Throne Composting Toilet

Composting Toilet URINE DIVERTER

Regular price $95.00 USD
Regular price Sale price $95.00 USD

Composting toilets shouldn't be complicated, ugly, or expensive! A DIY toilet is a great option to save a bundle of money. However, the lynchpin item is the diverter and it can be difficult to find one that does its job well while keeping the cost reasonable. We developed a urine diverter that does its job exceptionally well, is simplistic in design and maintenance, looks pretty, AND saves you money.

The Diverter gives you the flexibility to craft the perfect toilet that fits your bathroom style and space! Simply build a base using the included plans and cut-sheet, add a bucket, jug, and fan and you have a toilet! The diverter separates the liquids from the solids in your composting toilet system which allows for increased solids capacity and easy disposal of the liquids. If you’re building a custom DIY toilet this part is the hardest to make on your own. Want to get the FREE Build Your Own Toilet plans now? Check them out here.

This diverter offers the best performance separating solids and liquids, the simplest cleaning, and the least fuss of any diverter we've found. A large solids opening means you don't have to aim your #2! A deep liquids bowl prevents overflowing during enthusiastic, well-hydrated use.
