconds
- urine can go into a container or out through a DN32 hose
- smooth high-gloss surfaces for easy, hygienic cleaning
- solid design and replaceable parts for a long service life
- compatible with any standard toilet seat

How the urine diverter works
You use the toilet just like a conventional one. Urine is collected in the front part of the insert and drains into a separate liquids container, an external tank or a pipe. Solids pass without contact through the rear opening into a container lined with an inlay that you lift out and dispose of or compost. The deep-drawn collar of the rear opening protects the inside of the toilet from soiling.

The TROBOLO adapter system
The part that wears most is the filter sieve, as deposits build up on it over time. With the TROBOLO diverter you only replace the adapter, while the rest of the insert keeps working. The hose connector adapter takes a DN32 hose, so urine can go, for example, into the grey water tank of a motorhome. The integrated seal keeps every connection tight, and the sieve holds back paper and litter so the drain does not clog.
Fitting it in your own toilet
A cutting template is included for marking the opening in the lid of your box or cabinet. The inner opening of the insert is 310 x 240 mm, and the diverter itself measures 170 x 375 x 322 mm. You mount any standard toilet seat on top, which simplifies planning and buying materials.
