Composting Toilet Urine Diverter and Ventilation Attachment turns your RV, Tiny Home, Cabin or favorite getaway bathroom into an affordable composting toilet.

The only Patent-Pending Urine Diverters designed to work with 5 gallon bucket set-ups! Though they are not limited to 5 gallon bucket set-ups, providing great flexibility, their unique design allows for maximum clearance for your bucket and solid waste. Other diverter styles impede your bucket, causing: you to dump the solids more often; have your bucket off-center, making your toilet housing enclosure way larger than necessary and compromised; they are bulky to the point your bucket will be far from the seat causing messy problems. Not with ours!

This is for a DIY or homemade composting toilet. It is a urine diverter, which separates liquids from solids, sending the liquids to a separate collection container. It sits only 1.75” from the top of the bucket to the top of the Urine Diverter. Urine Diverter only, hoses and tubes not included. Optional Ventilation Attachment sold separately, please check out the main shop! Urine Diverter works with .75" I.D. tubing that runs to a collection container (IMPORTANT: be sure the end of the tube, where the liquid exits, does not get submerged in the liquid along with the suggestion of using plumber/Teflon tape and a hose clamp to secure the tube to the diverter). Check my store for tubing availability or .75" tubing can be purchased at most hardware stores. Please message me with any questions!

-“Snap-On” model (snaps on top without cutting bucket with optional ventilation attachment, this model)

-“Mounted-Diverter” model (mounts to underside of toilet seat or toilet box/enclosure, other model)

--all work with or without bags

Made using High-Speed Industrial Additive (3D) Manufacturing Equipment.

Use Example:
It's for a homemade style of composting toilet to replace the toilet in an rv, tiny house, off-grid homestead, cabin, or what have you. In an rv, you can now open both tank gates and keep the cap on and double your grey tank while using no water for the toilet, more time in the woods without having to run to town. We put a 13 gallon bag in a 5 gallon bucket, sprinkle organic matter under and over the "business", we use those giant bags of cedar chips meant for gerbil bedding for the sprinkles (some use coconut husk, sawdust, etc.), and slide on the urine diverter which collects the liquid in a separate container. Build a housing around it and install a toilet seat. The liquid and solid separation takes care of the smell and the ventilation attachment helps, too. It makes everything less stinky and way easier to dispose of. Drain the liquid once every one or two days and take out the bag once a week with the trash or compost it. Works in setups without bags, as well.

Thank you!
